For the first time, we employed novel approach, namely second valve dragging, to address mispositioned self-expanding valve. This implementation of novel and successful interventional treatment led to the rapid relief of coronary obstruction.DiscussionThis innovative approach offers a promising avenue for further management of these patients in critical conditions.
