Key result
Surgical treatment of atrioventricular canal defects is linked to ~35% mortality in complete cases.
Why the study?
Outcomes after surgical treatment of congenital atrioventricular canal defects require detailed description to inform clinical management.

What are the clinical outcomes and mortality rates following surgical treatment in patients with atrioventricular canal defects?
Surgical treatment of atrioventricular canal defects is associated with higher mortality in complete defects compared to partial defects, though survivors generally have good functional outcomes without persistent AV block.
Robert L. Hardesty (1975) conducted an observational in Congenital anomalies of the atrioventricular canal (n=59). Surgical treatment was evaluated on Postoperative mortality. Surgical treatment of atrioventricular canal defects in 59 patients resulted in a 7.1% mortality rate for partial defects and 6 deaths among 17 patients with complete defects.
