Lasers, Ho:YAG, Percutaneous Myocardial Revascularization

Definition : Holmium:yttrium aluminum garnet (Ho:YAG) pulsed lasers designed to deliver their energy into the myocardium using fiberoptic catheters (typically a few millimeters deep but not through all the cardiac muscle), producing temporary myocardial channels. These lasers may induce mechanisms of revascularization (e.g., myocardial angiogenesis), other mechanisms (e.g., myocardial denervation, myocardial fibrosis), and/or placebo effects. The laser delivery systems include fiberoptic catheters for percutaneous delivery (i.e., percutaneous myocardial revascularization) through the vasculature. Percutaneous revascularization lasers are intended for palliative treatment of stable angina; they may also improve blood perfusion to the myocardium.

Transmyocardial revascularization (TMR) is performed with a low powered Holmium:YAG laser that delivers precise laser energy directly to the target area(s) of the heart muscle. When performed as a sole therapy, it is done through a small incision between the ribs (thoracotomy) with the patient under general anesthesia. TMR can also be performed as a complement to bypass surgery in patients that have areas of ischemic heart disease that cannot be bypassed. The precise laser therapy is used to create small channels into the heart chamber which stimulate the heart muscle to create new blood vessels
