Title: Safety, Applicability and Outcome of Regular Exercise Training After Transcatheter Aortic Valve Implantation
Brief Summary: This pilot study will evaluate the effect of a rehabilitative exercise training on exercise capacity in patients after percutaneous aortic valve replacement. It will additionally evaluate the safety of such an approach and the effect on life quality. We hypothesize that regular structured exercise improves exercise capacity in these patients beyond the sole effect of the valve procedure.

A: Inclusion Criteria:

* Severe symptomatic aortic stenosis accepted for Trans Catheter Aortic Valve Replacement

* Participant able and willing to give written informed consent;
* Participant able (in the Investigator's opinion) and willing to comply with all study requirements.

Exclusion Criteria:

* Subjects may not enter the study if ANY of the following apply:
* Intervention deemed inappropriate due to co-morbidity or frailty;
* Life expectancy less than one year due to co-morbidity;
* Previous AVR or TAVI;
* Predominant aortic regurgitation (AR).
B: Inclusion Criteria:

   2. For asymptomatic patients:

      * Very severe aortic stenosis with an aortic valve area of ≤1.0 cm2 (or aortic valve area index of ≤0.6 cm2/m2), AND maximal aortic velocity ≥5.0 m/sec , or mean gradient ≥60 mmHg by transthoracic echocardiography at rest, OR
      * Aortic valve area of ≤1.0 cm2 (or aortic valve area index of ≤0.6 cm2/m2), AND a mean gradient ≥40 mmHg or maximal aortic valve velocity ≥4.0 m/sec by transthoracic echocardiography at rest, AND an exercise tolerance test that demonstrates a limited exercise capacity, abnormal BP response, or arrhythmia OR
      * Aortic valve area of ≤1.0 cm2 (or aortic valve area index of ≤0.6 cm2/m2), AND mean gradient ≥40 mmHg, or maximal aortic valve velocity ≥4.0 m/sec by transthoracic echocardiography at rest, AND a left ventricular ejection fraction \<50%.
2. Documented heart team agreement of low risk for SAVR, where low risk is defined as predicted risk of mortality for SAVR \<3% at 30 days per multidisciplinary local heart team assessment.
3. The subject and the treating physician agree that the subject will return for all required post-procedure follow-up visits.

Exclusion Criteria:

1. Any condition considered a contraindication for placement of a bioprosthetic valve (eg, subject is indicated for mechanical prosthetic valve).
2. A known hypersensitivity or contraindication to any of the following that cannot be adequately pre-medicated:

   1. aspirin or heparin (HIT/HITTS) and bivalirudin
   2. ticlopidine and clopidogrel

10. Gastrointestinal (GI) bleeding that would preclude anticoagulation.
11. Subject refuses a blood transfusion.
12. Severe dementia (resulting in either inability to provide informed consent for the trial/procedure, prevents independent lifestyle outside of a chronic care facility, or will fundamentally complicate rehabilitation from the procedure or compliance with follow-up visits).
13. Estimated life expectancy of less than 24 months due to associated non-cardiac co-morbid conditions.
14. Other medical, social, or psychological conditions that in the opinion of the investigator precludes the subject from appropriate consent or adherence to the protocol required follow-up exams.
15. Currently participating in an investigational drug or another device trial (excluding registries).
16. Evidence of an acute myocardial infarction ≤30 days before the trial procedure due to unstable coronary artery disease (WHO criteria).
17. Need for emergency surgery for any reason.
18. Subject is pregnant or breast feeding.
19. Subject is less than legal age of consent, legally incompetent, or otherwise vulnerable
20. Pre-existing prosthetic heart valve in any position.
21. Severe mitral regurgitation amenable to surgical replacement or repair.
22. Severe tricuspid regurgitation amenable to surgical replacement or repair.
23. Moderate or severe mitral stenosis amenable to surgical replacement or repair.
24. Hypertrophic obstructive cardiomyopathy with left ventricular outflow gradient.
