“Watch me deliver a presentation to a group of surgeons on this tricky case. A complication of open surgical valve replacement, with a tricky hole was left behind. I managed to plug it and reduce the leak. The patient has felt so much better ever since!”

What is a paravalvular leak?

After surgical valve replacement, leaks can sometimes occur. Either THROUGH  the valve – or  BY THE SIDE  of it – due to a weakness in the tissues which allows the sutures to loosen. If the leak is severe enough, the valve can even start “rocking”. 

In this particular case that I presented, however, a suture seemed to have created an additional hole, connecting the left ventricle to the right atrium. This is what’s known as a Gerbode Defect.

What treatments are there for Paravalvular Leak?

There are several options:

  • Medical therapy. If you’ve got no symptoms and the heart is stable, it may not be necessary to close the leak. Not every hole needs closing.
  • Transcatheter device placement. Plug it with a transcatheter device put in from the leg.
  • Redo surgery. If the surgical risk isn’t too high and a plug’s not possible, re-doing the surgery will likely be your best option.

What tests do I need?

For a suspected paravalvular leak, you’ll need a full assessment. This includes:
