Transmyocardial revascularization surgery.

Abstract

Transmyocardial revascularization (TMR) surgery is a palliative and investigative surgical procedure with the goal of increasing the quality of life for patients with intractable angina pectoris who are unsuitable for percutaneous transluminal coronary angioplasty or coronary artery bypass graft surgery. It improves myocardial perfusion and oxygen supply to the left ventricle, thus decreasing the frequency and intensity of anginal episodes. Many patients continue to have episodes of angina post-operatively but the frequency of those episodes should decrease. TMR may be a good treatment option for otherwise untreatable patients who live with severe, debilitating angina.
