This paper studies hemodynamic changes after repairing congenital valvular heart disease. Two categories of Tetralogy of Fallot (TOF) and (ASD Primum) were collected from the Nasiriyah Heart Center between January 2015 and February 2022, with findings for 50 patients (28 patients with TOF & 22 patients with ASD Primum). The results showed that the spo2 value before the Surgery was low compared to its value after the Surgery, which was due to the existence of stenosis (obstruction) in the pulmonary artery; thus, the operations were undertaken to open the stenosis and return the percentage to normal. Because the patient with tetralogy of Fallot has stenosis in the pulmonary artery, compensatory found increases in the right ventricular diastolic pressure, and because the patient with tetralogy of Fallot has stenosis in the pulmonary artery, the PG value before the operation is more significant than after the operation. It was also discovered that the pG is exceptionally high due to stenosis (obstruction) in the pulmonary artery, which causes a drop in spo2. The findings demonstrated a link between age and MR before Surgery, with all patients between the ages of 2 and 47 suffering from Fatigue and restlessness. However, +++ denotes exhaustion and shortness of breath while not under stress, but ++ denotes Fatigue and shortness of breath when under normal stress.
