Abstract：
1.Contrast-free transfemoral transcatheter aortic valve replacement was performed in a case series of 4 patients using a novel technique guided by transthoracic echocardiography under conscious sedation.2.Outcomes including mortality, incidence of cerebrovascular accident, or heart block were comparable with those of the traditional approach while minimizing the risk of renal injury.3.This approach gives the heart team a technically feasible, safe, and effective option to minimize the risk of renal injury, the need for transesophageal echocardiogram, and higher levels of sedation.
摘要：
1.在有意识的镇静下，使用经胸超声心动图引导的新技术，对4例患者进行了无对比剂经股动脉经导管主动脉瓣置换术。结果包括死亡率，脑血管意外的发生率，或心脏传导阻滞与传统方法相当,同时将肾损伤的风险降至最低3.这种方法使心脏团队在技术上可行，安全,和有效的选择，以尽量减少肾损伤的风险，需要经食管超声心动图,和更高水平的镇静。
