Ruffian -
Sorry if my mention of “increased risk of sudden cardiac death” alarmed you; I may not have been clear that it is not believed to be valid today.
My main point in posting was to convey how changeable medical dogma can be. It sounds like you got caught in the crossfire of changing views of what is, and what is not, MVP, and what does & what does not require SBE prophyllaxis. In the early '90’s as an internist, I spent a great deal of time “undiagnosing” MVP in patients who at sometime in their life had been told they had a heart murmur, had an ECHO, and because of poorly defined diagnostic criteria were told that they had MVP, needed SBE prophyllaxis, and had an increased risk of premature death. For the active duty soldiers I was seing, this sometimes was enough to keep them from going to schools they wanted to attend (Special Forces/SEALs have very rigorous health standards) & serious implications on their ability to get promoted.
There is a tendency among a good many young healthy patients (we sometimes call them the worried well) to equate playing it safe and giving them a diagnosis they may or may not have with good medical care. From your second post, it seems clear that my concern that this may have applied to you was unfounded. It also sounds like you are well on your your way to getting this resolved, once & for all.
Bottom line: If no murmur is heard, no amount of prolapse (valve “parachuting” back into the atrium) means anything.
Even if a murmur is heard, the ECHO should confirm that there is mitral regurgitation (blood flowing backwards across the mitral valve from the L ventricle to the L atrium during pumping=systole) before SBE prophyllaxis is required. There are other causes of audible murmurs that are entirely benign, and need no further evaluation or treatment.
