The RV lead position, either RVA or RVHS appears to make no difference in the response to CRT but the LV lead placement play a vital role.9,30 The latest activated regions of LV or areas without transmural myocardial scar for an optimal CRT are preferred. Currently, data demonstrate that no significant difference of clinical outcomes in posterior, anterior, and lateral LV lead position was found, while the ideal pacing site of the LV should be avoided in the apex position as suggested in COMPANION trial and MADIT-CRT trial. And dual-site LV CRT, which is a new technique, is also still in progress and we are looking forward to getting more updates from that.

Cardiac resynchronization therapy (CRT) has revolutionized the care of the patients with heart failure with reduced ejection fraction and electrical dyssynchrony. The current guidelines for patient selection include measurement of left ventricular systolic function, QRS duration and morphology, and functional classification. Despite consistent and increasing evidence supporting CRT use in appropriate patients, CRT has been underutilized. Notwithstanding the heterogeneous definitions of non-response, more than one-third of patients demonstrate a lack of echocardiographic reverse remodeling or poor clinical outcome following CRT. Since the causes of this non-response are multifactorial, it will require multidisciplinary efforts to overcome including optimal patient selection, procedural strategies, as well as optimizing post-implant care in patients undergoing CRT. The innovations of novel pacing approaches combined with advanced imaging technologies may eventually offer a personalized CRT system uniquely tailored to each patient's dyssynchrony signature.
