It is one of the most important decisions for patients as they prepare for heart valve replacement surgery. That question is, “Which type of heart valve replacement device should I choose?”
There are several considerations that patients and their caregivers must evaluate relative to this question. Such considerations include durability, patient age, ongoing drug therapy, lifestyle, valve noises, activity levels, etc. I specifically remember creating a pros-and-cons list with Robyn (my wife) for each option prior to my own aortic valve replacement surgery.

Another patient consideration specific to mechanical and tissue valve selection is failure rates. As you can read in prior blogs, patients want to avoid valve replacement re-operations should the device fail while functioning in the human heart.
Unfortunately, I have been unable to locate published heart valve failure rates specific to each type of pig valve, cow valve, mechanical valve and homografts.
However, I just reviewed a very interesting study published by The Washington School Of Medicine about pig valve replacement failure rates that made my eyebrows jump to the top of my forehead. Here are the highlights from that study:
