Summary

The aim of this study is to investigate whether renal denervation can reduce arrhythmia burden in patients with recurrent, paroxysmal atrial fibrillation despite durable pulmonary vein isolation.

Detailed description

Pulmonary vein isolation is the treatment of choice in symptomatic patients with paroxysmal atrial fibrillation. Despite durable pulmonary vein isolation, 15% of patients continue to have episodes of atrial fibrillation because of triggers of atrial fibrillation localized outside the pulmonary veins. Additional ablation of these triggers is difficult because they often cannot be localized. The autonomous nervous system does influence these triggers and modulation of the autonomous nervous system with the goal to reduce sympathetic activity may be an alternative approach to suppress these extra-pulmonary vein triggers. Renal denervation does reduce sympathetic activity and is successfully used to treat drug-resistant arterial hypertension. The combination of pulmonary vein isolation with renal denervation has already been shown to be superior to pulmonary vein isolation alone in patients with paroxysmal atrial fibrillation regarding arrhythmia-free outcome. The investigators hypothesize that renal denervation can suppress atrial fibrillation in patients with recurrent episodes of paroxysmal atrial fibrillation despite durable isolation of the pulmonary veins. The best way to assess atrial fibrillation burden is with an implantable cardiac monitor (ICM), which the investigators will use both before and after renal denervation, to gather detailed data on daily atrial fibrillation burden.
