Our projects focus on experimental, translational and clinical research on diagnosis and therapy of cardiac arrhythmias.

About our research group/lab

Our research

General aims:

Our ambition is to decrease the burden of cardiac arrhythmias by providing patient-tailored therapy targeting electropathology.
Our main goals are:
  1. Design and test novel bio-electrical diagnostic tools.
  2. Unravel arrhythmia-related electropathology.
  3. Design and test novel therapies targeting electropathology.

Our strategy to achieve these goals is to unravel and measure electropathology by:

Pillar I: designing advanced (non-), (minimally)- invasive signal-recording techniques  
Pillar II: designing advanced signal-processing techniques.
Pillar III: performing mapping studies in cell or tissue cultures, animal models and patients with various diseases.
Pillar IV: dissection of molecular pathways of structural remodelling underlying cardiac arrhythmias.

Innovative scientific contributions include:

  • Discovery of novel mechanisms underlying persistence of AF.
  • Introduction endovascular mapping approach guiding ablative therapy of atrialtachyarrhythmias in patients with congenital heart disease.
  • Development of a novel, intra- operative epicardial mapping approach.

Quest of the arrhythmogenic substrate of atrial fibrillation

We developed a novel, intra-operative mapping approach to quantify electrical properties of the entire epicardial surface of the right and left atrium including Bachmann’s bundle at a high resolution scale (2mm, >1900 sites). The purpose of this approach is to accurately identify and localize electropathology associated with AF in patients with varying underlying heart diseases. By applying this technique, we can investigate features, severity and extensiveness of electropathology in the individual patient during any rhythm. This technology is the golden standard for development of less (endovascular) or even non-invasive measurements.

Atrial Fibrillation FIngerPrinting: Spotting Bio-Electrical Markers to Early Recognize Atrial Fibrillation by the Use of a Bottom-Up Approach (AFFIP)

Early treatment of atrial fibrillation (AF) is hampered by lack of accurate diagnostic instruments to recognize patients who will develop AF. Our goal is to develop age and gender based, bio-electrical diagnostic tests, consisting of electrical signal profiles and levels of atrial specific tissue/blood biomarkers. This novel diagnostic instrument can be used for early recognition of AF by determination of stage of the electropathology. As such, AF Fingerprinting enables optimal AF treatment, thereby improving patient’s outcome.

DANARA: Dysrhythmias in pAtients with CongeNital HeARt DiseAse

The incidence of dysrhythmias in patients with congenital heart defects after palliative or corrective cardiac surgery is higher compared to subjects with normal atrial anatomy without prior cardiac surgery. The aim of our (international, multi-center) studies is to examine characteristics of cardiac dysrhythmias over time in patients with congenital heart defects by studying clinical presentation, electrocardiographic and electrophysiological characteristics of atrial and ventricular tachyarrhythmia over time in a cohort of patients with congenital heart defects.  In addition, innovative mapping studies in this patient group are performed to investigate the pathophysiology of dysrhythmias.
