“…They concluded that LVOT obstruction is not a significant complication after modified single patch repair of AVSD. Previous operation for coarctation of aorta is an important predictor of late LVOT obstruction following modified single patch technique (33).…”

Atrioventricular septal defect (AVSD) is a common congenital cardiac surgical problem. Over the years, younger and smaller infants are having operations for this condition before irreversible cardio pulmonary changes occur. Traditionally a single or two patch techniques have been used to repair this defect. However, in the past two decades an innovative method of modified single patch technique popularized by Dr. Graham Nunn has gained worldwide popularity. This review discusses the origin, surgical principles, technique and outcomes of this method, popularly known as Nunn or Australian technique. Research comparing the modified single patch technique to classic single and double patch techniques has shown good preservation of atrioventricular valve function, no residual ventricular septal defect (VSDs), low incidence of left ventricular outflow obstruction, preserved conduction, easy reproducibility, and improved perioperative and long-term mortality.

“…This postoperative complication is more common in patients with partial AVSD than in those with complete AVSD [7]. We recently reviewed our experience with subaortic stenosis in patients undergoing repair of complete AVSD [8]. In a cohort of 77 patients, only 2 (2.5%) underwent reoperation for LVOTO.…”

“…4 Of critical importance our recent evaluation demonstrated that left ventricular outflow tract obstruction does not appear to be a significant postoperative issue with the modified single-patch repair. 5 The following illustrations demonstrate use of the no VSD patch technique for complete AVSD in 2 different patients; 1 with Rastelli type "A" configuration of the AV valves and the other with Rastelli type "C" configuration of the AV valves. 6 At Ann & Robert H. Lurie Children's Hospital of Chicago we transitioned from using the 2-patch technique to now using almost exclusively the modified single-patch or "no VSD patch" technique (Figs.…”

For the past 10 years, our center has used the no ventricular septal defect patch atrioventricular septal defect repair proposed independently by Wilcox and Nicholson. The technique emphasizes direct closure of the ventricular element of the defect and a pericardial patch for the atrial component. A particular advantage of the operation is that it lends itself to repair in the smaller infant, which allows operative repair at 3-4 months of age, decreasing the risk of perioperative problems with pulmonary hypertension. The result of this strategy at multiple centers is a very low operative mortality, a low incidence of left atrioventricular valve reoperation, and an extremely low incidence of need for a pacemaker.
