Right Atrial Remodeling Parameters Predictive of Recurrences After AF Ablation (Out of Blanking Period)

	Univariate			Multivariate
	HR	95% CI	P value	HR	95% CI	P value
Volume, per 10 mL	1.067	1.000–1.138	0.052
Area, per 10 cm2	1.081	0.983–1.189	0.106
Total fibrosis, %	1.014	0.979–1.051	0.44
Interstitial fibrosis, %	1.035	0.938–1.143	0.49
Dense scar, %	1.021	0.969–1.077	0.44
Sphericity	1.121	1.006–1.248	0.038	1.121	1.006–1.248	0.038

AF indicates atrial fibrillation; and HR, hazard ratio.
