Wowsie—Never even heard of this test. Will try to get done ASAP.You should probably get your Lp(a) tested. It's a simple blood test that is often done with a cholesterol panel, such as the CardioIQ advanced lipid panel at Quest Diagnostics. It can also be ordered as a stand alone test at any major lab. It runs about $50.
Elevated Lp(a) is causal for both heart disease and valve disease. Often times when a patient presents with valve disease who is not BAV, who has not had rheumatic fever or endocarditis, it is discovered that the patient has elevated Lp(a). However, this is often over looked by cardiologists and despite it's strong association with valve disease, valve patients are often never tested for Lp(a). See link below for info on the association.
"High Lp(a) may also promote faster progression of aortic stenosis, culminating in earlier aortic valve replacement or death.
In the primary prevention setting, elevated Lp(a) is associated with several ASCVD outcomes, as well as aortic valve stenosis and cardiovascular and all-cause mortality. "

Also, you indicated that your porcine valve failed after about a year. In a study published this year, elevated Lp(a) was found to be strongly associated with early development of SVD for tissue valve patients. See link below:

If your Lp(a) is normal, you will never need to get it tested again. Unlike LDL cholesterol, Lp(a) remains almost exactly the same throughout a patient's life. There is currently one treatment which lowers it 15% to 45% for most patients, but there is a treatment which lowers it about 80% called antisense which is well into its phase 3 trial and expected to get FDA approval next year.
Thank you again.
