Prevalence of the disease in the general population
A recent study, aiming at identifying cardiac cause of death in
otherwise negative medico-legal autopsies, revealed that in 1,000
adults under 65 years of age, who suffered a sudden death, 50 (5%)
were affected with ARVD, although they had no previous cardiac
symptoms (Loire & Tabib, 1996).
On the other hand, a preliminary epidemiological study conducted in
NorthEast Italy indicated that the prevalence of clinically manifested ARVD
cases is probably higher than 6 on 10,000 inhabitants (Rampazzo et al., 1994).
Therefore, the disease is more frequent thant it was believed in the past.
