A Rare Case of Early Left Ventricular Thrombus Development After Off-Pump Coronary Artery Bypass Grafting for Unstable Angina Pectoris With Reduced Left Ventricular Ejection Fraction.

Left ventricular (LV) thrombus is a serious complication of myocardial infarction (MI) that can lead to a fetal systemic embolism. Although coronary artery bypass graft surgery (CABG) after MI is widely performed, to our knowledge, there are no reports of LV thrombus in the early postoperative period. Here, we report a rare case of a 70-year-old man who underwent off-pump coronary artery bypass grafting (OPCAB) for unstable angina pectoris with reduced left ventricular ejection fraction (LVEF).
