Newer Echocardiographic Techniques in Cardiac Resynchronization Therapy

Publication date: December 2015 Source:Cardiac Electrophysiology Clinics, Volume 7, Issue 4 Author(s): John Gorcsan, Bhupendar TayalTeaser Echocardiographic imaging plays a major role in patient selection for cardiac resynchronization therapy (CRT). One-third of patients do not respond; there is interest in advanced echocardiographic imaging to improve response. Current guidelines favor CRT for patients with electrocardiographic (ECG) QRS width of 150 milliseconds or greater and left bundle branch block. ECG criteria are imperfect; there is interest in advanced echocardiographic imaging to improve patient selection. This discussion focuses on newer echocardiographic methods to improve patient selection, improve delivery, and identify patients at risk for poor outcomes and serious ventricular arrhythmias.
