Гидротрансформаторы АКПП. Устройство, Ремонт, Типичные проблемы, Болезни

Гидротрансформатор — это внешний узел автоматической трансмиссии, который передавая крутящий момент от двигателя к трансмиссии служит для разгона при помощи двух вращающихся в масле турбин, ведомой и ведущей) и амортизации (и трансформации) вращательного момента от двигателя.

Гидротрансформатор часто называют по имени своего предшественника: «гидромуфта», потому что он соединяет как муфта (сцепление) двигатель с коробкой. Блокируясь с помощью фрикциона сцепления, гидротрансформатор выключается, передавая момент напрямую, без потери мощности.

На сленге мастеров гидротрансформатор из-за своей формы называется «бубликом«.

Гидротрансформатор, хотя и вынесен за пределы конструкции АКПП, является частью коробки передач, потому что управляется гидроблоком через общую гидравлическую систему трансмиссии. А его неисправности напрямую влияют на работу маслонасоса, гидроблока и на ресурс всей коробки, как (подробнее — ниже).

Функции гидротрансформатора: 

— Беречь трансмиссию на пиковых нагрузках от двигателя, старт и торможение. (Амортизация, функция демпфера и гидравлической жидкости между турбинами)

— Повышение момента вращения. Само название «Гидротрансформатор» или Torque Converter произошло от того, что при разгоне происходит примерно 2-х кратное увеличение вращающего момента за счет такого же кратного уменьшения скорости вращения на выходном валу. Чем выше скорость (и меньше ускорение) — тем меньше эта кратность.

Немного об истории Гидротрансформатора

Первая гидромуфта была изобретена в 1902 году и установлена в 1907-м на скоростном судне. В 1928 году фирма «Lysholm—Smith» впервые примени

90000 6 Symptoms of a Bad Transmission Valve Body (and Replacement Cost in 2020) 90001 90002 Updated 90003 June 10, 2022 90004 90005 90002 A transmission valve body is a major component of an automatic transmission. It’s essentially a maze-like control center made up of valves, passageways, and solenoids that diverts transmission fluid to where it’s needed for gear changes. 90005 90002 90009 Looking for a good online repair manual? 90010 Click Here for 5 of the most popular options. 90005 90002 While not a common part to fail, when you do have some type of malfunction in the transmission valve body, it’s not a simple fix.Your options are either to replace or rebuild it. 90005 90002 Here is how an auto trans valve body works along with common signs and symptoms you may experience when a transmission valve body is bad. 90005 90016 How a Transmission Valve Body Works 90017 90002 All automatic transmission systems have a valve body which serves as the «brain» of the transmission. 90005 90002 There are dozens of various passages and channels within the valve body which direct the flow of pressurized hydraulic fluid to different valves in order to activate the right clutch pack or band and shift to the most appropriate gear based on the current driving situation.90005 90002 Think of each channel as a tumbler on a lock which has to perfectly line up so transmission fluid is directed where it should. 90005 90002 The valves that make up the valve body each serve a different purpose and their names reflect what they do. For example, the valve body has a 2-3 shift valve which is responsible for up shifting from 2nd gear to 3rd gear. 90005 90002 And if there’s going to be a downshift from 4th gear to 3rd gear, then the 4-3 shift valve would be responsible for that.90005 90002 90029 90029 90005 90016 Types of Valve Body 90017 90002 There are two main types of valve body. The first type is the 90009 electronic valve body 90010 which uses the electronic system ECT (electronic controlled transmission) as its main control to operate all shifting on an automatic transmission. 90005 90002 Many newer cars use this electronically controlled transmission (ECT) which has bands and clutches that are operated via hydraulics. 90005 90002 However, an electric solenoid valve is used to control each hydraulic circuit.This is what allows the transmission to have more elaborate and advanced control schemes than non-electronically controlled transmissions. 90005 90002 The controller of the transmission can monitor the throttle position, vehicle speed, anti-lock braking system, and the engine speed. 90005 90002 The other type of valve body is called the 90009 hydraulic valve body 90010. This system works by using hydraulic pressure to control each valve that’s linked to the shifting lever. 90005 90002 When you change the handle’s position, it will uncover and cover certain passages in the valve body to accommodate that position.So, if you were to change the gear lever to «Drive,» then fluid would be directed into the clutch and 1st gear would be activated. 90005 90016 6 Common Symptoms of a Bad Transmission Valve Body 90017 90002 If you have a failing automatic transmission valve body, there are some clear symptoms that you should look out for. 90005 90054 # 1 — Harsh or Delayed «Garage Shifts» 90055 90002 90057 90057 90005 90002 One of the most common signs you have a problem with your transmission valve body is a delay (2 or more seconds) or harsh shift when shifting from Park to Drive or Park to Reverse.These are commonly referred to as «garage shifts». 90005 90002 If you have a problem with only one scenario (example: Park -> Reverse), try to limit the amount of times you’re in that situation even if it means backing into the garage or a parking space each time. 90005 90054 # 2 — Incorrect Up or Down Shifting 90055 90002 90067 90067 90005 90002 While driving, you may notice that your transmission is shifting into a higher or lower gear at the wrong time. 90005 90002 For instance, you may be going up a hill and even though you want the transmission to shift down to give you more power, it instead shifts into a higher gear making the drive up the hill much more difficult.90005 90002 In addition, you could be driving a steady 60 MPH on a level highway and your transmission sporadically shifts into either a higher or lower gear for no reason. Any type of erratic shifting can be a symptom of a bad transmission valve body. 90005 90054 # 3 — Shift Flares 90055 90002 90079 90079 90005 90002 When everything in your transmission is working correctly, in between every shift the engine RPM should briefly decrease on an up-shift (ie: 3rd to 4th gear) to match up with the higher gear.90005 90002 A «shift flare» is when the opposite occurs: the engine RPM instead increases on an up-shift. 90005 90054 # 4 — Banging or Knocking Sounds 90055 90002 90089 90089 90005 90002 If you hear a banging or knocking sound as your gears change while accelerating (up-shifts) or slowing down (down-shifts) or when putting your car into reverse, that may be an indication of a faulty valve body. 90005 90054 # 5 — Gear Slippage 90055 90002 90097 90097 90005 90002 While it could be something else like low transmission fluid or worn transmission bands, when your transmission slips out of gear while driving, it could mean your valve body is going bad.90005 90002 With a slipping transmission, your vehicle may try to up-shift but then quickly falls into a lower gear. Or it may even refuse to shift into a higher gear which makes your engine run at a higher RPM than usual. 90005 90054 # 6 — Check Engine Light On 90055 90002 90107 90107 90005 90002 If you experience any of the symptoms above and your check engine or malfunction indicator lamp (MIL) comes on, it’s a good idea to scan your vehicle for stored diagnostic trouble codes . 90005 90002 Since the transmission valve body is responsible for so many functions of the transmission, many transmission related DTC codes can pop up.These may include P0715, P0751, P0783, P0829, P2707, among others. 90005 90002 It is easy to ignore these kinds of symptoms in the beginning because they may not be so bad. But the problems with your valve body will often become more clear when you drive your car continuously for at least 30 minutes and your transmission fully heats up. 90005 90002 If you experience any of these problems, it’s advisable to take your vehicle to an auto repair shop and ask a mechanic for their expert opinion. 90005 90016 Transmission Valve Body Replacement Cost 90017 90002 90121 90121 90005 90002 Replacing your automatic transmission valve body is no easy task, which means it’s not cheap.For a complete job (parts + labor), expect to pay somewhere in the vicinity of $ 390 to $ 860. 90005 90002 Parts alone cost on average $ 250 to $ 500 but expect to pay more for certain makes such as Mercedes, Volvo, Porsche, and others. Labor costs for the 2-3 hour job will be around $ 140 to $ 360 depending on if you go to an independent mechanic or dealership. 90005 90002 You can slightly reduce your costs by purchasing a re-manufactured valve body assembly if one is available for your vehicle. 90005 90002 90131 90009 Note: 90010 Before agreeing on replacing the valve body, make sure the issue is simply not a bad transmission solenoid by getting a second opinion from a different shop.Replacing a transmission solenoid is much cheaper. 90134 90005 90016 Replace vs Rebuild 90017 90002 Some transmission repair shops might offer the option of rebuilding your current valve body instead of replacing with a brand new (or remanufactured) one. This can sometimes save you some money, especially for some higher end cars. But should you do that? 90005 90002 Generally speaking, if you have a higher mileage car (100,000 miles or more), you should simply replace your valve body. For lower mileage cars, rebuilding the current transmission valve body is a fairly good option if you’re dealing with a good transmission shop.90005.90000 Functions & Failure symptoms of automatic transmission valve body 90001 90002 What are the functions of an automatic transmission valve body? What are the symptoms of a failing automatic transmission valve body? Click to now find out. 90003 90004 In a vehicle’s auto transmission system, the auto transmission valve body is such an important component that works in a form of network. This valve body helps put together suitable clutch packs for the smooth functioning of the gear by directing pressurized transmission fluid to its network of valves within.When the gear in the car changes the speed from high to low or low to high, the valves make use of the pressure of hydraulic signals in determining the gear set to use. This process is known as servomechanism or just servo. 90003 90002 90007 Naijauto.com 90008 thinks it’s necessary to understand some of the 90009 key functions of this auto transmission valve body 90010 as well as the failure symptoms so that car owners and drivers can be well informed. Read on. 90003 90012 90007 1. Automatic transmission valve body — Key functions 90008 90015 90002 A valve body serves as the central control center in an automatic transmission system.This valve body normally has numerous channels and passages within itself. And it switches the gear according to the current driving circumstance. It also helps to direct the right clutch by allowing hydraulic fluid to flow to different valves. The manual valve is the most significant part of the valve body itself. As it is connected to the gear stick handle in the car, this valve body instructs the correct passage for the hydraulic fluid to pass through smoothly. 90003 90002 90003 90002 90021 An auto transmission valve body serves as the central control center in an automatic transmission system 90022 90003 90002 The modern types of auto transmission valve body now have sensors which monitors the engine load when performing a soft or firm gear shift as well as monitors the throttle position, brake pedal position and speed.These sensors collect and sends crucial info to the onboard computer responsible for engine management. Redirection of hydraulic fluid to the correct clutch pack is done by an electrically controlled solenoid which is actually directed by this same automatic transmission valve body. 90003 90012 90007 2. Automatic transmission valve body — Failure symptoms 90008 90015 90002 A car owner or driver will definitely be faced with issues when changing gears as well as have an affected driving ability when the transmission valve body is bad.Most of the symptoms of a bad auto transmission valve body is fairly noticeable especially with extended usage of such a vehicle in that condition. And in reality, you should be able to use a vehicle with bad transmission valve body for too long. Here are some of the main failure symptoms that you should attend to on time. 90003 90032 90007 2.1. Banging or Knocking noises 90008 90035 90002 You might be hearing some knocking or banging noises whenever you are slowing down carefully or applying pressure to the brakes.And even when you are driving the car backwards or putting it on reverse, you might start to hear some awkward sort of noises. If you notice any of this happening to your car, chances are that your transmission valve body is bad and needs attention soon. 90003 90002 90003 90002 90041 The banging or knocking noise when changing speeds indicates problems in the automatic transmission valve body 90042 90003 90032 90007 2.2. Slipping stick when shifting gear 90008 90035 90002 There is likelihood of a major problem with your vehicle’s transmission valve body if you realize that when changing the gears, the shifting stick slips recurrently.If your transmission valve body was functioning properly, then you should not be experiencing a slippage of the shifting stick. 90003 90002 90041 90009 >>> Recommended for you: 5 most common clutch problems: How to detect and repair them yourself 90010 90042 90003 90032 90007 2.3. Downshifting issues 90008 90035 90002 When the hydraulic fluid is having difficulties entering the transmission valve body correctly, your transmission will most likely have difficulties in downshifting.And once this starts to happen, you will notice your gears malfunctioning and resulting to degraded overall vehicle performance. 90003 90002 90063 90064 90003 90002 90021 Valve Bodies — Carl’s Tech Talk 90022 90003 90032 90007 2.4. Shifting delays 90008 90035 90002 It’s also common to face problems when changing gears to drive or reverse if you have a bad transmission valve body or a malfunctioning valve body. Consequence of this is, a greater delay occurring during shifting of the transmission.When you start seeing the signs of this, you should be prepared as your car might subsequently starts getting stuck in the neutral gear. 90003 90012 90007 3. Conclusion 90008 90015 90002 Having said all of the above, we think its good to also inform you that detection of a bad transmission valve body is relatively easy. An engine management computer in a modern vehicle will always activate a kind of warning light on the vehicle’s dashboard which is serving as an alert for the driver at that time.So, if you pay attention and never ignore some of the warning lights on your dashboard and you regularly check what car component, those lights are alerting you about, you should be good to go. Do not ignore warning lights on your vehicle’s dashboard. 90003 90002 Meanwhile, if you are looking for used cars with 90007 excellent transmission valve body 90008 conditions, then you should check out our huge collections of 90007 New, Tokunbo, and Nigerian used cars for sale in Nigeria. 90008 90003 90002 90041 90007 >>> Check for more driving tips and car maintenance advice on Naijauto.com! 90008 90042 90003 .90000 Aortic Valve Disease: Symptoms, Causes, and Risks 90001 90002 Aortic valve disease is a condition that occurs when your aorta (the main artery of your body) and left ventricle (the lower left chamber of your heart) malfunction. The aortic valve determines how blood flows from your left ventricle to your aorta. 90003 90002 There are two different types of aortic valve disease: aortic stenosis and aortic regurgitation. In the case of aortic stenosis, the opening of your aortic valve is narrower than it should be resulting in restricted blood flow to the aorta.In aortic regurgitation, some of the blood leaks back into your left ventricle because your aortic valve does not close tightly enough. 90003 90002 While both forms of aortic valve disease share similar symptoms, such as chest pain during exercise that eases when you’re at rest, they do have a few different symptoms. Aortic stenosis may cause: 90003 90008 90009 swollen ankles 90010 90009 fatigue 90010 90009 shortness of breath 90010 90009 rapid or fluttering pulse 90010 90017 90002 Aortic regurgitation can cause: 90003 90008 90009 fainting, usually during physical activity 90010 90009 coughing 90010 90009 heart palpitations 90010 90017 90002 Both types of aortic valve disease may take a number of years to appear.As a result, you should tell your doctor if you experience these symptoms and have — or have had — any of the conditions that would put you at risk of it (such as rheumatic fever or scarlet fever). 90003 90030 Aortic Stenosis 90031 90002 A buildup of calcium on your aortic valve’s leaflets can also cause aortic stenosis. As blood flows through your heart, calcium gradually builds up on the leaflets. The calcium deposit can cause the leaflets to stiffen and narrow your aortic valve. This form of aortic valve disease usually only appears in older adults.90003 90002 Rheumatic fever and scarlet fever can also cause aortic stenosis. Rheumatic fever and scarlet fever can begin as strep throat and then leave scars on your aortic valve. The scars can cause your aortic valve to narrow. This scar tissue may also give calcium a surface where it can collect. 90003 90030 Aortic Regurgitation 90031 90002 Aortic regurgitation shares some of the same causes as aortic stenosis, but it is sometimes caused by simple wear and tear. Your aortic valve opens and closes thousands of times per day.As time goes on, normal wear may cause the valve to malfunction. The worn valve may allow blood to flow back into your left ventricle. 90003 90002 Endocarditis is an infection of the valves of your heart that can also cause aortic regurgitation. Although rare, syphilis, a sexually transmitted disease, can also damage your heart valves. Even more rare, heart valve damage is also a side effect of a disorder of the spine called ankylosing spondylitis. Both types of damage can also cause aortic regurgitation.90003 90002 One cause of aortic regurgitation is a congenital heart defect present at birth. The valve of the aorta is typically made up of three triangular flaps called leaflets. When working properly, the leaflets fit tightly together, allowing blood to flow in only one direction. If you have a congenital defect, your aortic valve may only have one (unicuspid) or two (bicuspid) leaflets instead of the usual three. This type of aortic regurgitation may not show any symptoms until adulthood, when the valve finally begins to show signs of leaking.90003 90002 Both types of aortic valve disease are diagnosed in similar ways. Your doctor will likely ask you questions about your health history, as well as the health history of your family. You doctor may order an electrocardiogram, a test done usually in the office that measures electrical impulses from your heart to provide information on heart rhythm, exercise tests to measure how your heart responds to exertion, an echocardiogram, a test that uses sound waves to create an image of your heart and aortic valve.A chest X-ray is also commonly used to diagnose aortic valve disease. 90003 90002 Your doctor may suggest a cardiac catheterization if these tests do not provide a definitive diagnosis. This procedure uses a dye to highlight any leaks in your heart valves. The dye is injected through a vein in your groin or arm and then tracked on a monitor as it moves through your heart. The doctor may also order a cardiac magnetic resonance imaging test that uses magnetic field and radio waves to provide detailed pictures of your heart and aortic root.90003 90002 There are currently no medications available to treat the valve problems of aortic stenosis or aortic regurgitation, but your doctor can prescribe medications that can help reduce the effects of the disease. 90003 90030 Medications 90031 90002 In the case of aortic regurgitation, medication can lower your blood pressure and prevent the buildup of fluid. If you have aortic stenosis, your doctor may recommend the use of drugs to control disturbances in your heart’s rhythm. Beta and calcium blockers can help with angina (chest pain).Your doctor may also prescribe statin drugs to lower your blood cholesterol levels. 90003 90030 Surgery 90031 90002 While there are several surgical methods of treatment for aortic valve disease, the most common and most effective is aortic valve replacement. In this procedure, a surgeon will remove your damaged aortic valve and replace it with a new one from a human donor or a large animal, such as a cow or pig. 90003 90002 Your surgeon may opt for a mechanical valve. These are made of metal and are sturdy, but they increase your risk for blood clots in the heart.If you have a mechanical valve, you may need an anticoagulant drug such as warfarin (Coumadin) for permanent management of your condition. 90003 90002 Rather than replace the valve, your surgeon may choose to repair it with a procedure called a valvuloplasty. Unlike valve replacement, this method does not require long-term use of medication after your operation. 90003 90002 Among infants and children, a balloon valvuloplasty may be performed. During this procedure, a surgeon inserts a thin tube with a balloon at the tip into the child’s body.The surgeon guides the balloon to the aortic valve and inflates it. As it inflates, the balloon stretches the opening of the valve and improves blood flow. This type of valvuloplasty is usually not performed on adults, due to the likelihood that the valve would narrow again later on. 90003 90002 You can take steps to lower your chances of developing aortic valve disease. To lower your risk of aortic valve disease, you should try the following: 90003 90030 Preventing rheumatic and scarlet fever 90031 90002 If you have a sore throat, you may want to have it checked by your doctor to make sure that it’s not strep throat.Strep throat could progress into something that could damage your heart. 90003 90030 Practicing good dental hygiene 90031 90002 Make sure that your teeth and gums are well cared for. This reduces the chance of bloodstream infections that cause endocarditis. 90003 90030 Keeping your heart healthy 90031 90002 If you have high blood pressure or high cholesterol, talk to your doctor about steps you can take to lower them. Both of these conditions have close links to aortic valve disease. 90003.90000 Heart Valve Disease | NHLBI, NIH 90001 90002 Currently, no medicines can cure heart valve disease. However, lifestyle changes and medicines often can treat symptoms successfully and delay problems for many years. Eventually, though, you may need surgery to repair or replace a faulty heart valve. 90003 90002 The goals of treating heart valve disease might include: 90003 90006 Medicines 90007 90002 In addition to heart-healthy lifestyle changes, your doctor may prescribe medicines to: 90003 90010 90011 Lower high blood pressure or high blood cholesterol.90012 90011 Prevent arrhythmias (irregular heartbeats). 90012 90011 Thin the blood and prevent clots (if you have a man-made replacement valve). Doctors also prescribe these medicines for mitral stenosis or other valve defects that raise the risk of blood clots. 90012 90011 Treat coronary heart disease. Medicines for coronary heart disease can reduce your heart’s workload and relieve symptoms. 90012 90011 Treat heart failure. Heart failure medicines widen blood vessels and rid the body of excess fluid.90012 90021 90006 Repairing or Replacing Heart Valves 90007 90002 Your doctor may recommend repairing or replacing your heart valve (s), even if your heart valve disease is not causing symptoms. Repairing or replacing a valve can prevent lasting damage to your heart and sudden death. 90003 90002 The decision to repair or replace heart valves depends on many factors, including: 90003 90010 90011 The severity of your valve disease 90012 90011 Whether you need heart surgery for other conditions, such as bypass surgery to treat coronary heart disease.Bypass surgery and valve surgery can be performed at the same time. 90012 90011 Your age and general health 90012 90021 90002 When possible, heart valve repair is preferred over heart valve replacement. Valve repair preserves the strength and function of the heart muscle. People who have valve repair also have a lower risk of infective endocarditis after the surgery, and they do not need to take blood-thinning medicines for the rest of their lives. 90003 90002 However, heart valve repair surgery is harder to do than valve replacement.Also, not all valves can be repaired. Mitral valves often can be repaired. Aortic and pulmonary valves often have to be replaced. 90003 90040 Repairing Heart Valves 90041 90002 Heart surgeons can repair heart valves by: 90003 90010 90011 Adding tissue to patch holes or tears or to increase the support at the base of the valve 90012 90011 Removing or reshaping tissue so the valve can close tighter 90012 90011 Separating fused valve flaps 90012 90021 90002 Sometimes cardiologists repair heart valves using cardiac catheterization.Although catheter procedures are less invasive than surgery, they may not work as well for some patients. Work with your doctor to decide whether repair is appropriate. If so, your doctor can advise you on the best procedure. 90003 90002 Heart valves that can not open fully (stenosis) can be repaired with surgery or with a less invasive catheter procedure called balloon valvuloplasty. This procedure also is called balloon valvotomy. 90003 90002 During the procedure, a catheter (thin tube) with a balloon at its tip is threaded through a blood vessel to the faulty valve in your heart.The balloon is inflated to help widen the opening of the valve. Your doctor then deflates the balloon and removes both it and the tube. You’re awake during the procedure, which usually requires an overnight stay in a hospital. 90003 90002 Balloon valvuloplasty relieves many symptoms of heart valve disease, but may not cure it. The condition can worsen over time. You still may need medicines to treat symptoms or surgery to repair or replace the faulty valve. Balloon valvuloplasty has a shorter recovery time than surgery.The procedure may work as well as surgery for some patients who have mitral valve stenosis. For these people, balloon valvuloplasty often is preferred over surgical repair or replacement. 90003 90002 Balloon valvuloplasty does not work as well as surgery for adults who have aortic valve stenosis. Doctors often use balloon valvuloplasty to repair valve stenosis in infants and children. 90003 90040 Replacing Heart Valves 90041 90002 Sometimes heart valves can not be repaired and must be replaced. This surgery involves removing the faulty valve and replacing it with a man-made or biological valve.90003 90002 Biological valves are made from pig, cow, or human heart tissue and may have man-made parts as well. These valves are specially treated, so you will not need medicines to stop your body from rejecting the valve. 90003 90002 Man-made valves last longer than biological valves and usually do not have to be replaced. Biological valves usually have to be replaced after about 10 years, although newer ones may last 15 years or longer. Unlike biological valves, however, man-made valves require you to take blood-thinning medicines for the rest of your life.These medicines prevent blood clots from forming on the valve. Blood clots can cause a heart attack or stroke. Man-made valves also raise your risk of infective endocarditis. 90003 90002 You and your doctor will decide together whether you should have a man-made or biological replacement valve. 90003 90002 If you’re a woman of childbearing age or if you’re athletic, you may prefer a biological valve so you do not have to take blood-thinning medicines. If you’re elderly, you also may prefer a biological valve, as it will likely last for the rest of your life.90003 90040 Ross Procedure 90041 90002 Doctors also can treat faulty aortic valves with the Ross procedure. During this surgery, your doctor removes your faulty aortic valve and replaces it with your pulmonary valve. Your pulmonary valve is then replaced with a pulmonary valve from a deceased human donor. 90003 90002 This is more involved surgery than typical valve replacement, and it has a greater risk of complications. The Ross procedure may be especially useful for children because the surgically replaced valves continue to grow with the child.Also, lifelong treatment with blood-thinning medicines is not required. But in some patients, one or both valves fail to work well within a few years of the surgery. Researchers continue to study the use of this procedure. 90003 90040 Other Approaches for Repairing and Replacing Heart Valves 90041 90002 Some forms of heart valve repair and replacement surgery are less invasive than traditional surgery. These procedures use smaller incisions (cuts) to reach the heart valves. Hospital stays for these newer types of surgery usually are 3 to 5 days, compared with a 5-day stay for traditional heart valve surgery.90003 90002 New surgeries tend to cause less pain and have a lower risk of infection. Recovery time also tends to be shorter-2 to 4 weeks versus 6 to 8 weeks for traditional surgery. 90003 90086 Transcatheter Valve Therapy 90087 90002 Interventional cardiologists perform procedures that involve threading clips or other devices to repair faulty heart valves using a catheter (tube) inserted through a large blood vessel. The clips or devices are used to reshape the valves and stop the backflow of blood.People who receive these clips recover more easily than people who have surgery. However, the clips may not treat backflow as well as surgery. 90003 90002 Doctors also may use a catheter to replace faulty aortic valves. This procedure is called transcatheter aortic valve replacement (TAVR). For this procedure, the catheter usually is inserted into an artery in the groin (upper thigh) and threaded to the heart. A deflated balloon with a folded replacement valve around it is at the end of the catheter.90003 90002 Once the replacement valve is placed properly, the balloon is used to expand the new valve so it fits securely within the old valve. The balloon is then deflated, and the balloon and catheter are removed. 90003 90002 A replacement valve also can be inserted in an existing replacement valve that is failing. This is called a valve-in-valve procedure. 90003 90006 Heart-Healthy Lifestyle Changes to Treat Other Related Heart Conditions 90007 90002 To help treat heart conditions related to heart valve disease, your doctor may advise you to make heart-healthy lifestyle changes, such as: 90003 90040 90041.
