Abstract: To investigate the mentality and behavior of children with congenital ventricular septal defect(VSD) and to explore the influence of interventional versus surgical procedure of VSD on mentality and behavior. Methods From January 2006 to May 2007, 132 children suffering from VSD, without associated structural cardiac anormalies, were divided into two groups: the interventional group(n=68) and the surgical group(n=64). The Achenbach Child Behavior Checklist(CBCL) edited by Xu Tao-yuan in 1992 was performed on these children before and 6 months after treatment. Sixty sex, age, education and achievement-matched normal children were enrolled as controls. ResultsMentality and behavior of children with VSD were abnormal. The total behavioral problem scores of the VSD children were significantly higher than those of the controls (P<001). Behavior abnormities of boys were depression, social flinch, physical complaints, assaults and violation of rules. Whereas girls presented depression, social flinch, physical complaints and violation of rules, which was significantly different from normal children(P<0.01 or P<0.05). The abnormal rates of mentality and behavior positively correlated with course of disease. The total cursory mark of the postoperative check result of the interventional and surgical groups, both in girls and boys, was evidently lower than those of the pre-operative children (P<0.05). The total and assault cursory mark of the post-operative check result of the interventional boys were lower than those of the surgical ones(P<005). The total and depression, social flinch, violation of rules cursory mark of the post-operative check result of the interventional girls were lower than those of the surgical ones (P<0.05). ConclusionVSD affects mentality and behavior of children, which should be paid more attention to, also early treatment and effective and safe. Circumferential pulmonary vein ablation alone is enough for paroxysmal AF treatment, while it combined with segmental pulmonary vein ablation and CFAEs ablation may result in high success rates.
