title: Pulmonary atresia with intact ventricular septum: long-term results of "one and a half ventricular repair".
abstract: BACKGROUND
  Between 1982 and 1984, we successfully performed "one and a half ventricular repair" using a Glenn shunt for 3 patients with pulmonary atresia with intact ventricular septum. Here we review the 10-year follow-up results.
  
  
  METHODS
  In these patients, the preoperative Z scores of the tricuspid valve diameters ranged from -5.2 to -6.5. Right ventricular outflow tract reconstruction combined with a Glenn shunt were performed in all patients. Cardiac catheterization was done at least 10 years post-operatively.
  
  
  RESULTS
  All 3 patients have maintained New York Heart Association functional class I status for more than 10 years. Angiography in 2 patients confirms sufficient left pulmonary artery pressure with pulsatile blood flow and good right ventricular contraction. A pulmonary arteriovenous fistula has developed in 1 patient.
  
  
  CONCLUSIONS
  Although the lower limits of the tricuspid valve diameter for "one and a half ventricular repair" using a cavopulmonary shunt have not yet been determined, we successfully performed this procedure in 3 patients with severely hypoplastic right ventricles and tricuspid valve diameter Z scores of less than -5.0. The results up to 10 years postoperatively are acceptable.
