Echocardiography for the management of patients with biventricular pacing: Possible roles in cardiac resynchronization therapy implementation.

Echocardiography for the management of patients with biventricular pacing: Possible roles in cardiac resynchronization therapy implementation. Hellenic J Cardiol. 2018 Feb 13;: Authors: Poulidakis E, Aggeli C, Kappos K, Manolis AS, Sideris S, Gatzoulis K, Oikonomou E, Tousoulis D Abstract Cardiac Resynchronization Therapy (CRT) is an established therapeutic option for the subset of patients with heart failure (HF), reduced ejection fraction (EF) and dyssynchrony evidenced by electrocardiography. Benefit from CRT has been proven in many clinical trials, yet a sizeable proportion of these patients with wide QRS do not respond to this intervention, despite the updated practice guidelines. Several echocardiographic indices, targeting mechanical rather than electrical dyssynchrony, have been suggested to address this issue, but research so far has not succeeded in providing a single and simple measurement with adequate sensitivity and specificity for identification of responders. While there is still ongoing research in this field, echocardiography proves helpful in other aspects of CRT implementation, such as site selection for left ventricular (LV) lead pacing and optimization of pacing parameters during follow up visits.
