Insights
A 74-year-old man presented with chest pain and dyspnea due to multiple giant coronary artery aneurysms (CAAs). One ruptured into the right atrium, causing myocardial infarction. Surgical repair was successful.
Area of Science:
- Cardiology
- Cardiovascular Surgery
- Diagnostic Imaging
Background:
- Coronary artery aneurysms (CAAs) are rare, often asymptomatic vascular dilatations.
- Giant CAAs are particularly uncommon and associated with increased risk of rupture and complications.
- Myocardial infarction and cardiac rupture are severe, life-threatening sequelae of untreated CAAs.
Abstract:
A 74-year-old man was admitted to our hospital with chest pain and dyspnea associated with ST elevation in leads II, III and aVF. An echocardiogram showed an enlarged mass lesion measuring nearly 80 mm. Coronary angiography showed two giant coronary artery aneurysms (CAAs) in the right coronary artery (RCA). CAAs were also seen in the left main trunk and left anterior descending artery. Computed tomography showed the CAA in the RCA was ruptured into the right atrium. We therefore diagnosed this patient with multiple CAAs, myocardial infarction and coronary artery rupture. He underwent successful surgical excision and coronary bypass surgery.

Coronary Circulation
Coronary circulation begins at the base of the aorta, where two main arteries arise—the left and right coronary arteries. These arteries encircle the heart in the coronary sulcus and supply the...
