Implication

Demonstrates feasibility of transcatheter His-bundle ablation; leaves open long-term safety and efficacy in larger cohorts.

Structured PICO

Does delivery of DC shocks to an electrode catheter positioned adjacent to the His bundle produce complete AV block in patients with refractory supraventricular tachycardia?

P
Population
5 patients with recurrent bouts of supraventricular tachycardia resistant or intolerant to both conventional and experimental drugs
I
Intervention
Delivery of DC shocks to an electrode catheter positioned adjacent to the His bundle (catheter-induced ablation of the atrioventricular junction)
O
Outcome
Complete atrioventricular (AV) blocksurrogate

Catheter-induced DC shock ablation of the His bundle successfully produced complete AV block in patients with refractory SVT, offering a potential alternative to open-heart surgery.
