Abstract


Acynotic congenital heart disease is because of left to right shunt seen in Atrial Septal Defect (ASD), Ventricular Septal Defect (VSD) and Patent Ductus Arteriosus (PDA). Left to right shunt leads to Pulomonary artery hypertension (PAH) because of increased volume of flow and sheer pressure forces that combine to damage the pulmonary vasculature. Over a long time, the hyperkinetic PAH becomes fixed and leads to reversal of shunt (Eisenmenger syndrome). These congenital heart diseases are associated with better surgical outcome if timely diagnosed and operated. PAH may even come to normal baseline level and  the child may live a normal healthy life if got evaluated and treated at an early stage. The current study was proposed to compare the echocardiography and  99m – TC Radionuclide scan (MAA) to detect and quantify reversal of shunt in Acynotic congenital heart disease in children.
