The purpose of this study is to analyze the geometrical characteristics of aortic root and left
ventricular (LV) function in aortic stenosis (AS) using 256-slice coronary-computed …

With advent of transcatheter aortic valve implantation, using multislice computed
tomography (MSCT) to provide detailed data about aortic root has become more crucial. We …

Severe aortic stenosis (AS) is defined as an aortic valve area (AVA)# 1.0 cm2, a mean
gradient $40 mm Hg, and/or peak velocity $4 m/s (1). These measurements are most often …

Cardiac pulsatility and aortic compliance may result in aortic area and diameter changes
throughout the cardiac cycle in the entire aorta. Until this moment these dynamic changes …

The purpose of this study was to assess by multislice computed tomography (MSCT)
imaging geometry of the ascending aorta, the aortic root, the aortic annulus and the left …

Purpose: To quantitatively measure the aortic root anatomy and left ventricular function in
the cardiac cycle in healthy and hypertensive subjects. Materials and methods: One hundred …

To evaluate the inter-individual variance and the variability of the aortic root dimensions
during the cardiac cycle by computed tomography (CT) in patients with severe aortic …

Aims Understanding normal asymmetry in the aortic root could aid in the development of
new surgical repair techniques or devices with improved haemodynamic performance. The …

Detailed knowledge of aortic root geometry is a prerequisite to anticipate complications of
transcatheter aortic valve (TAV) implantation. We determined coronary ostial locations and …

Background Transthoracic echocardiography (TTE), multidetector computed tomography
(MDCT), and magnetic resonance imaging (MRI) have been widely used to monitor aortic …
