A significant number of clinical studies have investigated the long-term outcomes of mechanical valves and bioprostheses. Prosthetic heart valves are associated with several complications including structural valve deterioration, nonstructural dysfunction, valve thrombosis, embolism, bleeding event, endocarditis, and reoperation. The American College of Cardiology / American Heart Association Guidelines for Reporting Morbidity and Mortality After Cardiac Valve Interventions provide a precise definition of these complications (See Table). These guidelines represent a useful framework for investigating these events after heart valve surgery.
Below we report the long-term results of mechanical and bioprosthetic aortic valve replacement. We have included clinical studies published during the last decade with a minimum follow-up of five years. If you click on each variable you will visualize the corresponding table. Each table can be reorganized according to the parameters included in the first row allowing the reader to analyze the data in a more personalized manner.
