Left atrial scar burden determined by delayed enhancement cardiac magnetic resonance at post radiofrequency ablation: association with atrial fibrillation recurrence

Table 1 LA-scar quantification in AF patients.

Variable	AF-Recurrence [N=13, mean, std]	AF-Free [N=14, mean, std]	P-value
LA-Volume [mL]	128.49 ± 44.0	96.0 ± 38.5	0.06
LVEF [%]	58.93 ± 12.1	64.85 ± 6.2.1	0.092
LA-scar [cm²]	11.40 ± 7.6	16.56 ± 5.25	0.036
Age [years]	61.67 ± 9.3	62.23 ± 12.8	0.891
Gender [no. males]	10	10	-

LA= left atrium; LA scar (hyperenhanced area) was normalized by LA volume. N= number of patients; Std=standard deviation; RF= radio frequency; LVEF: left ventricle ejection fraction; AF: atrial fibrillation.
