Key result
Modified single-patch AVSD repair simplifies teaching vs two-patch, driven by shorter clamp and bypass times.
Why the study?
Understanding atrioventricular septal defect morphology and mastering operative strategies for repair is challenging for congenital cardiac surgery residents.
The modified single-patch technique is an excellent and relatively easy strategy to teach congenital cardiac surgery residents for repairing complete atrioventricular septal defects.
Modified single-patch technique may aid resident training in AVSD repair; leaves open whether outcomes match two-patch technique.
Understanding the morphology of atrioventricular septal defects and learning the operative strategies for their repair is one of the more difficult tasks for congenital cardiac surgery residents to master. The modified single-patch technique for several reasons lends itself to being a strategy that is relatively easy to teach residents. It has shorter cross-clamp and bypass times than the standard two-patch technique, which allows more time for the instructor to safely take the resident through the case. The steps of the operation are quite standard and broadly applicable to the wide variety of cardiac morphologies found in children with atrioventricular septal defects. The purpose of this review is to carefully point out the technical details of each step of the modified single-patch technique focusing on teaching the resident surgeon. The ease of teaching this excellent technique is just another reason to use the modified single-patch technique.

Stephens et al. (2022) conducted a review in Complete atrioventricular septal defect. Modified single-patch technique vs. Standard two-patch technique was evaluated. The modified single-patch technique for complete atrioventricular septal defect repair is relatively easy to teach to residents due to shorter cross-clamp and bypass times than the standard two-patch technique.
