Hemodynamic Comparison of the On-X and Top Hat Mechanical Aortic Valve Prostheses

CONCLUSIONS: There was no difference between the two valves with respect to the AV area index at discharge, and hemodynamic function was stable during longer-term follow-up. The longer aortic cross-clamp time observed in the On-X group may indicate increased complexity in implantation compared to the Top Hat group.PMID:38636685 | DOI:10.1016/j.athoracsur.2024.04.003
