Predictors and Prognostic Significance of Tachycardiomyopathy: Insights from a Cohort of 1269 Patients Undergoing Atrial Flutter Ablation

Abstract

Marked LVEF improvement was observed in 56% of patients with baseline LVEF <40% at 6 months after ablation. These patients had similar survival to patients without baseline systolic dysfunction, whereas patients who remained with LVEF <40% had a threefold increase in mortality rates.
