Background : The improved repair techniques that have resulted from the increased understanding of atrioventricular Valve anatomy and physiology , In 1999 Nicholson from Australia , described new technique for rapier at complete Av canal , we choice Australian technique in our study.

Methods: Between May 2008 and September 2008, 9 patients with complete atriventricular canal underwent monopatch procedure. All patients were operated on same technique, under hypothermic cardio pulmonary bypass and arrested with blood cardioplegia 4/1 and all patients have same ICU managements.

Results : mean age at surgery was 6/8 1/2 months , mean weight was .5.4 1 kg , trisory 21 was present in 7 patients Early survival was 86% , no patients had residual ventricular septel detect and 3 patients had mild mitral valve regurgitation and no patients had LV outflow obstruction and all patients had increased weight after two months.
Conclusions: mono-patch repair in complete atrioventricular canal is a safe and fast technique. Among survival in short time was good a but we need to evaluation in future.
