A 64-year-old woman had undergone coronary artery bypass grafting (CABG) for right coronary occlusion and the Dor procedure for a left ventricular apex aneurysm 10 years previously. A follow-up computed tomography scan showed the evolution of a giant coronary artery aneurysm (CAA) located on the proximal left circumflex artery (CX). It also revealed a previous saphenous vein graft (SVG) that was patent and located on the midline. Surgical exclusion was regarded as invasive, and isolated percutaneous intervention was unsuitable for a wide-necked CAA. Thus, a hybrid approach was planned. First, CABG (SVG-CX) via left thoracotomy was performed. Following the surgery, stent-assisted coil embolization was performed. A coronary angiogram revealed complete CAA exclusion. LEARNING OBJECTIVE: Many authors have reported successful repair for coronary artery aneurysm (CAA) with a percutaneous approach or surgery. Although there is no consensus for giant CAA repair, surgical repair including resection, ligation, and coronary artery bypass grafting have been recommended in previous reports. However, every decision should be tailored to suit each condition. In this case with the history of previous cardiovascular surgery, our hybrid approach was thought to be less invasive and feasible than isolated surgical or percutaneous repair. |
