Welcome to the website of Atrial Fibrillation Innovation Platform (AFIP), founded by Prof. Dr. B. Brundel and Dr. N. de Groot. We organize a variety of (inter)national research projects on atrial fibrillation (AF). Our research projects are aimed at unraveling the pathophysiology of AF, development of innovative diagnostic tools to determine the stage of AF and discovery of novel AF (drug) therapies.

Prof. Dr. Bianca Brundel
Brundel is a molecular and cellular biologist at VU Medical Center in Amsterdam, the Netherlands
Role of protein homeostasis and the protein quality control system underlying atrial fibrillation.
Bianca Brundel received her PhD from the University Medical Center Groningen, The Netherlands and was trained in molecular and cellular biology (VU, Amsterdam) and clinical pharmacology (UMCG). Bianca is professor at the physiology department at the VU University Medical Center Amsterdam. Her research is focused on the molecular mechanisms driving proteostasis derailment and pathophysiology of cardiac diseases, including atrial fibrillation and cardiomyopathies. Molecular findings are used to identify novel druggable targets. Her laboratory utilizes experimental cardiomyocyte and Drosophila cardiac disease models in combination with genetic and pharmacological manipulations. She is established investigator, funded by the Dutch Heart Foundation and project leader of translational research projects, including HALT&REVERSE (LSH-health and DHF) and AFFIP (CVON) and DOSIS (CVON, together with Prof. Dr. Jolanda van der Velden). Furthermore, together with Dr. Natasja de Groot, she founded the Atrial Fibrillation Innovation Platform to promote translational studies in collaboration with patients. As such, she contributed to forwarding candidate drugs into (pre-)clinical proof-of-principle studies.

Fibrillation Academic Center and Medical Delta Cardiac Arrhythmia Lab.
She has been involved in writing various international guidelines of the
European Society of Cardiology, European Heart Rhythm Association and
Heart Rhythm Society and she is an active EHRA Board/committee
member since 2009. She is also president of the committee project group
Dutch AF Guidelines 2018. She is reviewer and abstract grader of a variety
of international journals and congresses.
Her research projects are aimed at unravelling the pathophysiology of
complex cardiac tachyarrhythmias, particularly atrial fibrillation and
tachyarrhythmias in patients with congenital heart disease. For this
purpose, she has developed a unique way of analyzing cardiac signals and
cardiac mapping procedures. Her research program was in 2018 rewarded
with the prestigious VIDI-grant
Together with prof. Dr. B. Brundel, she is director and co-founder of the
Atrial Fibrillation Innovation Platform (AFIP).

For this purpose, we have created a unique cardiac mapping technology, and various experimental model systems to mimic clinical AF.
Examples of our scientific contributions include:
1. Discovery of the key elements of the arrhythmogenic substrate underlying AF;
2. Electrical endo-epicardial asynchrony as a cause for persistence of AF;
3. Introduction of endovascular mapping approaches guiding ablative therapy of atrial achyarrhythmias in patients with congenital heart disease;
4. Analysis of the time course of AF in patients with congenital heart disease;
5. Development of a novel, intra- operative epicardial mapping approaches to identify electropathology;
6. Discovery of heat shock protein-inducing compounds to prevent AF progression;
7. Key role for HDAC6 activation in structural and electrical remodeling;
8. Endoplasmic reticulum stress underlies AF onset and progression;
9. Identification of various marketed drugs, including GGA, 4PBA, which protect the heart against AF;
10. Characterization of changes in Protein Quality Control system and proteostasis which underlie electropathology and AF progression.
