Abstract:
BACKGROUND:Transcatheter foramen ovale closure (TPC) has emerged as a potential treatment option for patients with cryptogenic strokes and persistent foramen ovale (PFO). However, previous randomized controlled trials could hardly demonstrate any benefit compared to medical treatment (Med-Tx). Recently new data have become available which may change current practice of transcatheter PFO closure. METHODS:A systematic review and meta-analysis comparing TPC and Med-Tx based on all available multicentric randomized controlled trials was performed. The primary outcome of interest was the recurrence of stroke in both groups. RESULTS:Five studies met the inclusion criteria with 1829 patients in the TPC and 1622 in the Med-Tx group. The median follow-up was 4 years. In the intention-to-treat analysis we found a statistically significant relative risk reduction in recurrence of strokes in the TPC group compared to the Med-Tx group (pooled hazard ratio (HR): 0.32; 95% CI: 0.13-0.8; P = .018). Excluding one study due to potential publication bias resulted in a pooled HR of 0.48 (95% CI: 0.25-0.91, P = .024). Patients younger than 45 years of age (pooled HR: 0.35; 95% CI: 0.16-0.75; P = .007) and those with moderate to severe shunt (pooled HR: 0.28; 95% CI: 0.14-0.55; P < .001) were more likely to benefit from closure. CONCLUSION:According to our meta-analysis TPC plus antiplatelets was superior in terms of stroke prevention when compared to Med-Tx. Furthermore, patients with moderate to severe shunts and those younger than 45 years of age were found to benefit most from TPC.
