What Determines the Durability of a Cow Tissue Heart Valve?

How long can a cow tissue valve replacement last? In this video, Dr. Marc Gillinov, Chairman of Cardiac Surgery at the Cleveland Clinic, explains the expected durability of bioprosthetic heart valves and why their lifespan can vary from one patient to another. He discusses how factors such as patient age, valve position, and overall health may influence how long a replacement valve continues to function effectively.

Dr. Gillinov also explains why lifelong follow-up care is important after heart valve replacement surgery. Patients will learn how echocardiograms help doctors monitor valve performance, what may indicate structural valve deterioration, and which treatment options could be considered if a tissue valve eventually needs additional care.
