Acute mitral regurgitation can be precipitated by acute myocardial infarction due to rupture of the anterolateral papillary muscle, which requires prompt echocardiographic diagnosis and surgical intervention.
May inform rare post-MI papillary rupture cases; leaves open generalizability and optimal strategies pending larger data.
BACKGROUND: The rupture of the anterolateral papillary muscle is less common than the posteromedial papillary muscle since the anterolateral muscle has dual blood supplies, while the posteromedial papillary muscle has a single blood supply. CASE PRESENTATION: We present a case report of a 42 year old male presenting with heart failure being diagnosed to have mitral regurgitation from the partial rupture of the anterolateral papillary muscle due to coronary artery disease. The patient underwent a mitral valve replacement and concomitant coronary artery bypass grafting of the first and the second obtuse marginal arteries. CONCLUSION: Acute mitral regurgitation can be precipitated by acute myocardial infarction due to rupture of the anterolateral papillary muscle.

Jayawardena et al. (2008) conducted a case report in Anterolateral papillary muscle rupture caused by myocardial infarction (n=1). Mitral valve replacement and coronary artery bypass grafting was evaluated. Mitral valve replacement and concomitant coronary artery bypass grafting successfully treated a 42-year-old male presenting with acute mitral regurgitation due to anterolateral papillary muscle rupture following myocardial infarction.
