Coronary Access After Supra-Annular THV Implantation

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.
