An international study involving the Heart Center of the University Medical Center Göttingen (UMG) shows that pulsed field ablation is more effective, gentler and associated with fewer complications than other methods for treating atrial fibrillation. With the pulsed field method, the areas of the heart tissue responsible for the development of atrial fibrillation are specifically sclerosed by means of electrical impulses and not by heat or cold as with other methods. The results of the MANIFEST-17K study were published in the renowned journal Nature Medicine.
