Diagnosis-to-ablation time predicts recurrent atrial fibrillation and rehospitalization following catheter ablation.

ABSTRACT:

Background

Wait times for catheter ablation in patients with symptomatic atrial fibrillation (AF) may influence clinical outcomes.

Objective

This study examined the relationship between the duration from AF diagnosis to ablation, or diagnosis-to-ablation time (DAT), on the clinical response to catheter ablation in a large nationwide cohort of patients.

Methods

We identified patients with new AF who underwent catheter ablation between January 2014 and December 2017 using the IBM MarketScan databases. Cox proportional hazard models were used to estimate the strength of the association between DAT and the outcomes of AF recurrence and hospitalization at 1 year postablation.

Results

Among 11,143 AF patients who underwent ablation, the median age was 59 years, 31% w
