A multiple element ultrasound system has been developed which provides moving cross-sectional images of the heart. Unique features are the capacity to display substantial segments of cardiac structures and to show them in continuous, real-time motion. Two standard transducer positions have been established of which one produces images of a sagittal cardiac cross-section in the plane of the septum and the other a horizontal section across the ventricles. Studies with satisfactory detail were possible in most children and in two-thirds of adults investigated. Clinical information may be obtained regarding anatomic relationships of major structures in congenital heart disease and about cardiac valve motion and thickening or calcification in valvular heart disease. Measurements of aortic root dimensions are accurate when compared with angiography. Ventricular dimensional measurements are not validated as yet. The Multiscan concept is still under development, but shows promise of significantly expanding the capabilities of clinical echocardiography.
