Quizplus · Accepted Answer

Damage to the papillary muscles of the mitral valve can lead to mitral valve regurgitation, which can cause left ventricular dysfunction and ultimately result in catastrophic left heart failure. Extension of myocardial damage, pulmonary edema from right heart failure, and pulmonary embolism are all possible complications of MI but are not directly related to papillary muscle damage.
