There are some problems in surgical treatment for those patients with small branches or diffuse stenotic lesions of the coronary arteries, for whom coronary artery bypass grafting can not be carried out at all. To resolve these problems, we have planned to supply arterial blood from the left ventricle into the ischemic myocardium through holes cut into the myocardium by laser. It was clearly recognized that arterial blood could be hemodynamically supplied from the left ventricle into the ischemic myocardium. In trials on dogs laser holes 0.2 mm in diameter have been shown microscopically to be patent even 3 years after their creation, thus this procedure could be used as a new method of myocardial revascularization. Consequently, myocardial revascularization by laser was employed in a 55-year-old male patient with severe angina pectoris who had undergone pericardiectomy 2 years before. He is doing well 5 years and 3 months after surgery.
对于那些冠状动脉小分支或弥漫性狭窄病变的患者，外科治疗存在一些问题，因为他们根本无法进行冠状动脉搭桥术。为了解决这些问题，我们计划通过激光在心肌上打孔，将左心室的动脉血供应到缺血心肌中。已经清楚地认识到，动脉血可以通过血流动力学从左心室供应到缺血心肌中。在对狗的试验中，直径0.2毫米的激光孔在显微镜下显示即使在打孔3年后仍保持通畅，因此该手术可作为一种新的心肌血运重建方法。因此，一名55岁的男性患者，两年前接受了心包切除术，患有严重心绞痛，采用了激光心肌血运重建术。术后5年零3个月，他情况良好。
