Comparison of transthoracic echocardiography with computed tomography in evaluation of pulmonary veins

Table 2 Comparisons of conventional echocardiographic left atrial and ventricular measurements

Characteristic	Patients without/with follow-up examination			Baseline vs. Follow-up
Characteristic	Without	with	P-value	Follow-up	P-value
N° in category	125	17		17
LA diameter, mm	41.6 ± 6.4	46.2 ± 5.7	0.0067	42.3 ± 5.5	0.00059
LV end-diastolic dimension, mm	48.8 ± 4.1	51.2 ± 4.5	0.026	49.4 ± 5.6	0.041
LV end-systolic dimension, mm	32.0 ± 4.1	34.1 ± 4.4	0.048	32.9 ± 5.7	0.29
LV ejection fraction, %	63.1 ± 6.3	60.5 ± 6.7	0.12	60.9 ± 8.8	0.89

P values are for differences between participants with baseline and follow-up or for paired differences of measurements at baseline and follow-up. LA diameter was assessed from parasternal view. Baseline and follow-up assessments refer to the measurements before PV ablation and at 12 months after ablation, respectively
LA left atrial, LV left ventricular
