Congenital aortic valve stenosis occurs due to thickening of the valve and commissural splicing. The prevalence of aortic stenosis is 2.4 per 10.000 live births, with male to female ratio of 3-4:1. In most cases, this defect is associated with bicuspid aortic valve. Associative structural heart abnormalities are registered in 20% of patients (persistent ductusarteriosus, coarctation, ventricular septal defect, etc). Prognosis is determined by the degree of stenosis, which depend on the transvalvular pressure gradient can be mild (<50 mm Hg), moderate (50-75 mm Hg) and severe (>75 mm Hg). There are two clinical forms of the disease: classical form (90% of patients) and neonatal critical congenital valvular aortic stenosis (10% of patients). One third of patients needs treatment, either percutaneous transcatheter balloon dilatation or surgical commissurotomy. These interventions prevent progressive heart dysfunction, and treated children have long-term reintervention-free survival. There is limited number of well-designed long-term studies thatpermits appropriate comparison of balloon dilation and surgical treatment. Therefore, there still is no consensus concerning the initial approach in patients with aortic stenosis. In the previous reports both comparable results and much more favorablesurgical results were presented. Our 26.5 years experience in treating 62 not critical aortic stenosis patients, out of newborn period, showed very comparable both early and late follow up resultsafter balloon dilation and surgical commissurotomy. Additional studies on this topic are required for establishing consensus about the initial approach.
Sergej Prijic completed medical school at the University of Belgrade (Serbia), and pediatric training at the Mother and Child Health Institute of Serbia (with ?summa cum laude? distinction). He finished his M.Sc. with highest score in the class, and his Ph.D. is being developed. He has 12 years experience in treating pediatric patients. His area of special interest is pediatric cardiology. He won the Certificate for Academic Excellence in recognition of best participant on theInternational Pediatric Cardiology Seminar 2012 (Salzburg, Austria) covered by Children?s Hospital of Philadelphia. He successfully completed Visiting Scholar Program in the Texas Children?s Hospital (Houston, USA), and observership in the Heidelberg University Children?s Hospital (Germany). In addition, he wasa volunteer pediatric cardiologist during the medical mission trip in Kharkov (Ukraine) organized by International Children?s Heart Foundation (Memphis, USA). He has published 84 papers, of which lot in reputed journals including Circulation . He is married and hastwo children
