Key result
A novel steroid-eluting active fixation lead yielded an average chronic stimulation threshold of 0.19 msecs in patients with prior atrial exit block, while 3 of 15 ventricular patients had recurrences.
Why the study?
Does a novel steroid-eluting active fixation lead provide adequate chronic stimulation thresholds and prevent recurrent exit block in patients with a history of exit block?
Population
24 patients with a history of exit block (15 ventricular and 9 atrial)
Design

May support atrial use in prior exit block; leaves open ventricular durability pending randomized confirmation.

Does a novel steroid-eluting active fixation lead provide adequate chronic stimulation thresholds and prevent recurrent exit block in patients with a history of exit block?
A novel steroid-eluting active fixation lead shows encouraging chronic stimulation thresholds in patients with prior atrial exit block, but recurrent exit block remains a concern in ventricular applications.
Crossley et al. (1994) conducted an observational in Prior exit block (n=24). Steroid-eluting active fixation lead was evaluated on Lead function (chronic stimulation threshold and recurrent exit block). A novel steroid-eluting active fixation lead yielded an average chronic stimulation threshold of 0.19 msecs in patients with prior atrial exit block, while 3 of 15 ventricular patients had recurrences.
