Effects of mild and severe right ventricular overload on right atrial reservoir, conduit, and pump function

	Baseline	Mild PA Band	P Value	Baseline	Severe PA Band	P Value
RA reservoir volume, ml	8.9 ± 1.4	8.3 ± 1.5	0.40	10.3 ± 1.3	8.1 ± 3.5	0.18
RV CV, ml	7.7 ± 4.0	12.2 ± 7.2	0.34	6.6 ± 2.3	10.2 ± 4.2	0.07
RV PV, ml	6.2 ± 1.3	5.5 ± 0.5	0.32	5.1 ± 1.3	5.5 ± 3.6	0.74
RA reservoir function	39 ± 5%	34 ± 8%	0.33	47 ± 6%	33 ± 4%	0.04
RA conduit function	33 ± 11%	42 ± 20%	0.44	30 ± 9%	43 ± 13%	0.01
RA booster pump function	28 ± 9%	24 ± 12%	0.55	23 ± 5%	24 ± 14%	0.94

Data are means ± SD. CV, conduit volume; PV, booster pump volume. P values were determined using repeated-measures ANOVA.
