| Popis: | Intercoronary communication or coronary arcade is a rare congenital abnormality. The authors report the case of a patient with intercoronary communication, chest pain, and electrocardiogram showing an early ventricular repolarization pattern, but no significant atherosclerosis at the coronary angiography. Nevertheless, an intercoronary communication with unidirectional flow between the right coronary artery and the left circumflex artery was visualized, and later assessed by physical stress echocardiography, which did not detect ischemia. Although intercoronary communication is usually unrelated to ischemia, there are reports in the literature that unidirectional flow can cause myocardial ischemia through coronary steal. |
