Prosthetic Paravalvular Leak (PVL) Repair

Procedure Stops Leakage Around Artificial Heart Valve

Sometimes a heart valve that is replaced with an artificial one can develop a leak around the new valve. This occurs most commonly due to infection, but technical factors such as the amount of mineral/calcium around the valve can play a role as well.

Small leaks may cause no symptoms. Larger leaks can cause problems such as congestive heart failure, hemolysis (a condition where blood cells are damaged by passing through the channel of a leaking valve leading to low blood counts—anemia), and increased risk of future infections.

Doctors can study the size and location of the leak using an echocardiogram (ultrasound of the heart) and CT scans.

In some patients, larger leaks are repaired by open-heart surgery. In other cases, an experienced and specially trained interventional cardiologist can repair these leaks with a nonsurgical procedure. The physician inserts a tube called a catheter into a blood vessel in the groin area. The catheter is advanced through the blood vessels to the site of the leaking heart valve. Using X-ray and cardiac ultrasound equipment, the doctor implants one or more specialized closure devices to plug the leak.

Is Prosthetic Paravalvular Leak Repair Right for You?

If you have had a heart valve replacement—especially the mitral valve or aortic valve—and there is moderate to severe leakage around your artificial valve, your doctor may recommend a procedure to repair the leak. 

Symptoms of valve regurgitation (blood backing up into the pumping heart chamber) include:

  • Fatigue
  • Shortness of breath
  • Heart murmur
  • Rapid or fluttering heartbeats
  • Swelling in your ankles or feet

In some cases, you may not have symptoms, but a repair may prevent the condition from worsening or relieve the workload on your heart. Your doctor may also determine that your anemia might be a result of this leakage and suggest further evaluation for closure of this leak.
