The use of porcine bioprostheses has been associated with a low rate of embolic complications. The case here presented provides evidence that systemic emboli in porcine valve recipients may not necessarily be due to intracardiac or prosthetic thrombosis, but to detachment and migration of fragments of degenerated cusp tissue. Therefore, urgent assessment of xenograft function is recommended in patients with a porcine bioprosthesis who experience embolic episodes late postoperatively.
猪生物假体的使用与较低的栓塞并发症发生率相关。此处呈现的病例提供了证据，表明接受猪瓣膜置换的患者发生全身性栓塞不一定是由于心内或人工瓣膜血栓形成，而是由于退化的瓣叶组织碎片的脱落和迁移。因此，对于术后晚期发生栓塞事件的猪生物假体患者，建议紧急评估异种移植物功能。
