Hello everyone:
I recall very well, when my husband has his first heart surgery, two valve replacements, that his surgeon was VERY specific about this issue. (He had his surgery done by Dr. Vlahakes at Mass General). He told both of us that recovery from his surgery would be longer, and more difficult than by-pass. That often the medical professionals might treat him as a by pass patient, but he was not, and the recovery would definitely take longer. He was right. Unforunately, even his local cardio thought the same thing, until an echo was done, and it was found that his tricuspid valve had a severe leak, and that, combined with the surgery itself, and the chronic a-fib, have contributed to a less than optimal recovery. He is now scheduled for his second heart surgery this month, to repair that valve, and then get a pacemaker. What Dr. Vlahakes did say, was that for the mitral replacement, the heart did have to be incised, and the heart itself had to recover from that trauma. Combine that with going "on pump".....there you have it. I am sure, however, that age, other medical issues a person might have, might contricute to the overall recovery. Each person enters that operating room with a different set of circumstances, not the least of which is the staff standing there waiting for them.
