Clinical Surveillance of a Tined, Bipolar, J‐Shaped, Steroid‐Eluting, Silicone‐Insulated Atrial Pacing Lead
Key result
The Medtronic 5524 atrial lead demonstrated a 0.9% rate of acute lead-related complications and no chronic complications over a median follow-up of 17.5 months.
Why the study?
Does the Medtronic 5524 atrial lead demonstrate safety and reliability in patients requiring atrial pacing?

Structured PICO
Does the Medtronic 5524 atrial lead demonstrate safety and reliability in patients requiring atrial pacing?
P
Population
558 patients implanted with the Medtronic 5524 atrial lead, followed for a median of 17.5 months.
E
Exposure
Medtronic 5524 bipolar, silicone-insulated, J-shaped, tined, steroid-eluting atrial lead
O
Outcome
Pacing thresholds at implantation, acute lead-related complications, and chronic lead-related complications or material failure over median 17.5 months follow-upsafety
The Medtronic 5524 atrial lead demonstrates excellent safety and reliability with low complication rates and stable pacing thresholds over long-term follow-up.
Cite This Study
Glikson et al. (1999) reported an observational. Medtronic 5524 atrial lead was evaluated on acute lead-related complications necessitating reoperation or electrical abandonment. The Medtronic 5524 atrial lead demonstrated a 0.9% rate of acute lead-related complications and no chronic complications over a median follow-up of 17.5 months.
