AI summary — for doctors, generated from the abstract only

After PFO closure, ischemic stroke recurrence was low long-term, double-disc devices closed the shunt better than suture-based devices, and atrial fibrillation was common.

What was studied

Single-center registry of 331 consecutive patients (80% prior cryptogenic stroke) undergoing percutaneous PFO closure in Lucerne in 2017-2024, followed up to 8 years.

Key findings

  • Technical success was 99%.
  • Double-disc devices achieved effective closure in 97% versus 68% with suture-based closure.
  • Residual shunt may indicate higher cerebrovascular risk.
  • A considerable proportion developed atrial fibrillation after closure.

Clinical relevance

Device choice and post-closure rhythm surveillance are relevant to PFO closure practice.

Who should care

Cardiology

Limitations

This is an observational single-center registry without a comparison group, and the abstract omits exact event rates.

Prefer devices that achieve effective closure and watch for atrial fibrillation after closure.

Abstract

Background

Percutaneous patent foramen ovale (PFO) closure is established for selected patients with PFO-associated cryptogenic stroke and other dedicated indications; however, long-term outcome data remain limited.

Aims

Evaluate procedural, echocardiographic, and long-term clinical outcomes after percutaneous PFO closure.

Methods

Consecutive patients undergoing PFO closure at Heart Center Lucerne between February 2017 and December 2024 were analyzed. The primary endpoint was a combined endpoint of recurrent cerebrovascular events and death. Follow-up included 6-month echocardiography and clinical follow-up up to 8 years using electronic health records and structured telephone interviews.

Results

A total of 331 patients (mean age 51 ± 12 years, 39% women, 80% prior cryptogenic stroke) were analyzed. Atrial septal aneurysm was present in 31%, grade 3 shunt in 72%, and the median RoPE score was 7 (IQR 6-7). Technical success was 99%. Devices used were Amplatzer (52%), Figulla Flex (42%), NobleStitch (6%), and Gore (1%). Double-disc devices achieved higher effective closure (residual shunt ≤ grade 1) than suture-based closure (97% vs. 68%; p < 0.001); a double-disc closure for relevant residual shunt was required after 7/21 suture-based closures. During a median follow-up of 3.7 years (IQR 2.1-5.7) 12 patients had a primary outcome (three ischemic strokes, two hemorrhagic strokes, five transient-ischemic-attacks, and two deaths). The primary outcome rate was 0.93/100 patient-years and stroke recurrence rate was 0.39 per 100 patient-years. Residual shunt grade ≥ 2 showed a trend toward increased cerebrovascular risk (HR 4.3, 95% CI 0.9-20.9; p = 0.068). Atrial fibrillation was documented in 5.4% of patients during long-term follow-up.

Conclusions

Percutaneous PFO closure showed high technical success and low long-term ischemic stroke recurrence. Double-disc devices provided higher effective closure than suture-based closure, and residual shunt may indicate increased cerebrovascular risk. A considerable proportion of patients developed atrial fibrillation following PFO closure.
