Association between lipoprotein(a) and structural degeneration of bioprosthetic aortic valves: A systematic review and meta-analysis.
BACKGROUND Structural valve degeneration (SVD) remains a major limitation of bioprosthetic aortic valves (bAVs). Lipoprotein(a) [Lp(a)] is a genetically determined cardiovascular risk factor implicated in native aortic valve calcification, but its role in bioprosthetic valve degeneration remains incompletely understood...
