Abstract

Introduction and objectives: At the end of 2017, three clinical trials demonstrated that, in selected patients, percutaneous closure of patent foramen ovale (PFO) after cryptogenic stroke (CS) reduces the risk of recurrence. Our aim was to determine the impact of these findings on routine clinical practice in a tertiary hospital.

Methods: Patients with CS and percutaneous closure of PFO during 2001-2020 were included. The clinical characteristics of the patient and the anatomical characteristics of the foramen were analyzed. Based on both, the closure indications were classified into three groups according to the latest European recommendations and were analyzed in two periods, before and after the publication date of the clinical trials.

Results: A total of 293 patients were included. The mean age was 49 ± 11 years, and 15% were older than 60 years. The median RoPE score was 6 [p25-75, 5-7] and 75% had complex anatomy (CA). After the publication of the studies, the frequency of CA and the mean age of the patients were significantly higher (89% vs. 69% p < 0.0005 and 51 ± 11 vs. 48 ± 11 years, p = 0.02, respectively), and the RoPE score, significantly lower (5 [5-7] versus 6 [5-7], p = 0.02). Inadequate closure indications were significantly reduced (8% vs. 18%, p = 0.02).

Conclusion: After the publication of clinical trials that have shown benefit of PFO closure after CS, the number of inappropriate indications for closure has decreased significantly in our institution, with a higher percentage of CA, despite a clinical profile suggestive of lower causal probability of PFO.
