Impact of proximity of left atrium to descending aorta on left inferior pulmonary vein triggers or drivers of atrial fibrillation: A risk score model
Authors' conclusion
The proximity of the Dao-LIPV was correlated to the presence of LIPV triggers or drivers.
Study context
- Population
- Drug-refractory atrial fibrillation (AF) patients undergoing first-time catheter ablation, 2010–2019
- Participants
- 886 patients
- Exposure
- Descending aorta to left inferior pulmonary vein (Dao-LIPV) distance ≤2.5 mm and persistent AF as predictors of LIPV triggers or drivers
- LIPV triggers or driversn = 63
- Outcome
- Presence of LIPV triggers or drivers
