Abstract
Double Right Coronary Artery (RCA) is one of the rarest congenital coronary anomalies. Although it can be regarded as a benign condition in the vast majority of cases, it has been associated with acute and life-threatening presentations, including inferior ST-segment elevation myocardial infarction (STEMI), cardiogenic shock and complete heart block, tachyarrhythmias, or even sudden death. However, the role of a double RCA in these conditions is yet to be clarified as more recent data prove no statistically significant association between prevalence of significant atherosclerosis in anomalous coronary arteries in comparison to normal coronary arteries. Here we present a case of inferior STEMI in the context of double RCA, in which one of the two component branches was accidentally found after an “unexpected” jump of the coronary guidewire to treat what was initially considered the main vessel.
