Partial anomalous pulmonary venous return (PAPVR) associated with a sinus venosus atrial septal defect (SVASD) and a persistent left superior vena cava (PLSVC) presents significant surgical challenges. These anomalies require careful planning of cardiopulmonary bypass (CPB) and venous cannulation strategies. A 38-year-old woman presented with a history of supraventricular tachycardia (SVT) and a hemodynamically significant left-to-right shunt (Qp : Qs = 1.87) due to SVASD and PAPVR. Preoperative imaging revealed drainage of the right upper pulmonary vein into the PLSVC. The patient underwent successful surgical cor- rection using the double-patch technique with cardiopulmonary bypass support via a complex cannulation strategy involving both superior venae cavae. Postoperatively, the patient recovered well, with no evidence of residual shunt or significant valvular dysfunction. The case highlights the surgical approach to a rare combination of anomalies and discusses alternative cannulation strategies for CPB in patients with PLSVC.
