Rewriting the 10 Commandments: Fontan Candidacy in the Modern Era.
Single ventricle congenital heart disease (SVCHD) remains a high-risk pathology for transplantation-free survival and quality of life. While medical and surgical advancements have significantly improved attrition through palliation and ultimately survival following the Fontan operation, Fontan candidacy evaluation remains a critical component to insuring optimal outcomes for patients with SVCHD. While the initial 10 Commandments proposed by Choussat and colleagues provided pioneering insights and supported early success of the Fontan operation, advancements in care have shifted the focus of Fontan candidacy determination to be patient- and center-specific, seeking to maintain both Fontan and transplantation candidacy across all risk categories. Herein, we present a focused review of the current state of Fontan candidacy determination while also offering a multidisciplinary perspective within this evolving and nuanced aspect of care for patients with SVCHD.
