3D Echocardiographic Evaluation of Right Ventricular Functions: A Prognostic Study in Pediatric Population with Critical Pulmonary Stenosis Undergoing Balloon Pulmonary Valvuloplasty

Abstract

Background: Critical pulmonary stenosis has been associated with severe right ventricular outflow tract obstruction (RVOTO) leading to severe right ventricular hypertrophy (RVH), impaired both systolic and diastolic functions, changes in RV shape and geometry, hence further assessment by 3D echocardiography (3D Echo) is recommended. Objective: The aim of the current work was to evaluate RV (Right Ventricle) functional indices using 3D echocardiography in infants with critical pulmonary stenosis undergoing balloon pulmonary valvuloplasty and to evaluate RV (Right ventricle) indices as follow up parameters in infants with critical pulmonary stenosis (PS). Patients and Methods: This prospective study included a total of 60 infants with critical pulmonary stenosis, their median age was 8.5 (range 2 -12) months referred for urgent balloon pulmonary valvuloplasty to Pediatric Cardiology
