Assessment of paravalvular regurgitation after transcatheter aortic valve replacement using 2D multi-velocity encoding and 4D flow cardiac magnetic resonance
Authors' conclusion
Two-dimensional multi-venc and 4D flow produce an accurate quantification of PVR after TAVR.
Study context
- Population
- Patients 1 month after transcatheter aortic valve replacement (TAVR), assessed for paravalvular regurgitationmean age 80 ± 5 years, 9 men
- Participants
- 21 patients
- Exposure
- 2D multi-venc and 4D flow cardiac magnetic resonance (CMR) vs standard 2D flow CMR
- Outcome
- CMR-derived regurgitant fraction (RF) of paravalvular regurgitation (PVR)
- Follow-up
- 1 month after TAVR
