[Echocardiographic studies with a multiscanner apparatus].

This technique aims at obtaining a dynamic bi-dimensional image of the cardiac structures, which can be directly registered on videotape and photographed with Polaroid cameras. It is particularly useful -- in as much as it gives characteristic images -- for obstructive and non-obstructive hypertrophic myocardiopathies, in exudative pericarditis, in tetralogy of Fallot and mitralic stenosis.
