Closure of a lateral baffle leak in a Fontan patient with an Amplatzer PDA II AS plug

Abstract

Cyanosis after Fontan surgery or surgery for total cavopulmonary connection (TCPC), due to different types of communications (fenestration, venovenous collaterals or fistula), is not uncommon. We present the case of an 8-year-old girl presenting with increasing cyanosis during exercise 4 years after an intracardiac TCPC with lateral tunnel. Angiography showed a fistulous trajectory originating at the superior vena cava towards the base of the right atrial appendage. Due to the difficult anatomy in our patient, closure with conventional devices was not possible. We finally used a new Amplatzer PDA II AS plug to successfully close the fistula. In conclusion, closure of lateral baffle leak and device choice in case of difficult anatomy can be cumbersome. The new PDA II AS type plug can offer an elegant alternative for successful closure of some fistula
