title: Preventive left main and right coronary artery stenting to avoid coronary ostia occlusion in high-risk stentless valve-in-valve transcatheter aortic valve implantation.
abstract: Transcatheter aortic valve implantation is becoming an attractive and promising alternative to redo surgery for aortic bioprosthetic valves degeneration, especially in high-risk patients. However, valve-in-valve transcatheter aortic valve implantation itself carries some procedural risks and potential challenges that interventionists must be aware of. An accurate preprocedural planning is fundamental for the prevention of potentially fatal complications. This case describes a novel strategy of simultaneous right and left coronary artery stenting preventing bilateral coronary obstruction in a patient with a stentless surgical aortic valve and extremely low origin of the 2 coronary arteries.
