What causes Arrhythmogenic right ventricular dysplasia (ARVD)
What causes ARVD?
ARVD appears to have a significant family history. More than 30% can report other cases within the family. Beyond that we know little to the cause.
The accelerating deterioration of the right ventricle muscle leads to increased heart failure in addition occurring changes in the heart's electrical conduction system that leads to increasingly frequent cardiac arrhythmia.
How frequently is ARVD?
ARVD was first thought to be a rare condition, but the disease has now been shown to occur in 6 of 10,000 people a year in certain populations. In some areas of the Mediterranean Sea and in the southern United States, the numbers of new cases per annum were found to be 44 per 10,000. The condition is fairly certain under-diagnosed.
We expect that ARVD is responsible for 3-4% of all cases of death in sports, and 5% of cases of sudden cardiac death among people younger than 65 years. The condition can occur in any age, but usually in young or middle aged. The average age is just over 30 years. There are three times more men who get the condition than women.
