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, ...
Peak pressure gradient, aortic annulus size, degree of AI, left ventricular internal dimensions, and left ventricular mass were significantly reduced (p < 0.05) in the AS group. Mean fractional shortening was within normal limits pre- and postoperatively for both groups. Conclusions. Regression of...

There was no significant increase in aortic insufficiency.In selected patients undergoing ascending aortic aneurysm repair who have normal aortic leaflets but secondary aortic regurgitation, the native valve can be spared through this novel operation. The aortic annulus size is reduced significantly, ...
Body surface area is the main physiological factor determining the magnitude of stroke volume and cardiac output in a normal subject. Given that a small body size is associated with a lower transvalvular flow rate, it may lead to a discordant small AVA and a low-gradient situation. Indeed, ...

(31)]. But it allows for placement of a larger valve, since a size 19 prosthetic valve in a 19 mm aortic annulus for instance, has a much smaller inner diameter and will further narrow an already small LVOT. The Yang technique allows for supra-annular placement of a larger valve, where...
mild regurgitations can undergo aortic valve regurgitation suspension, thereby avoiding postoperative anticoagulation and related complications. Therefore, the surgical indication for aortic valve junction suspension must be limited to the absence of significant dilation of the aortic annulus and the normal mo...
The integrity of all components of theaortic root, composed of the VAJ, SOV, STJ, and aortic leaflets is essential for normalAVfunction. The STJ and VAJ act as a stent onto which the leaflets attach and is referred to as the “functional aortic annulus.”27Because the aortic leaflets are...
