Diagnostic accuracy of dual-source computed tomography coronary angiography in patients undergoing evaluation for transcatheter aortic valve implantation

Ziele: To prospectively investigate diagnostic accuracy for dual-source computed tomography coronary angiography (CTCA) to diagnose significant coronary artery stenosis compared with catheter coronary angiography (CCA) in patients with severe aortic stenosis undergoing assessment of aortic root anatomy for transcatheter aortic valve implantation (TAVI). Methode: One-hundred-twenty consecutive patients (64/56 female/male, mean age 79.0±10.9 years) with severe aortic stenosis (0.7±0.1 aortic valve area cm2) underwent a specific dual-source computed tomography protocol for evaluation of aortic root and coronay anat…
