Abstract

There are many causes of sudden cardiac arrest. The main cause of sudden cardiac death (SCD) is coronary heart disease. However, the frequency of coronary heart disease is much lower in sudden cardiac arrest occurring below the age of 30-40. Congenital anomalous origin of the coronary arteries is a rare, but well-described, cause of myocardial ischemia and sudden death in young adults. Here, we report the case of a 23-year-old man with sudden cardiac arrest due to ventricular fibrillation associated with an anomalous origin of the right coronary artery. The patient was diagnosed using multi-detector computed tomography and successfully treated with surgical correction.
