Correlations between atrial fibrillation and cardiac chamber size, and EF evaluated pre and postoperatively.

Preoperative		POAF	No POAF	p-value
	LA (mm)	45.15 $\pm$ 6.96	43.31 $\pm$ 6.9	0.006
	LV (mm)	52.45 $\pm$ 7.49	51.61 $\pm$ 6.68	0.21
	RV (mm)	33.55 $\pm$ 5.89	32.98 $\pm$ 5.31	0.28
	LVEF (%)	51.38 $\pm$ 8	51.85 $\pm$ 8	0.54
Postoperative
	LA (mm)	44.5 $\pm$ 6.58	42.61 $\pm$ 6.83	0.007
	LV (mm)	49.92 $\pm$ 7	49 $\pm$ 6.53	0.17
	RV (mm)	31.87 $\pm$ 4.84	31.82 $\pm$ 4.76	0.9
	LVEF (%)	49 $\pm$ 5.99	49.43 $\pm$ 6.55	0.5

All data were expressed as mean and standard deviation. LA, left atrium; LV, left ventricle; RV, right ventricle; LVEF, left ventricle ejection fraction; POAF, Postoperative atrial fibrillation; EF, ejection fraction.
