Abstract:
BACKGROUND: 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. MATERIALS AND METHODS: Intravascular ultrasound (IVUS) guided single-coronary stenting was successfully performed in 384 consecutive patients with 407 native coronary lesions. Six-month follow-up angiogram was performed in 315 patients (82.0%) with 334 lesions (82.1%). Minor plaque prolapsed within stent occurred in 75 of 334 lesions (22.5%). Results were evaluated using angiographic and IVUS methodology. RESULTS: The development of minor plaque prolapse was significantly associated with infarct-related artery (p=.000) and smaller pre-intervention minimal lumen diameter (p=.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=.806). CONCLUSION: Minor plaque prolapsed within stents might not be associated with late angiographic in-stent restenosis.
