In a head-to-head comparison, the LANDMARK trial looked at valves from the new balloon-expandable Myval® by Merril Life Sciences and compared them with the balloon-expandable Sapien® from Edwards Lifesciences and the self-expanding Evolut® valve from Medtronic.
The new Myval platform offers multiple valves sized at 1.5 mm intervals, while the other two have valves that are generally sized at intervals of 3.0 mm.
The platform with intermediate sizes provided a nonsignificant numerical advantage in both safety and efficacy over its rivals.
