Ventricular fibrillation resulting from acute right ventricular infarction from isolated occlusion of a right ventricular branch artery.
Malignant ventricular arrhythmias can result from isolated right ventricular infarction, and reports of this phenomenon in the literature are rare. We present a case of a 46-year-old man with acute onset of chest pain angiographically confirmed to be a result of isolated occlusion of a right ventricular branch artery. He developed ventricular fibrillation within 5 hours of symptom onset. This case highlights the point that despite its benign clinical appearance and preserved left ventricular function, necrosis of right ventricular tissue can have life-threatening consequences.
