Abstract
The treatment of coronary artery stenosis has progressively shifted over the past decades, from surgical (coronary artery bypass graft) to percutaneous (percutaneous coronary intervention and stenting). The recent introduction of drug-eluting stents further reduced the occurrence of in-stent restenosis. However, a non-negligible number of patients need imaging/functional tests when symptoms recur. Multi-slice CT coronary angiography (CT-CA) is a clinical reality for the evaluation of coronary artery stenosis but is still being evaluated for the follow-up after coronary stent implantation. Several factors may impair proper depiction of in-stent lumen even with the most recent CT equipment. In highly selected populations, CT-CA may play a clinical role, even though the performance requirements both from the technical standpoint (ie, CT scanner) and from the training (ie, operators’ experience) are still very demanding. In the meantime, CT technology should improve toward higher contrast, spatial, and temporal resolution in order to achieve the imaging performance needed for clinical implementation.
