Valvular Heart DiseaseRelation of Frailty to Outcomes After Transcatheter Aortic Valve Replacement (from the PARTNER Trial)
Section snippets
Methods
The design and initial results of the PARTNER trial have been published previously.15, 16 The PARTNER trial enrolled patients with severe symptomatic AS into 2 cohorts: those at high surgical risk (cohort A) and those considered inoperable because of severe coexisting conditions (cohort B). Patients in cohort B with a suitable iliofemoral vessel were randomized to transfemoral TAVR with the Edwards-Sapien heart valve system (Edwards Lifesciences, Irvine, California) or to standard medical care.
Results
Of the 244 patients included in this analysis, overall, median gait speed was 0.38 m/s (IQR 0.23 to 0.64 m/s), median serum albumin was 3.9 g/dl (IQR 3.6 to 4.2 g/dl), and 172 (71%) performed all ADLs independently. In men, median grip strength was 23.6 kg (IQR 17.0 to 28.3), and in women, median grip strength was 12.2 kg (IQR 10.0 to 15.7; Table 1) The median frailty score was 5 (IQR 3 to 7). Accordingly, for the purposes of this study, 134 (120 cohort A and 14 cohort B) participants with a
Discussion
The present report, drawn from a cohort of 244 patients with severe symptomatic AS who underwent TAVR at 3 US sites, evaluated the association between frailty as estimated by the composite of gait speed, grip strength, ADLs, and albumin and outcomes after TAVR. We found that at 30 days, the rate of mortality and major complications did not differ between the frail and nonfrail groups; however, at 1 year, compared with those with a frailty score less than the median value, those with a frailty
Disclosures
The PARTNER trial was funded by the Edwards Lifesciences (Irvine, CA), and the protocol was developed collaboratively by the Sponsor and Steering Committee. The present analysis was designed and completed by the authors through the PARTNER Publications Office, which is co-located at the Columbia University Medical Center/The Cardiovascular Research Foundation and The Cleveland Clinic and supported by an unrestricted grant from the Edwards Lifesciences, administered by the Medstar Health
