The procedure was performed via transfemoral route using a balloon expandable (n=61) or a self expandable (n=57) valve. Pre-intervention non enhanced, ECG-gated, multislice CT-scan was done in all patients. Aortic valve calcifications were evaluated using the Agatston calcium score (CS). ...
X-ray or CT scan: Through making single or multiple images of the heart and heart valves, doctors can make a diagnosis based on the enlargement of the heart, the aorta and the calcium build up in the heart valves. Other Diagnoses: Other diagnosis methods doctors could use to support their...
An 82-year-old female with symptomatic severe aortic stenosis was scheduled for a transcatheter aortic valve implantation (TAVI). A dedicated TAVI computed tomography (CT) scan demonstrated an aortic annular area of 362 mm2, perimeter of 69 mm and average diameter of 21.5 mm (Figure 1A)...
Methods:52 patients who were scheduled for TAVI underwent an ECG-gated multislice CT scan of the aortic valve plane in addition to echocardiographic measurements. Parameters based on the CT scans were then assessed with a standar...

The CT scan will be necessary for a patient being considered for transcatheter aortic valve replacement (TAVR). Carotid duplex scanning to rule out significant carotid stenosis and a peripheral pulse exam to complete the vascular workup are routine. Furthermore, a patient about to receive ...
Figure 5 – Contrast CT scan demonstrating a 7cm thoracic aortic aneurysm (black arrow) that has ruptured; the white arrow demonstrates blood in the thorax Key Points Most cases of thoracic aneurysm are associated with connective tissue disorders or bicuspid aortic valve ...
If you're at higher risk of developing an aortic aneurysm because of a genetic condition, a family history, or a heart valve defect, it makes sense to get a screening test. You can also ask your doctor to check your aorta if you're having a chest or abdominal scan for some other rea...
There are several circumstances that should be considered prior to VAD implantation, including significant valvular disease (severe aortic or mitral valve incompetence or stenosis), aortic aneurysms and dissections, and congenital heart disease. Surgical intervention for these disorders may be required prio...
In transcatheter aortic valve implantation (TAVI), final device position may be affected by device interaction with the whole aortic landing zone (LZ) extending to ascending aorta. We investigated the impact of aortic LZ curvature and angulation on TAVI
