Key result
Transcatheter interventions treat Fontan circuit failure by alleviating obstructions, improving cyanosis, and increasing cardiac output.
Why the study?
The Fontan circuit often leads to circuit failure, the management of which is complex and requires multiple therapeutic options.
Transcatheter interventions have emerged as a key therapeutic option for managing various aspects of Fontan circuit failure in adults, improving hemodynamics and patient stabilization.
May inform transcatheter use in Fontan failure; leaves open need for prospective trials on outcomes and selection.
The Fontan circuit is associated with chronically elevated systemic venous pressures and decreased cardiac output, often leading to circuit failure. Managing Fontan circuit failure is complex and requires multiple therapeutic options. Transcatheter interventions have emerged as a reliable approach. They can alleviate obstructions and improve cyanosis by enhancing pulmonary blood flow and oxygen saturation. These procedures can also increase cardiac output and reduce systemic venous pressure, contributing to patient stabilization. In addition, they help mitigate volume overload and decrease the risk of bleeding during heart or combined heart and liver transplants. In recent years, percutaneous interventions have rapidly evolved and become a key therapeutic option for addressing various aspects of Fontan circuit failure. These interventions should be considered integral to the management strategy for this specific patient population.

Flores‐Umanzor et al. (2024) conducted a review in Fontan circuit failure. Transcatheter interventions was evaluated. Transcatheter interventions have emerged as a key therapeutic option for managing Fontan circuit failure by alleviating obstructions, improving cyanosis, and increasing cardiac output.
