摘要

Acute aortic root thrombosis extended to coronary ostia is a rare but potentially life-threatening complication of aortic valve replacement with bioprosthetic substitutes. We aimed to present the case of a 72-year-old woman with symptomatic rheumatic valve disease and associated atrial fibrillation who underwent conventional mitroaortic valve replacement with two stented bioprostheses (pericardial and porcine, respectively). Eight days after surgery, she had cardiac arrest due to ventricular fibrillation, requiring immediate cardiopulmonary resuscitation. Left ventricle akinesia by echocardiography and troponin levels up to 35,000 ng/L pointed to coronary ischemia. Emergent coronary angiography showed a subocclusion of the left main trunk, with the suspicion of aortic root thrombosis. The patient was immediately reoperated, fresh thrombi were removed from the aortic root, and the aortic Magna Ease 21-mm bioprosthesis was replaced with a stentless Solo Smart 21-mm bioprosthesis. The patient died of septic complications. (C) 2019 Elsevier Inc. All rights reserved.
