AI Article Synopsis

  • International guidelines recommend assessing frailty before Transcatheter Aortic Valve Implantation (TAVI), but there's no standard method to do so; this study used the Edmonton Frail Scale (EFS) to evaluate frailty status in patients.
  • In a study of 357 TAVI patients, higher EFS scores (indicating greater frailty) were linked to longer hospital stays and increased mortality rates within 30 days to 4 years post-procedure.
  • The findings suggest that the EFS is an effective tool for identifying frailty in TAVI patients and could guide clinical decisions to improve patient outcomes and reduce the risk of complications.

Article Abstract

Background: International guidelines for the management of valvular heart disease recommend frailty assessment prior to Transcatheter Aortic Valve Implantation (TAVI), however there is no consensus how to assess frailty. We investigated whether frailty status assessed with the Edmonton Frail Scale (EFS, range 0-17 points) relates to length of stay (LOS), short- and long-term mortality and adverse outcomes after TAVI.

Methods: In this study we included 357 patients between April 2016 till December 2018. EFS was assessed at baseline. Patients were classified into low (0-3), intermediate (4-7) or high frailty status (8-17). LOS was defined as the number of days between admission and discharge. Mortality data were obtained up to four years after TAVI. Adverse events were defined by Valve Academic Research Consortium (VARC)-2 criteria and collected <30 days after TAVI.

Results: Patients with higher frailty status had longer median LOS (days (IQR): low 5 (3), intermediate 6 (4) and high 7 (5), p < 0.001) and higher mortality: low vs intermediate vs high at 30 days 0.5%, 2.2%, 7.0% (p = 0.050), 1 year 3.7%, 10.0%, 15.2% (p = 0.052), 2 years 9.2%, 17.8%, 31.7% (p = 0.003), 3 years 17.2%, 24.0, 47.0% (p = 0.001) and 4 years 19.6%, 30.8%, 55.6% (p < 0.001). Frail patients received more often a pacemaker (2.6%, 6.6%, 13.5%, p = 0.048).

Conclusion: In clinical practice, the EFS is a useful tool to screen for frailty in TAVI patients. This tool may possibly be expanded to determine benefit versus harm-risk in these patients and whether specific pre-procedurally interventions are needed in order to reduce mortality.
