[Myocardial revascularization using the internal thoracic artery: pro and con].
Internal thoracic artery (ITA) has superior histological, physiological and pharmacological properties over the venous grafts, and it is considered to be the graft of choice for myocardial revascularization. It has low incidence of late atherosclerotic lesions, and excellent long-term patency. Usage of ITA yields improved clinical results in all subgroups of patients with coronary artery disease, including patients with poor left ventricular function (EF%), left main stenosis, diffuse coronary artery disease and octogenarians. Since superior long-term results (to be expected only 10-15 years after the operation) may be outweighed with slightly higher incidence of early morbidity and mortality, many cardiac surgeons are reluctant to use it routinely. However, this attitude is difficult to justify, since early operative results in patients that have received ITA graft are superior as well, compared to patients that have received vein grafts only.
