Early Correction of Common Atrioventricular Septal Defects: A Single-Center 20-Year Experience
A single institution experience during 22 years for early repair of complete AV canal defects (CAVCD) is reported. Repair was performed in 159 pts between 8 and 12 weeks of age. Operative mortality was 1.9% and later mortality was 7.7%. 13% required reoperation during long-term follow-up, primarily for left AV valve regurgitation. Left AV valve performance at last follow-up was significantly worse in pts older than 3 mons when repaired.
