Radiofrequency ablation of cardiac arrhythmia using the Stereotaxis robotic system. This operation consists of inserting a catheter into the heart, emitting radio waves that will cauterize cardiac tissue responsible for rhythmic irregularity. The Stereotaxis robotic system is a magnetic navigation system. It uses a rotating magnetic field enabling the ablation catheter to be guided from a distance. The system consists of two giant magnets placed on each side of the operating table. The operation is carried out under radioscopic control. It is a more precise technique that reduces the risk of complications, procedure length and the patient£s and radiologist£s exposure time to x-rays. A patient suffering from atrial fibrillation. Puncture of the vein.
