Does not support clinical use of ethanol pretreatment; leaves open synergistic strategies for bioprosthetic valve durability.
Does ethanol pretreatment reduce calcification of bioprosthetic heart valve aortic walls in animal implant models?
Ethanol pretreatment partially inhibits bioprosthetic aortic wall calcification, likely through lipid extraction and protein structure changes, but may require synergistic agents for complete prevention.
Lee et al. (1998) studied this question.
