CT Abdomen and Pelvis Without IV Contrast CT abdomen and pelvis without IV contrast cannot assess lumen size and patency, but mural calcifications can be assessed. In a comparative study of 103 of 588 patients undergoing both noncontrast CT and angiography, with 17 sheath-related complications, Okuyama et al [23] showed there was no difference between noncontrast CT and angiography: area under the curve 0.79 (95% CI, 0.70-0.86) versus area under the curve 0.73 (95% CI, 0.63-0.81) in predicting sheath-related complications. CT Chest, Abdomen, and Pelvis With IV Contrast There is no relevant literature to support the use of CT chest, abdomen, and pelvis with IV contrast as the initial imaging modality for the evaluation of vascular access before a TAVR procedure. CT Chest, Abdomen, and Pelvis Without and With IV Contrast There is no relevant literature to support the use of CT chest, abdomen, and pelvis without and with IV contrast as the initial imaging modality for the evaluation of vascular access before a TAVR procedure. Aortic calcification can: however, be assessed on CT chest, abdomen, and pelvis without and with IV contrast. Harbaoui et al [38] evaluated 189 patients undergoing TAVR for total aortic calcifications, ascending aortic calcification, descending Transcatheter Aortic Valve Replacement aorta calcifications, and abdominal aorta calcifications. In their study, total aortic calcification (tertile 3 versus tertile 1) was significantly and strongly associated with cardiac mortality (HR: 16.74; 95% CI, 2.21-127.05; P = . 006) and all-cause mortality (HR: 2.39; 95% CI, 1.18-4.84; P = . 015). Each aortic calcified segment was associated with cardiac mortality, whereas only ascending aortic calcification (tertile 3 versus tertile 1) appeared predictive of heart failure (HR: 2.29; 95% CI, 1.12-4.66; P = . 023).
