三尖瓣感染性心内膜炎
右侧三尖瓣心内膜感染(在静脉吸毒者、中心静脉置管携带者或长期血管通路患者中主要由金黄色葡萄球菌引起)。
定义
右侧三尖瓣心内膜感染(在静脉吸毒者、中心静脉置管携带者或长期血管通路患者中主要由金黄色葡萄球菌引起),其特征是在三尖瓣叶上增生粗大的败血性赘生物伴瓣叶或腱索破坏,导致三尖瓣关闭不全及反复发作的败血性肺栓塞梗死/脓肿 [C3] [G7-14]。
严重程度标准
- 轻度(L):有效反流孔面积(EROA)< 0.20 cm²(< 20 mm²);反流容积(RV)< 30 mL/次;缩流颈宽度(VC)< 3.0 mm;彩色多普勒反流束面积 < 5 cm² [V1] [V3]。
- 中度(M):EROA 0.20–0.39 cm²(20–39 mm²);RV 30–44 mL/次;缩流颈(VC)3.0–6.9 mm;反流束面积 5–10 cm² [V1] [V3]。
- 重度(G):EROA ≥ 0.40 cm²(≥ 40 mm²);RV ≥ 45 mL/次;缩流颈(VC)≥ 7.0 mm;反流束面积 > 10 cm²;肝静脉出现收缩期反向逆流 [V1] [V3]。
- 右侧心内膜炎赘生物大小标准:根据ESC 2023指南 [C3, Sección 12.1, Tabla 16],赘生物大小 > 20 mm 伴反复败血性肺栓塞构成三尖瓣手术(修复或置换)的正式指征。
