Help me solve the real-life mystery about my late brother-in-law (apologies for novella-like length)

[DSeid]

@choie

…his heart had… uh, something that Carla doesn’t remember, possibly beginning with “mitra” or “myocardio-” (she obviously wasn’t paying close enough attention)… the point is, it’s evidence of damage from cocaine use. (Anyone know what it could be? Possibly something to do with the mitral valve?) …

Cocaine-Related Cardiomyopathy most likely.

My condolences as well.
