End-Diastolic Wall Thickness as a Predictor of Reverse Remodelling After Cardiac Resynchronization Therapy: A Two-Dimensional Echocardiographic Study

The extent of ventricular segments with EDWT < 6 mm assessed by 2-D echocardiography is an important factor influencing response to CRT at follow-up. GSA may represent an essential simple adjunct to mechanical asynchrony to better select patients suitable for CRT.
