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.

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.
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. (Sat,) 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.
