Transmyocardial laser revascularization.
Low-powered lasers were first used in the early 1980s to produce transventricular channels as an adjunct to coronary artery bypass graft surgery (CABG). Early results were encouraging, but because of the combined procedure, could not be attributed directly to use of the laser [1]. High-powered lasers were introduced into clinical practice in 1990 [2]. These lasers are powerful enough to create ...

BACKGROUND Indirect revascularization is a therapeutic approach in case of severe angina not suitable for percutaneous or surgical revascularization. Transmyocardial revascularization (TMR) is one of the techniques used for indirect revascularization and it allows to create transmyocardial channels by a laser energy bundle delivered on left ventricular epicardial surface. Benefits of the proced...

e s t e r d a y . The concept of what is now called transmyocardial revascularization actually precedes the evolution of coronary artery bypass (CABG) surgery and percutaneous transluminal coronary angioplasty (PTCA). Wearn described the myocardial microanatomy (most notably the arterioluminal sinusoids, which are poorly developed in humans but a major myocardial blood supply to reptiles) as ea...
متن کاملTransmyocardial revascularization devices: technology update
Transmyocardial laser revascularization (TMR) emerged as treatment modality for patients with diffuse coronary artery disease not amendable to percutaneous or surgical revascularization. The procedure entails the creation of laser channels within ischemic myocardium in an effort to better perfuse these areas. Currently, two laser devices are approved by the US Food and Drug Administration for T...
متن کاملPercutaneous laser revascularization does not equal transmyocardial laser revascularization.
We appreciate the suggestions of Dr. Veyrat regarding our study (1) and agree that it would be of interest to trigger the computed tomographic (CT) images at the time point of maximal aortic valve opening as previously calculated with Doppler velocity-time integral. However, some technical and logistic considerations arising from the CT perspective should be taken into account. The heart rate m...
