Left-to-right shunting (45.0%) pulmonary outflow obstruction (34.4%) most frequently diagnosed categories, followed by left ventricular (8.3%), transposition great arteries (4.2%), conditions intracardiac mixing (3.9%), other lesions (4.2%). Compared Western studies, (p < 0.0001), particularly tetralogy Fallot critical stenosis, more frequent children. In contrast previous reports, coarctation aorta (5%) does not seem be uncommon patients. Conversely, aortic stenosis hypoplastic ventricle may rare these (1% vs 3% 3–7%). Other showed no consistent racial difference occurrence. patients Down's syndrome had septal defect (38%) as predominant lesion atrioventricular (25%). usually report a reverse pattern for two lesions. mortality rate total cohort 7.5%.
