Mechanical Wave Velocities in Left Ventricular Walls in Healthy Subjects and Patients With Aortic Stenosis
An erratum to this article was published (JACC Cardiovasc Imaging, Apr 2024 ↗)
Authors' conclusion
MWV estimation during atrial kick is feasible and demonstrates higher velocities in the lateral walls, compared with septal walls.
Study context
- Population
- Healthy subjects and patients with severe aortic stenosis (AS) undergoing high frame rate echocardiographyCMR in 42
- Participants
- 63 vs 13
- Exposure
- Healthy subjects vs patients with severe AS
- Healthyn = 63reference
- Severe ASn = 13
- Outcome
- Mechanical wave velocities (MWVs) in different LV walls at atrial kick and aortic valve closure; feasibility and reproducibility
Main finding
As reported in the abstract
MWV at atrial kick, healthy subjects
- Feasibility for atrial kick wave, all 4 examined LV walls
- >93%
- Mechanical wave velocity (MWV), inferolateral and anterolateral walls
- 2.2 and 2.6 m/s
- MWV, inferoseptal and anteroseptal walls
- 1.3 and 1.6 m/s
- Lateral vs septal walls, higher MWVs
- P < 0.05
Observational data: associations, not effects.
Further findings
Septal MWV at aortic valve closure
- Significantly higher in severe AS than in healthy subjects
