CoreValve Evolut Pro Prospective Registry
Purpose
The primary objective of this study is to evaluate the real-world performance of the CoreValve Evolut PRO transcatheter aortic valve, including leaflet function, in a prospective observational registry.
Condition
- Aortic Stenosis
Eligibility
- Eligible Ages
- Over 50 Years
- Eligible Genders
- All
- Accepts Healthy Volunteers
- No
Inclusion Criteria
- Symptomatic severe aortic stenosis 2. Intermediate, high or extreme surgical risk 3. The institutional Heart Team determines that transcatheter aortic valve replacement with an Evolut Pro device is appropriate
Exclusion Criteria
- Subject unable or unwilling to give informed consent 2. For subjects in the CT arm only, renal function precluding the administration of iodinated contrast for cardiac CT (eGFR < 30 ml/min/1.73m2). An exception to this exclusion criterion is made if the subject is established on renal replacement therapy and is therefore able to receive intravenous iodinated contrast media. 3. Pregnancy or intent to become pregnant prior to completion of all protocol follow-up procedures

Arm Groups
Arm | Description | Assigned Intervention |
---|---|---|
CT Cohort | Compare the rate of ≥mild PVL in patients with none/mild versus moderate/severe LVOT calcification. Comparison of the rate of PPM implantation in patients with none/mild versus moderate/severe LVOT calcification. Determine how the Evolut PRO conforms to LVOT calcification. Compare the impact of LVOT calcification on the implantation depth of the Evolut PRO. Analyze the interaction and geometry of the Evolut PRO in patients with moderate/severe LVOT calcification. Assess for leaflet thickening, subclinical leaflet thrombosis and/or restricted leaflet motion 30-60 days after TAVR. |
|
Non-CT Cohort | Compare the rate of ≥mild PVL with the Evolut PRO with a propensity score matched cohort of historical control subjects who underwent TAVR with the Evolut R and/or CoreValve within the MedStar Health System. Determine which features of LVOT calcification (volume, location relative to aortic annulus and sinuses, prominence into the LVOT lumen) predict ≥mild PVL. Determine which features of LVOT calcification (volume, location relative to aortic annulus and sinuses, prominence into the LVOT lumen) predict PPM implantation. |

Detailed Description
The CoreValve Evolut PRO transcatheter aortic valve was approved by the FDA in March 2017 to treat patients with symptomatic severe aortic stenosis at high or extreme risk for open heart surgery, and in July 2017 for intermediate risk patients. This latest generation device features an outer wrap to improve annular sealing and reduce paravalvular leak. In this observational study, baseline demographic and imaging characteristics, procedural details and clinical outcomes of patients undergoing transcatheter aortic valve replacement with the CoreValve Evolut PRO will be prospectively collected into a registry database. The institutional Heart Team will select patients according to standard practice.
