Abstract
We report a rare case of myocardial infarction complicated by anterolateral papillary muscle rupture and right ventricular infarction in a 49-year-old man. Initial signs suggested pulmonary embolism, but imaging revealed inferolateral infarction with right ventricular involvement. Angiography showed a thrombosed obtuse marginal branch supplying a chronically occluded right coronary artery. Despite intervention, the patient developed refractory cardiogenic shock. Surgery revealed complete papillary muscle rupture; mitral valve replacement and bypass were performed, but the patient died postoperatively. This case highlights the fatal potential of uncommon infarction patterns and the limited success of surgery, emphasizing the need for alternative transcatheter strategies in high-risk cases.
