The primary objective of this study is to determine the efficacy, safety and feasibility of next day discharge home in patients undergoing balloon-expandable transfemoral TAVR utilizing the Vancouver 3M Clinical Pathway in low, medium, and high volume North American centres.

Inclusion Criteria:

Patients with severe symptomatic aortic stenosis undergoing elective transfemoral TAVR with a balloon expandable transcatheter heart valve

1. Considered at increased surgical risk by the Multidisciplinary Heart Team.
2. Informed written consent

Exclusion Criteria:

1. Non -cardiovascular co-morbidity reducing life expectancy to < 3 years
2. Any factor precluding 1 year follow-up
3. Inadequate CT image acquisition to perform area-based annular CT sizing, exclude adverse root features, and determine a coaxial valve deployment angle (CT is not required for valve-in-valve procedures)
4. Predicted inability to perform uncomplicated percutaneous vascular access and closure
5. Iliofemoral diameter < 6 mm for SAPIEN XT or <5.5 mm for SAPIEN 3 (measured at or above the mid-femoral head)
6. Inpatient (unless clinically stable, mobilizing at baseline, and primarily in hospital for logistical reasons.
7. Significant communication barrier(s) that interfere with ability to follow peri-procedural and discharge instructions
8. MMSE < 24/30 (unless language barrier or limited formal education), 5-metre gait > 7 seconds (unless chronic mobility impairment not affecting ability to perform ADLs), and ADL < 6/6
9. Insufficient social support to facilitate next day discharge
10. Airway unfavourable for emergent intubation
11. Inability to lay supine without conscious sedation or general anesthetic
12. Not receiving a balloon expandable transcatheter heart valve
