The direct relationship between minor plaque prolapsed within stents and late in‐stent restenosis is unknown. Therefore, we evaluated the impact of minor plaque prolapse on late angiographic in‐stent restenosis. Intravascular ultrasonography (IVUS)–guided single‐coronary stenting was successfully performed on 384 consecutive patients with 407 native coronary lesions. Six‐month follow‐up angiographic evaluation was performed on 315 patients (82.0%) with 334 lesions (82.1%). Minor plaque prolapsed within the stent was found in 75 of 334 lesions (22.5%). Results were evaluated using angiographic and IVUS methods. The development of minor plaque prolapse was significantly associated with infarct‐related artery ( P = 0.000) and small pre‐intervention minimal lumen diameter ( P = 0.001). The overall angiographic restenosis rate was 23.1% (77/334)—21.3% (16/75) in the lesions with plaque prolapse vs. 23.6% (61/259) in the lesions without plaque prolapse ( P = 0.806). In conclusion, minor plaque prolapsed within stents might not be associated with late angiographic in‐stent restenosis. Cathet. Cardiovasc. Intervent. 51:22–26, 2000. © 2000 Wiley‐Liss, Inc.
