[Quantitative angiocardiography of the complete atrioventricular canal].
23 patients with common atrioventricular canal were studied, seven with associated pulmonary stenosis, using methods of quantitative angiocardiographie (ventricular volume, ejection fraction, wall motion, Emas as an index of contractility). Left and right ventricular end-diastolic volume is increased and related to the Qp/Qs ratio. Pulmonary stenosis has limitant effect on end-diastolic volume, likely by variations of right ventricular compliance. Ejection fraction tended to normal values or is lightly reduced, but the study of wall motion demonstrated a severe hypokinesis of diaphraguscolar septum and of the diaphragmatic region; also the contractility is depressed. Finally were reported some observations about the haemodynamics behaviour of the common atrioventricular canal in the early post-surgical stage.
