Protein losing enteropathy is one of the long term complications of grossly elevated systemic venous pressures which can occur following a Fontan surgery.
Persistent shunts after Fontan surgery Persistent shunts after a Fontan type of surgery can be due to various reasons like: Dehiscence of patches used for repair Dehiscence of
Bioresorbable vascular scaffolds or (bioabsorbable coronary stents) tend to restore the coronary configuration and systolo diastolic movements to those seen before implantation.
Partial fenestration of Fontan circuit leaving an ASD prevents rapid rise in venous pressure as it relieves excessive RA pressure in immediate postop period.
