Congenital and Atherosclerotic (Acquired) Coronary Artery Aneurysms: Coronary Angiographic and Morphologic Observations in 10 Patients

Three-vessel coronary artery disease with multi-vessel proximal aneurysms

We report the case of a 47-year-old man, referred for chest pain radiating to jaws associated with sweating. At coronary angiography, left anterior descending coronary artery was occluded with distal perfusion by collateral flow, and proximal coronary aneurysms involving proximal left circumflex (LCX) right coronary artery with diffuse coronary atherosclerosis were present. Coronary thrombosis was also present into LCX proximal aneurysm.

Giant Pseudoaneurysm From Vieussens' Arterial Ring

A giant coronary pseudoaneurysm of uncertain cause, arising from Vieussens' arterial ring, was preoperatively diagnosed in an oligosymptomatic female patient. Successful off-pump surgical excision without additional bypass grafting was performed. Difficulties in diagnostic algorithm, as well as possible cause and extremely rare localization were discussed.
