Research projects on atrial fibrillation


Revolutionary method based on electroporation for the treatment of atrial fibrillation (AF).

The multi-centre randomized BEAT AF study brings together nine European clinical centres to demonstrate that pulsed electric field catheter ablation (electroporation) is more effective, safer and faster than radiofrequency, the reference treatment to date for patients with AF. It will make it possible to reduce the recurrences that remain frequent and will be without damage to the collateral structures. Learn more.

This project has received funding from the European Union’s Horizon 2020 research and innovation programme under grant agreement no. 945125.

Mechano-electrical coupling in the infundibulum of the healthy right ventricle and in pressure overload.

The right ventricular infundibulum is one of the main anatomical origins of ventricular arrhythmias and sudden death. Myocardial stretch could be an important regulator, causing arrhythmias in the right ventricle. The MEGaVOLT project investigates the contribution of this acute and chronic stretch in right ventricular outflow obstruction to identify the mechanisms associated with chronic infundibulum stretch.
