Question 12#

With regard to ARVC:

A) The diagnosis can be confirmed on the basis of MRI findings alone
B) All patients with a confirmed diagnosis will need an ICD
C) It is normally autosomal dominant
D) Genetic tests are positive in most cases
E) A and C

Correct Answer is C

Comment:

To confirm the diagnosis two major, one major and two minor, or four minor criteria are needed, and therefore a diagnosis cannot be made solely on cardiac MRI. Asymptomatic patients with mild disease do not require an ICD. The condition is usually autosomal dominant, but currently genes are only identified in approximately 30% of cases.
