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.
ObjectiveTo summarize clinical outcomes of atrial septal defect (ASD)occlusion for patients with ASD and tricuspid regurgitation (TR). MethodsBetween July 2006 and January 2012, 98 patients with ASD and TR under-went ASD occlusion in Xinhua Hospital, Shanghai Jiaotong University School of Medicine. There were 36 male and 62 female patients with their age aging from 2 months to 80 years. All ASD were secundum ASD with their diameter of 3-23 mm. There were 60 patients with mild TR, 28 patients with moderate TR, and 10 patients with severe TR. All the patients received ASD closure without specific management for TR, including 51 patients under digital subtraction angiography (DSA), 46 patients via a minithoracotomy approach, and 1 patient guided by transthoracic echocardiography. All the patients were followed up with echocardiography to evaluate changes of TR after ASD closure. ResultsThere was no in-hospital death. ASD occlusion was not successful in 1 patient who was found to have residual ASD shunt on the third postoperative day. Another patient underwent reexploration for abnormal bleeding on the third postoperative day. All the other patients had uneventful postoperative recovery. Eighty-four patients were followed up for 1-64 (26.56±21.35)months. During follow-up, the patient who have residual ASD shunt on the third postoperative day received open chest repair 6 months after discharge. TR of 73 patients (86.90%)improved in different degrees. Preoperative severe TR in 10 patients changed into mild TR in 8 patients, moderate TR in 1 patients and still severe TR in 1 patient. Preoperative moderate TR in 26 patients changed into none TR in 6 patients, mild TR in 18 patients and still moderate TR in 2 patients. Preoperative mild TR in 48 patients changed into none TR in 40 patients and still mild TR in 8 patients. ConclusionFor patients with ASD and TR, conservative treatment strategy is recommended. Simple ASD closure can provide satisfactory clinical outcomes, and also avoid adverse complications of cardiopulmonary bypass including myocardial injury and lung injury.
Objective A meta-analysis was performed for a comparison of outcomes between transcatheter closure and transthoracic closure for simple congenital heart diseases (CHD). Methods Electronic databases, including PubMed, EMbase, Scopus, CNKI, Wanfang Data and Weipu Data were searched systematically for the literature aimed mainly at comparing the therapeutic effects for CHD administrated by transcatheter closure and transthoracic closure. Corresponding data sets were extracted and two reviewers independently assessed the methodological quality. The meta-analysis was conducted with Revman 5.3. Results Twelve studies meeting the inclusion criteria were included, involving 8 studies regarding to atrial septal defect (ASD), 2 studies regarding to ventricular septal defect (VSD) and 2 studies with regard to patent ductus arteriosus (PDA). A total of 1 423 patients were included. It was observed that compared with transthoracic closure, transcatheter closure entailed a lower complication rate (OR=5.62, 95%CI 2.78 to 11.36, P<0.001). However, meta-analysis of operative success rate(OR=1.65, 95%CI 0.92 to 2.98, P=0.09), instantly (OR=0.75, 95%CI 0.40 to 1.41, P=0.37) and long-term (OR=0.72, 95%CI 0.25 to 2.05, P=0.54) persistent shunt after surgery showed no significant differences between two approaches. No publication bias was found according to the funnel plot of complication rate and operative success rate. Conclusion In the treatment of simple CHD such as ASD, VSD and PDA, compared with transthoracic closure, a lower complication rate were associated with transcatheter closure. Meanwhile, operative success rate, instantly and long-term persistent shunt after surgery were not statistically different between the two surgical approaches. However, this study was based on retrospective studies, the level of evidence remained low. More large sample size randomized controlled trials should be designed to explore the safety and effectiveness of these two approaches in the treatment of CHD.
