A 50-year-old man presented to emergency department with chest pain for 1 h. Electrocardiogram noted an ST-segment elevation in the inferior leads (A), which resolved completely 15 min later when the patient's symptoms subsided (B). Coronary angiogram revealed a total occluded proximal right coronary artery (RCA) and a critical stenosis of middle left anterior descending artery (LAD) with a collateral flow to the distal RCA (C, white arrows, Online Video 1). Primary percutaneous coronary intervention was performed to the RCA successfully with an antegrade collateral flow to the distal LAD (D, black arrow,Online Video 2). Pre-existing collateral channels may reverse when the feeding artery is compromised in ST-segment elevation myocardial infarction with a complete ST-segment elevation resolution and should not be delayed for emergency percutaneous coronary intervention (1).
