Catheter ablation
Under catheter (composed of the med. Technical terms catheter and ablation ) are cardiac catheterization summarized -based methods by which after an Electrophysiological investigation cardiac arrhythmias can be eliminated. The aim here is to switch off tissue that sends false electrical impulses or to specifically cause scars in the heart that interrupt the transmission of the false impulses.
Catheter ablation, also called renal denervation in this context, is also used for treatment-resistant arterial hypertension . Here, parts of the sympathetic nervous system that run directly on the renal artery are selectively switched off by heat.
The most important method is high-frequency ablation , in which the tissue in the heart is heated with the help of electricity and thus destroyed; an alternative, less common method is cryoablation .
