Methods 289 cases un- derwent transcatheter closure of ASD with ASO. Com- plications occurred in 9 cases. The complications in procedure included systemic circulatory systemic air embolism in 2, pulmonary air embolism in 1, pericar- dial tamponade in 1, ASO malposition requiring emer- gency surgical removal in 1, transient atrial extrasysto- les in 1 and sizing balloon rupture in 1 case. 2 cases with postoperative complications were found in the fol- low-up studies. These included perforation of mitral valve and ASO partially dislodged. In this study, 5 children with intraoperative complication received e- mergency therapy including surgical intervention, and others needed only follow-up, as the complications were transient or asymptomatic. Results There were no children death in this study. The 5 cases who re- ceived treatment were completely healing, and the oth- ers with intra - procedure complications were also had no sequela existed. Cases with mitral valve and ASO partially dislodged were still in follow-up studies, as the 2 patients having no symptoms. Conclutions Air embolism were occurred easily in atrial septal defect cases who received ASO therapy. Complications mainly caused by inappropriate operative procedure and some complications needed emergency treatments. Follow-up studies were important to cases with transcatheter oc- clusion therapy.展开更多
【目的】探讨P波离散度对高血压左心室肥厚患者心房颤动的临床价值。【方法】对本院自2010年4月至2013年3月收治的204例高血压左心室肥厚患者，根据患者的病理特征，将104例伴有心房颤动患者作为观察组，100例无心房颤动患者作为对照组...【目的】探讨P波离散度对高血压左心室肥厚患者心房颤动的临床价值。【方法】对本院自2010年4月至2013年3月收治的204例高血压左心室肥厚患者，根据患者的病理特征，将104例伴有心房颤动患者作为观察组，100例无心房颤动患者作为对照组，测量两组患者最大P波时限（Pmax ）、最小P波时限（Pmin）、P波离散度（P波离散度＝Pmax -Pmin），比较两组心电图和彩色脉冲多普勒超声心动检查指标左心室质量指数（LVMI）的差异性。【结果】观察组与对照组的P波离散度分别为（45．3±10．8）m s、（30．7±11．0）m s ，两组相比较差异有显著性（ P ＜0．05），观察组Pmax值明显高于对照组 Pmax值，两组相比较差异有显著性（ P ＜0．05）；观察组LVMI值为（152．4±14．9）g/m2，与对照组（101．1±9．2）g/m2比较，差异有显著性（ P ＜0．05）。【结论】P波离散度、Pmax是高血压左心室肥厚患者心房颤动的预测因子，其可为高血压左心室肥厚患者心房颤动的临床诊断提供关键的价值参考。展开更多
