Consensus expert recommendations for the diagnosis and management of autosomal recessive polycystic kidney disease: report of an international conference.

Autosomal recessive polycystic kidney disease (ARPKD; MIM 263200) is a severe, typically early onset form of cystic disease that primarily involves the kidneys and biliary tract. Phenotypic expression and age at presentation can be quite variable. The incidence of ARPKD is 1 in 20,000 live births, and its pleotropic manifestations are potentially life-threatening.

Pulmonary valve cusp augmentation with autologous pericardium may improve early outcome for tetralogy of Fallot.

Objectives: The transannular patch used to relieve right ventricular outflow tract obstruction in children with tetralogy of Fallot may result in pulmonary insufficiency. We hypothesized that pulmonary valve cusp augmentation with pericardium would decrease pulmonary insufficiency and improve the early outcome for transatrial-transpulmonary tetralogy of Fallot repair requiring transannular patch.

Methods: Since November 2001, 41 patients with tetralogy of Fallot and 2 patients with isolated pulmonary valve stenosis had relief of right ventricular outflow tract obstruction with either a transannular patch plus pulmonary valve cusp augmentation (n = 18) or a transannular patch alone (n = 25).
