What was done
This narrative review examines the historical evolution, current diagnostic capabilities, and recent technological trends of coronary computed tomography angiography (CCTA) in diagnosing coronary in-stent restenosis following percutaneous coronary intervention.
What was found
The abstract reports no numerical data. It notes qualitatively that while blooming and motion artifacts historically limited CCTA's ability to clearly visualize stent lumens and often required conventional invasive angiography, recent technical advancements have improved sensitivity and specificity, with studies consistently reporting high negative predictive value.
Why it matters
Highlights the growing non-invasive role of CCTA in ruling out coronary in-stent restenosis, potentially reducing unnecessary invasive conventional angiography procedures.
Limits
The record is a narrative review without original clinical data, pooled meta-analytic metrics, or systematic search details in the abstract. No quantitative figures for diagnostic accuracy, scanner platforms, or stent types are provided.
Cited by
- context CT coronary angiography causes blooming artifact around preexisting coronary stents, preventing clear visualization inside the stent.
