Hypothesis
Is segmental ostial pulmonary vein isolation an effective treatment for paroxysmal atrial fibrillation?
Conclusion
The clinical response rate of patients with medically refractory paroxysmal atrial fibrillation is 78% at 6 months, reducing to 62% in the long term.
Supporting Evidence
- 78% of patients showed a clinical benefit over a follow-up period of 6 months.
- The clinical response rate dropped to 62% in the long-term follow-up after approximately 24 months.
- PV stenosis was the main cause for complications.
Takeaway
Doctors can help people with a heart problem called atrial fibrillation by using a special procedure to block certain veins in the heart, and many patients feel better after this treatment.
Methodology
Patients underwent clinical follow-ups at 3, 6, and 24 months after the procedure to evaluate success rates.
Limitations
Long-term success is based on patients with a 3 PV isolation approach, and silent episodes of atrial fibrillation may not have been captured.
Participant Demographics
117 patients (96 male, 21 female), aged 51±11 years.
