Health-related quality of life in children with congenital heart disease following interventional closure versus minimally invasive closure.

Introduction: The presence of atrial septal defect (ASD) or ventricular septal defect (VSD) significantly affects children's quality of life and, if not treated adequately, can contribute to increased mortality. In this study, we evaluated and compared the health-related quality of life (HRQL) of children who underwent treatment using either minimally invasive closure (MIC) or interventional closure (IC). Materials and methods: In this observational and comparative study 199 children (2 to 4.5 years of age) underwent closure treatment for simple ASD or VSD at the Children's Hospital of Chongqing Medical University between February 2021 and September 2021. Of these, 116 were treated with IC and 83 with MIC. Both preoperative and postoperative HRQL scores were assessed using the PedsQLTM3.0 Cardiac Module and the children were followed up at 3 and 6 months after surgery. Results: The two groups did not differ significantly in terms of demographics, baseline clinical characteristics, or pre-operative data. The duration of anesthesia (45 mins vs. 109 mins), procedures (25 mins vs. 48 mins), and length of postoperative hospital stay (4.32 days vs. 6.87 days) in the IC group were significantly less than in the MIC group (P < 0.001). The incidence of postoperative pneumonia in the VSD patients who underwent MIC was significantly higher than in those who underwent IC treatment (28.9% vs. 0 percent, P < 0.001). The HRQL scores increased significantly in both groups following treatment and follow-up evaluations (P < 0.001). The mean HRQL score of the IC group 3 months after treatment was significantly higher than that of the MIC group (88.9 vs. 85.7, P < 0.001), indicating a significant increase from the baseline score compared with the MIC group (5.4 vs. 2.6, P < 0.001). The IC group also showed higher scores than the MIC group (P < 0.05) in the dimensions of "Heart Problems and Treatment," "Treatment Anxiety," and "Cognitive Problems," with higher scores indicating fewer problems. Conclusion: The health-related quality of life in children with ASD and VSD improved continuously regardless of IC or MIC intervention. However, IC led to better HRQL in the early postoperative stage.

Open heart surgery or echocardiographic transthoracic or percutaneous closure in secundum atrial septal defect: a developing approach in one Chinese hospital.

BACKGROUND: To study the clinical manifestations and advantages of open-heart surgery and echocardiographic transthoracic or percutaneous closure with secundum atrial septal defect (ASD). The surgeon's learning curve was also analyzed. METHODS: In all, 115 consecutive patients with ASD from May 2013 to May 2019 were enrolled. According to the operative procedure, patients were divided into three groups: group one (open repair group) (n = 24), where patients underwent ASD repair (ASDR) under cardiopulmonary bypass (CPB); group two (closed surgical device closure group) (n = 69), where patients (six patients ≤1 y and sixteen ≤10 kg) underwent transthoracic ASD occlusion under transesophageal echocardiographic (TEE) guidance; and group three (transcatheter occlusion group) (n = 22), where patients underwent percutaneous ASD occlusion under echocardiography. The clinical features and results of each group were analyzed. All patients were telephonically followed-up after 3 months. RESULTS: All the three methods treating ASD were successfully performed in our hospital. It was also a typical developing history of congenital heart disease (CHD) surgery in China. One patient in the group two was transferred to emergency surgery for occluder retrieval and CPB-ASDR. Eight patients experienced failed transthoracic or percutaneous occlusion, two of whom underwent unsuccessful percutaneous closure at another hospital. Two patients each in the groups two and three were intraoperatively converted to CPB-ASDR. Two patient in the group three was converted to transthoracic occlusion surgery. All patients were discharged without any residual shunt. The three-month follow-up also did not show any residual shunt and occluder displacement. CONCLUSION: In low-weight, infants, or huge ASDs with suitable rim for device occlusion, transthoracic ASD closure was successfully performed. Based on knowledge of ASD anatomy and skilled transthoracic occlusion of ASD, surgeons can perform percutaneous occlusion of ASD under echocardiographic guidance.

Application of perimembranous ventricular septal defects closure solely by femoral vein approach under transesophageal echocardiography guidance / 中南大学学报(医学版)

Objective:To investigate the feasibility and safety of perimembranous ventricular septal defects (PmVSD) closure solely by femoral vein approach under transesophageal echocardiography (TEE) guidance.Methods:From January 1,2014 to May 31,2016,26 patients with PmVSD in Second Xiangya Hospital were selected,with age at 3.2-6.0 (4.3±0.7) years old and body weight at 15.0-19.5 (16.7±1.4) kg.The diameter of VSD was 3.5-4.8 (4.1±0.3) mm.All patients were treated by percutaneous PmVSD closure solely by femoral vein approach under TEE guidance.The effect of the procedure was evaluated by TEE and transthoracic echocardiography (TTE).The clinical follow-up study was conducted by TTE at 1,3,6 and 12 month (s) after the procedure.Results:Twenty cases were successfully treated with percutaneous PmVSD closure solely by femoral vein approach under TEE guidance,and the success rate was 76.9％.Six patients were converted to perventricular closure under TEE guidance because the guide wire in two cases or catheter in other cases could not pass through PmVSD.The diameter of symmetrical VSD occluder was 6.0-7.0 (6.2±0.4) mm.The procedural time was 12.0-64.0 (26.8±6.3) min.The residence time at ICU was 1.8-2.4 (26.8±6.3) h.The in-hospital time was 4.0-5.0 (4.4±0.5) d.There were 3 patients with immediate post-operative trivial residual shunt and incomplete right bundle branch block (IRBBB).All patients survived with no peripheral vascular injury or complications such as tricuspid regurgitation,pericardial tamponade and pulmonary infection.The residual shunt disappeared in 3 patients and IRBBB became normal rhythm in 3 patients at 1 month follow-up time point.No patients suffered from occluder malposition,residual shunt,pericardial effusion,arrhythmia (atrio-ventricular block),aortic valve regurgitation and tricuspid regurgitation.Conclusion:TEE-guided percutaneous PmVSD closureby femoral vein approach is safe and effective.
