Analysis of Atrial and Ventricular Performance by Tissue Doppler Imaging in Patients with Atrial Septal Defects before and after Surgical and Catheter Closure

Abstract

In contrast to surgery, transcatheter closure of atrial septal defect preserves atrial and right ventricular function. Tissue Doppler derived strain rate can be applied to provide quantitative analysis of regional atrial and ventricular performance.
