Objective. The aim of this work was to develop a fast and robust (semi) automatic
segmentation technique of the aortic valve area (AVA) MDCT datasets. Methods. The …

Accurate determination of severity of aortic valve stenosis (AS) by aortic valve area (AVA) is
essential for choosing the best treatment strategy. We compared AVA quantified by 4 …

Background Current guidelines place emphasis on the determination of aortic valve area
(AVA) for defining an appropriate treatment strategy. Invasive and non-invasive modalities …

Background: Among individuals who have a stenotic aortic valve, a precise assessment of
aortic valve area is essential for clinical judgment. So far, no studies have been conducted to …

Background: Transthoracic echocardiography (TTE) is routinely used to calculate aortic
valve area (AVA) by continuity equation (CE). However, accurate measurement of the left …

Background Transthoracic echocardiography (TTE) remains the first line-modality for
grading aortic stenosis (AS). Cardiac computed tomography (CT) has superior spatial …

Degenerative aortic valve stenosis (AS) has an incidence of 2–7% in the Western European
and North American populations over 65 years of age. The aim of this study was to perform a …

Aims The aims of this study were to (i) investigate aortic annulus dynamics using two-
dimensional (2D) speckle tracking echocardiography,(ii) determine optimal 2D short-axis …

We compared the measurements of the aortic valve area (AVA) using dual-source computed
tomography (DSCT) in patients with mid to severe aortic stenosis to measurements using …

Purpose: To prospectively compare the accuracy of multidetector computed tomographic
(CT) measurements of the aortic valve area (AVA) with transesophageal echocardiography …
