I had a blood clot in a typical echo and was on blood thinner for months, Ef fraction was 35% but now is normal 55%. They repeated the Echo and tester claimed she had some difficulty reading an area and is not recommending a TEE, where they put a probe down your throat and repeat the procedure. I love when they do the echo report they use such big terms that I have no idea what they are saying. Question: do I need to do a TEE if the Echo doesn't show any particular issues? Or is my Dr just test happy?
