Abstract: Objective To clarify the efficacy and safety of Warden series operation in partial anomalous pulmonary venous connection (PAPVC). Methods Six patients with PAPVC (pulmonary vein drainage to superior vena cava), who were treated in cardiac surgery of Tianjin Chest Hospital from January 2016 to March 2018, were included in this study. All 6 patients underwent Warden series operation, including 3 with Warden surgery and another 3 with modified Warden surgery. Two patients underwent modified Warden surgery were rebuilt by autologous pericardial patch and 1 cases were connected to the superior vena cava and the right atrium with Gor-Tax vessels. The echocardiography and electrocardiogram were reviewed regularly after operation (1 month, 3 months, 6 months and 1 year after operation，1 time a year for more than 1 year after the operation). The changes of cardiac structure, superior vena cava and pulmonary venous reflux and arrhythmia were observed. Results All patients were discharged successfully. The patients were followed up for 3 months to 2 years. No residual anomalous shunt was found in reexaminating echocardiography, and superior vena cava and pulmonary venous return were unobstructed. Electrocardiogram showed sinus rhythm and no obvious abnormality. Conclusion The application of Warden series operation in partial anomalous pulmonary venous connection is safe and effective.
