Transaortic valve replacement, complications and validation of a protocol in ICU

Aortic stenosis(AS) is the most prevalent valvular disease (incidence 2% over 65years). Valvular area decreases 0.3m/s/y, transvalvular gradient (7mmHg/y) and blood speed(0.3m/s/y) increases with age. AS treatment can be medical or surgical:heart valve replacement surgery or percutaneous placement of an aortic endoprothesis(TAVR) in patients with high perioperative risk.TAVR is beneficial and improves their expectative and quality of life (QOL) compared with medical treatment.
