Why the study?
Does the presence, type, or severity of sleep disordered breathing influence mortality after TAVI in patients with severe aortic stenosis?
Does the presence, type, or severity of sleep disordered breathing influence mortality after TAVI in patients with severe aortic stenosis?
Sleep disordered breathing is highly prevalent in patients with severe aortic stenosis undergoing TAVI but does not appear to impact post-procedural mortality.
SDB should not yet alter TAVI risk assessment or management; leaves open whether screening or treatment affects outcomes in severe aortic stenosis.
SDB, with a preponderance of CSA, was found to be highly prevalent in patients with high-grade AS scheduled for TAVI. SDB prevalence was independent of left ventricular function. Mortality after TAVI was not influenced by the type or severity of SDB.
