CT Chest, Abdomen, and Pelvis Without IV Contrast There is no relevant literature to support the use of CT chest, abdomen, and pelvis without IV contrast as the initial imaging modality for the evaluation of vascular access before a TAVR procedure. CT chest, abdomen, and pelvis without IV contrast cannot assess lumen size and patency, but mural calcifications can be assessed. CT Chest With IV Contrast There is no relevant literature to support the use of CT chest with IV contrast as the initial imaging modality for the evaluation of vascular access before a TAVR procedure. CT Chest Without and With IV Contrast There is no relevant literature to support the use of CT chest without and with IV contrast as the initial imaging modality for the evaluation of vascular access before a TAVR procedure. CT Chest Without IV Contrast There is no relevant literature to support the use of CT chest without IV contrast as the initial imaging modality for the evaluation of vascular access before a TAVR procedure. CT chest without IV contrast cannot assess lumen size and patency, but mural calcifications can be assessed. Additionally, circumferential aortic calcifications (porcelain aorta) can be detected, which may complicate the device delivery [56]. CT Heart Function and Morphology With IV Contrast There is no relevant literature to support the use of CT heart function and morphology with IV contrast as the initial imaging modality for the evaluation of vascular access before a TAVR procedure. Preprocedural CT heart function and morphology with IV contrast can help in identifying left ventricular apex and assess myocardial thickness and left ventricular orientation and in guiding planned mini-thoracotomy. CTA Abdomen and Pelvis With IV Contrast CTA imaging can assess luminal size, patency, vessel tortuosity, and the extent of mural calcifications.
