Three dimensional (3D) echocardiography represents a major paradigm shift in medical ultrasound
imaging. As opposed to reconstructed 3D echocardiography which is based on a series of two dimensional images, the
revolutionary development of the two dimensional (2D) matrix phased array transducer permits true real time live 3D
imaging of the fetal heart. Preliminary experience has demonstrated that real time/live 3D echocardiography is not
only feasible in assessing the fetal cardiac anomalies, it also permits unique comprehensive views of the fetal
heart that are unattainable with 2D echocardiography. With further evolution of the technology, and appropriate
education and training RT3D echocardiography may evolve as a powerful supplement to conventional 2D
echocardiography.
