Comparative StudyClinical presentation and outcomes after transcatheter aortic valve implantation in patients with low flow/low gradient severe aortic stenosis.
To identify predictors of mortality, functional status, and hemodynamical changes of patients undergoing transcatheter aortic valve implantation (TAVI) for low flow/low gradient aortic stenosis (LF/LG AS). ⋯ LF/LG AS does not influence procedural mortality after TAVI but exhibits a strong impact on 6-month and 1-year mortality. The survivors, however, exhibit considerable hemodynamical and clinical improvements. Therefore, risk stratification and TAVI benefit should be weighted in every patient with LF/LG AS.
