Secondary transmyocardial laser revascularization in the treatment of end-stage coronary artery disease.

Transmyocardial laser revascularization (TMR) has received more acceptance within the last few years. The vast majority of TMR users report impressive clinical benefits. The underlying mechanism for benefit by TMR, however, remains somewhat unclear. Between July 1994 and September 1997, 165 patients underwent TMR at our institution. In three of our TMR patients after an initial angina-free interval of 1 to 2 years we decided to repeat the laser operation. This article focuses on the three re-TMR patients who underwent a second TMR operation 12 to 14 months after the first one. Two of the three patients are well and experience significantly less angina than preoperatively.
