Does anybody recommend a top cardiologist in the Seattle area

I do not know any more databases, but I used to work with Dr. Gordon Kritzer when he was in Connecticut, and he is excellent.
However, it sounds like you might be asking for a cardiothoraccic surgeon.If your father is already scheduled for surgery, he must already have a cardiologist. Who performed the cardiac catheterization? They can refer your dad to a surgeon,too.
Good luck. :>)

Try healthgrades.com. However, I believe Dr. Christopher Price is in the Seattle area. Just North of Seattle, I believe. He is one of the best doctors I've ever had the pleasure of working with and he actually trained at our institution. You might want to look him up. I'd recommend him without reservation to any patient. Good luck.
