摘要(Abstract):
目的 通过分析Micra无导线起搏器的应用和随访结果,探讨无导线起搏器在临床应用中的安全性和有效性。方法 采用前瞻性队列研究,选取2019年12月至2021年1月于首都医科大学附属北京安贞医院行Micra无导线起搏器植入的患者,记录患者的临床基线资料、手术时间、放射线曝光时间、并发症、术后3个月内的随访情况、起搏参数以及生活质量评分。结果 共入选65例Micra植入患者,平均年龄(73.6±9.5)岁,其中男45例(69.2%)。所有患者均成功植入Micra无导线起搏器,平均手术时间(42.56±5.83)min,放射线曝光时间(8.71±2.12)min,出院前和术后3个月的平均阈值分别为(0.51±0.29)V@0.24 ms和(0.48±0.16)V@0.24 ms,感知分别为(11.9±4.3)mV和(12.3±3.3)mV,阻抗分别为(815±212)Ω和(795±159)Ω;1例术后出现伤口愈合延迟,1例出现少量心包积液,1例阈值偏高,均未予特殊处理,预后良好;未见穿刺部位血肿、动静脉瘘、感染、器械移位和心脏压塞等发生;术后有8例进行了3.0 T核磁共振成像检查,无不良反应发生;术后3个月的健康调查简表心评分较术前明显升高,其中生理职能、精力、社会功能、情感职能方面差异均有统计学意义(均P<0.05)。结论 Micra无导线起搏器植入手术操作相对简便、微创,手术成功率高、时间较短,安全性高,起搏参数稳定,提升了患者生活质量。
