“… 2 , 4 Small CAAs are often asymptomatic and may not require resection, whereas giant CAAs produce symptoms. 8 Dyspnea, chest pain, and palpitations are the common symptoms of giant CAAs. 4 The chances of rupture increase if the size of the aneurysm exceeds 30 mm.…”

“…Most CAAs reported were treated surgically by placing the patient on CPB, resecting the aneurysm, and installing a bypass graft using a saphenous vein or the internal mammary artery. 8 This approach hinges on achieving a stable heart rhythm and other hemodynamic parameters while occluding the coronary artery proximal to the aneurysm during the procedure. In our case, the resection of the aneurysm and the plication of the arterial margins were successfully undertaken using CPB.…”

Coronary artery aneurysms (CAAs) occur when an artery dilates 1.5 times the reference vessel. They occur most commonly because of atherosclerosis. CAAs are a rare phenomenon, and it is even rarer to find a giant CAA, which is roughly defined as a size 400% above the reference vessel. Giant CAAs are commonly found in the right coronary artery. The sinoatrial nodal artery (SNA) is among the least common sites for CAA involvement. Sometimes, communication exists between the aneurysm and a chamber of the heart or a great vessel. The consequences of the fistula depend on its size. Because of the rarity of the condition, guidelines are not well developed. However, small CAAs can be managed conservatively, whereas giant CAAs require resection, ligation, and bypass grafting. CAAs have a predilection for males and the elderly. We describe a 40-year-old South Asian woman presenting with mild dyspnea on exertion of 1 year’s duration. Echocardiography showed a 60×60 mm cystic sac, subsequently confirmed by computerized tomography, which showed 3 large aneurysms (70×61 mm) and 3 small aneurysms in the SNA. Coronary angiography illustrated that the SNA branched off the left main coronary artery, and the aneurysm communicated with the right coronary artery. The aneurysm was partially resected and plicated.
