BIOTRONIK has an unsurpassed legacy of providing quality therapy solutions. We cultivate expertise in understanding the challenges electrophysiologists face so that we can provide state-of-the-art technology with precise performance and highly reliable results. Implantation procedures for cardiac resynchronization therapy (CRT) remain challenging with regard to left ventricular (LV) lead delivery reaching the optimal lead position Presence of extra-cardiac stimulation and/or non-viable myocardial tissue may require repositioning of the lead extend implantation and fluoroscopic time The VisionWire helps to find the most optimal LV lead fixation site before inserting the lead! Pre- or intraoperative stimulation of left ventricle using an insulated 0.01.4” guide wire in combination with standard implant module or threshold analyzer helps assessing thresholds excluding extra-cardiac stimulation identifying mechanical non-responders
