Percutaneous exclusion of a rapidly enlarging left main coronary artery aneurysm using coils and an Amplatzer™ septal occluder

Abstract

Coronary artery aneurysms (CAAs) are often an incidental finding amongst patients undergoing coronary angiography. Most CAAs are managed conservatively; rarely a larger CAA can lead to intramural thrombus formation and coronary artery embolization/obstruction even without the presence of significant stenosis. Despite these clinical implications, therapeutic options are limited to case reports and no clearly defined guidelines have been established for treatment. In this article, we present a unique case of a rapidly enlarging left main CAA, with no identifiable etiology that was treated with percutaneous exclusion via coil embolization and an Amplatzer™ septal occluder device. We also discuss existing literature, pathophysiology, and management options for CAAs. © 2016 Wiley Periodicals, Inc.

Rationale and design of a multicenter, international and collaborative Coronary Artery Aneurysm Registry (CAAR)

“…Goals are to define the natural history of the disease (epidemiology, aneurysm growing patterns, etiologies), whether the clinical presentation (acute or not) should modify our management strategy, main medical treatment aspects (eg, antiplatelet therapy, how and for how long, need for anticoagulation), revascularization strategies (interventional or surgical approaches preferred, and when), and, for angioplasty procedures, if we should choose drug‐eluting stents or covered stents rather than others …”
