Key result
High pressure inflation of a Cutting Balloon achieved adequate dilation for stenting in a heavily calcified restenotic mid-LAD lesion after conventional non-compliant balloons failed and ruptured.
Why the study?
Does a Cutting Balloon improve adequate dilation for stenting in a patient with a resistant, heavily calcified restenotic lesion compared to conventional non-compliant balloons?

Does a Cutting Balloon improve adequate dilation for stenting in a patient with a resistant, heavily calcified restenotic lesion compared to conventional non-compliant balloons?
A cutting balloon can successfully predilate heavily calcified, resistant coronary lesions when conventional non-compliant balloons fail.

May facilitate stenting after non-compliant balloon failure in resistant calcified lesions; hypothesis-generating case report requiring prospective validation.
A 65-year-old man with a restenotic lesion of the mid LAD was scheduled for Wiktor stent placement. The IVUS revealed circumferential severe calcification. Two conventional, non-compliant angioplasty balloons inflated to high pressures failed to achieved sufficient dilatation and both ruptured. At this point, we selected high pressure inflation of the Cutting Balloon. The Cutting Balloon achieved adequate dilation for stenting and proved to be useful in predilating a circumferential, heavily calcified lesion.

Asakura et al. (1998) conducted a case report in Restenotic lesion of the mid LAD with circumferential severe calcification (n=1). Cutting Balloon vs. Conventional, non-compliant angioplasty balloons was evaluated on Adequate dilation for stenting. High pressure inflation of a Cutting Balloon achieved adequate dilation for stenting in a heavily calcified restenotic mid-LAD lesion after conventional non-compliant balloons failed and ruptured.
