Transcatheter aortic valve-in-valve implantation and sutureless aortic valve replacement: two strategies for one goal in redo patients

The most appropriate approach for high-risk patients with degenerated bioprostheses remains a matter of debate. The aim of the study was to evaluate the clinical and hemodynamic outcome of redo patients undergoing transcatheter aortic valve-in-valve implantation (VinV-TAVI) and sutureless aortic valve replacement (AVR), with assessment of patient-prosthesis mismatch (PPM) in the perioperative and follow-up period.
