Abstract
Background: The aim of this meta-analysis was to compare the efficacy and adverse events of percutaneous occlusion among patients with sufficient and deficient rims. Methods: A systematic review of all articles published in the Pubmed, MEDLINE and Google Scholar databases was performed. Odds ratio (OR) and 95% CI were used as a measure of effect of the combination of studies. I2 with 95% CI was estimated to assess study heterogeneity. For the meta-analysis, a random effects model was used. Results: The systematic search identified ten studies which included 4355 patients; 2661 of those had sufficient rim and the remaining 1694 patients showed some rim deficiency. Implant failure rate was 4.13% CI 95% 3.53e4.72%. Compared to frequency of failures in the group with a deficient rim (5.43% CI 95% 4.35e6.50%), implant failure in patients with a sufficient rim was significantly lower (3.30% CI 95% 2.62e3.97%), OR 2.27 CI 1.34e3.83 (p 0.002). The combined adverse events were 5.19% CI 95% 4.22e6.35% vs 2.7% CI 95% 2.08e3.31% in the deficient vs sufficient rim groups respectively (OR 2.21 CI 0.93e5.29; p 0.07). Implant failures and adverse events were more frequent in patients with posterior inferior rim deficiency. Conclusion: Patients presenting a posteroinferior rim deficiency are associated to both, an increased incidence of closure failure and a combined adverse events occurrence. More studies on posterior rim deficiency are necessary to ensure the feasibility and safety of the percutaneous approach.
