Core valve embolization: Technical challenges and management

Transcatheter Aortic Valve Implantation with the Core Valve self expanding prosthesis can be complicated by hemodynamic instability in cases of low deployment (implant failure). The management of a low implant may necessitate repositioning the prostheses with the help of a snare catheter. Snaring can however be complicated by embolization of the prosthesis which presents a series of technical challenges that need to be addressed. We have discussed the technical issues and the approach to address them successfully in a systematic manner to ensure optimal procedural and patient outcomes. © 2011 Wiley Periodicals, Inc.
