The First Three Years of Ablation Therapy in Cardiac Arrhythmias: Single Centre Experience

Abstract

Improvements in both evaluation of intracardiac signals and molecular data yielded an easy understanding of complex cardiac arrhythmias and channelopathies in last years. However, the mentioned techniques are not applicable by all health providers because of high costs, requirement of well-educated team members, and the most importantly the presence of long learning curve for cardiologists In this article, the catheter ablation of arrhythmias in the Van Yuzuncu Yil University Department of Cardiology in last three years will be reviewed. Intracardiac signals were filtered at 20-500 Hz, amplification gains were 10-80 mm/mV. All signals displayed and acquired on an electrophysiological recording system (EP-TRACER 2 system, Schwarzer Cardiotek, Germany). All types of arrhythmias such as atrioventricular nodal reentry tachycardia, atrioventricular reentry tachycardia, atrial flutter, atrial tachycardias, atrial fibrillation, premature ventricular contractions, and ventricular tachycardias were ablated according to the latest quidelines and techniques. A total of 430 patients were screened in this trial. The success rate in the ablation of atrioventricular nodal reentry tachycardia, atrioventricular reentry tachycardia, atrail flutter, atrial tachycardias, atrial fibrillation, premature ventricular contractions, and ventricular tachycardias was 100%, 88.2%, 88.8%, 72.2%, 100%, 73.9%, and 87.5% respectively. There was only one death among 430 ablation procedures in our centre and the reason of death was not clear because of patient’s other co-morbidities. Otherwise, our success and complication rates were similar with the results of most advanced centres in all around of the world. © 2020, Yuzuncu Yil Universitesi Tip Fakultesi. All rights reserved.
