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.

10.Atrioventricular intrinsic conduction and cardiac resynchronization therapy.
Chinese Medical Journal 2011;124(3):436-439
Cardiac resynchronization therapy (CRT) is a major breakthrough in therapy for patients with advanced congestive heart failure, however, a number of key clinical research questions remain, perhaps most importantly the issue of why apparently suitable patients do not respond to CRT. These issues are also relevant to patients who do respond to CRT as potentially their response might be further increased. Though patients do not respond to CRT because of many known postulated reasons, we review the importance of maintaining atrioventricular intrinsic conduction during CRT in this paper, which maybe is one of methods to reduce the rates of non-response to CRT.
