Sinus venous defect is an uncommon type of atrial septal defect (ASD), often associated with anomalous pulmonary vein drainage and left to right shunting. If undetected, it leads to right atrial and ventricular volume overload. The current case describes an asymptomatic athlete with missed large sinus venosus defect since birth, and the different types of cardiac imaging modalities that lead to the detection of the defect and guiding the appropriate surgical intervention.
