I require aortic valve replacement. i have excellent insurance and am very financially secure. where and by whom would you/should i go for it?

Ask your local : Ask your local physician that you trust most, feel comfortable after seeing the recommended surgeon.

Wrong place to ask: This is the public HT site where docs scattered primarily throughout the US answer questions about health conditions. We have no access to insurance lists or specialty sites for the many locations around the world where this site is seen. Your personal physician would be a good place to start the process of finding an available surgeon.
