Summary
The Twinal 30 Lem/CCS VDD pacing system demonstrated excellent performance in 514 patients with advanced atrioventricular block. This single-lead system ensured stable atrioventricular synchrony with a low complication rate over a mean 15.2-month follow-up.
Area of Science:
- Cardiology
- Biomedical Engineering
- Medical Devices
Background:
- Advanced atrioventricular (AV) block necessitates pacing solutions.
- Single-lead VDD pacing systems offer a less invasive approach.
- Evaluating long-term performance of VDD systems is crucial.
Purpose of the Study:
- To assess the efficacy and safety of the Twinal 30 Lem/CCS VDD pacing system.
- To evaluate system performance and complication rates in patients with AV block.
- To analyze long-term AV synchrony and sensing capabilities.
Main Methods:
- A multicenter study involving 514 patients with advanced AV block.
- Implantation of the Twinal 30 Lem/CCS single-lead VDD pacing system.
- Comprehensive follow-up including X-rays, telemetry, electrogram analysis, and stress tests.
Main Results:
- Excellent system performance with 93.5% of patients paced in VDD mode.
- Stable atrioventricular synchrony and infrequent myopotential interference.
- Low rates of chronic atrial fibrillation, loss of atrial sensing, and system replacement.
Conclusions:
- The Twinal 30 Lem/CCS VDD pacing system shows excellent performance and safety.
- The system provides stable AV synchrony and a low complication rate.
- This VDD pacing system is a reliable option for patients with AV block and normal sinoatrial function.
