Transthoracic real-time three-dimensional echocardiography using the rotational scanning approach for data acquisition.

Abstract

Transthoracic real-time three-dimensional echocardiography using the rational scanning approach for data acquisition became a feasible modality for cardiac imaging during the last 4 years. Several attempts for reconstruction of the heart have been made using different methods. In this study we evaluate the data acquisition using the rotational approach from the transthoracic window. Thirty-five children with congenital heart disease were enrolled in the study. All of them underwent complete two-dimensional and Doppler echocardiogram followed by three-dimensional reconstruction using rotational image acquisition. The rotational approach enabled us to acquire good data from subcostal, apical, and suprasternal notch positions by rotating the transducer from 0 degrees-180 degrees. Novel views of the atrioventricular valve, semilunar valve, atrial, and ventricular septi were established by spatial plane imaging from the three-dimensional echocardiography. This reconstruction enables spatial imaging of cardiac structures and deficiencies. Three-dimensional echocardiography will enhance the understanding of complex congenital heart disease.
