    Abstract:
    Background: 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 on a complex procedure and complications still occur in approximately 9% of patients. Case Report: 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. Conclusion: Aorta-left ventricle communication could be a relative contraindication to be assessed on a case-by-case basis, but transcatheter closure does not preclude subsequent attempt for surgical repair and outcome.
