A STEP for Patients Prior to Undergoing TAVR: A Pilot Study — STEP  

Aortic Valve Stenosis Clinical Trial

Official title:
A Supervised TAVR Exercise Program (STEP) for Patients Prior to Undergoing Transcatheter Aortic Valve Replacement (TAVR): A Pilot Study

Clinical Trial Summary

The aim of this pilot study is to establish whether a Supervised TAVR Exercise Program (STEP) can safely improve the frailty status in patients with symptomatic severe aortic valve stenosis prior to undergoing transcatheter aortic valve replacement (TAVR).

Clinical Trial Description

TAVR is an approved alternative therapy for patients with severe aortic valve stenosis who are deemed inoperable or high-risk for surgical aortic valve replacement (SAVR). Despite a very high procedural success rate (>95%), mortality rates after TAVR at 1- and 2-year follow-up remain ≥25% and ≥34%, respectively. It is becoming increasingly evident that frailty, as a clinical syndrome, has a large impact on this long term mortality. In a study by Green, et al. frailty status was independently associated with increased 1-year mortality (OR=3.5) after TAVR. The investigators' own retrospective analysis showed that impaired mobility and malnutrition were significantly associated with a longer hospital length of stay (5 days vs. 3 days), and increased total cost (on average, an additional $10,000 per patient). Given the phenotype of frailty is characterized by reductions in muscle mass, strength, endurance and activity level, a STEP is ideally suited to counteract these impairments. This pilot study aims to establish whether a STEP can safely improve the frailty score in patients with symptomatic severe aortic valve stenosis prior to undergoing TAVR.

This single-center pilot study will be conducted in partnership between Heart Care Midwest (HCMW), OSF St. Francis Medical Center (OSF SFMC), and University of Illinois College of Medicine at Peoria (UICOMP). UICOMP Center of Outcomes Research will provide analytical support. The study will be funded by an operational research grant from OSF SFMC. ;
