I asked my surgeon about his statistics. He said that he didn't know, but that he did 100+ valves last year with no problems and most of the patients were considerably older and at risk for complications than me. On the internet, I found all of two comments, one glowing the other complaining about how their father died and the surgeon didn't communicate enough. I did find that he was involved with and led surgical clinical trials. To me this meant he was at least "up-to-date". I checked my state site and there were no disciplinary actions. I asked the doctor who referred my surgeon why him, and he had no personal knowledge of him, the referal came from the cardiac surgery scheduling group. I decided to trust the gods of medicine and not look back, and all has been well.
Per ratings of hospitals and doctors, I don't hold much faith in them. The US News and World Report listing of hospitals does not list the one I went to. It lists a competing hospital in my city as being one of the best, which IMHO, has an equal if not lower reputation compared to the unrated hospital. The highly rated hospital had trouble with its heart program and actually took doctors from the un-rated hospital to upgrade their facility. The highly rated hospital ended its transplant program due to scandal (years ago), but the un-rated one has had a successful program for years. Personally, I think the programs are equivalent, but the un-rated hospital is not-for-profit and not a state institution, thus it doesn't have as much visibility.
