REPORT OF AN ATYPICAL CASE WITH ARRHYTHMOGENIC RIGHT VENTRICULAR DYSPLASIA OR UHL'S ANOMALY ATIPICIDADES EN UN CASO CON DISPLASIA ARRITMOGÉNICA DEL VENTRÍCULO DERECHO O ENFERMEDAD DE UHL

It appears due to a partial or massive progressive replacement of the myocardium by fibroadipose or adipose tissue.
