研究目的:

主动脉瓣狭窄(aortic stenosis, AS)是老年人群中常见的心脏瓣膜疾病,随着人口老龄化,其患病率逐年上升。近年来,经导管主动脉瓣置换术(trans-catheter aortic valve implantation, TAVI)在国内逐渐推广,成为中高危重度主动脉瓣狭窄患者的重要治疗方式。然而,TAVI术后早期死亡风险仍然存在,且风险预测模型尚不完善。 既往研究提示,右心室功能(right ventricular function, RVF)受损是TAVI术后早期不良预后的重要危险因素。三尖瓣环收缩期位移(tricuspid annular plane systolic excursion, TAPSE)是评估右心室收缩功能的简便超声指标。本研究拟通过回顾性分析我中心 2022 年至 2024 年接受 TAVI 的 21 例患者,探讨基线TAPSE对TAVI术后30天死亡率的预测价值,以期为临床风险分层和围术期管理提供循证依据。  

Objectives of Study:

Aortic stenosis (AS) is a common valvular heart disease among older adults, and its prevalence is increasing with population ageing. In recent years, transcatheter aortic valve implantation (TAVI) has been progressively adopted domestically and has become an important treatment option for intermediate- to high-risk patients with severe AS. However, the risk of early post-TAVI mortality remains, and current risk-prediction models are still suboptimal. Prior research indicates that impaired right ventricular function (RVF) is a significant risk factor for early adverse outcomes after TAVI. Tricuspid annular plane systolic excursion (TAPSE) is a simple echocardiographic index for assessing right ventricular systolic function. This study plans a retrospective analysis of 21 patients who underwent TAVI at our centre between 2022 and 2024 to investigate the predictive value of baseline TAPSE for 30-day mortality following TAVI, with the aim of providing evidence to support clinical risk stratification and perioperative management.
