ABSTRACT
AIM: This study compared outcomes following the double-patch and Warden procedures for correcting partial anomalous connection of the right pulmonary veins to the superior vena cava. METHODS: Eighty (80) patients, aged <18years old, and with partial anomalous connection of the right pulmonary veins to the superior vena cava were randomly assigned into double-patch method (n=40) and Warden procedure (n=40) groups. The median follow-up was 22.5 (range, 12-39) months. The primary endpoint was sinus node dysfunction at the mid-term follow-up period. RESULTS: No early or late mortality occurred. In the early postoperative period, sinus node dysfunction was observed in 27.5% and 5% of cases after double-patch correction and the Warden procedure, respectively (risk ratio, 5.50; 95% confidence interval, 1.30-23.25; p=0.01). At follow-up, sinus node dysfunction persisted in two (5%) patients after double-patch correction. All patients had normal sinus rhythm after the Warden procedure. No early or late pacemaker implantation occurred in either group. No patients had significant pulmonary veins or superior vena cava stenosis. CONCLUSIONS: The double-patch technique and Warden procedure both showed excellent early and mid-term results with no mortality and minimal morbidity. The Warden procedure was associated with less sinus node dysfunction in the early postoperative period than the double-patch technique. There was no significant between-group difference in sinus node dysfunction at the mid-term follow-up.

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.

We describe a new technique of perventricular closure of a perimembranous ventricular septal defect on a beating heart using transesophageal echocardiography guidance and video-assisted thoracoscopy. Ventricular septal defects were closed successfully, and no shunts, rhythm disorders, or valve incompetence developed during the short hospital stay. This procedure is safe and effective for selected patients. These early and mid-term results encourage further evaluation.
