Key result
Undetected large atrial septal defect causes paradoxical coronary embolism and inferior STEMI in young adult.
Why the study?
Chest pain in young adults is rarely caused by cardiac etiologies, and rare cases of myocardial infarction due to paradoxical coronary artery embolism require thorough evaluation.
Case Report (n=1)
This case highlights the importance of evaluating for structural anomalies like atrial septal defects in young adults presenting with myocardial infarction due to paradoxical embolism.
Paradoxical embolism via ASD can cause STEMI in young adults; extends differential but leaves open screening or prevention strategies.
Chest pain visits to the Emergency Department among the young adult population are rarely caused by cardiac etiologies. This case focuses on a 19-year-old man who developed an inferior ST-segment elevation myocardial infarction as a result of a previously undetected large atrial septal defect. This cardiac anomaly facilitated the transport of a paradoxical embolism that occluded the right coronary artery. This rare case highlights the importance of a thorough evaluation to rule out cardiac-related chest pain in young adults, despite the low incidence in this population.

Kei et al. (2015) conducted a case report in Myocardial Infarction (n=1). Paradoxical coronary artery embolism was evaluated on Inferior ST-segment elevation myocardial infarction. A previously undetected large atrial septal defect facilitated a paradoxical coronary artery embolism resulting in an inferior ST-segment elevation myocardial infarction in a 19-year-old man.
