Spontaneous resolution of multiple coronary aneurysms complicating drug eluting stent implantation

Recent reports of coronary aneurysm formation after drug eluting stent implantation have emerged. Although various treatment modalities have been proposed, minimal data is available relating to their natural history and optimal management. We present a case of aneurysm formation in the left anterior descending and right coronary arteries after stenting with paclitaxel-eluting stents. Coronary bypass grafting of the left anterior descending and circumflex coronary arteries was subsequently required. Repeat angiography (16 months later) showed complete resolution of both coronary aneurysms. Spontaneous resolution of potentially drug eluting stent-related coronary aneurysms is documented. This phenomenon may have therapeutic implications.
