  Transcatheter aortic valve replacement (TAVR) has become a mainstream in the treatment of aortic stenosis since the initial procedure in 2002. Increasing operators' experience and improvement of the technique have resulted in a drastic reduction in complications following TAVR in patients with lower surgical risk. In parallel, the procedure was considerably simplified, with a routine default approach including conscious sedation in the catheterization laboratory, percutaneous femoral approach, radial artery as the secondary access, prosthesis implantation without predilatation, left ventricle wire pacing and early discharge. This approach has been shown to be safe and reduce procedure time, length of stay, and overall cost for hospital systems. The minimalist care pathway avoids general anesthesia, shortens procedure time and length of stay, and reduces cost without changing mortality or readmission rates at 30 days. However, simplified TAVR must be accompanied upstream by a rigorous selection of patients who can benefit from a minimalist procedure in order to guarantee its safety. There is a continued need for data regarding patient risk stratification, valve selection, and discharge strategy as TAVR becomes increasingly common.
