Abstract
The therapeutic strategy for percutaneous coronary intervention (PCI) of a tapered
lesion is still being developed. Herein, we describe a 67-year-old man with stable
angina who underwent elective PCI of a tapered lesion. The coronary angiogram showed
diffuse, severe stenosis in the tapered left anterior descending artery. A third-generation
sirolimus-eluting stent (2.5 × 24-mm Ultimaster, Terumo, Tokyo, Japan) was deployed,
and the distal side was selected as the reference. Postdilatation with a balloon diameter
2.0 mm larger than the stent was needed because of the tapered lesion. We performed
postdilatation from the distal side to the proximal side of the stent with a noncompliant
balloon (4.5 × 8-mm Powered Lacrosse2, Goodman, Aichi, Japan). The final angiogram
showed that the total stent length was 6 mm longer than the original length. Therefore,
physicians should be aware of longitudinal stent elongation of a tapered lesion during
PCI to ensure appropriate treatment.
