Atrioventricular junction symmetry in children with different anatomical variants of atrioventricular communication: echocardiographic parameters

Abstract

Atrioventricular (AVC) communication is a group of congenital heart diseases with common atrioventricular connection. The symmetry of the connection and, as a result, anatomy and physiology of atrio-ventricular infl ow plays the key role in possibility of double-ventricle correction in this anomaly. Nowadays there is tendency to mix new concepts with described parameters that characterize AVC in one whole guidelines. The ultimate pathway has to be the one that minimizes morbidity and mortality outcomes. In the article author present the correlation between main cardiac echocardiography measurements, that characterize the symmetry of atrioventriculat connection (atrioventricular valves indexes, left ventricle inflow index, inflow angle between left and right ventricles) and their correlation with size of common atrio-ventricular valve and ventricle’s size. Key words: unbalanced atrioventricular communication, atrioventricular valve index, left ventricular flow index, inflow angle between right and left ventricles, ventricular cavity index.
