Using multiple buddy wires to facilitate left ventricular lead advancement in cardiac resynchronization therapy.
Left ventricular lead positioning is always the critical step in cardiac resynchronization therapy because of the complex anatomy of coronary sinus branches. We describe the case of a 46-year-old man with dilated cardiomyopathy and complete left bundle branch block presenting with heart failure. The placing of the left ventricular lead into the posterolateral branch was hampered by an angulated portion at the proximal branch even with the assistance of anchor wire technique and one to two additional parallel wires' support. The use of three buddy wires facilitated the advancement of the left ventricular lead.
