  • Effectiveness and safety of perventricular device closure in congenital perimembranous ventricular septal defects: A systematic review and meta-analysis

    Objective To investigate the safety and effectiveness of perventricular device closure (PDC) for congenital ventricular septal defects (VSD) by a meta-analysis.Methods PubMed, The Cochrane Library, EMbase and China Biology Medicine (CBM) databases were searched for studies on PDC of VSD up to October 2018 by computer. We included studies only with more than 80% patients diagnosed with perimembranous VSD. A meta-analysis was performed to obtain pooled estimates of success rate and incidences of complications with 95% confidence interval (CI). Subgroup analysis stratified by percentage of perimembranous VSD was performed. Risk difference (RD) was used in the comparison of perioperative data with follow-up data. Results Fifteen studies (2 randomized controlled trials, 3 retrospective cohorts, and other 10 retrospective single-arm studies) involving 4 164 patients (3 848 patients with perimembranous VSD) were included in this meta-analysis. The pooled success rate was 95.4%. Incidences of residual shunt, aortic insufficiency, tricuspid insufficiency, and third-degree atrioventricular block were 5%, 0.1%, 3%, and less than 0.001% respectively. Improvements of residual shunt and aortic insufficiency were confirmed in follow-up patients. Conclusion PDC of congenital perimembranous VSDs is safe and yields good results. Because some limitations can not be overcomed, multicenter randomized controlled trials are needed to confirm our results.

  • Efficacy of transthoracic device closure versus surgical closure on ventricular septal defects: A systematic review and meta-analysis

    Objective To compare the effects of transthoracic device closure and surgical closure on ventricular septal defect systemically. Methods A systematic literature search was conducted using the PubMed, EMbase, The Cochrane Library, VIP, CNKI, CBM, Chinese Clinical Trial Register, ClinicalTrials. gov and Wanfang Database up to July 31, 2016. Quality was assessed and data of included articles were extracted. The meta-analysis was conducted using RevMan 5.0 and Stata 14.0 software. Results Eleven studies were identified, including 5 RCTs and 6 cohort studies involving 2 504 patients. For success rate, there was no statistical difference between the transthoracic closure group and the surgical closure group in RCT (RR=0.99, 95%CI 0.96 to 1.03, P=0.70); the success rate in the transthoracic closure group was lower than that in the surgical closure group in the cohort study (OR=0.21, 95%CI 0.08 to 0.55, P=0.002). Both results of RCTs and cohort studies showed that compared with surgical closure, transthoracic device closure reduced duration of the operation (RCT MD=–79.38, 95%CI –95.00 to –63.76, P<0.000 01; cohort studyMD=–66.26, 95%CI –71.20 to –61.31, P<0.000 01) and hospital stay (RCTMD=–2.10, 95%CI –2.65 to –1.55, P<0.000 01; cohort studyMD=–3.99, 95%CI –6.03 to –1.94, P=0.000 1), and the patients with blood transfusion (RCT RR= 0.04, 95%CI 0.01 to 0.11, P<0.000 01; cohort studyOR=0.01, 95%CI 0.00 to 0.13, P=0.001). In the transthoracic closure group the risk of postoperative arrhythmia reduced (RCT RR=0.20, 95%CI 0.13 to 0.32, P<0.000 01; cohort studyOR=0.46, 95%CI 0.31 to 0.67, P<0.000 1). In the transthoracic closure group a higher postoperative valvular regurgitation risk in RCT induced (RR=1.45, 95%CI 1.07 to 1.96, P=0.02) and the rate of postoperative valvular regurgitation in cohort study reduced (OR=0.43, 95%CI 0.20 to 0.92, P=0.03). However, there was no statistical difference in postoperative residual shunt (RCT RR=0.96, 95%CI 0.57 to 1.62, P=0.89; cohort study OR=0.52, 95%CI 0.12 to 2.25, P=0.38). Conclusion Transthoracic device closure can shorten duration of the operation, hospital stay and reduce the patients with blood transfusion and post- and intraoperative arrhythmia risk. Therefore, transthoracic device closure may be a better approach for some ventricular septal defect patients.

  • Real-time Three Dimensional Echocardiography Guided Closure of Atrial Septal Defect through a RightMinithoracotomy in Comparison with Traditional Surgical Repair under Cardiopulmonary Bypass

    Objective To compare surgical results between real-time three dimensional echocardiography(RT-3DE) guided closure of atrial septal defect (ASD) through a right minithoracotomy and traditional surgical repair under cardiopulmonary bypass (CPB). Methods Sixty-four patients with secundum ASD received surgical repair in the First People’s Hospital of Honghe Autonomous Prefecture from April 2009 to April 2012. According to different surgical approach, all the patients were divided into group A and B. In group A, 35 patients underwent traditional ASD repair under CPB including 20males and 15 females with their age of 12-56 (16.4±4.0) years. In group B, 29 patients received real-time RT-3DE guidedASD closure through a right minithoracotomy without CPB, including 20 males and 15 females with their age of 15-50 (18.5±0.2) years. Operation time,postoperative mechanical ventilation time,hospital stay,chest drainage,mortality,morbidity and follow-up outcomes were compared between the 2 groups. Results Operation time (110.47±35.90 minutesvs. 159.32±20.60 minutes),postoperative mechanical ventilation time (10.40±22.30 hours vs. 16.40±12.20 hours),chestdrainage (106.71±85.20 ml vs. 146.70±75.63 ml)and postoperative hospital stay (4.0±1.0 days vs. 7.0±1.0 days)ofgroup B were significantly shorter or less than those of group A. In group A, 1 patient died postoperatively and 7 patientshad postoperative complications. In group B, there was no in-hospital mortality and 3 patients had postoperative complications.Postoperative morbidity of group A was significantly higher than that of group B (20.0% vs. 10.3%,P<0.05) . ConclusionFor ASD patients with definite surgical indications,RT-3DE guided ASD closure through a right minithoracotomy has more advantages over traditional surgical repair under CBP.

  • Efficacy of minimally invasive transthoracic closure of atrial and ventricular septal defects

    Objective To evaluate the efficacy and safety of transthoracic minimally invasive occlusion operation for the treatment of congenital atrial and ventricular septal defects. Methods The clinical data of 88 patients who underwent surgical occlusion operation from December 2015 to February 2017 were summarized. There were 52 males and 36 females, aged 6.8±7.5 years ranging from 1.6 to 24.0 years. All the patients were followed up by ultrasound and electrocardiogram at postoperative 3, 6 and 12 months. The efficacy of minimally invasive thoracotomy was analyzed by statistical methods. Results The patients were followed up for 3-15 (6.8±2.3) months, and the follow-up rate was 92.0%. Ultrasound showed occluder fixed well and no residual shunt, valve regurgitation, thrombosis or other complications occurred. The heart was reduced, the ejection fraction was greater than 55%, and heart function rating for all patients was grade Ⅰ. Conclusion Transthoracic mini-invasive surgical occlusion of atrial and ventricular septal defects is safe and effective. The short and middle-term effect is satisfying. It can be widely used in clinical, but multi-center and long-term follow-up and assessment still need to be carried out.

  • Transcatheter occlusion of ventricular septal defects

    Objective To access the feasibility, effectiveness and safety of transcatheter closure of ventricular septal defects(VSD) in 17patients. Methods Seventeen patients, aged 4 23 years, were selected by transthoracic echocardiography. The location of VSD was perimembranous in 16 patients and was muscular in 1 patient. And 1 patient with aneurysm formation. All cases had no severe pulmonary hypertension or right to left shunt. Membranous VSD underwent transcatheter closure with Amplatzer membranous VSD occluder or membranous VSD occluder made in China. Muscular VSD was closed by Amplatzer patent ductus arteriosus occluder. Results The VSD diameter ranged from 2.3 10.5 mm(5.75±2.10 mm). The device diameter ranged from 412 mm (7.12±1.67 mm). After application of the prosthesis there was no residual shunt in all patients. One patient developed grade I atrioventricular block and complete right bundle branch block. Two patients developed right bundle branch block after 3 4 days. No other compli...更多cations were observed in 1 12 months follow up. Conclusion The transcatheter closure of VSD appears to be a safe and effective method.

  • Clinical evaluation of endoscopic bronchial closure of central airway-pleural fistulas with the atrial septal defect occluders: long-term follow-up

    Objective To explore the safety and efficacy for patients with central airway-pleural fistula (APF) treated by atrial septal defect (ASD) occluder. Methods This was a retrospective study. Between January 2017 and October 2021, a total of 16 patients with postoperative APF were treated with ASD occluder through bronchoscope under local anesthesia combined with sedation. The efficacy and complication were recorded during and after the procedure. Results Sixteen patients were recruited in this study and the average age was 60.7 years (range 31 - 74 years). The main etiology for APF was lobectomy/segmentectomy (n=12), pneumonectomy (n=2), radical esophagectomy (n=1) or decortication for chronic empyema (n=1). Totally, 4 fistulas were located in right main bronchus, 3 in left main bronchus, 3 in right upper bronchus, 1 in right middle bronchus, 2 in right lower bronchus and 3 in left upper bronchus. The median diameter of APF was 7.8 mm (ranged from 4 to 18 mm) and the median diameter of ASD occluder inserted was 10.0 mm (ranged from 6 to 20 mm). Successful occlusion of APF was observed in 15 patients (15/16) and 1 patient died of multiple organ failure caused by bacteremia 14 days after the procedure. Fourteen patients were recruited for long-term follow-up, on a median follow-up period of 16.2 months (ranged from 3 to 46 months). There were 12 patients of complete remission and 2 patients of partial remission and only one patient took a second operation due to the enlargement of fistula and translocation of occluder. At follow-up, 4 patients died and the reasons were directly related to the primary etiology, and no patient died due to APF recurrence. Conclusion Endobronchial closure of central APF using ASD occluder is a minimally invasive but effective modality of treatment with satisfactory long-term outcome.

  • Application of adjustable curved sheath in transcatheter closure of atrial septal defect with internal jugular vein solely guided by transthoracic echocardiography: A case report

    A case of a 4-month-old child with an aortopulmonary fenestration weighing 6.6 kg who underwent successful transthoracic minimally invasive occlusion in our hospital was reported in this article. The child was transferred from the intensive care unit (ICU) to the general ward 1 day after surgery and discharged 5 days later. Compared with conventional ligation or repair of extracorporeal circulation for the aortopulmonary fenestration, the transthoracic minimally invasive occlusion is characterized by less trauma and faster recovery. However, it requires strict surgical indications and is not suitable for all patients with aortopulmonary fenestration.
