Introduction: Strategies beyond pulmonary vein isolation (PVI) in persistent atrial fibrillation (persAF) are debated. A novel mapping tool provides algorithmic detection of ablation targets based on electrogram (EGM) properties specific to stable localized rotational activations.
Methods: The mapping tool was used on 31 patients (20 de novo).
Article Synopsis
- The study investigates the role of galectin-3, a biomarker linked to fibrosis, in predicting outcomes for heart failure patients with reduced left ventricular function undergoing ablation for persistent atrial fibrillation (AF).
- It analyzes serum galectin-3 levels in 75 patients and finds that lower levels are associated with better survival rates and response to treatment.
- The results suggest that measuring galectin-3 can help clinicians tailor therapeutic strategies for patients with both heart failure and persistent AF.
Background: Approximately one-third of patients do not respond favourably to cardiac resynchronization therapy (CRT). A longer distance between ventricular leads may improve response.
Aim: To study the impact of the true three-dimensional interlead distance (ILD) on outcomes.
Galectin-3 is a biomarker of fibrosis and atrial remodeling, involved in the mechanisms of initiation and maintenance of atrial fibrillation (AF). We sought to study the accuracy of galectin-3 level in predicting recurrences of AF after ablation. Serum concentrations of galectin-3 were determined in a consecutive series of patients addressed for AF ablation in our center.

However, long-term outcomes after AVNA are uncertain, especially in light of irreversible pacemaker dependence.
Methods And Results: We examined 9122 consecutive patients with AF.
