With the CARTO system, the heart chambers can be reconstructed and the image obtained can be used as a “GPS map”, locating the place of origin of these arrhythmias with great accuracy, which facilitates their elimination.By not requiring X-rays (fluoroscopy), the patient will not be exposed to radiation with the use of CARTO (if the “zero-fluoroscopy” method is used), or in any case, will be minimal.CARTO is a special 3D electro-anatomical reconstruction system that allows navigation inside the cardiac chambers in real-time, without fluoroscopy, and with great precision.Although many of these arrhythmias can be treated with the conventional system, there is a group of complex arrhythmias that require special mapping called CARTO, which consists of three-dimensional (3D) electro-anatomical mapping. This procedure allows very small scars to be created in the areas of the heart that are involved in heart rhythm problems. Catheter ablation and CARTO systemĨ0% of cardiac arrhythmias can be treated by catheter ablation, thus eliminating the need for medication. Arrhythmias manifest differently in each individual, either with palpitations, racing heart (“tachycardia”), dizziness, shortness of breath, or even loss of consciousness (fainting). This causes you to suffer from tachycardia (heartbeats too fast), bradycardia (heartbeats too slow), or irregular heartbeats.Īny individual can present arrhythmias regardless of their age, that is, from children to older adults. Our data clearly demonstrate that Rhythmia was proved to be effective and well applicable but more data will be mandatory before final conclusions can be drawn.Ĭarto system Rhythmia system atrial fibrillation catheter ablation electroanatomic mapping.Arrhythmias occur when the electrical impulses that coordinate the heartbeat are abnormally fast, irregular, or come from places other than the normal conduction system of the heart. The present study reports our first clinical experience using Rhythmia in direct comparison with the established Carto system for AF ablation. From Kaplan-Meier analysis, the event rate estimations were 15% versus 13.5%, respectively. During follow-up, 84.8% of patients remained free from any AF/AT-recurrence using Carto versus 88.2% when using Rhythmia (P = 0.53). There was no difference regarding total ablation time (P = 0.707), total procedure duration (P = 0.99), and acute procedural success. Comparing Rhythmia- versus Carto-guided ablation approaches, we observed a significantly longer total mapping time (P = 0.001), longer total fluoroscopy time (P = 0.001), more delivered RF-applications (P = 0.019), and longer total RF-duration (P = 0.002). The Carto-guided procedures were performed using point-by-point acquisition according to our routine approach, whereas for Rhythmia, fast anatomical mapping was utilized. The aim of this study was to directly compare point-by-point versus rapid ultra-high-resolution EAM in patients scheduled for ablation of atrial fibrillation (AF) with focus on procedural data, acute success, and midterm clinical outcome.Ī total number of 74 consecutive patients (48/74 male) with symptomatic AF were scheduled to undergo pulmonary vein isolation (PVI) using either Carto or Rhythmia. In this context, the novel Rhythmia system sets a new bar in fast high-resolution mapping. Three-dimensional electroanatomical mapping (EAM) is an established tool facilitating catheter ablation.
