Why the study?
Some patients develop narrowing of their extracardiac Fontan conduit that rarely requires surgical replacement, prompting the presentation of an alternative surgical technique in a patient with dextrocardia.
Off-pump surgical creation of an alternate extracardiac Fontan conduit pathway is a feasible and safe solution for patients with obstructed, calcified conduits and dextrocardia, avoiding the risks of cardiopulmonary bypass.
Transcatheter management of Fontan conduit narrowing remains hypothesis-generating; leaves open optimal strategies and durability in univentricular patients.
2023 in Elite World Convention Center in stanbul, Turkey.The extracardiac Fontan procedure is the final common pathway for palliation of patients with univentricular physiology.The procedure is typically performed on cardiopulmonary bypass with or without fenestration using an adequate-sized polytetrafluoroethylene graft as the extracardiac conduit.On a few occasions, some patients may develop narrowing of their conduit with or without calcifications, which is often managed by various transcatheter techniques.Rarely, some of these conduits must be replaced surgically.In the current report, we present an alternative to standard surgical replacement of the calcified Fontan conduit in a patient with dextrocardia.
