AI Insight
Researchers interviewed 48 stroke survivors who had a patent foramen ovale (PFO), a heart defect that can allow blood clots to pass through and cause stroke. Despite most participants undergoing successful transcatheter closure of the defect, they reported significant psychological and physical barriers to resuming physical activity, including fear and anxiety about exercise, concerns about the closure device, persistent fatigue, and cardiac irregularities. While some participants experienced improved fitness after closure, many reduced their physical activity levels compared to before their stroke.
Why it matters
This study reveals that PFO-associated stroke survivors face unique challenges in returning to physical activity even after their heart defect is repaired, suggesting that current medical guidance may be insufficient. The findings indicate a need for better post-procedure counseling and clearer return-to-activity guidelines to help patients safely resume exercise and improve their quality of life.

Background
The presence of a patent foramen ovale (PFO) in the heart is a risk factor for stroke due to the potential for paradoxical embolism. Given the implication of the heart in PFO-associated stroke and transcatheter closure, there may be unique factors that prevent patients from returning to physical activity.
Purpose
To elicit patient perceptions of physical activity after PFO-associated stroke and transcatheter closure.
Method
A purposive sample of 48 individuals who had a PFO-associated stroke participated in this study. Data were collected using semi-structured interviews and data were analyzed using Braun and Clarke’s thematic analysis methodology. NVivo software was used to manage data, code, and generate themes.
Results
Participants were on average 47.7 years of age (SD = 8.2). All participants were diagnosed with ischemic stroke or transient ischemic attack and 44 participants received transcatheter PFO closure. The main themes (and sub themes) related to perceptions of physical activity after stroke and closure were: (1) psychological barriers (fear and anxiety, and closure device apprehension); (2) variability in fitness performance (subjective fitness improvement and decline in physical activity compared to before their stroke); and (3) variability in physical recovery (lingering fatigue/neuro-fatigue, residual physical symptoms, and cardiac irregularities after closure).
Conclusion
PFO-associated stroke survivors reported several significant and unique barriers (e.g., cardiac irregularities) to engaging in physical activity after PFO-associated stroke and closure. Some participants also reported improved fitness after their closure procedure. These findings highlight the need for further research to better support patient recovery and reduce uncertainty surrounding return-to-activity recommendations.
