[Valvuloannuloplasty for atrioventricular valvular regurgitation in complicated cyanotic cardiac anomalies].
Valvuloannuloplasty for atrioventricular (AV) valvular regurgitation was performed in 13 patients with univentricular AV connection and double outlet right ventricle. The suturing-up of free margins of the anterior and posterior common leaflets, which divides the common orifice into two parts, was performed in 4 children with quadricuspid or quintacuspid common AV valve and effectively reduced the regurgitation. The semicircular annuloplasty with a thin GORE-TEX graft was carried out in two patients having tricuspid AV valve, and a favourable result was obtained. In bicuspid AV valvular regurgitation, two patients received the suturing-up of free margins of prolapsed leaflets, and the results were satisfactory. From these results we consider that the semicircular annuloplasty for dilated tricuspid AV valve and the suturing-up of free margins of dilated or prolapsing leaflets in quadricuspid or quintacuspid and bicuspid AV valves are the recommendable procedures. If more than mild AV valvular regurgitation remained after these valvuloplasties, the Kay's and/or DeVega's annuloplasties should be added for eliminating the regurgitation.
