“…The 1998 FDA objective performance criteria for the mechanical valve patient population for TE averages 5 . The linearized rates of TE reported in the mechanical valve literature range from 0.6% to 3.5% per patient‐year, 2–9,20–23 whereas the linearized rates of TE for tissue valves range from 0.6% to 3.9% per patient‐year 11,14,15,17,19,22 …”

“…This review demonstrated that mechanical and tissue valves in both aortic and mitral positions have equivalent ranges for TE (0.6%–3.5%/patient‐year and 0.6%–3.9%/patient‐year, respectively) 2–9,11,14,15,17,19,20–22 . A possible explanation for this is that as tissue valves deteriorate they often demonstrate calcification, ulcerations, and thrombus, which may cause TE.…”

This review provides general guidance for heart valve selection. Mechanical heart valves exhibit excellent durability and hemodynamic performance but require anticoagulation to reduce thromboembolism, and therefore risk of anticoagulation-related hemorrhage is increased. Tissue valves were introduced to avoid anticoagulation, but in fact often do not, and lack durability. A literature review was performed to compare the complications of thromboembolism, anticoagulation-related hemorrhage, reoperation structural valve deterioration, and reoperative mortality associated with mechanical and tissue valves. The thromboembolism rates for mechanical and tissue valves are equivalent. During their lives, many recipients of tissue valves receive anticoagulation therapy due to comorbid conditions. The anticoagulation-related blood loss rates associated with mitral mechanical valves and mitral tissue valves are equivalent, whereas the blood loss rates associated with aortic tissue valves are less than those associated with aortic mechanical valves.
