Physiological maps were created, whereby the post-intervention iFR (post-iFR) was predicted as iFRpred. The iFR gap was defined if the difference between the iFRpred and post-iFR was\u2009\u2265\u20090.3. The lesion morphology changed from that during the physiological assessment to that during the angiographic assessment in 26 lesions (37.1%). In particular, 22.6% of angiographic tandem lesions changed to physiological focal lesions. The mean pre-intervention iFR, post-iFR, and iFRpred were 0.73\u2009\u00b1\u20090.17, 0.90\u2009\u00b1\u20090.06, and 0.93\u2009\u00b1\u20090.05, respectively. The mean difference between the iFRpred and post-iFR was 0.029\u2009\u00b1\u20090.099, with 95% limits of agreement of -0.070\u20130.128. iFR gaps occurred in 28 patients (40%). Notably, a new iFR gradient causing a\u2009\u2265\u20090.03 iFR drop after stenting occurred in 11 (15.7%) cases. The study patients were divided into two groups according to biases between post-iFR and iFRpred\u2009&lt;\u20090.03 (good concordance group) or\u2009\u2265\u20090.03 (poor concordance group). The pre-intervention heart rate was the only independent predictor of poor concordance (odds ratio, 0.936; 95% confidence interval 0.883\u20130.992; <jats:italic>p<\/jats:italic>\u2009=\u20090.027). Physiological maps under resting conditions may contribute to a reduction in unnecessary stent placements without missing lesions requiring treatment. However, the predictive accuracy of post-iFR performance in the present study was slightly lower than that in the previous reports.<\/jats:p>","DOI":"10.1007\/s12928-020-00668-0","type":"journal-article","created":{"date-parts":[[2020,6,7]],"date-time":"2020-06-07T07:02:25Z","timestamp":1591513345000},"page":"208-218","update-policy":"https:\/\/doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":20,"title":["Utility of angiography\u2013physiology coregistration maps during percutaneous coronary intervention in clinical practice"],"prefix":"10.1007","volume":"36","author":[{"given":"Akiko","family":"Matsuo","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Takeru","family":"Kasahara","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Makoto","family":"Ariyoshi","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Daisuke","family":"Irie","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Koji","family":"Isodono","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yoshinori","family":"Tsubakimoto","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Tomohiko","family":"Sakatani","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Keiji","family":"Inoue","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hiroshi","family":"Fujita","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"297","published-online":{"date-parts":[[2020,6,7]]},"reference":[{"key":"668_CR1","first-page":"e574","volume":"124","author":"GN Levine","year":"2011","unstructured":"Levine GN, Bates ER, Blankenship JC, Bailey SR, Bittl JA, Cercek B, et al. 2011 ACCF\/AHA\/SCAI Guideline for percutaneous coronary intervention.
