Multicenter Study Comparative StudyStentless sutureless and transcatheter valves: a comparison of the hemodynamic performance of different prostheses concept.
Stentless aortic valves have been developed to overcome obstructive limitations associated with stented bioprostheses. A new concept of surgical sutureless (SU) bioprosthesis has been developed in the last decade. In this multi-institutional study we sought to compare hemodynamics of different bioprosthesis concept as transcatheter (TAVR), Livanova Perceval S sutureless valve and Freedom Solo Stentless (FS) valve in patients undergoing aortic valve replacement (sAVR). ⋯ SU patients demonstrated post-operative excellent hemodynamic performance with smaller EROA and higher gradients compared to FS and TAVR. TAVR demonstrated higher mortality and pacemaker rates. Further studies are warrented to validate TAVR indications in this subset of patients.
