Catheters, Cardiac, Laser Percutaneous Myocardial Revascularization

Definition : Cardiac catheters designed for fiberoptic delivery of laser energy to the myocardium using percutaneous procedures, producing temporary myocardial channels. These devices typically consist of single-use, 6 Fr diameter, 125 cm (49 inch) length fiberoptic catheters with a 9 Fr sheath. Laser energy may induce real mechanisms of revascularization (e.g., myocardial angiogenesis), other mechanisms (e.g., myocardial denervation, myocardial fibrosis), and/or placebo effects. Percutaneous revascularization catheters 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
