Abstract:
Objective The aim of this article is to review and analyze the timing and surgical management of mediate and severe atrioventricular valve regurgitation(AVVR) in single-ventricle patients.Methods Between June 2006 and October 2011,twenty-three cases of single-ventricle patients accompanied with AVVR underwent atrioventricular valve plasty or replacement.There were 17 males and 6 females.Their ages ranged from 2.1 to 22.0 years,and their weight from 12.5 to 59.0 kg.There were 3 cases of A type of single ventricle,17 of B type,2 of C type,and 1 of D type.All cases had one atrioventricular valve except one of D type with 2 groups of atrioventricular valves.There were 18 patients with sever AVVR and 5 with the moderate.Before the management of AVVR,12 patients had undergone the first stage palliation,including B-D Glenn procedure 11 cases and A-P shunt 1 case.The periods between the two stages operations were 7-96 months.Among the all,there were 7 cases of atrioventricular valve replacement ; 3 cases of atrioventricular valve replacement and TCPC ; 5 cases of atrioventricular valve replacement and B-D Glenn procedure ; 2 cases of atrioventricular valve repair and TCPC ; 4 cases of atrioventricula repair and B-D Glenn procedure; 1 case of atrioventricular valve repair,B-D Glenn procedure and TAPVC repair; 1 case of atrioventricular valve repair,B-D Glenn procedure,PA Banding and TAPVC repair.Results In this group,there were 65.2％ patients who underwent atrioventricular valve replacement.The ones with moderate regurgitation underwent atrioventricular valve repair.Only 3 of the 18 cases with severe regurgitation could underwent atrioventricular valve repair(P =0.002).Three cases died.The mortality was 13％.All cases undergone atrioventricular valve repair were alive.The mortality of atrioventricular valve replacement was 20％.All the post-operative alive were followed up.Their follow-up period were between 0.8-6.3 years,withoud a dead case.Conclusion The regurgitation with single ventricle should be managed before the image of myocardium occurred.It is the best time to manage the atrioventricular valve when the regurgitation was moderate.The atrioventricular valve replacement is effective to the cases of single ventricle with severe AVVR.
