Summary
Retained pacemaker leads do not negatively impact right ventricular or tricuspid valve function long-term. Echocardiographic assessment showed no significant differences in function between patients with one or two ventricular leads.
Area of Science:
- Cardiology
- Medical Devices
Background:
- Limited data exists on the long-term effects of retained pacemaker leads.
- Right ventricular (RV) and tricuspid valve function are crucial in pacemaker patients.
Purpose of the Study:
- To investigate the long-term impact of retained ventricular leads on RV and tricuspid valve function.
- To compare outcomes in patients with one versus two retained ventricular leads.
Main Methods:
- Echocardiographic assessment of 40 patients with permanent pacemakers.
- Group I (n=18) had two ventricular leads; Group II (n=22) had one.
- Follow-up averaged 39 months (Group I) and 80 months (Group II).
Main Results:
- Group I had significantly larger lead body diameter sums than Group II.
- No significant differences were observed in chamber diameters, RV function, or valvular function between groups.
- Tricuspid regurgitation (TR) was predominantly mild in both groups.
Conclusions:
- Retained second pacemaker leads do not appear to have an additional negative effect on RV and tricuspid valve function.
- The presence of a second lead did not worsen cardiac function compared to a single lead.
