Impact of Pressure Recovery Adjustment on Aortic Valve Area Classification of Disease Severity in Transcatheter Aortic Valve Replacement Patients
Authors' conclusion
Adjusting calculated AVA for PR resulted in a reclassification of a significant number of adult patients from severe to moderate aortic stenosis.
Study context
- Population
- Adults (≥18 years old) with severe aortic stenosis who underwent transcatheter aortic valve implantation (TAVI) at a quaternary-care academic centre, October 2013–February 2021
- Participants
- 342 adults
- Exposure
- Pressure recovery (PR)-adjusted vs unadjusted aortic valve area (AVA) for aortic stenosis severity grading
- Reclassifiedn = 81reference
- Outcome
- Reclassification from severe to moderate aortic stenosis (AVA >1.0 cm²) with PR-adjusted AVA
