Zero-Fluroscopy ablation for cardiac arrhythmias: A single-center experience in Mexico

Objective: Catheter ablation (CA) is a highly effective procedure for treating symptomatic tachyarrhythmias. However, the use of fluoroscopy, which is commonly employed in CA, exposes patients and medical personnel to ionizing radiation and its associated health risks. To address this concern, alternative techniques such as electro anatomical mapping and intracardiac ultrasound have emerged as viable options for performing CA without fluoroscopy. This study aims to describe the process and outcomes of mapping and ablation procedures performed without fluoroscopy in a Mexican electrophysiology laboratory. Methods: Fifty-two patients with arrhythmias except atrial fibrillation were included in the study. The three-dimensional mapping system ENSITE Precision (Abbott) and intracardiac ultrasound, were used when the operator deemed it necessary. We assessed complications and immediate success of catheter ablation in our patients. Results: A total of 52 patients were included in the study from January 2021 to July 2022of which 24 were men (42%) and 32 were women (57%). Only four patients received diagnostic three-dimensional mapping as a result of clinical tachycardia not being caused. An ablation of 52 arrhythmias substrates was performed with the following results:
