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

<div>Two-dimensional transthoracic echocardiography in the apical four-chamber view. Panel (a) was obtained prior to surgical correction and demonstrates significant right atrial and ventricular enlargement. Panel (b) was obtained six months following surgical correction and demonstrates normalization of the right atrial and ventricular sizes. RA: right atrium; RV: right ventricle; LA: left atrium; LV: left ventricle.</div>
