Evaluation of coronary stents using multidetector CT

BackgroundRecurrent ischemic symptoms after coronary stenting require imaging assessment to rule-out in-stent restenosis or occlusion.AimTo evaluate role of multi-detector computed tomography in assessment of coronary artery stents.Patients and methodsTwenty-four patients were referred to assess coronary stents.All were subjected to history taking, clinical examination and computed tomography angiography of coronary arteries using 320-row multi-detector computed tomography.ResultsThere were totally sixty-three coronary artery stents. Only six stents were non-interpretable. Where forty-eight patent, while nine stents showed in-stent restenosis of significant degree (⩾50%), most stents 3.0 mm diameter.ConclusionMulti-detector computed tomography is considered convenient and reliably non-invasive imaging modality for assessment of suspected coronary stents with large diameter.
