The goal of this review is to introduce briefly two modern technologies of remote catheter navigation that are being increasingly used in clinical practice as a support of catheter ablation of different types of cardiac arrhythmias.

Magnetic navigation system Niobe consists of two large magnets that generate permanent and uniform magnetic field. The vectors of the field can be changed in various directions. This allows remote manipulation of specialized magnet-equipped catheter inside the patient´s heart. Robotic system Sensei is based on electromechanical navigation principle. Conventional ablation catheter is introduced into the assembly of two steerable metallic sheaths that control the movements of the tip of ablation catheter remotely. Both systems allow the concomitant use of 3D mapping systems for visualization of mapped chamber (CARTO or NavX).

At present, initial clinical experience with both systems has been published. It is more substantial for the Niobe system, since it is available for longer time. Larger studies are expected that will compare the advantage of remote catheter control with conventional catheter ablation, mainly in complex arrhythmia substrates such as atrial fibrillation or ventricular tachycardias. Their widespread use may significantly minimize radiation burden for patients, and especially for physicians.
