Patients with severe angina pectoris, refractory to medical treatment, in which conventional revascularization (PTCA or bypass surgery) is not possible because they present advanced coronary artery disease with a poor distal bed, account for an important clinical problem due to an increasing incidence, combined with poor quality of life, an elevated risk of severe complications, repeated hospital admissions and high mortality rate. Laser transmyocardial revascularization provides a new therapeutic alternative for these patients. Although up to now there are only a few published series, with a small number of patients, the results obtained in the two ongoing multicentric studies in Europe and the United States (including more than 500 patients at present) are quite promising. It is a simple surgical procedure, but its associated mortality is not to be dismissed (in the beginning 12% and currently 5%), because patients are in an advanced evolutionary stage. In Spain this procedure has been available since April 1996 and the results have been encouraging. In our small series we have noted a significant symptomatic improvement and better quality of life.
