Successful Fontan conversion combined with cardiac resynchronization therapy for a case of failing Fontan circulation with ventricular dysfunction.

Although Fontan conversion combined with cardiac resynchronization therapy appears to be an effective surgical solution for the management of failing Fontan circulation with refractory atrial arrhythmia and cardiac dysfunction due to dyssynchronous ventricular wall motion, limited data are available on the mid- to long-term results of this treatment. We report our successful experience with Fontan conversion combined with cardiac resynchronization therapy in a male patient with failing Fontan circulation who showed favourable outcomes 5 years after the operation.
