Robot-assisted ablation procedures are designed to provide more precise and safer treatment for arrhythmias.
Robot-assisted ablation takes the precision and safety of electrophysiological procedures to a new level. Magnetic navigation reduces radiation exposure, improves the success rate of complex arrhythmia management, and ensures reliable catheter navigation even in challenging anatomical situations. In Hungary, this technology is available exclusively within the clinical setting of the University of Szeged, and in the private healthcare sector, it is available only at Mediversal.
Robot-assisted ablation – using the Stereotaxis magnetic navigation system – offers advantages that cannot be achieved, or only to a limited extent, by manual techniques. The most important feature is precise, stable and continuous catheter navigation, which enables safe treatment even in complex anatomical conditions. These highly flexible catheters, guided by a magnetic field, reduce the risk of perforation and cardiac tamponade whilst maintaining constant contact with the heart muscle.
This technology significantly reduces patient and operator exposure to radiation, which is a major health benefit in the long term. Clinical trials have shown that robot-assisted ablation improves both acute and long-term success rates, particularly in cases involving complex arrhythmias, congenital heart defects, or previous surgical procedures. The robotic navigation system features advanced image integration capabilities that provide real-time feedback, supporting precise lesion formation and safe energy delivery. Taken together, these features make this technology a modern, reliable and effective solution that brings the quality of electrophysiological procedures to a new level.
In certain arrhythmia cases – where a single catheter is sufficient – the procedure can be performed via a venous puncture in the arm. This approach allows for a more comfortable and quicker recovery, and for many patients this means they can be sent home on the day of the procedure. In this case also, the precision of the robot-assisted system ensures stable catheter navigation and safe ablation.
If you experience any of the following symptoms, it is important to have a healthcare professional investigate the underlying cause as soon as possible:
The timely detection and treatment of arrhythmias are crucial in preventing complications. If you are in doubt, it is best to seek professional help – a prompt diagnosis could save your life.
A detailed assessment (laboratory tests, ECG, ultrasound, and CT/MRI if necessary) is carried out prior to the procedure. This is followed by sterile preparation, intravenous cannulation and the insertion of catheters.
Catheters are introduced into the appropriate chambers of the heart. The robot-assisted system enables precise, stable and well-controlled navigation, allowing safe access also to complex anatomical areas that are difficult to reach, with minimal mechanical stress.
The operating physician guides the catheter from the control room. The system provides a 3D electroanatomic map of the heart’s electrical activity, accurately identifying the point of origin of the arrhythmia. Advanced features of Stereotaxis (e.g. ablation history, e‑contact) provide real-time feedback on the position of the catheter and tissue contact.
Once the source of the arrhythmia has been identified, ablation starts. The robot-assisted catheter ensures stable contact, resulting in uniform and controlled energy delivery. This reduces the risk of perforation and tamponade, and improves both acute and long-term success rates.
Following ablation, repeat mapping is performed to assess whether the arrhythmia has resolved, or whether a gap persists between the ablation lines. The catheters are then removed, the puncture sites are dressed, and the patient is kept under observation for a short while. Most patients are allowed to go home the same day or the next day.
The aim of preparing for robot-assisted ablation is to ensure that the procedure is carried out as safely and effectively as possible. Before the examination, your doctor will review your previous medical records, medications and any underlying conditions in detail. It is important to inform your healthcare professional about all the medicines you are taking, particularly anticoagulants and medicines that affect your heart rhythm, as it may be necessary to adjust the dosage or temporarily stop taking them.
It is generally recommended that you fast for a few hours before the procedure, and you should wear comfortable clothing. Please bring any previous ECG, ultrasound or CT/MRI findings with you to the hospital, along with a list of any medication you take regularly. On the day of the procedure, a venous cannula is inserted and the necessary preparations are made.

The procedure is usually painless, as you will be given a local anaesthetic and will not feel the movement of the catheters. You may feel a slight pressure at the puncture site, but most patients experience no discomfort during the procedure. Robot-assisted technology ensures more precise and stable catheter navigation, thereby minimising discomfort.
The duration of the procedure depends on the type of arrhythmia; it usually lasts 1.5 to 3 hours. Advanced navigation of the robot system often speeds up the process, as it allows the target area to be accessed more accurately and efficiently.
Most patients are allowed to go home the next day. The observation period is usually short, and recovery may also be quick, as robot-assisted technology reduces the risk of complications.
In case of ARM access, when the procedure is performed through the arm, a significant proportion of patients are sent home after a few hours of observation, since the puncture site is stabilised more quickly and mobilisation is also easier.
Yes. Numerous studies confirm that robot-assisted ablation is associated with lower radiation exposure; it ensures more stable catheter contact and reduces the risk of perforation or cardiac tamponade. The robotic navigation system is particularly advantageous in complex anatomical cases.
The technology is suitable for the treatment of atrial fibrillation, atrial flutter, supraventricular tachycardias, ventricular tachycardias and idiopathic arrhythmias. It is particularly useful in cases of congenital heart defects or previous heart surgery.
Robot-assisted ablation – using the Stereotaxis magnetic navigation system – is currently available in Hungary only at Mediversal, a private healthcare provider backed by the clinical expertise of the University of Szeged. This offers patients a unique opportunity to receive treatment for arrhythmia supported by internationally recognised robot-assisted navigation technology.
