10-YEAR ANGIOGRAPHIC COURSE OF A GIANT AN EURYSM OF THE CIRCUMFLEX ARTERY

Pathological dilatations of the coronary arteries are not exceptional and are called megadolichoartery, aneurysm or ectasia. Cases of marked arterial dilatation, although much rarer, are regularly reported foll owing their discovery due to the impressive angiographic, echocardiogr aphic or autopsy findings. However, their course, particularly in the long term, remains unclear. The authors report the case of a patient w ith a very large spindle-shaped aneurysm of the circumflex artery whos e course was able to be followed over a period of ten years on three s uccessive angiographic assessments performed for clinical coronary eve nts. This follow-up was dominated by thrombosis of the aneurysm, exten sion of the aneurysmal disease and severe deterioration of left ventri cular function.
