Schematic of surgical approach via median sternotomy utilizing aortic and bicaval cannulation for cardiopulmonary bypass: SVC transection allowing for heart rotation and exposure and en bloc excision of tumor and posterior left atrium (dotted line represents resection plane). Subsequently, the posterior left atrium was reconstructed with de-cellularized bovine pericardium sewn into the pulmonary venous ostia. Additional surgical detail highlighted in Supplementary Movie 1. IVC, inferior vena cava, SVC, superior vena cava
