Introduction: Anatomical comprehension of congenital cardiac diseases by 2D echocardiography is occasionally very difficult. 3D echocardiography provides a more spatial anatomical information avoiding the need of two-dimensional reconstruction.
Methods: Of the 271 cases studied 80 were foetal and 191 patients. In all cases, 2D and 3D echocardiography was performed (Sonos 7500 with matrix probe). Four modes of 3D imaging were used.
Results: 3D echocardiography gave an accurate description of the size, form and wedges of septals defects. In atrioventricular septal defects and mitral anomalies, 3D echocardiography was useful for the assessment of dynamic valve morphology and mechanisms of regurgitation. In foetal screening the segmentary heart study was carried out from a single acoustic window.
Conclusions: 3D real time echocardiography is a feasible, easy and rapid technique. It provides anatomical and functional details needed for an accurate comprehension of congenital cardiac diseases. In foetal screening, it provides an easier segmentary analysis of the entire foetal heart.
