Abstract:
Percutaneous closure of paravalvular leaks is becoming a more widely practiced technique. We describe the technique we used to deploy an Amplatzer PFO closure device to treat a prosthetic mitral paravalvular leak. The procedure was performed under real time 3D trans-oesophageal echo and fluoroscopic guidance requiring a trans-septal puncture and utilising an 035″ Safari wire which was developed for TAVR implantation. An excellent result was achieved acutely and at 4 month follow-up. © 2016 Wiley Periodicals, Inc.
