[Anatomico-echocardiographic comparisons of heart structures. Additional diagnostic cross-sections]

Possibilities of two-dimensional echocardiography using a number of additional cross-sections (right chambers sectioned longitudinally, four-chamber epigastric view, longitudinal cross-section of aortal arc) have been investigated. Heart structures were identified on the basis of comparisons with anatomical cross-sections of the heart in the preset planes. The study is based on sections from 34 hearts and findings of 46 echocardiographic investigations in normal subjects. Some methodological procedures for obtaining such echocardiograms are specified.
