Myocardial bridging is a congenital anomaly of the left anterior descending coronary artery (LAD), which is associated with myocardial ischemia and infarction, cardiac arrhythmias, and sudden cardiac death. Two cases are reported of symptomatic myocardial bridging refractory to medical management treated by minimally invasive coronary artery bypass grafting without cardiopulmonary bypass. We conclude that minimally invasive coronary artery bypass techniques are appropriate alternatives to endovascular stent placement, muscle bridge division, or aortocoronary grafting with cardiopulmonary bypass for the management of symptomatic myocardial bridging.
心肌桥是左前降支冠状动脉（LAD）的一种先天性异常，与心肌缺血和梗死、心律失常及心源性猝死相关。本文报道了2例经药物治疗无效的有症状心肌桥患者，采用非体外循环下微创冠状动脉搭桥术进行治疗。我们得出结论，对于有症状心肌桥的治疗，微创冠状动脉搭桥技术是血管内支架置入、肌桥切断或体外循环下主动脉冠状动脉搭桥术的合适替代方法。
