Hypoplastic Tricuspid atresia. Usually with pulmonary atresia or stenosis. Underdeveloped RV. Common features are small RV with right-to-left shunting through an ASD causing cyanosis.

Common causes of GI bleeding in neonates
Necrotizing enterocolitis. Milk allergy. Enterocolitis that sometimes accompanies Hirschsprung disease. In the newborn, prolonged jaundice (over 2 weeks) is most commonly due

Neonate with increased lung volumes and localized lung opacity.
Neonate witheconium aspiration. Retained multiple coarse areas (strand-like densities following bronchovascular patterns).

Generally occur a fter 6 months of age. Most are ileocolic and the cause is idiopathic. Treatment is water-soluble or air enema reduction. Contraindicationsto enema reduction: Free air, Signs of peritonitis. Recurrent intussusception occurs in 5% to 10% of cases. Unilateral hyperexpansion of body. Hilar lobes in children, common causes
Aspirated foreign one or two nodes compressing bronchus.
Hyperinflated lung findings
Flattening or inversion of diaphragm. Widening of rib interspaces. Larger retrosternal and retrocardiac clear spaces.

Local: Renal vein. Inferior vena cava. Perirenal lymph nodes. Contiguous invasion of liver. Remote: Lungs. Liver. Bone.
MalrotationDuodenal-jejunal junction is not properly fixed by ligament of Treitz. Results in duodenal obstruction by peritoneal bands or twisting of duodenum (midgut volvulus).
Intrauterine fetal distress can lead to passage of meconium. Aspirated meconium particles cause obstruction of small peripheral bronchioles. Results in areas of subsegmental atelectasis and areas of overdistension. Coarse reticulonodular...
