Treatment of coronary artery disease in very small vessels is associated with an increased risk for cardiac events. The CENTURY JSV study is a prospective, multicenter, single-arm study. Seventy patients with stable and unstable coronary artery disease with a coronary lesion eligible for implantation with a 2.25\u00a0mm stent were enrolled in this study. Patients underwent clinical follow-up through 5-year after the PCI procedure. The mean age was 70.4\u2009\u00b1\u20099.2\u00a0years. The prevalence of diabetes mellitus was 37.1%, all not insulin dependent. The incidence of major adverse cardiac events, defined as cardiac death, target vessel myocardial infarction (MI), and clinically driven target lesion revascularization (CD-TLR) at 5\u00a0years was 5.7%. A non-Q wave MI was noted in 1.4% and 4.3% underwent a CD-TLR. There was no stent thrombosis during the entire follow-up period. No cardiac events were reported between 2 and 5\u00a0years. This is the first study to demonstrate safety and effectiveness for 5\u00a0years after treatment of very small coronary disease with 2.25\u00a0mm-diameter DES.<\/jats:p><jats:p>Clinical trial registration: UMIN000012928<\/jats:p>","DOI":"10.1007\/s12928-022-00890-y","type":"journal-article","created":{"date-parts":[[2022,9,2]],"date-time":"2022-09-02T03:22:25Z","timestamp":1662088945000},"page":"194-201","update-policy":"https:\/\/doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":7,"title":["Five-year clinical outcomes of a 2.25\u00a0mm sirolimus-eluting stent in Japanese patients with very small coronary artery disease: final results of the CENTURY JSV study"],"prefix":"10.1007","volume":"38","clinical-trial-number":[{"clinical-trial-number":"umin000012928","registry":"10.18810\/umin-japan"}],"author":[{"given":"Koki","family":"Shishido","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Kenji","family":"Ando","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yoshiaki","family":"Ito","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Itaru","family":"Takamisawa","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Junji","family":"Yajima","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Takeshi","family":"Kimura","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Kazushige","family":"Kadota","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Shigeru","family":"Saito","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"297","published-online":{"date-parts":[[2022,9,2]]},"reference":[{"issue":"2","key":"890_CR1","doi-asserted-by":"publisher","first-page":"e167","DOI":"10.4244\/EIJV12I2A30","volume":"12","author":"J W\u00f6hrle","year":"2016","unstructured":"W\u00f6hrle J, Markovic S, Rottbauer W, Muramatsu T, Saito S, Wijns W, et al.
