A Giant Thrombosed Right Coronary Artery Aneurysm Presenting as an Obstructing Left Atrial Mass.

Abstract

Giant coronary artery aneurysms are exceedingly rare. Symptoms are vague and often related to myocardial ischaemia or compression of a cardiac chamber. Surgery is indicated when obstruction to the circulation results in heart failure or syncope, as in our case. A clear elucidation of the pathology may not be possible before exploration and the surgical strategy is tailored to the individual case.
