I had my first echo 3 weeks post op, and since then I have been getting them every 6 months since my AVR surgery on Oct. 1 2013. However, my frequency is due to (a) an enlarged left ventricle that we are monitoring to see if it is going down and (b) trying to lower the dosage or ideally get me off of Coversyl and Metoprolol (which are being taken because of the enlarged left ventricle). So, we reduced my drugs early this year and I go back for an echo in July to see if there is any change - for the better or worse. Originally I was at 65mm pre surgery, then 66 mm immediately post op, then 62 a bit later and at the start of this year I was at 57mm. They think that may be as low as it goes (was at 18 months post op), but TBD (57mm is at the high end of the normal range). My EF was 60% but has since dropped to 55%, so they are monitoring that as well (Metoprolol and Coversyl can improve your EF, so with the drug dosage drop, we want to see if it impacts it. Eventually my echos will go to an annual basis.
