Comprehensive 2-D echocardiographic examination of congenital heart defects (CHD), most of which are complex, often requires visualization of the cardiac structures in not only conventional imaging planes but also in many orthogonal and off-axis planes. A transducer that delivers images in multiple orientations from a fixed site would be of value in children. We explored the potential of a new prototype 5.0/3.7 MHz transthoracic multiplane transducer (MPTTE) which provides a continuous sweep of the imaging plane in a 180 degree arc without transducer movement. The diagnostic information derived by from additional imaging planes by MPTTE was compared to that obtained with conventional 2DE planes in 21 children with a variety of CHD. Using the MPTTE continuous sweeps were performed from different acoustic windows. 2 observers independently evaluated the studies. In 3/21 pts (14%): new lesions were identified MPTEE that were missed by conventional 2DE; they include TV involvement in a repaired VSD, additional muscular VSDs and eccentric subaortic obstruction. In 12/21 (57%), there was enhanced delineation of pathology; these include better definition of muscular VSDs, subaortic membranes, continuity of the PAs in a variety of CHDs, relative position of the A-V valve in unbalanced A-V septal defects, RV morphology in pulmonary atresia, regurgitant jets and their mechanism and PDAs. We conclude that transthoracic multiplanar imaging enhances the versatility of echocardiography and is likely to become the state-of-the art in pediatric cardiac ultrasound.
