A pregnant patient is incidentally found to have a bicuspid aortic valve. What is the recurrence risk implication for her fetus?
-
A
No increased risk as bicuspid aortic valve is not heritable
-
B
Approximately 9-10% risk of the fetus inheriting a left-sided obstructive lesion
-
C
50% autosomal dominant risk of exact same defect
-
D
Risk only increases if the father also has bicuspid aortic valve
