Well, I can spell it, but I can't pronounce it--and the short answer (SPOILER ALERT!) is that I'm not going under the knife anytime soon. However, it--like the rest of life--is complicated.
The TEE (transesophageal echocardiogram), by the way, didn't quite go quite as promised. Here's what was supposed to happen: numb throat, insert drugs, nod off, and wake up with lovely images of my heart, courtesy of a miracle device snaked down my throat. As it turns out, the 'numb throat' part involved the doctors squirting lidocaine gel down my throat and asking me to gargle with it (!)--and the numbing, alas, did not last the duration of the procedure. "Ah," you think, "but you were unconscious!" Well, not so much. Whatever morphine mixture they were pumping into me might have relaxed me, but I was quite awake the whole time. The good news? Nice clear images, apparently.
According to my cardiologist (Hey! I have a cardiologist! Imagine that!) basically said that my valves, as we expected, are not working properly, for reasons vaguely and graphically explained here. On a scale of one to four, my mitral valve is leaking at level two, which is not inconsistent with MVD (which, by the way, is a bit unusual for someone my age). However, my aortic valve--normally unaffected by MVD--is leaking at level three. And there appear to be some issues with my tricuspid valve.
What happens next? Assuming I don't suffer from shortness of breath, swollen ankles, or heart palpitations in the near future, I go back for a checkup in six months. Long-term, it sounds as though surgery is inevitable, but, for the moment, everything appears to be functioning normally.
