Table 2. Cardiac dimensions (in mm) from non-transgenic (control) and transgenic (CSQ) mice, aged 4–6 months.

	RA	LA	RV	LV	RVFW	LVFW	Septum
Control	3.3 ± 0.2	3.0 ± 0.2	2.5 ± 0.2	1.5 ± 0.5	0.43 ± 0.06	1.1 ± 0.04	0.9 ± 0.17
CSQ	5.6 ± 0.3**	6.5 ± 0.6**	3.9 ± 0.4*	3.1 ± 0.3*	0.83 ± 0.05**	1.4 ± 0.05**	1.3 ± 0.09**

Atrial measurements were taken at necropsy (6 control, 12 CSQ mice). Ventricular measurements were obtained from formalin-fixed and haematoxylin-eosin-stained subvalvular transverse sections (3 control, 6 CSQ mice). Values are means ± S.E.M.

^*P < 0.05

^**P < 0.01 vs. control. RA and LA, largest external diameter of the right and left atrium, respectively; RV and LV, largest internal diameter of right and left ventricular chamber, respectively; RVFW, right ventricular free wall; LVFW, left ventricular free wall.
