Adult Echo TTE for Examination prior to chemotherapy

In preparation to my second chemotherapy cycle with the scaries list of side effect, for example, heart problems or lymph cancer after a year or so -- I was sent to get Echo TTE

Echo TTE ---Transthoracic means on the chest wall. An echocardiogram is an ultrasound test of the heart,  using sound waves to create computerized outlines of the heart and its attached blood vessels.

Takes about 40 minutes and by the end of the day I got a clean bill of health. I wonder if they do it again after the chemo cycle is over to check for the damage...
