ARVD Clinical Features.
Arrhythmogenic right ventricular dysplasia (ARVD) is a
poorly understood and often underdiagnosed cardiomyopathy.
The disease is
characterized by arrhythmic manifestations, possibly due to replacement of
myocardium of the right ventricle by fibroadipose tissue. ARVD should be
considered as a cause of ventricular tachycardia of left bundle branch block
configuration and/or sudden death, particularly during exercise in young
subjects. The electrocardiogram (ECG) may show anterior precordial T wave
inversion, particularly in lead V2 and/or a QRS complex duration > or = 110
ms in the right precordial leads.
Echocardiographic studies focusing on the size and wall-motion abnormalities
of the right ventricle are useful in confirming the diagnosis.
Cinemagnetic resonance imaging demonstrates abnormal fatty infiltration of
the right ventricular myocardium and can show increased right ventricular
dimensions as well as wall-motion abnormalities. Contrast ventricular
angiography remains the gold standard to establish the diagnosis but must be
performed with appropriate views and with care to avoid ventricular
premature beats (Marcus & Fontaine, 1995).
