Two Different Lead Implantation Techniques for Multisite Biventricular Pacemakers

Multisite biventricular pacing has recently been proposed for treating patients with drugrefractory heart failure associating severe left ventricular systolic dysfunction and intraventricular conduction delay. Some difficulties may be seen during implantation depending on the characteristics of the technique and the patients. In this paper, we report the difficulties of lead implantation and the alternative methods we used during multisite biventricular pacemaker implantation in two cases.
