TI  - Atrioventricular canal defects: results of repair in the current era.
PG  - 367-72
AB  - Between December 1986 and December 1990, 37 consecutive patients underwent repair 
      of complete atrioventricular (AV) canal with the two-patch technique. Mean age at 
      repair was 22 months and 51% were less than 1 year of age. Eighteen (48.6%) had 
      undergone previous palliative operations. Two operative deaths (5.4%) occurred 
      and another patient died in-hospital for an early mortality of 8.1%. One late 
      death (2.9%) has occurred from a respiratory infection. Actuarial survival is 
      87.7% at 3 years. Small size (p less than 0.05), unbalanced ventricular size (p 
      less than 0.05), New York Heart Association (NYHA) Class IV (p less than 0.05), 
      and severe preoperative AV valve insufficiency (p less than 0.05) were 
      significant preoperative risk factors for death. Five survivors (14.7%) required 
      reoperation for severe AV valve insufficiency (two) or patch leaks (three). The 
      risk for reoperation was increased in non-Down's patients (p less than 0.02). All 
      survivors are in NYHA Class I (93%) or II (7%). The risk for early AV valve 
      insufficiency was increased in patients who did not have the cleft sutured (p 
      less than 0.05), and in those with unbalanced ventricles (p less than 0.01). Risk 
      of late AV valve insufficiency was increased only by small size (p less than 
      0.02). Previous pulmonary artery banding did not increase the risk of repair or 
      of postoperative AV valve insufficiency. Complete AV canal can be repaired with 
      low mortality. Pulmonary artery banding may still have a role to play in the very 
      small (4-5 kg) infant in refractory heart failure.
