Poor mobility predicts worse survival among patients undergoing TAVI, both in the shorter and longer terms. Our data suggest that mobility impairment, of either neurological or musculoskeletal etiology, is an appropriate screening measure when considering patients for TAVI.
This analysis represents the largest published series on use of the LOTUS valve. Outcomes using this valve are excellent. In-hospital mortality is very low. Complication rates are low, and the LOTUS valve improves on first-generation valves, particularly with regard to residual aortic regurgitation.
Following implantation of the repositionable LOTUS valve, 55% of patients developed LBBB and 32% of patients required a pacemaker during their index hospital admission. Patients with pre-procedural conduction disturbance and non-calcified aortic valves were more likely to need pacing. No other anatomic features were identified with increased pacing requirement with the LOTUS device.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
