Looks pretty darn good (from a lay person's perspective). Your heart size and function are normal for your height and weight. The 66% vs 61% was probably a visual vs calculated estimate of your ejection fraction - it's basically the same number and means nothing. Both 61 and 66% would be considered absolutely excellent.
Sounds like you have a trace of mitral regurgitation, which usually means nothing at all. I'm not sure about aortic regurgitation.
That's all I know :)
I'm not a doctor, but I have looked at my share of echo reports. :) This one looks really good, to me. I don't see anything on the report that looks concerning. Your doctor MAY want to get a repeat echo at some point, but he/she will let you know. Some (trivial, pysiologic, mild) regurgitation is pretty common, so your doctor will consider your age, overall health, etc. and decide whether a follow up is even necessary. He/she may also suggest preventive antibiotics prior to dental procedures, etc. Just check with your doctor and follow his/her advice.
