右心室起搏器或除颤器导线
经静脉心血管植入型电子器械(起搏器或ICD)导线长期穿过三尖瓣口置入右心室(心尖部或室间隔)。
定义
经静脉心血管植入型电子器械(起搏器或ICD)导线长期穿过三尖瓣口置入右心室(心尖部或室间隔),跨越三尖瓣对合平面,可能因机械性干扰或瘢痕性纤维化导致不同程度的三尖瓣关闭不全,但无活动性感染或导线功能障碍证据 [G7-05] [G7-03]。
严重程度标准
- 严重程度分级:单一级别。代表心内导线无心内膜炎或严重器械功能障碍的解剖与生理基线状态。
-
导线相关三尖瓣关闭不全(CIED相关TR)定量:
- 轻度三尖瓣关闭不全的定量标准(依据ASE/EACVI与JACC Cardiovasc Imaging共识审查 [G7-05, Tabla 1] 及ESC/EACTS 2025指南 [V1, Tabla 9]):
- 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。
- 流行病学患病率:接受右心室导线植入的患者中有 15–40 % 证实出现新发或加重的三尖瓣反流束 [G7-05]。
- 阴性标准:导线上完全无赘生物或疣状赘生物附着,且无菌血症或全身炎症反应体征 [G7-03]。
