研究目的:

本研究旨在建立并规范针对急危重症主动脉瓣心脏病患者的急诊TAVR治疗流程;提出完整的经颈动脉入路TAVR治疗规程;开展老年重度瓣膜性心脏病优化治疗策略与持续性技术改进的研究。为老年高危复杂重度主动脉瓣心脏病领域提出完整的术前评价系统、完善手术操作方案及术后综合管理体系提供理论依据及数据支持。  

Objectives of Study:

The study aims to establish and standardize emergency TAVR treatment procedures for patients with acute and severe aortic stenosis. To propose a complete tAVR treatment protocol via carotid approach. To carry out research on optimal treatment strategy and continuous technical improvement of elderly patients with severe valvular heart disease. It provides theoretical basis and data support for proposing a complete preoperative evaluation system, improving the surgical operation plan and comprehensive postoperative management system in the field of elderly high-risk severe aortic stenosis.

(3) 腹或胸主动脉闭塞或严重狭窄、主动脉瘤、主动脉夹层病史;
(4) 主动脉弓或降主动脉不稳定性动脉硬化斑块或严重动脉硬化[增厚(> 5 mm)、突出或溃疡]、降主动脉血栓;
(5) 胸部解剖异常导致器械同轴操作困难(例如漏斗胸);
(6) 主动脉根部解剖结构复杂(例如主动脉瓣严重钙化、二叶式主动脉瓣患者、主动脉弓角度异常、既往曾行二尖瓣瓣膜置换术的患者),经心脏团队讨论,判断经颈动脉入路TAVR对器械操控性更好。


3. 优化治疗策略研究:

Inclusion criteria

1. Inclusion criteria for emergency TAVR treatment
(1) New York Heart Function (NYHA) grade IV;

数据采集和管理(说明:数据采集和管理由两部分组成,一为病例记录表(Case Record Form, CRF),二为电子采集和管理系统(Electronic Data Capture, EDC),如ResMan即为一种基于互联网的EDC:

病人的个体数据由各中心独立收集后通过电子数据收集(EDC)系统进行录入,其录入的模板已事先设计并分发于各中心。大多数数据都是临床研究中常见的数据。该研究具有多重的质量控制体系。各中心应妥善保管数据录入密匙,经通过培训的医学人员完成数据纳入。EDC 系统具有初步的质量监管功能,此外各中心分配有一个数据质量监管员。注册研究管理委员会将定期对于各中心纳入数据进行抽样检查。各中心将会事先接受数据纳入的培训,其中包括了对于患者事件及终点的明确定义。所有的新资料和信息会第一时间传递给研究相关人员。

Data collection and Management (A standard data collection and management system include a CRF and an electronic data capture:

Patient information is collected for research purposes only and confidentiality is strictly implemented. The clinical data of the participants is collected by each research center and entered into Electronic Data Capture (EDC) system in a previously agreed uniform format. The majority of the gathered information are common clinical data. This clinical trial has multiple quality control systems. The clinical data is strictly confidential and is gathered by trained medical professionals at each research center. In addition, each research center has a medical profesional monitoring the quality of the gathered data and data inspections are conducted by the Data Management Committee regularly. Before the beginning of the clinical trial, detailed training regarding data collection is also conducted at each research center. All first-hand data is uploaded and shared by the researchers as soon as possible.
