Abstract

One year after aortic bioprosthetic valve replacement with a 23-mm Epic bioprosthesis (St. Jude Medical, St. Paul, MN) with concomitant coronary artery bypass grafting, early valve degeneration with leaflet calcification and stiffening was documented in a 61-year-old man. A possible reason for this extremely early deterioration could not be identified, although a xenograft reaction could be a plausible hypothesis. Consequently, a successful redo aortic valve replacement with a 21-mm Magna Ease (Carpentier-Edwards, Irvine, CA) was performed.

摘要

一名 61 岁男性患者在接受 23 毫米 Epic 生物瓣（美敦力，明尼苏达州圣保罗）行主动脉瓣置换术，并同期行冠状动脉旁路移植术后 1 年，发现早期瓣膜退化，伴有瓣叶钙化和僵硬。尽管异种移植反应可能是一个合理的假设，但无法确定这种极早期恶化的原因。因此，成功地对该患者进行了 21 毫米 Magna Ease（爱德华兹生命科学，加利福尼亚州欧文）再次主动脉瓣置换术。
