In this pilot study, investigators aim to identify patients undergoing TAVR who are at elevated risk for adverse clinical events due to decreased exertional capacity and physical deconditioning. Investigators aim to determine if monitored pre-procedural physical therapy is safe in these patients. Lastly, investigators aim to assess the efficacy of prehabilitation

1. to improve physical functioning by the time of TAVR and to sustain benefit through 30 days post-procedure; and
2. to determine its effect on post-procedural length-of-stay, clinical outcomes, and quality of life.

Inclusion Criteria:

• Subject must be ambulatory (with or without an assist device)
• Subject has severe aortic stenosis and is felt an appropriate candidate for TAVR by the Heart Team.
• Subject requires 6.0 seconds or longer to complete a 15ft walk test
• Subject must be able to move between sitting and standing without assistance from another person.
• Subject has adequate iliac and femoral arterial anatomy to allow for TAVR via transfemoral access
• Subject is 18 years of age or greater
• Subject is willing to give consent and participate in the study

Exclusion Criteria:

• Subject is incapable of following instructions
• Subject is unable to meet the minimum required physical therapy visits
• Subject has other medical conditions rendering it unsafe, in the opinion of the Principal Investigator and physical therapy staff, to perform a 6 Minute Walk Test or physical therapy conditioning prior to TAVR
• Subject has significant severe un-revascularized epicardial coronary disease.

All individual participant data defined in the protocol will be collected during trial participation and entered in a secured Electronic Data Capturing System. All data shared or copied shared will only occur after complete deidentification. Participant data will be made available for Annual Data Safety Management Board (DSMB) committee review. The Study Protocol, Informed Consent Form, and applicable Case Report Forms will be available.
