Isolated right coronary lesion and anterolateral papillary muscle rupture - case report and review of the literature

Ischemic rupture of the anterolateral papillary muscle is uncommon due to its dual blood supply. It usually follows an ischemic event involving branches of the left circumflex or left anterior descending arteries. We present a case of a patient admitted with an acute inferior wall myocardial infarction and an isolated distal right coronary artery occlusion. Acute mitral regurgitation with rupture of the anterolateral papillary muscle was diagnosed on the fifth post-infarction day. The patient underwent mitral valve replacement and coronary artery bypass grafting to the posterior descending artery. We conclude that anterolateral papillary muscle rupture may also result from an isolated right coronary lesion

A 54-year-old male patient developed acute onset of chronic aortic dissection manifesting as primarily abdominal pain. A prompt diagnosis was made and urgent surgery was carried out successfully under profound hypothermic circulatory arrest. Prompt surgery is mandatory for such patients in order to prevent abrupt rupture. The awareness of possible aortic dissection is the key point leading to an early diagnosis in patients with atypical presentations
