Dual-Source CT Angiography for Detection and Quantification of In-Stent Restenosis in the Left Main Coronary Artery: Comparison with Intracoronary Ultrasound and Coronary Angiography

Popis výsledku v původním jazyce

Objectives. The aim of this study was to evaluate the diagnostic accuracy of dual-source computed tomography coronary angiography (CTCA) compared to coronary angiography (CAG) and intravascular ultrasound (IVUS) for detection and quantification of in-stent restenosis after left main (LM) coronary artery stenting. Materials and Methods. Fifty-one patients with percutaneous coronary intervention of the LM were prospectively evaluated. Thirty-four of them underwent 56 complete follow-up examinations (CTCA,CAG, and IVUS as gold standard examination) that focused on detection and quantification of restenosis. Results. Sensitivity, specificity, and positive and negative predictive values were 100%, 94%, 50%, and 100% for CAG, respectively, and 100%, 74%, 18%, and 100% for CTCA, respectively. There was a correlation between the minimal luminal areas (MLA) measured by CTCA and IVUS (r = 0.63; P<.01). A Bland-Alt-man analysis showed that the MLA measured by CTCA was underestimated (mean differ
