Hi Dr Nocturne,
What you described is a very likely cause. I did a CT scan 3.5 years ago. My calcium score was 777,mainly on the left side: Left Main 193, LAD 473, LC 106. My cardiologist did not ask me to do angiogram because she thought it's invasive.
I haven't had Lp(a) tested but I will. I would appreciate it if you could share more on the topic. Thank you very much!

Ha ha! Doctor Nocturne! I'm the only adult of four living in this house who is NOT a doctor!
Calcium score of 777 at age 50? Well hot damn! That puts you right up in the 99th percentile for age -- just like me. You lucky dog, you!
Considering your otherwise great numbers (and assuming they have always been so), I'd say there is a very good chance that you have astronomically high Lp(a), like me. I'd get that looked into ASAP. Your docs probably never looked at it because they either didn't know anything about it or just don't like feeling impotent because there's really not much that can be done about high Lp(a) (Agian will disagree -- he is partly correct but his methods involve utilizing medication that is prohibitively expensive here in the USA and also niacin, which when I took it seems to have rocketed my fasting blood glucose into prediabetes).
The hopeful news is that there is a medication being developed by Ionis Pharmaceuticals (currently in stage 3 trials) that can lower Lp(a) by over 90%. We'll see how the situation in the States limits that med to the rich and famous, if it even passes through the FDA.
Are you absolutely sure that your valve is bicuspid? There is great and growing evidence that high Lp(a) increases one's odds of developing AVS. My own valve is noted as being tricuspid (normal) but "acting" bicuspid -- tricuspid morphology but functionally bicuspid or something like that.
If your Lp(a) is high, you might consider looking at your genetics (as Lp(a) is almost entirely determined by genetics -- it doesn't care what you eat or how much you exercise or how much you weigh). I have two copies of the faulty allele LPA rs 10455872, which results in sky high Lp(a) levels and about five times the normal chance of developing AVS. I learned this on my own by getting a 23andme genetics test done and from information gleaned at the Lp(a) Foundation website.
Here are a few things to look at:

The most recent and most positive study regarding AVR and relative lifespan I have found to date:

The most positive study on long term survival with high CAC I have found to date:
https://www.sciencedirect.com/science/article/pii/S0735109707019328
If you want any help interpreting any of that, I'd be happy to. I will say that there are studies out there with less positive conclusions -- I'm just offering you the happy ones.
In a nutshell, if these studies are to be believed, your high CAC score shaves less than 5 years off of your life on average, and if you had AVR right now you'd have about a 75% chance of living at least another 20 years.
Get your Lp(a) checked, and if it's very high and you have kids, have them get theirs checked too. Mine is a monstrous 160+ (where 12 or so is average and 50 is "extremely high risk"), and my 4 kids are 50, 50, 100, and unknown. If Ionis' drug works, I want them on it before they start having to deal with this nonsense.
