A Rare Potential Cause of Extraluminal Left Main Compression in ASD: An Echocardiographic Illustration

While atrial septal defect (ASD) classifies as the most common cause of grown-up congenital heart (GUCH) disease, it can present with unconventional symptoms, owing to the underlying pathophysiological alterations.1Atypical chest pain in ASD can be due to arrhythmias, right ventricular dysfunction, or ischemia. However, we describe an interesting echocardiographic finding, showcasing a rare potential cause of left main coronary artery (LMCA), resulting in chest pain in patients with ASD.
