CT in Calcified Coronary Arteries With Photon Counting Detector

NCT05551351 · Status: TERMINATED · Type: OBSERVATIONAL · Enrollment: 29

No results posted yet for this study

Summary

Coronary CT angiography is challenging in patients with more than mildly calcified coronary vessels, because of calcium artefacts that prevents evaluation of the lumen. The purpose of the CCT-PCD-1-study is to evaluate the diagnostic accuracy and image quality in coronary CT angiography using a commercially available CT system equipped with a photon counting detector technology.

Patients referred for cardiac CT and conventional coronary angiography as part of routine preoperative evaluation before Transcatheter Aortic Valve Implantation (TAVI) will be asked for inclusion in the study. This group of patients has generally a coronary artery calcium burden and perform cardiac CT and coronary angiography as part of routine care.

The diagnostic accuracy concerning significant coronary artery stenosis on the preoperative CT will be evaluated with the conventional coronary angiography as reference. Also, CT examination image quality will be evaluated.
