INDICATION OF INTERVENTIONAL PROCEDURE FOR ISOLATED SYNCOPAL PULMONARY STENOSIS IN ADOLESCENTS: CASE REPORTS AND REVUE OF LITERATURE.

Pulmonic stenosis refers to a dynamic or fixed anatomic obstruction flow from the right ventricle pulmonary arterial vasculature. Although most commonly diagnosed and treated in pediatric population, some patients with severe, isolated PS may be for first time as adults, represents approximately 10% of all congenital heart disease. We report cases three adolescents, who presented ER after having several episodes syncopes during exercise. The TTE showed dome-shaped valve, peak velocity between 5,3 6,8 m/s, ventricular hypertrophy dilatation. proceed balloon valvuloplasty used dilatation catheter until waisting disappeared. An echocardiography was performed day procedure, showing drop decreased In older children percutaneous is line treatment valvar irrespective symptoms. Catheter-based valvotomy recommended non-dysplastic valvular peripheral PS. Surgery sub-infundibular infundibular hypoplastic annulus, dysplastic valves, associated lesions which need surgical approach, such severe regurgitation tricuspide regurgitation. Simple can provide definitive solution avoid surgery.
