Left main coronary artery occlusion after percutaneous aortic valve implantation.

Abstract

Left main coronary artery occlusion occurred immediately after transfemoral aortic valve implantation in an 87-year-old woman, which resulted in ventricular fibrillation and hemodynamic collapse. This life-threatening complication was promptly diagnosed with transesophageal echocardiography, which showed the disappearance of diastolic left main coronary artery jet flow and was confirmed with aortic root angiography. After prompt defibrillation, hemodynamic support was obtained with intra-aortic balloon pump and inotropic drugs. Functional recovery and survival were achieved with coronary stenting. This report highlights the importance of an integrated team approach of highly skilled specialists for these novel interventions.
