Brief Summary:
Transcatheter aortic valve replacement (TAVR) is a treatment alternative among high-risk elderly with aortic stenosis, however, mortality remains high. Fifty percent of patients undergoing TAVR exhibit frailty, a syndrome associated with poor survival. It is unknown whether interventions to improve frailty before TAVR (prehabilitation) will improve outcomes after TAVR. This study plans to evaluate whether simple cardiac exercise interventions to improve physical performance before TAVR improves outcomes after TAVR.

Arm Intervention/treatment
Active Comparator: Prehabilitation
Will receive 4 weeks of supervised exercised prescription before they undergo TAVR and will monitor and record, improvement if any, in the short-term physical performance battery score
Other: Prehabilitation
Supervised exercise training intervention will include three sessions per week for four weeks at a Mayo Clinic system cardiac rehabilitation facility. The Rochester, Minnesota Cardiac Rehabilitation Program will provide guidance and oversight. Modes of aerobic exercise will include treadmill walking (the primary mode of training) supplemented with non-weight-bearing activities such as stationary cycling and combination arm/leg recumbent exercise (NuStep device), as needed. Intensity will be set using Borg Perceived Exertion Scale (RPE) ratings of 12-14 (somewhat hard), keeping patients below the threshold for more than mild angina.

Placebo Comparator: Usual care
Will receive usual care
Other: Usual Care

Primary Outcome Measures :
  1. Change in Score on short physical performance battery (SPPB) test [ Time Frame: Baseline, approximately 1 year ]
