Invasive percutaneous treatment of cardiac arrhythmias involves multiple electronical control systems to allow the operator to know the exact position of the catheters at all times during the procedure. Through these catheters, we study the electrical activity generated inside the heart, we create electro-anatomical maps of the cardiac chambers and search for the origin of arrhythmias. Often, the creation of a focal lesion is able to terminate the arrhythmia; in other cases, the only effective treatment will be to implant a pacemaker or an internal defibrillator.
Our unit is equipped with very advanced electro-anatomical mapping and navigation systems (Ensite Precision, Carto 3 and Rhythmia) and with laboratories with highly specialized X-Ray technology for its use during procedures. We also have rotational angiography systems available allowing the spatial reconstruction of the heart in few seconds. Most interventions to treat the foci generating arrhythmias are performed through radiofrequency generators, capable of burning those small arrhythmogenic foci. Similarly, we have cryoablation devices, that allow us to treat complex arrhythmias through local freezing of the tissue.
