transmyocardial revascularization

Laser heart surgery Cardiovascular surgery A technique used for Pts with incapacitating heart disease, in which 15 to 30 1-mm in diameter holes are 'drilled' by laser into the myocardium, in an operation that takes 60–90 mins; indications for TMR are similar to those for repeat CABGs–ie, severe heart disease Pros No need for heart-lung machine; lower costs–CABG is $15,000 to $20,000, recuperation is shorter Mortality ±8% Outcome 1 yr post-surgery, 90% of Pts have improved to NYHA class 1 to 2 angina Cf CABG.

transmyocardial revascularization

Abbreviation: TMR
The use of a laser to bore tiny channels directly through the wall of the heart in an attempt to bring oxygen-rich blood from the left ventricular cavity to areas where the heart muscle is oxygen-deprived, or ischemic. TMR is an alternative to coronary bypass surgery or angioplasty, esp. in patients with complex plaques that would be difficult to reach with standard interventions or in patients who have already undergone many other procedures without effect.
Synonym: percutaneous myocardial revascularization
