- W4280493417 abstract "Abstract Funding Acknowledgements Type of funding sources: None. Introduction Premature ventricular complex(PVC) catheter ablation is required in a wide spectrum of the population.Ionizing radiation exposure in this procedure carries health risks, especially in young patients. Purpose In this prospective observational study we describe our experience in PVC ablation without fluoroscopy Methods 26 patients were included, submitted to PVC ablation without fluoroscopy between October 2018 and November 2021, in our center. Baseline characteristics of the population, acute success and complications derived from the procedure were evaluated, as well as recurrence rate during follow-up. Results Mean age was 45.5± 16.3 years old, with a 46.2% of men. Most often cause of ablation were palpitations(73.1%),followed by reduced LVEF(19.2%). Mean LVEF by transtoracic echocardiography was 52.4 ± 11%. 38.5% had a cardiopathy, among them the most common was tachycardiomyopathy(49.9%).Mean PVC burden pre-ablation was 23.6±11.5%. 65% of patients were taking beta blockers. The most frequent PVC origin was the right ventricle outflow tract(RVOT), with a 65.4% prevalence, followed by the left ventricle outflow tract(LVOT) with 15.4%.We used a 3D electroanatomical navigation system in all cases,while intracardiac echocardiography was used in 88.5% and a contact force catheter for mapping(57.7%) and ablation(92.3%).The mean maximum radiofrequency power applied was 34 ±5.8W, with a median time of 240 seconds. Median number of applications was 6 and mean total time of procedure was 210 ±67,5 minutes. 28ms median best prematurity. Suppression of PVC was achieved in 88.5%. There was only two complications(7.6%): pericardial effusion without the need for pericardiocentesis and right brunch block.Median follow-up of 3 months, with 23% of recurrences. Most of patients(57.7%) did not require antiarrhythmics drugs during it. Conclusions Zero fluoroscopy PVC ablation is a safe procedure with no major complications and good rates of success and recurrence in our experience" @default.
