Implication

DC shock AV junction ablation achieved block in this series; leaves open its durability and risks versus surgery in refractory SVT.

Key Points

To evaluate the effectiveness and safety of catheter-induced ablation in controlling refractory supraventricular arrhythmias.
Five patients underwent catheter ablation involving DC shocks to the His bundle.
Patients had a history of refractory supraventricular tachycardia resistant to drugs.
Follow-up intervals ranged from four to 12 months post-procedure.
All patients achieved complete atrioventricular block.
One patient died suddenly six weeks after treatment.
Mild elevations in creatine phosphokinase MB were observed without hemodynamic evidence of tricuspid insufficiency.

Does catheter-induced ablation of the AV junction using DC shocks produce complete AV block in patients with refractory supraventricular tachycardia?

Population

5 patients with recurrent bouts of supraventricular tachycardia resistant or intolerant to both conventional and experimental drugs

Intervention

Delivery of DC shocks to an electrode catheter positioned adjacent to the His bundle (catheter-induced ablation of the atrioventricular junction)

Outcome

Complete atrioventricular (AV) blockhard clinical

Catheter-induced DC shock ablation of the His bundle successfully produced complete AV block in patients with refractory supraventricular tachycardia, demonstrating early feasibility of a percutaneous alternative to open-heart surgical ablation.

Melvin M. Scheinman (1982) conducted a case report in Refractory supraventricular tachycardia (n=5). Catheter-induced ablation of the atrioventricular junction (DC shocks) was evaluated on Complete atrioventricular (AV) block. Catheter-induced ablation of the atrioventricular junction using DC shocks produced complete AV block in 100% (5/5) of patients with refractory supraventricular tachycardia.
