valve implantation (TAVI)
1)
Because of the relatively large diameter of the delivery
sheaths (≥18F= 6mm), appropriate vascular access is critical.
(at least 1/3 of patients with critical aortic stenosis had unfavorable
iliacal Arteiies with the majority of those patients having minimal luminal
diameters of 8 mm. In such patient alternative access
approaches may include surgical sidegraft on the iliac
arteries, transaxillary, or transapical access.)
2)
Measurement of the aortic sinus diameter, sinotubular
junction, ascending and descending aorta are performed
using centerline reconstructions. The presence of significant
aneurysmal dilatation is considered a contraindication for
TAVI. The extent of atherosclerotic plaque (48) is likely
associated with complications including stroke
