Researchers from the Clinico Universitario San Carlos Hospital (HCSC) and Carlos III National Cardiovascular Research Center, with support from the Intergovernmental Foundation for Cardiovascular Research (FIC), were able to confirm safety and efficiency parameters in the procedures. a worn-out from arrhythmias made from the roots of their big heart vessels.

The work, published in Circulation: Arrhythmia and Electrophysiology, published by the American Cardiology Society, will give greater control over a type of complex enterprise and limited activity. learned to date.

“It is not easy to assess the extent of any damage caused by these requests by patients, as samples cannot be used for microscopic and historical analysis therefore, we were able to use a pig animal pig, which was a it is similar to an in vivo method that is clinical for patients, "said Dr David Filgueiras, one of the scientists.

Although most methods of inflation are repelled within the heart holes by the catheter in a direct link to the myocardium target of the tasting, in certain situations the acid must have played from the artist
The roots of the aorta artery or the lung artery with the aim of reducing the myocardium next to these vessels. “This happens when there are symbolic riots or endangering patients, which are up to 5 per cent of procedures for ablation of heart arrhythmia,” said the cardiologist.

Using a hybrid microscope of the arterial wall, the researchers were able to assess the blood damage caused by the radiofrequency application. The research team were able to identify which of the radiofrequency apps had a force of 40W, a temperature of 38 degrees and impedance doses of 16 Ohms which are safe to prevent dangerous damage without interference.

On the other hand, by comparing 40W and with a range of communication devices, by using an Injury Index (LSI) parameter to monitor the crash, the problem was that the lot was wounded. myocardium which was close to the artery followed a string connection with the value of the LSI achieved.

"The data on this work allows us to establish safe and effective feeding limits for radioactive performance in areas that are well aware of major problems, such as the aorta roots and the lungs artery". the Arrhythmia Unit in the HCSC will terminate and a director of the Cardiovascular Center will be the same hospital, Julián Pérez-Villacastín.
