Active Fixation Leads in the Distal Coronary Venous System for Left Ventricular Stimulation: A Safety and Feasibility Study

Introduction: Well positioned left sided lead implantation via the coronary venous system is central in ensuring delivery of resynchronization therapy in selected patients with heart failure. Unfortunately, many factors can negatively impact optimal positioning. Therefore, we investigated the safety and feasibility of using an active fixation lead in the distal branches of the coronary sinus for left ventricular stimulation. Methods: From May...
