A Giant Right Coronary Artery Aneurysm Leading to Tricuspid Stenosis.

Giant coronary artery aneurysms (CAAs) are rare coronary artery anomalies. The management of CAAs is still controversial because of the different possible pathophysiologies. In our case, tricuspid stenosis resulting from compression of the giant CAA was successfully relieved by CAA repair. As far as we know, this is the first reported case of compression by a giant CAA resulting in tricuspid stenosis.
