[Acute coronary syndromes with ST-segment elevation and anomalous connections of the coronary arteries].

Acute coronary syndrome with ST-segment elevation associated with an anomalous connection of a coronary artery, when the latter is the culprit, may be problematic. Anatomic and radiologic knowledge of major congenital coronary abnormalities and some catheterization skills can help the operators not to delay a beneficial coronary reperfusion. The relationship between acute coronary syndromes with ST-segment elevation and anomalous connections of the coronary arteries needs to be analyzed with a large number of cases because the coronary artery disease frequency may vary with the type of coronary anomaly.
