Biomechanical analysis of novel leaflet geometries for bioprosthetic valvesCentral MessagePerspective [PDF]

JTCVS Open, 2023
Objectives: Although bioprosthetic valves have excellent hemodynamic properties and can eliminate the need for lifelong anticoagulation therapy, these devices are associated with high rates of reoperation and limited durability.

Long‐Term Outcomes of Patients Undergoing Aortic Root Replacement With Mechanical Versus Bioprosthetic Valves: Meta‐Analysis of Reconstructed Time‐to‐Event Data [PDF]

Journal of the American Heart Association: Cardiovascular and Cerebrovascular Disease, 2023
Background An aspect not so clear in the scenario of aortic surgery is how patients fare after composite aortic valve graft replacement (CAVGR) depending on the type of valve (bioprosthetic versus mechanical).

Dynamic Echocardiographic Imaging of a Valve-in-Valve Mitral Prosthesis

Case Reports in Radiology, 2022
Dynamic imaging of heart valves and specifically prosthetic valves is a central benefit of echocardiography. Most bioprosthetic heart valves degenerate over a given time and hence require repeat valve replacement which carries a significant risk of ...
