Feasibility assessment of Atrial Septal Defect by 3D echocardiographic virtual endoscopy

Congenital heart disease is the most common cause of death in infants. Three-dimensional echocardiography may provide reliable information than two-dimensional methods. The purpose of the study was attempted to evaluate the feasibility and accuracy of the 3D echocardiographic virtual endoscopy in Atrial Septal Defect (ASD). An improved fuzzy C-means clustering algorithm brFCM was adopted to accelerate the speed of the FCM algorithm, as well as the equivalent calculation results of the traditional method. The minimum, maximum diameter and are of ASD measured by VE were correlated well measured data. (r>;0.95, P<;0.01) In conclusion, 3DE IESS is a new technique in the field of measurement of ASD in congenital heart disease.
