Why the study?
Whether the clinical impact of postoperative AF differs according to the type of thoracic surgery was unclear.
Does the risk of late-occurring atrial fibrillation following postoperative atrial fibrillation differ by the type of open thoracic surgery?
Population
2424 consecutive patients undergoing thoracic aortic, esophageal, or lung surgery
Comparison
POAF across thoracic aortic vs esophageal vs lung surgery, and POAF vs without POAF
Design
Observational cohort study
Key result
Late-occurring atrial fibrillation was observed in 31.0% of patients with postoperative AF versus 3.3% without, though recurrence rates differed significantly by the type of thoracic surgery.

May warrant surgery-specific AF surveillance after POAF; leaves open tailored strategies pending prospective validation.

Does the risk of late-occurring atrial fibrillation following postoperative atrial fibrillation differ by the type of open thoracic surgery?
Absolute Event Rate: 31% vs 3.3%
The risk of late-occurring atrial fibrillation following postoperative AF varies significantly depending on the type of thoracic surgery, suggesting that long-term monitoring and management strategies should be tailored to the surgical context.
Kashiwagi et al. (2026) conducted a cohort in Postoperative atrial fibrillation after open thoracic surgery (n=2,424). Postoperative atrial fibrillation (POAF) vs. No POAF was evaluated on Late-occurring atrial fibrillation (>30 days postoperatively). Late-occurring atrial fibrillation was observed in 31.0% of patients with postoperative AF versus 3.3% without, though recurrence rates differed significantly by the type of thoracic surgery.
