Key result
Radiofrequency ablation of the noncoronary cusp should be considered for ventricular tachyarrhythmia when attempts at other common left ventricular outflow tract sites are unsuccessful.
Why the study?
Does radiofrequency catheter ablation eliminate ventricular tachyarrhythmia originating from the noncoronary cusp?

Does radiofrequency catheter ablation eliminate ventricular tachyarrhythmia originating from the noncoronary cusp?
The noncoronary cusp is an important alternative site to consider for catheter ablation of left ventricular outflow tract ventricular tachycardia when standard sites fail.
Alasady et al. (2009) studied Noncoronary cusp ventricular tachycardia. Radiofrequency ablation was evaluated. Radiofrequency ablation of the noncoronary cusp should be considered for ventricular tachyarrhythmia when attempts at other common left ventricular outflow tract sites are unsuccessful.
