Characterization of Left Atrial Substrate in Patients With Ventricular Arrhythmias — CLASS-VA  

Atrial Remodeling Clinical Trial

Official title: Characterization of Left Atrial Substrate in Patients With Ventricular Arrhythmias

Status Recruiting

Clinical Trial Summary

The goal of this observational study is to analyze the characteristics of left atrial electroanatomical maps in patients without a history of atrial fibrillation but with a high clinical risk of developing it, as indicated by the presence of structural heart disease or a CHA2DS2-VASc score ≥ 2 points. The study cohort will be compared to a historical cohort of patients with diagnosed atrial fibrillation in a propensity-matched fashion.

The main questions it aims to answer are:

• Are the left atrial electroanatomical changes a consequence or a precursor to the development of atrial fibrillation?

• Are the left atrial electroanatomical findings different between patients with atrial fibrillation and those at high risk of developing it?

• What is the prognostic impact of left atrial pathologic changes in patients without diagnosed atrial fibrillation in terms of cardiovascular outcomes?
