Abstract:
Objective To evaluate the ventricula r septal defect qualitatively and quantitatively by real-time three-dimensional echocardiography (RT-3DE).Methods RT-3DE were performed in 10 pig hearts with 22 ventricular septal defects in multiple orientations and cross sections. The diameters and areas of ventricular septal defects were measured both in RT-3DE and anatomic view. Echo images and parameters derived by RT-3DE were compared with anatomic view. Results Technically satisfactory RT-3DE images were obtained in all preparations. The location, size, morphology, and spatial relationships with surrounding cardiac structure of ventricular septal defects were displayed instantly. No significant differences were found between RT-3DE and anatomic measurements. Conclusions RT-3DE has advantages of instantly displaying the ventricular septal defects in anyplane and has important surgical and interventional implications.
