Abstract
Introduction: Balloon Valvuloplasty is the first-line treatment for congenital valve pulmonary stenosis (PS) in children and adults.
Methods: We reported immediate results of balloon valvuloplasty in congenital pulmonary stenosis from 2014 to 2019.
Results: BPV was performed in 40 patients, the diagnosis was based on cardiac ultrasound data showing valvular dysplasia in 92% of cases, the main associated anomaly is FOP in 22.5% of cases, immediate success (defined by a peak-to-peak gradient after the DPPC of less than 50mmHg) was found in 88% of cases, allowing a significant reduction in mean peak to peak pressure among pulmonary valve from 69.65mmHg to 30.19mmHg. After BV 11% of patients maintained a high gradient, the independent predictive factors were valvular dysplasia and the small diameter of the ring an immediate post procedural infundibular reaction was noted in 25% of cases mainly related to valvular dysplasia. The mortality of the procedure was zero and morbidity was low. mild pulmonary regurgitation was found in all patients.
Conclusion: PV has been established as the treatment of choice for valvular PR with few complications. Following its satisfactory immediate results, the indications quickly extended to critical pulmonary stenosis in newborns and late discovery forms in adults.
