Comparison of Effective and Ineffective Target Sites That Demonstrate Concealed Entrainment in Patients With Coronary Artery Disease Undergoing Radiofrequency Ablation of Ventricular Tachycardia
Why the study?
Do specific mapping criteria improve the positive predictive value of concealed entrainment for successful radiofrequency ablation of ventricular tachycardia in patients with coronary artery disease?
Population
14 consecutive patients with hemodynamically stable monomorphic ventricular tachycardia and coronary artery…

Implication
Isolated mid-diastolic potentials may raise concealed entrainment PPV for VT ablation sites; hypothesis-generating pending prospective validation.
Structured PICO
Do specific mapping criteria improve the positive predictive value of concealed entrainment for successful radiofrequency ablation of ventricular tachycardia in patients with coronary artery disease?
P
Population
14 consecutive patients with hemodynamically stable monomorphic ventricular tachycardia and coronary artery disease
I
Intervention
Radiofrequency ablation at sites demonstrating concealed entrainment
O
Outcome
Successful ablation of the targeted ventricular tachycardia
The presence of associated mapping criteria, particularly isolated mid diastolic potentials, significantly enhances the positive predictive value of concealed entrainment for identifying successful VT ablation sites.
