Impact of Post-Procedural Atrial Arrhythmia on Long-Term Cardiac Function and Quality of Life Following Patent Foramen Ovale Closure
Bibliographic record
Abstract
Background: Patent foramen ovale (PFO) is a common remnant of the embryonic development of the heart with an underestimated potential for morbidity and mortality. This study aimed to investigate the long-term impact of atrial arrhythmia (AA), a common complication after PFO closure, on cardiac function and quality of life (QoL) through a retrospective clinical analysis. Methods: Patients who underwent percutaneous PFO closure between January 2022 and June 2024 were retrospectively identified. All patients underwent 24-h Holter electrocardiogram (ECG) monitoring prior to the procedure to screen for baseline atrial fibrillation (AF). Cardiac function and QoL were assessed after intervention and at long-term follow-up using echocardiographic parameters and questionnaires (SF-36), respectively. Results: A total of 215 patients were included in this study. Sinus rhythm was present in all patients at baseline, and 26% developed AA during follow-up after PFO closure. The average follow-up period was 24 ± 7.8 months. Among the 56 patients with post-procedural AA, echocardiographic analysis showed that mitral E/A significantly increased at long-term follow-up compared to the immediate post-interventional period (1.20 ± 0.24 vs. 1.29 ± 0.18, P < 0.05). No statistically significant changes were observed in echocardiographic variables other than mitral E/A. In terms of QoL, only the score for social function improved significantly at long-term follow-up (65.21 ± 6.16 vs. 67.98 ± 7.59, P < 0.05), while no significant differences were found in the other subdomains. Conclusions: AA, the common complication of PFO closure, has no impact on the long-term cardiac function and QoL of patients.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
