Dear Anthony,
Yes it is very usual for "trivial' leaks of the mitral and tricuspid valve to appear on one echo and not the other- MOST ESPECIALLY IN NORMAL INDIVIDUALS!!!
People who are in to fitness, athletes that is, often have heart sizes that are in the upper limits of normal. This concept is very well studied and it has never been shown to be a detriment to the athlete unless the measurements are way above normal. I would consider your echo findings normal also and your doctor will need to give you the normal values that you ask for as they can vary from lab to lab and machine to machine. Good Luck and great job staying in good health with regular exercise. I hope that this information has been useful, please feel free to write back with any further questions.
