How's your squash game? I'm 62 and will have my aortic valve replaced along with a section of the ascending aorta in April. Looking most to getting back to squash, but will likley tend more towards doubles. Still struggling with bioprosthetic vs mechanical, though leaning towards mechanical so that I am one-and-done. Your experience, basically no problems after 16 yrs, is great but seems not typical. Anything you attribute it to (and you can't say a shot of scotch every afternoon)?On May 2, 2005, my bicuspid aortic valve was replaced by a wonderful, brilliant surgeon with an Edwards Perimount Magna (bovine pericardial), along with a graft of my ascending aorta. If you do the math, I've had the valve for (almost) 16 years. It has served me well through multiple (non heart-related) medical issues and procedures, and it's still going strong, with very little calcification. I know (from VR posts and from others) that tissue valves have been trouble for some, but I have had none. My age is 76. Questions?
