Percutaneous paravalvular leak closure after TAVI: A demanding approach (original) (raw)

This correspondence discusses the complexities associated with percutaneous paravalvular leak (PVL) closure following transcatheter aortic valve implantation (TAVI) using a CoreValve device. It emphasizes the necessity for a thorough preoperative evaluation and the complexities of accessing the prosthetic frame, particularly the risks connected with crossing the nitinol struts and the importance of procedural techniques to minimize complications. The authors highlight essential considerations regarding access heights and the potential for inadvertent repositioning of bioprostheses during the procedure.
