Paravalvular Leak Closure
A paravalvular leak is a rare occurrence and happens when a replacement valve does not stay in place. When this happens, the valve allows small amounts of blood to flow around it or backward instead of through it. Large leaks can lead to heart failure and increase your risk for infection, so it’s important to get structural heart disease treatment right away. The good news is that a nonsurgical procedure can close the leak.
Paravalvular leak closure involves inserting small plugs or coils inside the gaps next to the replacement valve. Here’s how it works:
- Before structural heart disease treatment, you may undergo one or morecardiovascular imaging tests, such as an ultrasound of the heart, to pinpoint the source of your leak.
- We give you medication to put you to sleep and ease any discomfort.
- An interventional cardiologist makes an incision in your artery and inserts a thin, spaghetti-like tube (catheter) with the closure device attached.
- Your doctor guides the catheter through your blood vessels, delivering the closure device to the source of the leak.
- Using special instruments and advanced imaging technology, our experts permanently attach the closure device to your tissue or the valve to seal off the leak.
- We remove the catheter, and your procedure is complete.
- After the procedure, we perform additional imaging tests to make sure the closure is secure.
