Abstract

|
Anomalous origin of the right coronary artery(RCA) with interarterial course is a rare but lift-threatening anomaly causing sudden death in young adult. A 70-year-old male was admitted with chest pain and epigastric discomfort. At initial evaluations, he took anti-ulcer medicine in the impression of gastric ulcer and gastroesophageal reflux disease from the other department. With regardless of treatment, he felt chest discomfort intermittently. At abdominal CT scan, infrarenal abdominal aortic aneurysm (3.4x3.3 Cm) was found, but he was transferred cardiologic department for the conservative treatment because the size is not indicated for operation. We performed coronary angiogram to rule out ischemia due to continuous chest pain and found that RCA arises from the os of left main coronary artery and runs forward between ascending aorta and pulmonary arterial trunk. His chest pain was improved with beta blockers and angiotensin receptor blockers.
