The median age was 6 years (interquartile range 3.5-9 years). Confluent Branch pulmonary arteries were present in 395 (99%) children. Pulmonary artery abnormalities were detected in 72 (18%) patients. Two hundred and eleven (53%) children had 283 major aortopulmonary collateral arteries with 88 having 2 or more major aortopulmonary collateral arteries. Out of all, 195 (92%) had hemodynamically significant Major aortopulmonary collateral arteries (supplying ≥3 lung segments) with 54 (28%) having small (&lt;1.33mm at origin), 105 (54%) moderate (1.33-1.67 mm at origin) and 36 (18%) large (&gt;1.67 mm at origin) caliber.</p><p><strong>Conclusion:</strong> The frequencies of pulmonary artery abnormalities and various anatomic variations missed on echocardiography in the studied population were high. Diagnostic cardiac catheterization is still a relevant invasive diagnostic procedure in children with tetralogy of fallot.</p><p>Keywords: , , , , , , .</p> ER -
