Does transcatheter aortic valve replacement improve functional outcomes in patients with low-flow severe aortic stenosis?
Despite low flow being an independent predictor of increased long-term mortality, transcatheter aortic valve replacement is supported in these patients due to high procedural success and functional improvement.
LF is a common finding within the aortic stenosis population and, in contrast to LV ejection fraction or mean pressure gradient, an independent predictor of all-cause and cardiovascular mortality. Despite increased long-term mortality, high procedural success and excellent functional improvement support transcatheter aortic valve replacement in patients with LF severe aortic stenosis.
Mangner et al. (Fri,) studied this question.
