研究概览

简要总结

To determine the optimal technique and equipment for selective coronary engagement specifically following Evolut THV implantation using commissural alignment.

详细描述

Patients will undergo elective transfemoral TAVR with the Evolut THV. The operators will attempt to selectively engage both the right and left coronary arteries through standardized angiographic views. The CCI-CIC CoreLabs will adjudicate angiographic views, post-TAVR CT scan, and determine if the coronaries were selectively engaged. Catheter choice, adjunctive tools if needed (e.g guide extension, wires etc) and engagement technique will be at the discretion of the operator. All images and fluoroscopic views will be anonymized, saved and imported to the CCI-CIC Angiographic and CT CoreLabs.

Statistical analysis

Patient baseline and outcome data will be presented as mean and standard deviation (SD) for normally distributed variables, median and interquartile range (IQR) for non-normally distributed variables, and frequency and proportion for categorical variables.

入选标准

  • Patients undergoing elective transfemoral TAVR with the Evolut THV (Medtronic, Minneapolis, MN, USA).
  • Written informed consent to participate in the study.

排除标准

  • Hemodynamic or respiratory instability immediately prior to TAVR or during TAVR.
  • Advanced chronic kidney disease, defined as a GFR <30 ml/min.

  • Prior PCI of the left main or right coronary ostium

结局指标

主要结局

The ability to selectively engage and obtain diagnostic epicardial coronary angiography images from the right and left coronary ostia

时间窗: Immediately post-TAVR

Coronary engagement will be classified as: 1. Partially successful if non-selective engagement is achieved (catheter is unable to be placed in the coronary ostia) and there is adequate opacification of the coronary vessels. 2. Successful if selective engagement is achieved with placement of the coronary catheter in the coronary ostia and adequate opacification of the coronary vessels. 3. Unsuccessful if engagement is not possible and there is insufficient opacification of the coronary vessels.

次要结局

  • Total contrast use (ml) from catheter insertion to selective coronary engagement.(During TAVR procedure)
  • Total number and types of wires and catheters used.(During TAVR procedure)
  • Description of type of technique utilized to achieve selective coronary engagement.(During TAVR procedure)
  • Type of wire and catheter used for successful right and left coronary engagement(During TAVR procedure)
  • Total fluoroscopic time (mins) from catheter insertion to selective coronary engagement.(During TAVR procedure)
