Open-Hybrid Aortic Stent Placement for Recurrent Coarctation in Complex Single Ventricles

TL;DR

A new open-hybrid surgical technique is introduced for treating aortic coarctation in patients with complex heart conditions, allowing for future stent expansion as the patient grows.

Contribution

The novel open-hybrid technique allows for stent placement that can be expanded later as the patient matures.

Findings

The technique limits arch dissection, reducing risks to the left recurrent laryngeal nerve.

Shorter anterograde cerebral perfusion time is achieved with this method.

Abstract

Recurrent coarctation of the aorta in patients with hypoplastic left heart syndrome requires timely intervention to limit ventricular dysfunction and atrioventricular valve regurgitation. Current strategies include catheter-based intervention in adequately sized patients or surgical arch augmentation at the time of a concomitant operation. We report an open-hybrid surgical technique with placement of a balloon-expandable stent that can later be expanded to an adult size as the patient grows. Limiting the arch dissection reduces the risk to the left recurrent laryngeal nerve and shortens anterograde cerebral perfusion time.
