Aortic stenosis is the most common form of valvular heart disease in the Western world and until recently, surgical aortic valve replacement has been the only treatment available for patients with this disease that has been shown to improve both symptoms and survival. Transcatheter aortic valve replacement has emerged as a new therapy for patients with severe aortic stenosis who are poor surgical candidates due to their elevated surgical risk. As longer follow up is obtained and improvements continue to be made in the current available prostheses, transcatheter aortic valve replacement will likely become a treatment alternative for high-risk patients with severe aortic stenosis.
在西方世界，主动脉瓣狭窄是最常见的心脏瓣膜疾病形式，直到最近，外科主动脉瓣置换术一直是这种疾病患者唯一经证实可改善症状并提高生存率的治疗方法。经导管主动脉瓣置换术已成为一种新的治疗方法，适用于因手术风险高而不适合手术的严重主动脉瓣狭窄患者。随着随访时间延长以及现有假体不断改进，经导管主动脉瓣置换术可能会成为高危严重主动脉瓣狭窄患者的一种治疗选择。
