[A left intraventricular thrombus in an adolescent. Its relationship to the anticardiolipin antibody syndrome].

The authors are going to present the clinical case of a 14-years-old female patient who has got an anticardiolipin antibodies syndrome, a theme to which they add some ideas concerning physiopathology and diagnosis criteria. They'd like to emphasise the echocardiographic observation, which allowed them to find out and follow the evolution of a left sided intraventricular thrombus, the real cause for the systemic thrombosis.
