Coil embolization for distal left main aneurysm: a new approach to coronary artery aneurysm treatment.

Coronary artery aneurysm is an uncommon disease, whose natural history and therapeutic approach are still controversial: medical therapy, surgical revascularization with or without aneurysm ligation or excision, and endovascular exclusion with membrane covered stents are all accepted and viable options, according to anatomic characteristics. Intracranial aneurysms are adequately treated by means of coil embolization, an option that, to our knowledge, has never been tested in coronary interventions. We report the first case of a coronary aneurysm involving the distal left main and the proximal left anterior descending artery treated with "stent-assisted" coil embolization.
