[Coronary circulation in abnormal left coronary artery arizing from the pulmonary artery trunk, before and after correction].
Two patients, both of them young girls, aged 14 and 15, had this condition and were studied by haemodynamic methods preoperatively and during the seventh postoperative month. In both cases, the retrograde perfusion of the left coronary vascular tree was shown up well, demonstrating the "coronary steal" and a left-right shunt of 2 volumes. In both cases also, the postoperative coronary arteriogram showed a return of the left coronary circulation to normal, disappearance of the large anastomatic vessels, and above all a return to normal dimensions of the right coronary artery, previously extremely tortuous and dilated. The 30 or so cases of total correction published in the world literature have been reviewed in the light of these two new cases.
