Background: Aortic valve stenosis is the most common type of valve lesion in Europe and
North America. Patient treatment is based on disease severity, which is classified by …

OBJECTIVE: We sought to determine the comparability of multislice computed tomography
(MSCT) and magnetic resonance imaging (MRI) for measuring the aortic valve orifice area …

Background Aortic valve area (AVA) estimation in patients with aortic stenosis may be
obtained using several methods. This study was undertaken to verify the cardiovascular …

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 …

Objectives. For evaluation of aortic valve area (AVA), transthoracic echocardiography (TTE)
is the method of choice. Cardiac magnetic resonance (CMR) at 1.5-Tesla is an alternative …

Background Magnetic resonance (MR) imaging and echocardiography both allow
assessment of aortic valve stenosis. In MR the aortic valve area (AvA) is measured using …

Background. Doppler-derived calculation of aortic valve area (AVA) using the continuity
equation can be difficult at times, eg due to poor acoustic windows, heavy calcification of the …

Background Transthoracic echocardiography (TTE) is the diagnostic routine standard for
assessing aortic stenosis (AS). However, its inaccuracies in determining stroke volume (SV) …

Continuous technical advances in cardiac computed tomography (CT) have created a
variety of new applications in the field of cardiac imaging. Through improvements in …

Background: Cardiac magnetic resonance tomography (CMR) is a new imaging technique
capable of imaging the aortic valve with high resolution. We assessed the aortic valve area …
