A 50-year-old woman presented to our hospital with Canadian Cardiovascular Society grade III angina of 4 months duration. Coronary angiography of the patient showed the absence of left main coronary artery from the left coronary sinus. There was a single right coronary artery (RCA) with a super dominant course from right coronary sinus. It also showed a left main coronary and left anterior descending artery arising separately from proximal RCA, with retroaortic and prepulmonic course, respectively. There was another independently arising small septal branch from the proximal RCA that supplied the proximal interventricular septum. The patient was managed with optimal medical therapy and had symptomatic relief.

Complications resulting from the delayed clinical presentation of a left main coronary artery obstruction can be catastrophic. This case report presents a 73-year-old woman with severe aortic stenosis who underwent transcatheter aortic valve replacement with a core valve who, approximately 20 minutes after heparin reversal with protamine, became hypotensive and was unresponsive to vasopressor and inotropic therapy. Transesophageal echocardiography demonstrated global hypokinesis, which was highly consistent with the occlusion of the left main coronary artery. Angiography confirmed this diagnosis and demonstrated that valve positioning had not changed compared to post-placement examination. Here we report the partial covering of the ostium of the left main coronary artery by a core valve skirt that converted into a total occlusion following the initiation of heparin reversal with protamine and the value of multimodal imaging in the management of this case.
