Clinical outcome of patients 20 years after Fontan operation — effect of fenestration on late morbidity

Abstract

Long-term survival after Fontan procedure is encouraging, but late morbidity remains suboptimal. During follow-up, emerging complications should be managed by surgical and interventional procedures. Fenestration in Fontan circulation provided better cardiac output and lower incidence of late tachyarrhythmias, suggesting a benefit of fenestration for late outcome.
