Hi, Thanks for using the HCM.
you have mentioned as bicuspid valve, weather its a aortic valve
or other valve,
am assuming it as aortic valve, most of the cases are sporadic, few could be familial also..
possible complications are:
progressive aortic root dilation
he needs regular follow up with cardiologist for early detection of complications and treatment.
need to undergo annual CT/ MRI
to detect aortic dilatation, lipid profile
better to screen in other family members as this can be a familial also..
Hope I have answered your query. If you have any further questions I will be happy to help. Thanks get well soon
