Intermediate-term follow-up after transmyocardial laser revascularisation.
Transmyocardial laser revascularisation has emerged as a new therapeutic option for patients with severe diffuse coronary artery disease refractory to conventional modes of therapy. One hundred and two patients underwent isolated transmyocardial laser revascularisation between December 1994 and November 1997. After transmyocardial laser revascularisation, angina class improved from 2.56 +/- 0.8 to 0.8 +/- 0.9 by the end of one year and 54 percent patients were angina-free. Treadmill test workload increased from 3.6 +/- 1.7 METS pre-operatively to 6.0 +/- 3.4 METS (p < 0.005) at the end of one year's follow-up. However, left ventricle ejection fraction by MUGA slightly decreased (p = NS) at the end of one year. We conclude that transmyocardial laser revascularisation provides symptomatic benefit, improves quality of life and objectively improves the exercise tolerance at 12 months post-procedure.
