This is my first post in this forum. Yesterday, my surgeon said he is pretty sure my AV is bicuspid. He will confirm in three weeks when he replaces my valve. I then mentioned my Uncle Bob who has had 2 AVR in the last 20 years and my Uncle Paul who died suddenly in his mid 50s without any history of arterial heart disease. As well, there is my younger brother who has a heart murmur. Dr Spann said that this is just the type of distribution that one would expect to see and that there are probably more cases that have not been recognized. If the valve is, indeed, bicuspid, how do you tell all of your cousins (and I have a lot of them) that they need to have their hearts checked for a potentially fatal genetic defect without causing an uproar? My first thought is that I should enlist the assistance of my Uncle Harold who has become the family center. I would appreciate hearing your suggestions.
