Optimization of coronary sinus lead position in cardiac resynchronization therapy guided by three dimensional Echocardiography

ABSTRACT

Background: Cardiac resynchronization therapy [CRT] is now an established effective treatment for patients with advanced heart failure. One approach to improve CRT outcome may be determination of the degree of dsynchrony before CRT as a predictor for CRT response. Conversely, the focus may be on an improved positioning of CRT left ventricular [LV] lead
