Most common cardiac diagnosis of infants undergoing cardiac surgery from 2009 to 2014. VSD: ventricular septal defect; PDA: patent ductus arteriosus; TOF: Tetralogy of Fallot; ASD: atrial septal defect; PS: pulmonary stenosis; CTGA: complete transposition of the great arteries; AO: aorta; AOV: aorta velocity; PA: pulmonary artery; PAV: pulmonary artery velocity. The laboratory data were considered to be statistically significant when .
