Transmyocardial Laser Revascularization

Transmyocardial Laser Revascularization (TMLR) is a procedure used to increase blood flow to damaged heart tissue. In the procedure, the surgeon uses a special laser to make 20-30 small channels in the heart tissue. After the procedure, these channels provide increased blood flow and oxygenation to the damaged heart muscle, and may stimulate the growth of new blood vessels in the area.
TMLR is often completed in conjunction with coronary artery bypass grafting (CABG). As a standalone procedure, TMLR does not require a full sternectomy. Instead, a small incision is made in the rib cage, and the procedure is completed through this entry point. This benefits the patient by reduced recovery time and reduced pain when compared to a full sternectomy.
