Association of Lipoprotein(a) With Severe Degenerative Aortic Valve Stenosis Open
Lp(a) levels >100 mg/dL were significantly associated with risk for severe degenerative AS and subsequent AVR, regardless of the baseline severity of AS. Such associations were not observed in other etiologies of severe AS.
