Ventricular Tachycardia in a Patient with Biventricular Noncompaction.

Patients with ventricular noncompaction are susceptible to developing ventricular tachycardia. Commonly, the origin of ventricular tachycardia is endocardial; however, epicardial origins and scar cannot be excluded and should be considered when poor endocardial mapping is present. Other cardiomyopathies, such as arrhythmogenic right ventricular cardiomyopathy, can coexist with ventricular noncompaction and should be excluded in these patients.
