TOF is a ventricular stenosis (VSD), overriding an aorta and right-wing ventricular hypertrophy (RV). 3.36 percent of all congenital heart disorders, are the most prevalent congenital cardiac cyanotic, is the most common congenital cardiac cyanotic disorder. After the cardio-pulmonary bypass was introduced in 1953 it was possible to fix the surgical TOF, and since 70s operating results have improved significantly. At now, over 20–30 years of TOF repairs, the survival probability is 85–90% which is regarded good. Residual pulmonary stenosis, PR and arrytmia are all factors that affect survival after surgical repair when reparation has been completed (that is to say before 1970). Large structures like aorta, lower vein cava, and oesophagus were extended by the triple balloon. This three-ballon approach has been utilized by Gaylord et al to examine balloon geometrically in diameter. Based on their findings, two balls with a diameter of 12 mm and one ball with a diameter of 15mm might concurrently be inflated with the aim of reaching a diameter of around 26mm. Microindel et al. stated that the long-term success rate was limited, and reinterference is often essential after balloon valvulation procedure in RV / pulmonary artery patients with pinnacle-to- peak gradients of at least 36 mmHg. The RV-pulmonary gradient was 13 mmHg in the current patient after therapy and showed a beneficial attempt to lower pressure. The patient had a positive effect of RV-to-pulmonary arthritis. Following treatment, no increased chronic phase pressure was noticed and its subjective symptoms were subsequently relieved. Hence, we consider that valvular plastics are a potential strategy to improve the chronic forecast of pulmonary stenosis.
