Re Severe Aortic Stenosis. Thank you for your answer Since Then I have had angio 50mm/hg valve and seen a surgeon for pre op. Many things i thought of as just aging are symptomatic of the condition and i will meet with anaesthesiologist and others in two days. Surgeon hopes to do Minimally invasive (as do I ) . No longer able to go up stairs w/o severe loss of breath, and have had a few mini TIAs in the last 5 years. Turns out the aortic narrowing was not the problem it is the valve.
