All but three had discordant ventriculoarterial connections or double outlet right ventricle. Data suitable for reconstruction was acquired with transthoracic scanning. Right and left ventricular volumes were calculated in the 3D dataset.<\/jats:p><\/jats:sec><jats:sec id=\"S104795110000888X_sec03\" sec-type=\"results\"><jats:title>Results<\/jats:title><jats:p>3D echocardiography proved capable of defining the exact degree of straddling by imaging theproportion of tension apparatus attached to either side of the ventricular septum. It was able also to display the atrioventricular junction \u201cen face\u201d, thus permitting identification of the precise site of insertion of the muscular ventricular septum relative to the atrioventricular junction. This made it possiblefirst, to calculate the degree of valvar override, and second, to predict the location of the penetrating atrioventricular bundle. End-diastolic volume of the right ventricle in those with straddling tricuspid valves was 73 (61\u201383)% of normal, and, of the left ventricle in those with mitral valvar straddling 71 (40\u201097)% of normal.<\/jats:p><\/jats:sec><jats:sec id=\"S104795110000888X_sec04\" sec-type=\"conclusion\"><jats:title>Conclusions<\/jats:title><jats:p>3D echocardiography can aid in planning the optimal surgical procedure in patients with straddling or overrriding atrioventricular valves, as it provides diagnostic information superiorto standard crosssectional techniques.
