Key result
Emergent chimney stenting successfully rescues acute left main occlusion after valve-in-valve TAVI.
Why the study?
Coronary occlusion is a potential fatal complication during valve-in-valve transcatheter aortic valve implantation that requires effective management strategies.
Can emergent percutaneous coronary intervention (chimney stent) resolve left main occlusion following valve-in-valve TAVI?

Can emergent percutaneous coronary intervention (chimney stent) resolve left main occlusion following valve-in-valve TAVI?
Emergent chimney stenting is a feasible bailout strategy for acute left main coronary occlusion complicating valve-in-valve TAVI.
May support chimney stenting as bailout for this rare TAVI complication; hypothesis-generating and requires prospective validation.
Implantation of transcatheter valves inside degenerated surgical bioprosthesis is nowadays a very good alternative to redo a new cardiac surgery especially in high risk patients.Although procedural success is achieved in most of the patients, these procedures are associated with few potential risks such as coronary occlusion.It is very important to perform an exhaustive study prior to the valve implantation so as to prevent possible fatal complications.In this paper we show that in case of coronary occlusion one possibility to solve it is emergent percutaneous coronary intervention.

González et al. (2018) conducted a case report in Symptomatic bioprosthesis degeneration / Left main occlusion (n=1). Emergent percutaneous coronary intervention with chimney stent was evaluated on Resolution of coronary occlusion and patient survival. Emergent percutaneous coronary intervention using a chimney stent successfully resolved a life-threatening left main coronary occlusion following a valve-in-valve TAVI procedure.
