AF Recurrence Counts and Results of Logistic Regression With Respect to LASI ≥/< 0.9 at Different Follow‐up Times
| LASI <0.9, n = 69 | LASI ≥0.9, n = 55 | Proportion P Value | Crude OR | Crude 95% CI | Crude P Value | Adjusted OR | Adjusted 95% CI | Adjusted P Value | |
|---|---|---|---|---|---|---|---|---|---|
| 28 days | 26 (38%) | 45 (82%) | 2 × 10−6 | 7.4 | (3.3‐18.0) | 2.9 × 10−6 | 7.7 | (3.3‐20.0) | 7.5 × 10−6 |
| 3 months | 30 (43%) | 47 (85%) | 4 × 10−6 | 7.6 | (3.3‐19.7) | 7.2 × 10−6 | 7.5 | (3.2‐19.7) | 1.4 × 10−6 |
| 6 months | 36 (52%) | 47 (85%) | 0.0002 | 5.4 | (2.3‐13.8) | 0.0002 | 5.2 | (2.2‐13.5) | 0.0003 |
| 12 months | 46 (67%) | 49 (89%) | 0.007 | 4.1 | (1.6‐11.9) | 0.005 | 3.9 | (1.5‐11.5) | 0.008 |
Abbreviations: AF, atrial fibrillation; BMI, body mass index; CI, confidence interval; HTN, hypertension; LA, left atrial; LASI, left atrial sphericity index; LV, left ventricular; LVEF, left ventricular ejection fraction; OR, odds ratio; TEE, transesophageal echocardiography.
In the adjusted model, we adjusted for treatment (TEE or conventional), AF duration, and interactions between treatment and AF duration. The LA volume, LVEF, LV volume, age, sex, smoking, HTN, dyslipidemia, β‐blockers, IHD, height, weight, and BMI were not included, as they did not significantly improve the fit.
