Impact of catheter ablation for ventricular tachycardia on left ventricular ejection fraction in patients with structural heart disease.

ABSTRACT:

Background

Catheter ablation (CA) is efficacious for the treatment of ventricular tachycardia (VT) in patients with structural heart disease; however, heart failure contributes to long-term mortality in this cohort. Whether CA worsens left ventricular function requires investigation.

Methods

We retrospectively analyzed 142 consecutive patients with structural heart disease undergoing CA for VT. Pre-ablation left ventricular ejection fraction (LVEF) was compared to LVEF postablation, predictors of change in LVEF were identified, and the relationship between change in LVEF and arrhythmic recurrence was assessed.

Results

Patients with ischemic cardiomyopathy (ICM) had lower pre-ablation LVEF than patients with non-ischemic cardiomyopathy (NICM) (36.2 ± 14.3% vs. 50.8 ± 1
