[ARVD-FORUM] Pathological difficulties to distinguish lipomatosis from true ARVD. Dr Lorin de la Grandmaison

[ARVD Symposium]

English - Spanish

Dear colleagues,
Significant fat infiltration of the right ventricle which can be found in
autopsy cases always raises the question of a possible underlying ARVD. The
difficulty is that such right ventricular lipomatosis can be associated with
small foci of fibrosis, especially if there is a small degree atheromatous
stenosis, an obesity or a chronic alcohol disease. In such cases, what are
the pathological criteria useful to make the differential diagnosis? And do
you know if such lipomatosis can induce lethal arrhythmias even if is not a
true ARVD?

I thank you in advance for your answer.

Estimados colegas:
La infiltracion adiposa significativa del ventriculo derecho que puede
encontrarse en los casos de autopsia siempre hace surgir la cuestion de una
posible DAVD subyacente. La dificultad es que tal lipomatosis del ventriculo
derecho puede asociarse con pequenios focos de fibrosis, especialmente si
hay un grado menor de estenosis ateromatosa, obesidad o alcoholismo cronico.
En tales casos, cuales son los criterios patologicos utiles para hacer un
diagnostico diferencial? Y saben si tal lipomatosis puede inducir arritmias
letales incluso si no es verdadera DAVD?

Desde ya les agradezco su respuesta.

Saludos cordiales,
