Initial Clinical Experience with a New Self‐Retaining Left Ventricular Lead for Permanent Left Ventricular Pacing
Key result
A new self-retaining left ventricular lead was successfully implanted in 85% (11/13) of patients with sick sinus syndrome, with no postprocedural dislodgment up to 6 months.

Does a new self-retaining left ventricular lead provide safe and reliable permanent LV pacing in patients with sick sinus syndrome?
Population
13 patients (4 men, 9 women, mean age 71 +/- 13 years) with sick sinus syndrome.

Implication
May support LV lead feasibility in sick sinus syndrome; leaves open efficacy versus standard leads in larger trials.

Type
Observational (n=13)
Structured PICO
Does a new self-retaining left ventricular lead provide safe and reliable permanent LV pacing in patients with sick sinus syndrome?
P
Population
13 patients with sick sinus syndrome (mean age 71 years, 69% female) evaluated for permanent left ventricular pacing via the coronary sinus and followed for up to 6 months.
E
Exposure
A new self-retaining left ventricular lead (75-cm-long, 4.8-Fr, unipolar ventricular lead with a distal portion preshaped in an S curve) for permanent LV pacing via the coronary sinus.
O
Outcome
Efficacy and stability for permanent LV pacing (implant success, fluoroscopy time, lead position, R wave amplitude, LV pacing threshold, lead impedance) at implant, predischarge, and at 1, 3, and 6 months of follow-up.surrogate
A new self-retaining left ventricular lead offers safe and reliable permanent LV pacing via the coronary sinus with an 85% implant success rate and stable parameters over 6 months.

Tse et al. (2000) conducted an observational in Sick sinus syndrome (n=13). New self-retaining left ventricular lead was evaluated on Successful implantation. A new self-retaining left ventricular lead was successfully implanted in 85% (11/13) of patients with sick sinus syndrome, with no postprocedural dislodgment up to 6 months.
