Key result
J-shaped atrial leads show similar overall lead-related complications to straight leads despite differing specific types.
Why the study?
Does a J-shaped atrial lead improve long-term performance and reduce complications compared to a straight atrial lead in patients requiring atrial pacing?
Population
208 consecutive patients requiring atrial pacing leads
Comparison
J-shaped atrial lead with active fixation vs Straight atrial lead with active fixation
Design
RCT, randomized
Follow-up

Clinicians may select either atrial lead shape; confirms long-term equivalence in overall complications from this RCT.
RCT (n=208)
Does a J-shaped atrial lead improve long-term performance and reduce complications compared to a straight atrial lead in patients requiring atrial pacing?
Absolute Event Rate: 6% vs 9%
p-value: p=0.45
J-shaped and straight active-fixation atrial leads have comparable overall complication rates at 5 years, but straight leads are more prone to dislodgment while J-shaped leads have more electrical malfunctions.
Luria et al. (2005) conducted an RCT in Patients requiring atrial pacing leads (n=208). J-shaped atrial leads (Medtronic 4568 JL) vs. Straight atrial leads (Medtronic 4068 SL) was evaluated on Lead-related complications (p=0.45). J-shaped atrial leads resulted in similar overall lead-related complications compared to straight leads (6% vs 9%, P=0.45) over 5 years, though specific complication types differed.
