Electroanatomical Map of the Coronary Sinus With NavX EnSite (A) Coronary venogram of a patient undergoing cardiac resynchronization therapy implantation. (B) X-ray of final LV lead placement. (C) Coronary venous electroanatomic map during intrinsic ventricular activation together with the corresponding unipolar electrograms collected from the regions of earliest and latest activation. The coronary sinus and all side branches have been mapped. Connecting the LV lead to EnSite NavX allowed real-time visualization and navigation of the lead to the latest activated region in the electroanatomic map. Note the large difference in local depolarization between proximal and distal sites in the ALV. The proximal electrode of the quadripolar lead was positioned in the area with latest depolarization.

AIV = anterior interventricular vein; ALV = anterolateral vein; IIV = inferior interventricular vein; ILV = inferolateral vein; RA = right atrial; other abbreviations as in Figure 3.
