Currently, minimally invasive cardiac surgery has found widespread use even in congenital heart surgery. The number of defects, which can be corrected through a small incision or totally endoscopic, is on the rise. Nowadays, surgeons can repair atrial septal defect, ventricular septal defect, patent ductus arteriosus and other congenital heart defects using minimally invasive techniques. In this paper, we report 21 cases of successful repair of supracardiac partial anomalous right upper and middle pulmonary venous connection, using the Warden procedure. It was performed in children through the right-sided midaxillary thoracotomy with direct cardiopulmonary bypass cannulation and induction of ventricular fibrillation. There were no operative or early postoperative deaths or complications. All patients were in sinus rhythm at discharge. According to echocardiography, there were no cases of early SVC or pulmonary veins narrowing. The Warden procedure can be performed safely and efficiently using the minimally invasive cardiac surgery.

Results of this meta-analysis reveal no difference in 6-year survival and reoperation rate for the left atrioventricular valve; however, patients who underwent staged repair had a higher rate of reintervention for the right ventricular outflow tract, which could be related to initially poor pulmonary bed anatomy. Therefore, both the primary repair and the staged repair are acceptable options for repair of complete atrioventricular septal defect with tetralogy of Fallot. The choice of surgical strategy must consider the anatomy of the pulmonary bed, patient condition and associated anomalies, which could affect surgical risk.
