Laser myocardial revascularization

Laser myocardial revascularization (LMR) is a new revascularization technique to overcome and compensate for the current ischemic heart surgery and interventional therapy. There are two types of epicardial irradiation and periosteum irradiation. The surgical method was applied to the clinic in 1988. It mainly uses laser to make ducts that penetrate or do not penetrate the ventricular wall from the epicardium to the endocardium or from the periosteum to the epicardium. These ducts are connected to myocardial sinusoids, Thebesian veins and arterial-cardiac blood vessels Anastomosis constitutes a new blood supply system, so that the oxygenated blood in the ventricle can be introduced into the ischemia from the heart cavity during systole, that is, the blood is directly supplied from the heart cavity, thereby improving the blood supply to the heart muscle.
