[Diagnostic elements of a right papyraceous ventricle. The value of nuclear magnetic resonance]

We are reporting the case of a young man presenting repeated syncopes linked to episodes of ventricular tachycardia. The rhythm disorders were due to the existence of a papyraceous right ventricle with concomitant involvement of the left ventricle disclosed during the etiological work-up. We are reporting, at this time, the usual diagnostic elements of this disease, but mostly original data provided by the nuclear magnetic resonance, as the clinical examination and the EKG are often less revealing except for late potentials always found in the arrhythmic form. The right, ventricular dysplasia and the papyraceous right ventricle represent two very close entities. Particular characteristics enable to differentiate them and also the differential diagnosis with other diseases are discussed by stressing the advantage of magnetic resonance imaging, a new method, non invasive, which lends itself well to the analysis of cardiac morphology.
