This is the first study that assesses by cardiac catheterization and CPET the effects of ERA in patients with Fontan circulation with increased PVR. These results suggest that ERAs might provide most pronounced hemodynamic and functional improvement in adults and adolescents.

The new device ADO II AS was safely deployed with complete resolution of the PDA shunt. The lower profile and symmetry of this device allows for venous or arterial approach and smaller delivery catheter size. The ADO II AS might be a preferable alternative for closure of small-moderate PDAs.

Interventional catheterisation of stenotic or occluded systemic veins grants good immediate results at a low rate of complication. Stent dilatation or recanalisation may open the vessel for use during future procedures. However, long-term results are yet to be established.

The 22q11.2 microdeletion syndrome (22q11.2 DGS) is characterized by an extreme intrafamilial and interfamilial variability. The main clinical features are congenital heart defects, palatal abnormalities, learning disability, facial dysmorphisms and immune deficiency. In 85-90% of cases, the 22q11.2 DGS is caused by a heterozygous *3-Mb deletion, including the TBX1 gene, considered one of the major genes responsible for heart defects. Individuals with atypical deletions with at least one breakpoint outside low copy repeats have been reported. Our patient is a child presenting tetralogy of Fallot (TOF) with an atypical 22q11.2 deletion proximal to the critical DiGeorge region. The rearrangement was inherited from the healthy mother and spanned *642-970 kb, encompassing DGCR6 and PRODH, two novel possible candidate genes for conotruncal heart defects.
