Transmyocardial laser revascularization: old theory, new technology

Transmyocardial laser revascularization provides a promising alternative for patients with intractable angina. The concept of blood flow directly from the left ventricular chamber into the myocardium is not a new one, and recent studies have found the potential for this application in human hearts. Laser technology has provided an avenue for exploring the possibility of revascularization through channels created in the left ventricle. Early studies have demonstrated improved relief of angina symptoms in patients who are not candidates for traditional medical and surgical revascularization modalities.
