How successful is radio frequency ablation

Atrial fibrillation is the most common rhythm disorder in adulthood. Many people with atrial fibrillation come to the doctor with heart problems that manifest themselves in the form of a racing heart, irregular pulse, shortness of breath, chest pain, loss of performance or dizziness. A dreaded complication of the disease is stroke, so that most people have to be treated with drugs to stabilize the pulse and with blood thinners after a thorough medical evaluation.

Effective therapy in younger people

Especially in younger people with early forms of atrial fibrillation, which only occurs now and then and not yet continuously, catheter ablation is an effective therapy with which the problem can be permanently eliminated.

The Ordensklinikum Linz Elisabethinen has held a leading position in Austria in the field of interventional treatment of cardiac arrhythmias for many years. In addition to its technical expertise, the department is also recognized in Europe for its high level of scientific competence. That is why this center was chosen to be one of the first in Europe to test a groundbreaking development on humans for the first time. If the positive results are also confirmed in the other patients across Europe, the commercial launch can be expected in early 2019.

Catheter ablation corrects cardiac arrhythmias

During the ablation, the cardiologist obliterates those areas in the heart tissue that trigger the false currents. The area to be treated is localized with the help of a catheter, which is advanced from the groin to the heart. Electrodes at the tip of the catheter measure the heart currents and give the doctor detailed information on where the ablation catheter must then be precisely placed.

Gentler and safer

With the new catheter it is possible to obliterate the heart wall with a very high frequency. The microsensors measure the temperature and switch off the power when the critical temperature of 65 degrees is exceeded. This means that the dreaded perforation of the heart wall due to excessively high temperatures can now be prevented. With this "safeguard", the ablation can take place much faster in the future because the doctor no longer has to carefully and slowly approach the heart tissue.

While the procedure used to take up to three hours, an ablation can now be performed in an hour. This makes the procedure gentler and safer for the patient. In addition, the method is easier for doctors to learn.
