Abstract:
Two cases of coronary angioplasty of very tight stenoses are reported in which, after failure of conventional low-profile catheters, a balloon-tipped guidewire was used to predilate the lesion, with subsequent advancement of a larger balloon catheter over the wire itself to complete the dilatation. It is suggested that this balloon-tipped guidewire can be helpful for safe predilatation of very tight coronary stenoses with no need for complex catheter exchanges.
