[Excellent late results of total circulatory annuloplasty with absorbable suture for the repair of mitral regurgitation of atrioventricular septal defects in children].

We treated 15 children with atrioventricular septal defects (6 complete type and 9 incomplete type) using total circulatory annuloplasty for mitral regurgitation. In 14 patients, total circulatory annuloplasty was performed with absorbable suture and in one patient with polypropylene suture. Operative death was one patient associated with tetralogy of Fallot and another 14 patients survived. Preoperative mitral regurgitation was grade 1 in one patient, grade 2 in 6 patients and grade 3 in 7 patients. After operation mitral regurgitation reduced to grade 1 in 13 patients and grade 2 in one patient. In the late results, only one patient underwent reoperation for exacerbation of mitral regurgitation. The present data suggested that total circulatory annuloplasty with absorbable suture was very useful technique for the repair of mitral regurgitation of atrioventricular septal defects in children.
