Key result
Right ventricular septal pacing was associated with significantly lower rates of death and heart failure hospitalization at 2 years compared to right apical pacing (2% vs 19%; p<0.05).
Why the study?
Does right ventricular septal (RVS) pacing reduce death and hospitalization due to heart failure compared to right ventricular apical (RVA) pacing in patients with atrioventricular block?
Population
149 consecutive patients who underwent implantation of a dual chamber pacemaker for atrioventricular block
Comparison
Right ventricular septal (RVS) pacing vs Right ventricular apical (RVA) pacing
Design
Cohort
Follow-up
2 years

May support septal over apical RV pacing in AV block; leaves open need for RCTs to confirm benefit.

Absolute Event Rate: 2% vs 19%
p-value: p=<0.05
Right ventricular septal pacing is associated with significantly lower rates of mortality and heart failure hospitalization compared to right ventricular apical pacing over 2 years in patients with atrioventricular block.
Kikuchi et al. (2012) conducted a cohort in atrioventricular block (n=149). Right ventricular septal (RVS) pacing vs. Right ventricular apical (RVA) pacing was evaluated on Death and hospitalization due to heart failure (HF) (p=<0.05). Right ventricular septal pacing was associated with significantly lower rates of death and heart failure hospitalization at 2 years compared to right apical pacing (2% vs 19%; p<0.05).
