The mean follow up after surgical repair was 2.8 years, with no mortality or surgical reintervention. There was no conversion to median sternotomy, hemorrhage, pneumothorax, or diaphragm paralysis. However, complete heart block developed in 1 patient (1.5 years old, 9\u2005kg). Thirty patients underwent isolated left AV Valve cleft closure, and 4 patients underwent additional left AV valve annuloplasty. Preoperative echocardiogram showed moderate or more left AV valve regurgitation in 19\/32 patients (60%), which improved significantly after the surgical repair. Postoperative echocardiograms showed mild or less left AVvalve regurgitation in 31\/32 patients (97%) (\n                      <jats:italic toggle=\"yes\">P<\/jats:italic>\n                      \u2009&lt;\u2009.01).
