OBJECTIVE: To describe the morphological features of congenital heart defects and their spatial orientations to the neighboring structures in special two-dimensional echocardiographic views.
METHODS: Conventional two-dimensional echocardiographic sections were obtained in 45 patients with atrial septal defect (ASD) and 15 with ventricular septal defect (VSD) before the en face imaging, a special echocardiographic view, was performed using a transthoracic probe for morphological characterization of the ASD and VSD. En face views of the secundum ASD and perimembranous and outflow tract or doubly committed subarterial VSD were imaged on the interatrial septal section and inflow and outflow interventricular septal section at parasternal or apical position, respectively.
RESULTS: The special echocardiographic section provided en face plane views of the congenital heart defects in 35/43 (81%) of secundum ASD and 10/15 (67%) of VSD patients, and allowed full assessment of their size, shape, circumference and spatial orientations to the neighboring structures, showing also the relationship between two or multiple defects.
CONCLUSION: The special transthoracic two-dimensional echocardiography not only displays the morphological features of ASD and VSD, but also provides additional information for making clinical decisions.
