We report on an acute myocardial injury caused by thrombotic emboli during off-pump bilateral sequential lung transplantation in a 15-year-old female patient with end-stage cystic fibrosis. A few minutes after reperfusion of the right (second sequential) allograft, the patient developed hemodynamic collapse, including hypotension, acute akinesis of the anterior and lateral myocardial walls, and severe mitral regurgitation. Thrombus was noted within the left atrium and ventricle on intraoperative transesophageal echocardiogram. After emergent cannulation for cardiopulmonary bypass, the patient underwent left cardiac catheterization with AngioJet rheolytic thrombectomy and removal of the clot from the distal left anterior descending coronary artery. Reperfusion was established without the need for stent placement or further intervention. The patient required short-term life support with venoarterial extracorporeal membrane oxygenation. © 2012 The Society of Thoracic Surgeons.
