兒童室間隔缺損介入封堵術(shù)后心律失常及其危險(xiǎn)因素分析
[Abstract]:Objective to investigate the arrhythmia and its risk factors after interventional occlusion of ventricular septal defect (VSD) and evaluate the safety and efficacy of VSD interventional occlusion. Methods the clinical manifestations, electrocardiogram (ECG) and / or dynamic electrocardiogram (ECG) and / or dynamic electrocardiography were reviewed and analyzed in the cardiovascular department of the Affiliated Children's Hospital of Medical University Of Chongqing in December, January 2014. Drawings, Transthoracic echocardiography (TTE), preoperative examination, intraoperative and electrocardiographic monitoring, and postoperative review of follow-up data. The arrhythmia and its risk factors after the successful operation of VSD closure were analyzed. Results all the children's Hospital Affiliated to Medical University Of Chongqing, January ~ December 2016, was 1.2014 years. 381 cases of VSD interventional occlusion were performed in the cardiovascular medicine department, including 186 men (48.8%), 195 women (51.2%), aged 1 years old (3 years old and July + 2 years). In this study, 367 cases were successfully blocked and the success rate was 96.3%. without death in 381 patients with ventricular septal defect interventional occlusion. Among them, 14 cases of closure failed, including interventricular failure. The anatomical position of the septal defect was too high, close to the aortic valve, the intervention risk was large, and 4 cases were given up. After the closure of the ventricular septal defect, the results showed that there were 4 cases of the reflux of the aortic valve; the defect was large and there were 4 cases of large residual shunt after closure; the intraoperative angiography showed that the flow of VSD defect was too small and the guide wire was unable to pass through. Of the 367 cases of successful closure of.2., of 2 patients with successful VSD closure, 84 had arrhythmia after operation, accounting for 58 cases of 22.89%. including 69%, including 32 incomplete right bundle branch block (38.1%), 8 complete right bundle branch block (CRBBB), 9.5%, and 1 complete left bundle branch block (CLBBB). 1.19%, 10 cases of left anterior branch block (LAFB), 6 cases of atrioventricular block (AVB), 3 cases (3.57%) of I degree atrioventricular block (AVB), 1 (1.19%) atrioventricular block (1.19%), 1 cases (1.19%) of atrioventricular block (AVB) and 1 cases (1.19%) with I degree AVB combined with conduction block, occurrence rate of 7.14%; origin, 7.14%; origin Abnormal types of arrhythmia were found in 26 cases (31%), including 9 cases (10.71%), 7 cases of frequent atrial premature beat (8.33%), 3 cases of frequent ventricular premature beat (3.57%), 3 (3.57%) of non paroxysmal tachycardia, 2 cases of wandering heart rhythm, 1 cases of borderline escape, non paroxysmal tachycardia combined with interfering atrioventricular dislocation. There were 3 cases of arrhythmia (including II AVB, III AVB, CLBBB), accounting for 3.57%. There were 1 cases of no arrhythmia before.3., whether or not the membranous tumor was combined, the time of operation, the diameter of the ventricular septal defect, the diameter of the interventricular septal defect, and the incidence of arrhythmia after the interventional procedure (P0.05). There was no significant correlation between the distance from the upper edge of the defect to the aortic valve (P0.05) and the occurrence of arrhythmia (P0.05). The reexamination of electrocardiogram (ECG) at the discharge of.4. showed that 36 cases had been restored to normal (36/84,42.9%), but 48 cases were still not disappearing. 3 cases of severe arrhythmia after operation, after the infusion of intravenous methylprednisolone, albumin, and dexamethasone were discharged after the discharge: (1) 1 cases of III AVB transformation (2) (2) 1 cases of II degree AVB transformation to LAFB; (3) 1 cases of CLBBB transformation to incomplete left bundle branch block.26 cases of abnormal cardiac arrhythmia after VSD intervention to give glucocorticoid to reduce edema, in 1 weeks to restore normal. Conclusion 1. arrhythmia is a common complication after VSD closure, which is incomplete. The sexual right bundle branch block (IRBBB) is the most common, and the occurrence of serious arrhythmia is not associated with the arrhythmia before the operation of a few.2., the size of the ventricular septal defect, the diameter of the ventricular septal defect, the size of the occluder, the length of the operation and the occurrence of arrhythmia after the VSD intervention. Therefore, we should be before the operation. The anatomical morphology of VSD was solved, the surgical indications were strictly observed, the appropriate occluder was selected according to the diameter of VSD, and the operation time was shortened as far as possible in order to reduce the occurrence of arrhythmia after VSD intervention and to standardize the treatment of.3., and the prognosis of arrhythmia after interventricular septal defect intervention was better.
