français vers anglais Médecine Médecine (général) Diagnosis - heart disease abbreviation

An elderly patient whose summary I am translating.

There is a listing in his medical history introduced by the title:

MCAS
s/p PAC + PMC 1985, stents x2 sur PAC 1997

I take MCAS to mean CAD
s/p = status post
PAC - coronary artery catheterization

I am uncertain about PMC.

Any help would be greatly appreciated!

Thanks!
