Transcatheter aortic valve implantation (TAVI) has become an effective treatment option for patients with severe aortic stenosis and high surgical risk or contraindications for surgical aortic valve replacement. Most of the currently available prostheses employ either balloon-expandable or self-expandable designs. Presently, there is a paucity of data directly comparing these two widely used prosthesis types. Forthcoming trials will reveal whether newer designs of both technologies translate into fewer complications and better outcomes, with expansion of TAVI indications. This manuscript reviews features and clinical outcomes of balloon- and self-expanding prostheses, summarising current data from registries and trials.
经导管主动脉瓣植入术（TAVI）已成为严重主动脉瓣狭窄且手术风险高或有外科主动脉瓣置换术禁忌证患者的有效治疗选择。目前大多数可用的人工瓣膜采用球囊扩张式或自膨胀式设计。目前，直接比较这两种广泛使用的人工瓣膜类型的数据很少。随着TAVI适应证的扩大，即将进行的试验将揭示这两种技术的更新设计是否能减少并发症并带来更好的结果。本文回顾了球囊扩张式和自膨胀式人工瓣膜的特点及临床结果，总结了来自登记处和试验的当前数据。
