In the ‘80’s, my mother had a mitral valve replacement. They used a pig valve. It only lasted about ten years. She required large amounts of anti-rejection drugs. All that may no longer be necessary with this new technology.
I had a mechanical valve replacement in 2013 as part of a ruptured ascending aorta aneurysm surgery. That just has been replaced with a bovine valve due to endocarditis. The surgeon’s skill, medical technology, and the grace of God has kept me alive. My fear though is that as sure as you are born, you are destined to die. Does man really have the wisdom to go forward by further trying to alter that pattern?
