Navigation system for the treatment of arrhythmia

2022: Getting Started

The National Medical Research Center (NMIC) named after E.N. Meshalkin in Novosibirsk developed an electrophysiological navigation system that allows you to quickly build a 3D model of the heart chamber to localize the focus of pathology that causes arrhythmia. The press service of the organization reported this in mid-March 2022.

Technology to help improve the effectiveness and safety of arrhythmia treatment allows for accurate installation of a catheter to diagnose the heart in various forms of impaired regularity and sequence of heart contractions. During the intervention, the surgeon focuses on the parameters that the navigation system provides.

In Novosibirsk, developed a 3D system for combating arrhythmia

According to the developers, a significant advantage of the new navigation system is the use of local bioimpedance - a diagnostic method based on measuring the electrical resistance of tissue to alternating current. All biological tissues: blood, vessel walls, muscle cells of the heart (cardiomyocytes) and so on - have different resistance. The use of this method during surgery allows a person skilled in the art to better orient themselves when moving the catheter in the heart cavities and perform a more effective and safe effect.

The system of Novosibirsk scientists, unlike previously used ones, makes it possible to assess tissue damage at the time of application of radio frequency exposure, which provides additional safety of the procedure.

As stated at the National Medical Research Center (NMIC) named after E.N. Meshalkin, the system takes no more than 10-15 minutes, while using a conventional catheter with four electrodes takes almost an hour.

By mid-March 2022, specialists at the Meshalkin Center performed more than 50 successful surgical interventions for complex forms of heart rhythm disorders using a new generation of electrophysiological navigation system.^[1]
