[HSF] Mitral ring redux

[Tea Acuff]

I would like to raise the issue as to why this patient has a dilated myopathic ventricle. With a LV dimension of 7 cm he must have a large ESV and EDV but the exact numbers would be reassuring for consideration prior to intervention. It is very doubtful that his MR is causative or even contributory at this point. Most likely he has a substantial ant/septal infarction which likely can be "cured" or stabilized with SVR. This may or may not even require direct surgical annular narrowing. Undoubtedly this clinically based on population studies occurs over and over and is largely missed as this thread would suggest. A cardiac MR would be very helpful to make this diagnosis, but as Ani would argue the odds are (in such population) that SVR would help the majority of the patients with this description and should be ruled out before deciding on alternative therapy. It may be quite difficult to make a clear intra op decision without opening the LV because of
 frequent lack of full thickness scarring and the primary endocardial pattern of scarring. If you are not aggressively inclined to do SVR on this population, you will very likely  not make the correct assessment intra op.

Being well aware of Bolling's work, I opted not to get into a pissing match 
with my colleague.

Nonetheless, he does have a left bundle, about 0.16- 0.18. By echo and on 
the V-gram, his anterior wall moves, albeit sluggishly.
