Abstract/OtherAbstract:
OBJECTIVE: The aim of this study is to assess the diagnostic role of 4D ultrasound in cardiosplenic syndromes. In particular, the objective is to define the diagnostic accuracy of four-dimensional ultrasound (STIC-SonoAVC) in the identification of atrial morphology in 22 cases of cardiosplenic syndrome referred to our center for diagnosis and management over the last 5 years. METHODS: This is a retrospective investigation including 22 fetuses with cardiosplenic syndromes seen at our institution since 2004. As control groups, 10 normals, 5 cases of non-isomeric atrio-ventricular septal defect and 5 other congenital heart diseases were analysed. For all, one or more cardiac volume datasets were available for offline analysis. Two-dimensional and four-dimensional echocardiography was carried out in all cases at the time of diagnosis using high quality 3D equipment (Voluson 730 Expert and E8/E9, Kretztechnik, Zipf, Austria for General Electrics). The dedicated software (4D-viewer 10.0) was used to assess chamber morphology by means of the SonoAVC technique, which allows to create casts of hollow structures. Two different operators used the software. The first one made all the steps up to the confirmation of the Region Of Interest (ROI) box. Once the ROI was set, the second operator took its turn in rendering the cardiac chambers by use of the SonoAVC technique, being blinded to the diagnosis of left or right isomerism. The same operator then employed the rendered image to subjectively assess atrial morphology. RESULTS: Suitable rendered images could be reproduced in 40/42 cases, in which advanced (34 weeks) and early (13 weeks) gestational age made the obtainment of adequate rendered images impossible. In the remaining 20 cases, atrial morphology was correctly identified by looking at the rendered images. CONCLUSION: Four-dimensional ultrasound with Sono-AVC rendering allows a correct identification of atrial morphology in all cases of cardiosplenic syndromes in which an adequate cardiac volume dataset was available for analysis.
