Sinus Venosus Atrial Septal Defect as a Cause of Palpitations and Dyspnea in an Adult: A Diagnostic Imaging Challenge

<div>Long axis cardiac magnetic resonance imaging prior to surgical correction. Panel (a) demonstrates severe right ventricular enlargement during end-diastole of the cardiac cycle. Panel (b) demonstrates severe right atrial enlargement during end-systole of the cardiac cycle. RA: right atrium; RV: right ventricle; LA: left atrium; LV: left ventricle.</div>
