BackgroundControversy persists regarding the management of patients with cryptogenic stroke and patent foramen ovale (PFO). We performed a meta-analysis of randomized controlled trials comparing PFO closure with medical therapy.Methods and ResultsA prospective protocol was developed and registered using the following data sources: PubMed, Cochrane Register of Controlled Trials, conference proceedings, and Internet-based resources of clinical trials. Primary analyses were performed using the intention-to-treat method. Three randomized trials comparing percutaneous PFO closure vs. medical therapy for secondary prevention of embolic neurological events formed the data set. Baseline characteristics were similar. During long-term follow-up, the pooled incidence of the primary endpoint (composite of stroke, death, or fatal stroke) was 3.4% in the PFO closure arm and 4.8% in the medical therapy group [risk-reduction (RR) 0.7 (0.48–1.06); p = 0.09]. The incidence of recurrent neurological events (secondary endpoint) was 1.7% for PFO closure and 2.7% for medical therapy [RR 0.66 (0.35–1.24), p = 0.19]. There was no difference in terms of death or adverse events between the two groups.ConclusionsWhile this meta-analysis of randomized clinical trials demonstrated no statistical significance in comparison to medical therapy, there was a trend towards overall improvement in outcomes in the PFO closure group.
