Abstract:

Abstract Pulmonary artery stenosis (PAS) is a quite rare condition that can lead to incorrect diagnosis particularly in adults. PAS in childhood is frequently associated with other syndromes. However, the etiology of this pathology in adolescents and adults remains unclear. Potential problems of echocardiographic diagnosis of pulmonary artery stenosis are reviewed in this article. Retrospective analysis of 2030 protocols of echocardiography in children and adolescents revealed weak negative relationship of Vmax (on pulmonary valve in PW-mode) with age (r=–0.15; p<0.95) and moderate positive correlation of Vmax on pulmonary valve with Vmax on aortic valve (r=0.43, p<0,05). In general, mean blood flow velocity on the pulmonary valve was 1.03±0.25 m/s. First of all, it is necessary to exclude pulmonary trunk stenosis («membrane» or «couplings/strands» as a rule) if Vmax in pulmonary trunk exceeds normal values by 10% (over 1.518 m/s).
