简介：摘要：经导管主动脉瓣膜置换术具有创伤性小、术后并发症和致死率较低的优势，因此该手术具有极高的治疗安全性，成为了治疗复杂高危的主动脉瓣狭窄患者的主要治疗手段，根据相关学者的研究，为复杂高危主动脉瓣狭窄患者实施经导管主动脉瓣膜置换术治疗后的情况进行随访调查，证实了该手术用于治疗的安全性和与有效性。为患者实施手术治疗的时候，需要帮助患者完善各项检查，通过多学科协同评估患者的机体状态，制定合理的治疗方案，并且为患者实施个性化的护理方案，改善患者的心肾功能。护理人员需要充分了解经导管主动脉瓣膜置换术的流程、注意事项和潜在的危险，检测患者的病情，为患者术后实施呼吸支持，维持体循环等手段，降低并发症发病率。
