EuroPCR 2017: Boston Scientific's Lotus TAVR Beats Medtronic's CoreValve In REPRISE III, But Pacemaker Issue Remains

Boston Scientific's repositionable, mechanically expanded Lotus transcatheter aortic valve performed better than Medtronic's CoreValve for the primary composite effectiveness endpoint in the REPRISE III trial, according to results presented at the EuroPCR meeting in Paris. But the Lotus patients in the trial were more likely to need a pacemaker than the CoreValve patients, a risk that investigators believe can be mitigated with better operator technique.
