In patients with volume overload due to atrial septal defect (ASD) and Doppler tissue imaging E'/A' <1 at baseline, right ventricular (RV) myocardial velocities show load independence after closure with a device. Conversely, in patients with ASD with basal E'/A' >1, regional velocities are load-dependent and positively correlate with RV dimension. Because RV Doppler tissue imaging velocities are still in the normal range 1 month after ASD closure, cardiac function does not seem to be affected by the presence of the occluder device.
