Implant failures and revisions warrant caution; leaves open the viability of S-shaped leads pending prospective validation.
Does an S-shaped non-steroid unipolar lead provide stable pacing and sensing performance in patients with severe congestive heart failure?
The S-shaped unipolar lead provided stable long-term pacing thresholds, though it was associated with notable rates of implantation failure and acute dislodgement requiring revision.
