TABLE 1.

The density of connexin (Cx) 40 and Cx43 in the pulmonary vein (PV) and left atrium (LA) from control and mitral regurgitation (MR) dogs

	Cx40 (μm2/μm2)		Cx43 (μm2/μm2)
Groups	PV	LA	PV	LA
Control (n=6)	1.18±0.3%	1.49±0.3%	1.56±0.5%	1.56±0.3%
MR (n=5)	0.57±0.2%*	1.43±0.4%	0.48±0.2%*	1.38±0.2%

^*In dogs with MR, significant differences were found in the PV compared with control dogs
