NIHR Signal Transcatheter aortic valve implantation may be an option for patients with aortic stenosis at lower surgical risk
Transcatheter aortic valve implantation (TAVI), the less-invasive procedure, may be associated with a reduced risk of death and stroke for up to two years when compared with surgical aortic valve replacement for adults with severe narrowing of the aortic valve, irrespective of the level of surgical risk. TAVI is already an established procedure for those unsuitable for surgery or at high risk. This meta-analysis evaluated seven trials comparing 8,020 adults treated with one of these procedures ...
NIHR Signal Aortic valve implantation without open surgery has short term benefits
For people with severe symptomatic aortic stenosis, implanting an aortic valve by guiding it into place through the blood vessels rather than by open heart surgery improves survival at two years. This review pooled data from four major trials of different catheter-based devices in people who were eligible for either treatment. It found the less invasive approach improved survival compared to open heart surgery at two years, when the results for all surgical risk categories were combined. The le...
