[Myocardial bridge compressing the anterior inter-ventricular artery. Apropos of a successfully operated case].

Report of the case of a 26-year-old male patient, presenting with left-sided thoracic pains combined with electrocardiographic changes. Coronary arteriography demonstrated the presence, during systole, of a long, semi-localized stenosis of the anterior interventricular artery. Operation consisted only in the section of the myocardial bridge enclosing the artery on 4 cm. The clinical and coronary arteriographic result was perfect. No report of a similar case could be found in the literature.
