Catheter ablation of atrial fibrillation in patients with cardiac amyloidosis and sarcoidosis: procedural findings and outcomes.

ABSTRACT:

Aims

The diagnosis of infiltrative cardiomyopathies has increased over last years. Catheter ablation is becoming the preferred approach for managing atrial fibrillation (AF) in these patients. This study aims to characterize differences in procedural findings during AF ablation in patients with and without infiltrative cardiomyopathies.

Methods and results

Patients with cardiac amyloidosis and cardiac sarcoidosis undergoing first-time AF ablation were propensity score matched in 1:4 ratio to separate reference groups that received trigger provocative manoeuvres (isoproterenol infusion and/or atrial burst pacing) and had no prior cardiac surgery. Non-pulmonary vein (PV) triggers [defined as ectopic foci initiating AF or sustained focal atrial tachycardia (AT)] and macro-reent
