Coronary Embolism From a Sinus Venosus ASD With PAPVD.

ABSTRACT:

Background

Paradoxical embolism (PDE) is a rare, underrecognized cause of acute coronary syndrome, occurring when a thrombus crosses an intracardiac defect into systemic circulation. Sinus venosus atrial septal defects (ASDs), often associated with partial anomalous pulmonary venous drainage, may manifest in adulthood with complications such as PDE.

Case summary

We describe a 52-year-old man presenting with non-ST elevation myocardial infarction. Coronary angiography showed a distal right coronary occlusion suggestive of embolic infarction. Transthoracic echocardiography with bubbles revealed a right-to-left shunt. Transesophageal echocardiography confirmed a sinus venosus ASD with partial anomalous pulmonary venous drainage. Surgical correction with intra-atrial baffle and
