"Cardiac Catheterization Calculator - Cardiology" is an app designed to help calculating various important parameters in catheterization procedure of congenital heart disease. There are four basic parameters that are characterised in this "Cardiac Catheterization Calculator - Cardiology" app, namely:

🔸 Flow ratio: parameter that is used to determine the severity of the shunt lesion, whether it is hemodynamically significant needing further treatment or not  
🔸 Pulmonary artery resistance index (PARI): parameter that is used to determine whether the shunt is correctable or not correctable due to high chance of developing pulmonary hypertension crisis after defect correction
