Data presented as mean ± SD or number (%). UVH, Univentricular heart; TGA, d-transposition of great arteries; LRS, left to right shunt; TOF, tetralogy of Fallot; HLHS, hypoplastic left heart syndrome; IAA, interruption of aorta; HAA, hypoplastic aortic arch; DORV, double outlet right ventricle; HRV, hypoplastic right ventricle; VSD, ventricular septal defect; AVSD, atrioventricular septal defect; HR, heart rate; MAP, mean arterial pressure; PGE1, prostaglandin E1; BUN, blood urea nitrogen.
P values for comparisons between groups I and II (neonates) and between groups III and IV (infants).
Of 24 patients, 22 underwent right ventricle-pulmonary artery conduit, 1 modified Blalock-Taussig shunt, and 1 an aortopulmonary shunt.
