Computed Tomography in the Evaluation of Early Postoperative Complications After Transcatheter Aortic Valve Replacement

Q: What is the clinical evidence from this study?

Study design: Cohort. Population: Critical aortic valve stenosis (n=70). Intervention: Asymmetric aortic valve calcification vs. Symmetrical aortic valve calcification. Primary outcome: Correlation between severity of asymmetry of aortic valve calcinosis and degree of paraprosthetic regurgitation (r=0.44, p=0.0002).

Q: What does this research mean for the field?

Asymmetric calcification of the aortic valve moderately correlates with the degree of paraprosthetic regurgitation after transcatheter aortic valve replacement. Novelty: ClaimNovelty.INCREMENTAL. Consensus alignment: ConsensusAlignment.NEUTRAL.
