Transmyocardial Laser Revascularization revisited.

Transmyocardial Revascularzation (TMR) is a relatively new surgical procedure used to treat angina that persists, despite other interventions (i.e. angioplasty, stenting or coronary artery bypass surgery). TMR is accomplished via an incision that exposes the heart muscle and permits application of the laser hand piece that creates new channels in the myocardium, thus improving myocardial perfusion and oxygen supply to the left ventricle. This article will explain the procedure, review patient selection criteria and discuss the nursing care for the TMR patient.
