Transmyocardial revascularization: a case study
Article Abstract:
A case study related to transmyocardial revascularization (TMR), an investigational cardiovascular surgical procedure for patients with severe advanced coronary artery disease refractory to conventional treatment, has been undertaken. The subject was a 67-year-old white male who had recurring refractory Canadian angina classification (CAC)IV angina with exertion and at rest. He had had a 3-vessel coronary artery bypass graft twice. At a 3-month postop visit, compared with 2 minutes and 1.6 METS preoperatively, he completed 8 minutes of an exercise protocol with elevation of 10% at speed of 1.7 mph and 5 METS.

Transmyocardial revascularization surgery
Article Abstract:
Transmyocardial revascularization surgery (TMR) may provide a therapeutic alternative for patients with angina who are not candidates for coronary artery bypass surgery or angioplasty. An investigational procedure, TMR uses a high-powered laser to create 20-35 tiny channels through the heart muscle into the left ventricle, potentially improving the supply of oxygenated blood to the myocardium. It is not yet clear whether these channels remain open, and whether the channels improve myocardial oxygenation. Three to six months may be required before patients obtain a clinical improvement.

Transmyocardial laser revascularization: old theory, new technology
Article Abstract:
Transmyocardial laser revascularization offers an alternative for patients with intractable angina. It involves an old theory, that of blood flow directly from the left ventricular chamber into the myocardium, but new technology, that of lasers. Laser technology gives a way to explore the possibility of revascularization through channels created in the left ventricle. Early studies show better relief of angina symptoms in patients who are not candidates for traditional medical/surgical revascularization methods.
