Why the study?
Does the presence of two ventricular leads compared to one ventricular lead worsen right ventricular hemodynamics in patients with permanent pacemakers?
Population
50 patients with permanent pacemakers, mean age 61 years.
Comparison
Two ventricular leads vs One ventricular lead
Design
Cohort
Follow-up
2 years after lead implantation

Abandoned ventricular leads may worsen tricuspid insufficiency without hemodynamic effects; leaves open whether extraction improves long-term outcomes.
Does the presence of two ventricular leads compared to one ventricular lead worsen right ventricular hemodynamics in patients with permanent pacemakers?
Leaving an abandoned ventricular lead in situ increases the severity of tricuspid insufficiency but does not significantly impact overall right ventricular hemodynamics at 2 years.
