Key result
Novel surgical technique successfully repairs unusual complete AV canal defect without residual septal defects.
Why the study?
Unusual anatomical variants of congenital heart defects present opportunities to innovate surgical approaches beyond standard single-patch, double-patch, or modified single-patch techniques.

This case report describes a novel surgical approach for repairing an unusual variant of complete atrioventricular canal defect.
May inform repair of rare complete AV canal variants; leaves open generalizability without larger series.
Background Complete atrioventricular canal is a congenital heart defect that is characterized by an atrial septal defect, ventricular septal defect, and a common atrioventricular valve. Standard surgical techniques for repairing complete atrioventricular canal defect mainly includes repairing the defect with a single patch, a double patch, or with the modified single patch technique. Case presentation This paper presents a novel surgical repair technique of an unusual anatomical presentation for a complete atrioventricular canal defect in a patient with Down syndrome. Conclusions Unusual anatomical variant for congenital heart defects occurs frequently, which gives surgeons real opportunities to innovate surgical approaches. This patient was an example of an unusual anatomical presentation for complete atrioventricular canal, and the surgical technique used for this patient was novel. Follow up for these patients is mandatory for long term results.

Qabha et al. (2021) conducted a case report in Complete atrioventricular canal defect (n=1). Novel surgical repair technique was evaluated on Postoperative echocardiogram findings and clinical recovery. A novel surgical repair technique successfully treated a 5-month-old girl with an unusual variant of complete atrioventricular canal defect, resulting in no residual septal defects and trivial AV valve regurgitation.
