Key result
Stenting narrowed extracardiac Fontan conduits safely provides short-term benefits even without a resting pressure gradient.
Why the study?
Extracardiac Fontan conduits often narrow over time, and understanding of patient selection criteria and procedure timing for stent expansion is evolving.
Does stent expansion of narrowed extracardiac Fontan conduits provide clinical benefits?
Does stent expansion of narrowed extracardiac Fontan conduits provide clinical benefits?
Stenting of narrowed extracardiac Fontan conduits is safe and offers short-term benefits, highlighting its potential utility even without a resting pressure gradient.
May support stenting narrowed Fontan conduits without gradient; leaves open prospective trials for long-term outcomes.
Key Points Extracardiac Fontan conduits often narrow over time and can be returned safely to nominal diameter and larger with stents. Conduit expansion often produces short term benefits. Long‐term benefits seem likely but data are limited. A conduit pressure gradient at rest is often absent and is not required to identify potential benefit. Understanding of patient selection criteria and procedure timing is evolving.

Victor Lucas (2022) conducted a review in Extracardiac Fontan conduit narrowing. Stent expansion was evaluated. Stent expansion of narrowed extracardiac Fontan conduits safely restores nominal diameter and produces short-term benefits, even in the absence of a resting pressure gradient.
