Short and midterm results of balloon valvuloplasty in the neonate with critical aortic stenosis

Introduction: Postnatal therapy of critical aortic stenosis aims to relief left ventricular outflow tract obstruction and to improve left ventricular function. Aim of our study is to follow up neonates with critical aortic stenosis in respect to long term results. Method: Prospective follow up of 17 neonates with critical aortic stenosis, 13 were diagnosed prenatally, 3 had previous intrauterine balloon valvuloplasty. Results: Balloon valvuloplasty (BVP) was performed in ll at the age of 1.4±3.6 days and a weight of 2.8±0.77kg. Left ventricular contractility was below 15% in 12 neonates. In 16/17 neonates, BVP c…
