Catheter ablation of ventricular arrhythmia originating in the tricuspid annulus in a patient with biventricular noncompaction: a case report

It is rare for ventricular tachycardia arising from the right ventricle to originate in the tricuspid annulus, and the clinical presentation and cardiac abnormalities associated with this type of arrhythmia have not been clearly established. This report describes a case of biventricular noncompaction presenting with ventricular arrhythmia originating in the tricuspid annulus and successfully treated with radiofrequency ablation.
