sexymexican888  ALSO remember that this is probably due to posteromedial papillary muscle because it only has 1 blood supply (PDA from RCA if right dominant, from LCX if left dominant) while the anterolateral papillary muscle has dual blood supply. This of course is in the left ventricle -> papillary muscle rupture -> mitral regurgitation +1
chaosawaits  At risk of sounding like a complete moron, why isn't A pulmonary regurgitation, B tricuspid stenosis, C pulmonary stenosis, D PDA, and E VSD? +
chaosawaits  Rephrase: why isn't A) aortic or pulmonary regurg, B) mitral stenosis, C) pulmonary stenosis, D) PDA, and E) VSD +
