Koh JQS, Rahim NBM, Sng EL, et al. - Since there exist no investigations assessing comprehensive predictors of transcatheter aortic valve implantation (TAVI) results encompassing frailty evaluations in a South-East Asian cohort, researchers explored frailty indices that predicted prolonged index hospitalization post-TAVI. All patients who had TAVI in a tertiary cardiac center and comprehensively evaluated for frailty at baseline were incorporated in a registry in this longitudinal single-center cohort. On multivariate linear regression, the independent baseline predictors of index hospitalization span were preoperative hemoglobin, preoperative atrial fibrillation and 5-meter walk test (5MWT). This work represents the first comprehensive frailty evaluation in a South-East Asian cohort wherein 5MWT was identified as a significant predictor of prolonged index hospitalization. To optimize patient selection for TAVI, consideration may be given to this simple as well as effective frailty evaluation index.
