The Detection and Assessment of Straddling and Overriding Atrioventricular Valves by Two-Dimensional Echocardiography
Part of the
Developments in Cardiovascular Medicine
book series (DICM, volume 13)
Sixteen patients with a straddling tricuspid and two with a straddling mitral valve were identified by two-dimensional echocardiography. In all but one the atrioventricular valves (AV) appeared at the same level indicating absence of the ventriculo-atrial septum.
Straddling was determined by identifying subvalvular apparatus from one AV valve in both chambers. Overriding was greater than 50% in 12, and less than 50% in 5, with one having no detectable overriding.
