Comparative StudyHemodynamic Comparison of Sutureless and Rapid-Deployment Valves with Conventional Bioprostheses.
Sutureless and rapid-deployment bioprostheses (RPDs) are advantageous due to shorter aortic cross-clamp times (ACCs); however, few studies have investigated hemodynamic outcomes in comparison to conventional bioprostheses (CBs). ⋯ RPDs provided comparable hemodynamic performance, although implanted valves were larger in true ID. Whether this provides superior hemodynamic performance during exercise and longer durability needs further investigation. Among RPDs, the Intuity valve provided lower mean gradients at rest than Perceval valve.
