In this chapter, the 2D, color Doppler and four dimensional (4D) features of major right heart
abnormalities are described. In particular, the echocardiographic views on which the various lesions are present
are reported. The diagnostic role of 4D echocardiography in allowing a spatial demonstration of the defects with
the possibility of getting new views into the heart is outlined. Videos of major diagnostic features are also
provided, to facilitate the understanding of the text.
