Abstract: Objective: To study contribution of noninvasive investigations and cardiac catheterization in making final diagnosis of patients with congenital cyanotic heart diseases. Methods: A Prospective study carried out at a Paediatric Cardiology center at a tertiary care hospital. One hundred children with congenital cyanotic heart diseases (CCHD) from 0-10 years formed the study group. All cases with history of cyanosis or found cyanotic on clinical examination were subjected to detailed clinical examination, Hb/PCV measurement, Chest radiograph and Electrocardiogram. A provisional clinical diagnosis was made. Diagnosis was confirmed with 2D and colour Doppler echocardiography. Selected cases were taken up for cardiac catheterization where precise anatomic diagnosis and hemodynamic abnormalities could not be clearly defined by echocardiography. The contribution of each of the noninvasive and invasive modality in reaching an accurate diagnosis was calculated. Results: Noninvasive investigations could make a diagnosis of CCHD in most of the cases but patients with DORV, TGA, and TAPVC with obstruction and complex lesions could not be differentiated. Cardiac catheterization was done in selected cases wherein aorto pulmonary collaterals, additional VSD and pulmonary artery anatomy could not be well defined on echocardiography. Cardiac catheterization gave additional information in 30.4% cases in this study. Conclusion: Though noninvasive evaluation including an echocardiography forms the main stay diagnosis of all congenital cyanotic heart disease, Cardiac catheterization is required in complex cases where important additional information can be obtained which is important for precise diagnosis and management including the surgical point of view.
