Spanish catheter ablation registry. 23rd official report of the Heart Rhythm Association of the Spanish Society of Cardiology (2023).

Introduction And Objectives: We report the results of the 2023 Spanish catheter ablation registry.

Methods: Procedural data were collected and incorporated into the REDCap platform by all participating centers through a specific form.

Results: There were 104 participating centers in 2023 compared with 103 in 2022.

Impact of face masks during the treadmill exercise tests.

Introduction And Objective: There is little literature on the use of face masks in a treadmill test (TMT) during the COVID-19 pandemic. The objective of this study is to analyze the impact of face masks during a TMT performed during the prepandemic (without face mask) and postpandemic (with face mask) era.

Methods: Retrospective observational unicentric study of patients undergoing TMT.

Impact of monitoring on detection of arrhythmia recurrences in the ESC-EHRA EORP atrial fibrillation ablation long-term registry.

Aims: Monitoring of patients after ablation had wide variations in the ESC-EHRA atrial fibrillation ablation long-term (AFA-LT) registry. We aimed to compare four different monitoring strategies after catheter AF ablation.

Methods And Results: The ESC-EHRA AFA-LT registry included 3593 patients who underwent ablation.

Risk stratification of cardiovascular and heart failure hospitalizations using integrated device diagnostics in patients with a cardiac resynchronization therapy defibrillator.

Aims: Cardiac resynchronization therapy defibrillators (CRT-D) are able to monitor various parameters that may be combined by an automatic algorithm to provide a heart failure risk status (HFRS). We sought to validate the HFRS for stratifying patient risk, evaluate its association with heart failure (HF) symptoms, and investigate its utility for triage of automatic alerts.

Methods And Results: Data from 722 patients included in the MORE-CARE trial were analysed in a post hoc analysis.
