Impact of catheter ablation in patients with atrial flutter and concurrent heart failure.

ABSTRACT:

Background

No studies assessed impact of atrial flutter (AFL) ablation on outcomes in patients with AFL and concurrent heart failure (HF).

Objectives

To assess the effect of AFL ablation on mortality and HF readmissions in patients with AFL and HF.

Methods

This retrospective cohort study identified 15,952 patients with AFL and HF from the 2016-17 Nationwide Readmissions Database. The primary outcome was a composite of all-cause mortality and/or HF readmission at 1 year. Secondary outcomes included HF readmission, all-cause mortality, and atrial fibrillation (AF) readmission at 1 year. Propensity score match (1:2) algorithm was used to adjust for confounders. Cox proportional hazard regression was used to generate hazard ratios.

Results

Of the 15,952 patients, 9
