[Mono and bidimensional echocardiographic control in patients surgically treated by abdominal apical conduit (author's transl)].

Creation of a double outlet left ventricle by means of an apical conduit may solve the problems related to left ventricular outflow tract obstructions which are not amenaable to conventional surgical management. Searching a diagnostic method easily applicable, repeatable and reliable, the results obtained with serial echocardiographic controls have been evaluated. This technique has shown to be of great value in answering several hemodynamic questions. An echocardiographic protocol has been developed for the follow-up of these patients.
