Assessment of atrial septal defect morphology by transthoracic three dimensional echocardiography using standard grey scale and Doppler myocardial imaging techniques: comparison with magnetic resonance imaging and intraoperative findings

摘要

Conclusions-Transthoracic three dimen- sional imaging using both GSI and DMI accurately displayed the varying mor- phology, dimensions, and spatial relations of ASD. However, DMI was a more effective technique than GSI in describing ASD morphology in adults. Objective-To determine whether trans- Thoracic three dimensional echocardio- Graphy is an accurate non-invasive Technique for defining the morphology of Atrial septal defects (ASD). Methods-In 34 patients with secundum ASD, mean (SD) age 20 (17) years (14 Male, 20 female), the measurements ob- Tained from three dimensional echocardio- Graphy were compared to those obtained From magnetic resonance imaging (MRI) Or surgery.
