  • Hybrid Perventricular Closure for Pediatric Patients with Muscular Ventricular Septal Defect: Experience from West China Hospital

    ObjectiveTo investigate the efficacy and safety of hybrid perventricular device closure (PVDC) for the treatment of muscular ventricular septal defect (MVSD) in pediatric patients. MethodsWe retrospectively analyzed clinical data of 35 pediatric patients with MVSD who received hybrid PVDC in West China Hospital between 2009 and 2012. There were 16 males and 19 females with their median age of 3.9 years (range, 1 month to 7 years). There were 10 patients with single MVSD, 12 patients with multiple MVSD, 6 patients with other congenital heart defects, and 7 patients with post-surgical residual MVSD. ResultsAmong the 35 patients, immediate complete closure was achieved in 28 (80.0%) patients. Residual shunt was noted in 7 (20.0%) patients. Median device size was 5 mm. Cardiopulmonary bypass was avoided in 19 patients. Two (5.7%) patients died postoperatively due to postoperative heart failure resulted from complex congenital heart defect. All survival patients were followed up for a mean duration of 6 months, and there was no late death. Thirty-one (93.9%) patients had good positioning of the closure devices but no residual shunt. Small residual shunt at the apex was noted in 2 (6.1%) patients. ConclusionHybrid PVDC is an effective treatment for MVSD with relatively high successful rate but low mortality and morbidity, and its short-term results are satisfactory.

  • Analysis of Failure of Perventricular Device Closure of Ventricular Septal Defect

    摘要:目的:分析微创外科室间隔缺损(ventricular septal defect,VSD)封堵失败原因,以期提高术前超声心动图筛查水平。方法:回顾性分析25例微创外科VSD封堵失败改行修补术病例,对比超声表现及手术所见,归纳总结产生并发症的原因。结果:残余分流与VSD假性膜部瘤右室面具有多个出口和低估VSD大小密切相关;VSD合并主动脉瓣右冠瓣脱垂是主动脉瓣反流的主要原因;封堵器移位与低估VSD大小且使用偏心封堵器有关;原有三尖瓣反流加重和发生Ⅲ度房室传导阻滞VSD均位于隔瓣下方;封堵失败组较封堵成功组缺损偏大,差异具有统计学意义(Plt;0.05)。结论:超声心动图对VSD及其毗邻结构的细致评估,有助于严格适应证,提高手术成功率。 Abstract: Objective:To analyze the failure of perventricular closure of ventricular septal defect (VSD), in order to improve the preoperative echocardiography examination. Methods: Twentyfive cases underwent surgical repair after failure of perventricular closure of VSD were included in this study. With combination of echocardiographic and surgical findings, retrospective analysis of the failure of perventricular closure of VSD were attempted to summarize the cause of complications.Results: Residual ventricular communication was due to underestimation of size of VSD and pseudomembranous aneurysm resulting in multiple outlets of VSD on the right ventricle side; preoperative prolapse of rightcoronary cusp was the main reason for mild or greater than mild aortic valve regurgitation after eccentric device closure of VSD; Underestimation of the size of VSD and using eccentric occluder device were responsible for the displacement of VSD occluder device. Postoperative aggravated tricuspid regurgitation and Ⅲ°atrialventricular block (AVB) were attributed to VSDs located under the septal leaflet of tricuspid valve. The size of VSD in group of failed perventricular device closure of VSD was larger than that in group of successful device closure of VSD,and the difference was significant(Plt;0.05). Conclusion: Echocardiography vividly reveals VSD and adjacent structures, which should be used in accessing the anomaly and defect and formulating surgical plans to reduce surgical morbidity and mortality.

  • Outcome assessment of different surgeries for neonates with pulmonary atresia and ventricular septal defect

    Objective To explore the feasibility and option of different surgeries for neonates with pulmonary atresia and ventricular septal defect (PA/VSD) through assessing the effect of common surgeries. Methods Fourteen neonates who underwent their first surgery in our center from July 2004 to October 2014 were included. Their basic characteristics, operation and pre- and postoperative clinical information were extracted. Follow up was conducted and the last visit was on October 10, 2016. Short- and midterm survival and total correction rate were compared among different surgeries. Results Among the 14 patients, there were 4 (28.6%) patients, 6 (42.9%) and 4 (28.6%) who underwent one-stage repair, right ventricular outflow tract (RVOT) reconstruction, and systemic to PA shunt operation respectively. The overall in-hospital mortality after the first operation was 28.6% (4/14). At last visit, no death occurred resulting the 5-year survival rate of 71.4% (10/14). The overall total correction rate for all neonates was 64.3% (9/14). Although no statistical difference was found in the mortality among the one-stage repair , RVOT reconstruction and systemic to PA shunt group(50.0% vs. 33.3% vs. 0.0%, P=0.280), the survival and hazard analysis implied better outcomes of the systemic to PA shunt palliation operation. There was no statistical difference in the total correction rate and months from the first palliative operation to correction between those who underwent RVOT reconstruction and systemic to PA shunt (75.0% vs. 50.0%, P=0.470; 32.0 months vs. 18.0 months, P=0.400). Conclusion Performing surgeries for neonates with PA/VSD is still a great challenge. However, the midterm survival rate was optimistic for the early survivors. Systematic to PA shunt seemed to be a better choice with lower mortality for the neonates with PA/VSD who need the surgery to survive.

  • Clinical efficacy of transthoracic occlusion via a right subaxillary incision and conventional surgery in the treatment of ventricular septal defect: A retrospective cohort study

    ObjectiveTo analyze the clinical efficacy of transthoracic occlusion via a right subaxillary incision and conventional surgery in the treatment of ventricular septal defect (VSD).MethodsThe clinical data of patients with congenital VSD undergoing right subaxillary incision surgery in our hospital from January 2017 to January 2020 were retrospectively analyzed. According to the surgical methods, the patients were divided into two groups: a conventional surgery group (conventional group) and a transthoracic occlusion group (occlusion group). There were 221 patients in the conventional group, including 97 males and 124 females, with an average age of 2.6±2.2 years and an average weight of 13.4±6.2 kg; there were 185 patients in the occlusion group, including 90 males and 95 females, with an average age of 3.2±2.6 years and an average weight of 14.7±6.6 kg. The clinical effectiveness was compared.ResultsThe success rate of surgery was 100% in both groups. The intraoperative blood loss was less in the occlusion group (P<0.05). The incision length, operation time, postoperative mechanical ventilation time, retention time in the intensive care unit, the time to resume normal diet and normal activities after operation were all shorter than those in the conventional group (P all <0.05). The total cost during hospitalization of the conventional group was less than that of the occlusion group (P<0.001). There was no statistical difference in the incidence rate of perioperative complications between the two groups (P>0.05). During the follow-up (15.8±8.8 months), the incidence of complications in the conventional group was higher than that in the occlusion group with a statistical difference (P<0.001).ConclusionCompared with conventional surgery, transthoracic occlusion for VSD via right subaxillary incision has the advantages of smaller incision, shorter operation time, less blood loss, shorter postoperative recovery time and less long-term complications. However, the total hospitalization cost is relatively high, mainly because of the high consumables cost, and the long-term effects still need further comparative observation.

  • Minimally invasive experiences and medium-long-term results of perventricular device closure of ventricular septal defects in 783 children: A retrospective analysis in a single center

    ObjectiveTo summarize the minimally invasive experiences and medium-long-term results of perventricular device closure of ventricular septal defects (VSD) under transesophageal echocardiography (TEE) guidance.MethodsWe retrospectively analyzed the clinical data and medium-long-term follow-up results of 783 patients who undertook perventricular device closure under TEE guidance in Dalian Children’s Hospital from July 2011 to January 2020, in which perimembrane VSD were found in 598 patients, VSD with aortic valve prolapse in 135 patients and muscular VSD in 2 patients. There were 463 males and 320 females at age of 5 months to 13 years with average age of 3.3±1.2 years, and body weight of 5.9-51.0 (15.9±8.3) kg. The left ventricular defect diameter of the VSD ranged from 5.0 to 11.0 mm, with an average of 6.3±1.2 mm. The right ventricular defect diameter of the VSD ranged from 2.3 to 8.0 mm, with an average of 4.3±0.9 mm.ResultsThe procedures were completed successfully in 753 patients. The device of 1 patient (0.1%) fell off and embedded in the right pulmonary artery after the operation, and the occluder was taken out and the VSD was closed with cardiopulmonary bypass (CPB) in the secondary operation. One patient (0.1%) appeared Ⅲ degree atrioventricular block in 2 years after operation. The device was taken out and VSD was closed with CPB in the secondary operation, and the patient gradually reached to sinus rhythm in post-operation. Eight patients (1.1%) presented delayed pericardial effusion in 1 week after operation, and were cured by pericardiocentesis with ultrasound-guided. Symmetric occluders were used in 580 patients, eccentric occleders were used in 171 patients and muscular occluders were used in 2 patients. The follow-up time was 9 months to 9 years. The rate of loss to follow-up was 96.7% (704/728). No residual shunt, occlude-loss or arrhythmia was found during follow-up. Conclusion The minimally invasive penventricular device closure of VSD guided by TEE is safe and availabe. Medium-long-term follow-up results are satisfactory, it is worthy of clinical promotion, and longer term follow-up is still needed.

  • Twenty-two patients of atrioventricular septal defect repair with prosthetic valve ring implantation: A retrospective cohort study in a single center

    ObjectiveTo review the characteristics of patients who underwent atrioventricular septal defects (AVSD) repair with prosthetic valve ring implantation in our hospital, and to analyze the safety and effectiveness of this intervention.MethodsThe clinical data of all patients diagnosed with AVSD who received surgery repair and prosthetic valve ring implantation from January 1, 2018 to July 12, 2020 in Guangdong Provincial People's Hospital were collected and analyzed. There were 22 patients with 9 males and 13 females at a median age of 35.00 (14.10, 53.00) years. There were 9 (40.9%) patients with prosthetic half or full rings placed on the left atrioventricular valve and 18 (81.8%) patients with prosthetic half or full rings placed on the right atrioventricular valve. ResultsThe median postoperative hospital stay was 7.00 (6.00, 8.80) d, and the postoperative mechanically assisted ventilation time was 11.00 (6.25, 19.00) h. There were 2 (9.1%) patients of moderate or higher postoperative atrioventricular valve regurgitation, 1 on the left and 1 on the right. There was one patient (4.5%) of the postoperative residual septal defect. There was no left ventricular inflow or outflow tract obstruction and no postoperative residual atrial septal defect during the follow-up of 152.00 (124.00, 1 030.00) d.ConclusionImplantation of a prosthetic ring is safe and effective in patients with AVSD, and the structural strength of the ring may be improved after the implantation. The physiological development of the AVSD annulus after prosthetic ring implantation and the results of long-term follow-up needs further attention.

  • Atrioventricular septal defect: A case report

    The patient, male, 1 year, was admitted to our hospital with cardiac murmur. Cardiac ultrasonography showed "complete atrioventricular septal defect (C-AVSD), secondary orifice atrial septal defect (ASD), patent ductus arteriosus (PDA), left superior vena cava, and pulmonary hypertension". The patient got follow-up at the age of 3, 6, 9 months and 1 year, with no feeding difficulties, no obvious underdevelopment and no history of repeated respiratory infections. Cardiac ultrasonography showed that the ventricular septal defect (VSD) healed spontaneously at 9 months of age. At 1 year of age, he was admitted to the hospital with "partial atrioventricular septal defect (P-AVSD)" and accepted surgery. Intraoperative exploration showed that the primary orifice ASD was 12 mm, the atrioventricular valve was divided into two groups, and the left atrioventricular valve had three leaflets: anterior, posterior, and lateral one. A cleft was between the anterior and posterior leaflets. The annulus was not enlarged with diameter of 13 mm. The right atrioventricular valve developed well, with fibrous hyperplasia and adhesion under the septal valve. No VSD was seen. The cleft was sutured intermittently. Autologous pericardial patch was used to repair the primary orifice ASD, and the coronary sinus was separated into the right atrium. Self-healing of VSD patients with C-AVSD is very rare, suggesting that patients with C-AVSD with normal range of development, and without obvious clinical symptoms and secondary damage, should be followed up and accept elective surgery in clinical practice.
