Larger left atrial diameter (LAD) showed in AF patients with RHD

Clinical characteristics	SR (n = 12)	AF (n = 12)
Gender (m/w)	6/6	6/6
Age (y)	50.08±7.20	49.25±6.84
AF time (m)	--	15.75±4.16
NYHA (I/II/III)	2/7/3	2/6/4
LAD (mm)	34.17±3.64	51.25±4.96*
RAD (mm)	37.08±2.50	36.92±3.20
LVEF (%)	57.58±3.37	54.75±3.74

Note: Gender and grade of heart function were compared by using Fisher exact probability method; m/w = male/female; y = year; m = month; NYHA = New York heart function classification; LAD = left atrial diameter; RAD = right atrial diameter; LVEF = left ventricular ejection fraction;
