Pak J Cardiol Jan ;13(3-4):59-64.

The objective of this study was to investigate the effects of Transmyocardial Revascularization by Laser (TMRL) in patients of ischemic heart disease. 50 patients of ischemic heart disease NYHA class III, IV who were not suitable for other methods of revascularization like CABG, PTCA (`No Option` patients) were offered TMRL. These patients were symptomatic on maximum medical treatment. 50 patients of angina NYHA class III, IV (mean 3.44 ± 0.50) were offered TMRL. Their angina class improved to mean 1.88 ± 0.74 at 6 month (p=0.00585) and persisted at mean 0.96 ± 0.77 at 2 years (p =0 0.0150). Their ETT mean value before operation was 5.036 ± 1.54 minutes and at 2 years mean was 6.56 +/- 1.79 minutes (p=0.8318). Kaplan Meier symptoms free survival rate was 83.1% at 6 months (14 censored) and 77.3 at 2 years (24 censored).
