Analysis of 9 cases of complete left bundle branch block after interventional treatment for ventricular septal defect
Abstract：Objective To investigate the risk factors and prognosis of CLBBB complicated with VSD after interventional therapy.Methods The general data and follow-up results of 9 cases of complete left bundle branch block (CLBBB) after interventional treatment for ventricular septal defect (VSD) were reviewed from April 2010 to December 2015 in our hospital heart center.The age of children,type of VSD and occluder,the occurrence time and prognosis of postoperative CLBBB and the change of LVEDD and LVEF were analyzed.Results Age:1 case ＞ 5 years and 8 cases ＜ 5 years;VSD and occluder type:perimembranous VSD with pseudo aneurysm in 3 cases and intracristal VSD in 6 cases;there was 1 case of symmetry occluder,2 cases of small waist big edge type occluder,and 6 cases of eccentric type occluder.Postoperative CLBBB occurrence time and prognosis:CLBBB occurred in postoperative 3 days in 8 cases,including 4 cases recovered to normal after drug treatment and 2 cases again had CLBBB in postoperative 1 month;1 case began to appear CLBBB in postoperative 1 month and returned to normal after receiving surgery the next day.Left ventricle enddiastolic dimension (LVEDD) and ejection fraction of LV (LVEF) changes:2 cases had increased LVEDD in 6 and 12 months after operation,respectively;the other 7 cases did not have obvious LVEDD increase;all the 9 cases did not have decreased LVEF.Conclusion VSD interventional therapy should strictly follow the expert consensus and standardized operation;VSD interventional occlusion therapy for young children (＜ 5 yrs) should be cautious;in the premise of ensuring the occlusion effect of interventional therapy,the symmetric type occluder should be selected first.CLBBB complicated with VSD after interventional therapy has a good recent prognosis,but in some cases the long-term LVEDD increases;CLBBB complicated with VSD after interventional therapy cases should be strictly followed up.
