Arrhythmias And Thromboembolic Complications After The Extracardiac Fontan Operation

Abstract

The incidence of hemodynamically significant tachyarrhythmias appears to be reduced after the extracardiac Fontan operation. A significant percentage of patients have evidence of sinus node dysfunction, suggesting the presence of other surgical or nonsurgical factors responsible for this finding. Our incidence of thrombotic events is similar to previous reports with other Fontan modifications. It appears to be a reasonable option to maintain these patients on anticoagulation indefinitely.

Surgical Management of an Extracardiac Total Cavopulmonary Connection in Heterotaxy Syndrome with Isolated Hepatic Drainage

“…In patients with heterotaxy syndrome, morbidity in terms of early postoperative pleural effusions and both early and late arrhythmia, is still significant and higher than in Fontan patients with other underlying malformations [8,9]. However, it has not been associated with increased mortality thus far [3,4].…”

The Adult With a Fontan: A Panacea Without a Cure?

“…31 Bradyarrhythmias have also been observed in patients undergoing the EC technique. 32 By far, the most common arrhythmia is intraatrial re-entrant tachycardia (IART), which is thought to be caused by postoperative atrial scarring. 33, 34 Atrial fibrillation is a less common complication and more often associated with the LA.…”

Entwicklung der Fontan-Prozedur als Behandlungskonzept für Kinder mit angeborenen komplexen Herzfehlern

“…Wegen des besseren laminaren Flusses innerhalb eines extrakardialen Conduits sowie durch Verzicht auf Fremdmaterial im Vorhof vermindert sich die Gefahr einer Thrombenbildung [30,44,51,69]. Dennoch führt die Implantation von Fremdmaterial in der Blutbahn zu einer Stauung im venösen System, und Störungen des Gerinnungssystems prädisponie-ren besonders Patienten mit Einkammerherzphysiologie zu thromboembolischen Komplikationen [6,14,47,58].…”
