I do not mean to be the downer, but I have NEVER had a Cardio listen to my heart and assume that he had all the info to state the heart function was all good. I find that a little careless for your consultant to stop at just listening. There is much to be learned by additional testing. What if the heart function and/or size is changing? He could not tell that by listening. It may not be important now, but to be able to look year to year at the changes and the rate of changes could be beneficial.
I recognize that Cardios can tell a lot by listening. I even had a resident/fellow tell my Cardio that I had a Homograft valve just by listening, but I think he already new I had had a AVR.
Before my 1st AVR, my Cardio felt he knew my heart just by listening. He still did Echos. In the end, every 2nd opinion Cardio told me I needed surgery. I had surgery, and had a great recovery. Later, I ran into my previous Cardio who had the gall to say he still did not think I needed surgery. He was dead wrong, took chance with MY life and let his ego get in the way.
