Usage of active fixation bipolar left ventricular (LV) leads represents an alternative approach to the more commonly used passive fixation quadripolar leads in cardiac resynchronization therapy (CRT). We compared a bipolar LV lead with a side screw for active fixation and passive fixation quadripolar LV leads. Sixty-two patients were before CRT implantations randomly allocated to receive a bipolar (n=31) or quadripolar (n=31) LV leads. Speckle-tracking radial strain echocardiography was used to define the LV segment with l
