Biotronik reports positive data from catheter ablation trial for atrial fibrillation

Biotronik has announced new clinical trial data showing the effectiveness of catheter ablation of atrial fibrillation as a first-line treatment for people with heart failure.

Data from the CASTLE-AF study have been presented at the European Society of Cardiology Congress showing significant reductions in mortality and heart failure events with catheter ablation compared to pharmacological therapy.

A 38 percent reduction in all-cause mortality and hospitalisation rates for worsening heart failure was observed when patients with atrial fibrillation received catheter ablation instead of pharmacological treatments recommended under current guidelines.

This was the world's largest randomised clinical study of catheter ablation in this patient group, with a total of 398 patients enrolled across 33 sites in Europe, Australia and the US between 2008 and 2016.

Dr Nassir Marrouche at the University of Utah said: "The results of this trial underscore the importance of catheter ablation as a mode of treatment, indicating that the procedure should be performed as early as possible and as a first-line therapy in this group of patients."
