Transmyocardial Laser Revascularization

What is Transmyocardial Laser Revascularization (TMLR)?

Transmyocardial laser revascularization is a procedure used to increase blood flow to damaged heart tissue.  These channels are believed to stimulate the growth of new blood vessels in the area and provide increased blood flow to the damaged heart muscle.

How is Transmyocardial Laser Revascularization Performed?

TMLR is often completed in conjunction with coronary artery bypass grafting (CABG).  As a standalone procedure, TMLR may be performed using minimally invasive heart surgery techniques that do not require a full sternotomy (opening of the breastbone).  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 sternotomy.

During the procedure, the heart surgeon uses a special laser to make 20-30 small channels in the heart tissue.  The surgical incision is then closed with sutures, and the patient returns to the recovery room.  The procedure typically takes 1 to 2 hours to complete.
