Live/real time three-dimensional transthoracic echocardiographic findings in an adult with complete atrioventricular septal defect.

Live/real time three-dimensional transthoracic echocardiography provided incremental value over two-dimensional transthoracic echocardiography in an adult patient with complete atrioventricular (AV) septal defect by (1) making a confident diagnosis of Rastelli type A defect, (2) providing en face view of all the five leaflets of the common AV valve, (3) diagnosing left ventricle to right atrial shunt, and (4) permitting more accurate quantitative assessment of regurgitant lesions.
