Aortic annular rupture is a potentially fatal complication after transcatheter aortic valve implantation with high mortality. Although it is quite rare and difficult to identify the mechanisms and predictors, prosthesis oversizing and massive calcification of the aortic annulus are thought to be a potential risk of this complication. A case presented here is an aortic annular rupture after transcatheter aortic valve implantation. Although the valve was not oversized, there were 2 severe calcifications of aortic annulus at nearby areas like “twin icicles,” thought to be a trigger of this potentially fatal complication.
