Giant coronary artery aneurysm causing superior vena cava syndrome and congestive heart failure.
Coronary artery aneurysms are defined as localized coronary artery dilations >1.5 times the diameter of the adjacent segments. In adults, they are commonly of atherosclerotic origin and are usually asymptomatic. This is the first case report of a coronary artery aneurysm causing superior vena cava syndrome and heart failure. Chest x-ray showed cardiomegaly, and transthoracic echocardiography showed a mass that was confirmed by transesophageal echocardiography, computed tomography, and coronary angiography. In conclusion, giant coronary artery aneurysms can cause superior vena cava syndrome.
