At multivariable linear regression analysis transcatheter procedure, baseline aortic diameter and paravalvular leak were significantly associated with increased postoperative AA dilatation. CONCLUSIONS. Bicuspid AV patients who underwent SAVR, showed significantly less long-term AA diameter progression than ...
generally occurring at systole The maximum Reynolds number at any time during the cardiac cycle, at a single position in the ascending aorta Table 1. Definitions and time scales of haemodynamic metrics included in the genetic analyses. In both cases of Re, D is the diameter of the ...
22 Aortic size was measured in the parasternal long axis view at end diastole at 4 levels: (1) aortic annulus, (2) sinuses of Valsalva, (3) sinotubular junction, and (4) ascending aorta (2-3 cm above the sinotubular junction at the maximal visualized diameter). Aortic measurements, ...
AAo: ascending aorta; CMR: cardiovascular magnetic resonance; LV: left ventricular; Sens: sensitivity; Spec: specificity. Intra- and interobserver variability in cardiovascular magnetic resonance A sample of 18 randomly chosen cases was reanalyzed. Intraobserver variability of the AAo diameter ...

Inflatable balloon 27 may be positioned in the ascending aorta by utilizing ultrasound techniques or fluoroscopic imagery. FIG. 2 illustrates the use of a catheter system interface 31 where an ultrasonic image of scanned tissue is presented on a television monitor. A transopical echo device 32 ...
However, and despite its importance, methods to measure the stiffness of the ascending aorta are limited. Objective: To introduce a method for calculating local PWV in the human ascending aorta using non-invasive ultrasound measurements of its diameter (D) and flow velocity (U). Approach: Ten ...
The 2D-TTE diameter using the L-L convention correlated best with the non-coronary-to-right-coronary cusp determined by both MDCT and MRI. Aortic root and ascending aorta diameters measured by 2D-TTE using the leading-to-leading edge convention showed accurate and reproducible values compared ...
Discriminatory Value of the Ascending Aorta Diameter in Suspected Acute Type A Aortic Dissectiondoi:10.1111/acem.13547The objective was to determine if ascending aorta (AscAo) diameters measured by noncontrast computed tomography (CT) allow for meaningful discrimination between patients with and without...
Systemic arterial compliance, arterial stiffness and corrected CAAS (β = 0.23, P = .02) were independently associated with AAo diameter. Conclusions TOF patients have a larger and stiffer AAo compared to controls. CAAS derived from 2D‐STE allows a routine noninvasive method for assessing AAo ...
