Total correction of complete atrioventricular canal: surgical technique and analysis of long-term results

Surgery for total correction of complete AVC can be done with low early and late mortality. The operative risk is high only in patients who reach the operating room in a near moribund condition (NYHA V). There is clinical evidence that early operation - before the onset of pulmonary vascular disease - will further lower early and late mortality. The surgical technique has been refined to avoid late reoperation for left atrioventricular valve incompetence. The early and late results of operative therapy compare favourably with the natural history of this complex congenital cardiac disease.
