Objective A meta-analysis was performed for a comparison of outcomes between surgery and balloon angioplasty (BA) for native coarctation of the aorta (NCA) in pediatric patients. Methods Electronic databases, including PubMed, EMbase, Medline, Cochrane Library, Weipu Data, Wanfang Data and CNKI were searched systematically for the literature aimed mainly at comparing the therapeutic effects for NCA administrated by surgery and BA. Corresponding data sets were extracted and two reviewers independently assessed the methodological quality. Results Ten studies meeting the inclusion criteria were included, involving a total of 723 subjects. It was observed that compared with BA, surgery was significantly associated with a lower incidence of recoarctation (OR, 0.43; 95%CI, 0.30–0.63; P<0.001), repeat intervention due to recoarctation (OR, 0.40; 95%CI, 0.27–0.61;P<0.001) and lower residual transcoarctation gradient in mid to long term follow up (WMD –0.85; 95%CI, –12.34 to –3.76;P<0.001). Compared with BA, surgery was significantly associated with a longer hospitalization time (WMD, 19.40; 95%CI, 15.82–22.99;P<0.001). Incidence of aneurysm formation (OR, 0.64; 95%CI, 0.26–1.57;P=0.33), complications(OR, 1.77; 95%CI, 0.95–3.28; P=0.07), perioperative mortality (OR, 2.57; 95%CI, 0.87–7.61, P=0.09) and immediate transcoarctation residual gradient (WMD –1.66; 95%CI, –4.23–0.90; P=0.2) were not statistically different between surgery and BA. Conclusions Compared with BA, surgery was significantly associated with a lower incidence of recoarctation, repeat intervention due to re-CoA and residual transcoarctation gradient in mid to long term follow up. On the contrary, BA was significantly associated with a shorter hospitalization time. Incidence of aneurysm formation, perioperative mortality, complications and immediate transcoarctation residual gradient were similar between surgery and BA.
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.
Objective To summarize the clinical characteristics of coarctation of the aorta (CoA) associated with intracardiac anomalies in infants. Methods The data from August 2009 to August 2017 of 86 infants who were diagnosed with CoA associated with intracardiac anomalies were analyzed. Preoperative diagnosis, surgical findings and post-operation follow-up were analyzed retrospectively. There were 56 males and 30 females at age of 1–346 (95.1±78.0)d. All the included patients underwent single-stage repair of CoA associated with intracardiac anomalies. Results Mean operative time was 279.0±56.4 min, mean cardiopulmonary bypass time was 162.3±51.0 min, and mean aorta cross-clamp time was 74.7±25.2 min. Mean length of ICU stay and ventilation time was 7.4±4.7 days and 101.1±75.4 hours, respectively. The residual transcoarctation gradient before discharge was lower than pre-operative transcoarctation gradient significantly (42.3±17.7 mm Hg vs. 22.1±9.4 mm Hg, P<0.001), and 7 early deaths were observed after surgery. The mean follow-up time of 79 hospital survivors was 31.0±27.4 months. And no late death was found. Transcoarctation gradient of hospital survivors in the last time follow-up was 21.2±11.0 mm Hg. Transcoarctation gradient of 29 patients was higher than 20 mm Hg. However, only 4 patients with significant clinical symptom of lower limbs retardation were recommended for ballon angioplasty consultant. The cumulative recoarctation-free survival in 2-year follow-up was 69.2%. Conclusions To avoid early second-stage operations, single-stage repair of CoA associated with intracardiac anomalies is effective and safe, and the outcomes of early to mid term follow-up are satisfactory.
