Comparisons of periventricular device closure, conventional surgical repair, and transcatheter device closure in patients with congenital ventricular septal defects: A Protocol for Systematic Review.

BACKGROUND

Surgical treatments for ventricular septal defects (VSDs) mainly include 3 approaches: conventional surgical repair (CSR), transcatheter device closure (TDC), and perventricualr device closure (PDC). PDC has been introduced in over 10 years, although there remain concerns about adverse events. This network meta-analysis is to compare PDC, CSR, and TDC in the treatment of congenital VSD.

METHODS

We will search MEDLINE, EMBASE, Clinical Trials, Cochrane Library, and China National Knowledge Infrastructure databases for comparative studies on device closure and conventional repair for congenital VSDs to August 2019. A network meta-analysis with frequentist frame will be performed to compare the 3 approaches involving the success rate, in-hospital indexes, and incidences of complications, using risk ratio with 95% confidence intervals.

RESULTS

This study will be submitted to a peer-reviewed journal for publication.

CONCLUSION

This network meta-analysis will assess the safety and efficacy of PDC, CSR, and TDC in the treatment of congenital VSDs, and provide more evidence-based guidance in clinical practice.
