Diagnostic and Procedural Challenges of a Prominent Eustachian Valve During Transcatheter Closure of Atrial Septal Defect: A Case Report

A prominent Eustachian valve (EV) can mimic atrial septal structures or interfere with transcatheter closure of an atrial septal defect (ASD). We present a case where a large EV created diagnostic confusion and technical difficulties during device placement for ASD closure. Awareness of this anatomic variant is crucial to avoid misinterpretation and procedural complications.
