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.
