Surgery for delayed leaflet impingement after transcatheter closure of a
paravalvular leak associated with an aortic pseudoaneurysm
Abstract
Paravalvular leak (PVL) is a recognized and challenging complication
after surgical or transcatheter valve replacement. The transcatheter
closure of PVL has become the first-line treatment in clinical practice
when the procedure is not contraindicated. Transcatheter PVL closure
rests a complex procedure and complications still occur in approximately
9% of patients. We describe the case of a delayed mechanical prosthetic
leaflet impingement after transcatheter closure of a paravalvular leak
associated with a Valsalva pseudoaneurysm that required an urgent
surgery. The transcatheter closure of PVL does not preclude subsequent
attempt to surgical repair and outcome.
