Actual (reported)Cardiac pacing is the only effective treatment for symptomatic bradycardia. The right ventricular apex (RVA) has become the most frequently used ventricular pacing site. However, RVA pacing has been shown to cause left ventricular (LV) dyssynchrony wich can lead to LV dysfunction and development of heart failure. Recent studies in animals have demonstrated that pacing at the LV septum induces significantly less ventricular dyssynchrony than RVA pacing and is able to improve LV function to a similar degree as biventricular (BiV) pacing. In addition it was shown that a LV septum lead can be placed permanently by driving a lead with extended helix from the RV side through the inter-ventricular septum into the LV endocardial layer. This was shown to be a feasible and safe procedure and lead stability was shown during four months of follow-up in otherwise healthy and active canines. LV septum pacing may therefore be a good treatment alternative in patients with symptomatic bradycardia, as well as patients with an indication for cardiac resynchronization therapy (CRT). The purpose of this study is to translate the findings from preclinical studies to the clinical situation by investigating the feasibility, long-term lead stability and safety of LV septum pacing by transvenous approach through the inter-ventricular septum in patients.

Actual (reported)Number of successful LV septum lead implantations
LV septum lead implantation is considered successful if the lead can be placed in the endocardial LV septum and adequate and stable sensing and pacing tresholds are achieved.
Baseline and 6 months
Change in sensing values, pacing threshold and lead impedance
Maintenance of stable lead function is determined by assessment of change in the electrical parameters: sensing value, pacing threshold and lead impedance at baseline versus 6 months follow-up.
Baseline and 6 months
Number of participants with procedure or lead related adverse events
The number of participant with and the kind of procedure- or lead related complications are assessed at the time of the procedure and up to 6 months after lead implantation. Special attention is given to the presence of perforation or rupture of the inter-ventricular septum or free wall, pericardial effusion, thrombosis, heart rhythm disturbances, conduction disturbances, and lead-/screw dislocation/-fracture.
Patients with sinus node dysfunction and structurally normal hearts
Patients with an indication for CRT (heart failure with an LVEF \<35% and LBBB)
A left ventricular septum pacing lead is permanently placed by introducing a custom lead with extended helix transvenously and, after positioning it against the RV septum, driving it through the inter-ventricular septum into the LV endocardial layer.
