A 78-year-old woman with atrial fibrillation and heart failure with preserved ejection fraction presented with recurrent dyspnea and volume overload. A transthoracic echocardiogram demonstrated severe right ventricular enlargement and dysfunction. A CT pulmonary angiogram demonstrated partial anomalous pulmonary venous return and a transesophageal echocardiogram revealed a sinus venosus defect with left to right shunting. A right heart catheterization with oximetry saturation (“shunt run”) demonstrated pulmonary hypertension and a large left to right shunt (Qp/Qs ~ 3).
