Atrial pathology of Fontan hearts versus control hearts

	RIGHT ATRIUM		p value	LEFT ATRIUM		p value
	Fontan (n=47)	Controls^* (n=15)		Fontan (n=47)	Controls^* (n=8)
Wall thickness (mm)	3.0±1.0 (1.7-7.0)	1.8±0.4 (1.0-2.5)	<0.001	2.3±0.6 (1.0-4.0)	1.8±0.5 (1.0-2.3)	0.024
Fibrosis (%)	21±10 (7.9-47.4)	16±5 (9.3-23.9)	NS	21±9 (6.8-43.2)	28±8 (18.3-43.0)	NS

Fibrosis pattern^§
Interstitial	36/40	8/13	NS	33/40	5/8	NS
Focal	1/40	0/13		4/40	1/8
Mixed	3/40	5/13		8/40	2/8

Control data available for 15 right atrial specimens, but only 8 left atrial specimens

Poor slide quality prevented accurate determination of fibrosis pattern for 7 Fontan and 2 control hearts
