Feature-tracking computed tomography left atrial strain and long-term survival after transcatheter aortic valve implantation
Authors' conclusion
PALS assessed with FT MDCT is independently associated with all-cause mortality after TAVI.
Study context
- Population
- Patients with severe aortic stenosis (AS) undergoing transcatheter aortic valve implantation (TAVI) with pre-TAVI multi-detector computed tomography (MDCT) suitable for feature-tracking (FT) left atrial (LA) strain assessment
- Participants
- 376 patients
- Exposure
- PALS quartiles and all-cause mortality after TAVI
- Outcome
- All-cause mortality
- Follow-up
- Median 45 (22-68) months
