Portuguese National Registry on Cardiac Electrophysiology, 2017 and 2018

Abstract

Abstract Introduction The authors present the results of the national cardiac electrophysiology registry of the Portuguese Association of Arrhythmology, Pacing and Electrophysiology (APAPE) and the Portuguese Institute of Cardiac Rhythm (IPRC) for 2017 and 2018. Methods The registry is annual, voluntary, and observational. Data are collected retrospectively. Developments over the years and their implications are analyzed and discussed. Results In the 22 electrophysiology centers, 3407 ablations were performed in 2017 and 3653 ablations in 2018. Atrial fibrillation (AF) ablation was the most frequently performed procedure: 1017 ablations in 2017 and 1222 procedures in 2018. Of the patients undergoing AF ablation, 63% were male, 60% were between 50 and 69 years old and 74% had paroxysmal AF. Clinically relevant complications were reported in 0.8% of the procedures. In 2017, 216 ventricular tachycardia or ventricular fibrillation (VT/VF) ablation procedures were performed in 15 centers. In 2018, 19 centers performed 249 TV/VF ablations. About 45% of VT/VF ablations were performed in patients with structural heart disease. Complications were reported in 3.2% of the procedures, including one death (0.2%). Conclusions The national electrophysiology registry showed a sustained increase in the number of catheter ablations. In addition, procedural complexity increased and AF ablation assumed a dominant position among the procedures performed.
