JUAN A. CRESTANELLO: Welcome to the Cardiovascular Surgery Series, where I review the latest research in cardiovascular surgery from the Mayo Clinic in just 2 minutes. I will review today the article entitled, Prosthesis choice for tricuspid valve replacement-- comparison of clinical and echocardiographic outcomes.

Between 1993 and 2018, we performed more than 1,000 tricuspid valve replacement. We use bioprosthesis in the majority of the patients and mechanical valves in only 149 patients. We found that the long-term survival and the rate of reoperation was similar between bioprosthesis and mechanical valves. The rate of tricuspid regurgitation recurrence was lower with mechanical valves.

More importantly, the recovery of right ventricular size and function was similar between mechanical valves and bioprosthesis. Based on those results, we recommend to use mechanical valves only in young patients with older mechanical valves in other positions or with other reasons for anticoagulation. Thank you for listening to the Mayo Clinic Cardiovascular Surgery Series.
