Intracardiac echocardiography use and outcomes after catheter ablation of ventricular tachycardia
Key result
ICE use during outpatient VT ablation linked to ~24% fewer all-cause and cardiovascular readmissions.
- 24% lower risk
- n=2,820
Why the study?
The study was designed to compare outcomes in patients with ICD/CRT-D undergoing outpatient VT catheter ablation using intracardiac echocardiography versus no intracardiac echocardiography.
Does intracardiac echocardiography (ICE) reduce readmissions in patients with ICD/CRT-D undergoing outpatient VT catheter ablation?
Population
Patients with ICD/CRT-D undergoing outpatient VT catheter ablation (n = 1143 ICE vs n = 1677 non-ICE)
Comparison
ICE use vs no ICE
Design
Propensity-matched observational cohort study

Intervention
Intracardiac echocardiography (ICE) use during VT catheter ablation

Main Result
Effect estimate: 24% lower risk
The use of intracardiac echocardiography during outpatient VT ablation in patients with ICD/CRT-D is associated with significantly lower risks of all-cause, cardiovascular, and VT-related readmissions.

Field et al. (2020) conducted an observational in Ventricular tachycardia (n=2,820). Intracardiac echocardiography (ICE) vs. No ICE was evaluated on All-cause, cardiovascular-related, and VT-related readmissions (24% lower risk). Intracardiac echocardiography use during outpatient ventricular tachycardia catheter ablation was associated with a 24% lower risk of all-cause and cardiovascular-related readmissions.
