Validity of Color Coded Tissue Doppler Imaging in the Assessment of Interventricular Septal Motion in Adult Patients with Atrial Septal Defect

Abstract

Background: Atrial septal defect (ASD) is one of the most widely recognized cardiac congenital abnormalities in adulthood. Atrial septal defect is characterized by an inter-atrial septum defect that allows the pulmonary venous return from the left atrium to pass directly to the right atrium. Paradoxical septal motion is mainly detected by two-dimensional and M-mode echocardiography. The recently introduced Doppler tissue imaging (TDI) echocardiographic modality has been used in many
clinical situations, including ventricle wall movement determination.
