Transmyocardial laser revascularization
Transmyocardial laser revascularization (TMLR) is a procedure used to treat severe coronary artery disease when other methods aren't effective. It involves using a laser to create small channels in the heart muscle, which can help improve blood flow. The laser creates these tiny openings from the outer surface of the heart into the muscle, allowing blood to reach areas that are blocked or narrowed by artery disease. This procedure can help reduce chest pain and improve heart function by promoting new blood vessel growth and increasing oxygen supply to the heart tissue.
