Use of an active-fixation coronary sinus lead to implant a biventricular pacemaker via the femoral vein

Cardiac resynchronization therapy, which involves the placement of a pacing lead in the right atrium and in each ventricle, is effective in treating heart failure that is caused by left bundle branch block and cardiomyopathy. The left ventricular lead is usually placed into a lateral branch of the coronary sinus via the subclavian route. When the subclavian route is unavailable, insertion of a standard, passive-fixation coronary sinus lead via the femoral approach is feasible; however, the likelihood of subsequent dislodgment is high. Herein, we describe the placement of a novel, self-retaining, active-fixation coronary sinus lead--the Attain StarFix Model 4195 OTW Lead--in an elderly heart-failure patient, via the femoral approach. We believe that this is the 1st report of this procedure.
