TRICUSPID ATRESIA
Tricuspid atresia is a cyanotic congenital heart disease in which the non oxygenate blood can not flow from right artrium to right ventricle due to under development of tricuspide valve.
Majority of infants with die in the first year of life without surgery. ASD,VSD,PDA are necessary for reaching the blood from right atrium to left system and with out them the infants will not survive.
Inferior vena cava and superior vena cava collect venous non oxygenate blood into right atrium. Through ASD blood reach to left atrium and finally flow into left ventricle and via aorta artery goes into the rest of body. This blood is the mixture of saturated and unsaturated oxygen. If there is VSD, this mixed blood in left ventricle come into right ventricle via VSD , then via pulmonary artery flows into pulmonary bed and becomes oxygenate ,then returns back into left atrium . In presence of PDA, the mixed blood in aora flow from this passage into pulmonary artery and pulmonary bed.
