Abstract
We report fluttering bioprosthetic leaflet, assessed by intravascular ultrasound, during valve-in-valve transcatheter aortic valve replacement, successfully treated by using chimney stenting. Valve-in-valve transcatheter aortic valve replacement is still a challenging situation, particularly in cases with a shallow distance between leaflet and coronary ostium; a multimodality imaging approach helped manage this situation. (Level of Difficulty: Intermediate.).
