Purpose To compare the accuracy of planimetric and continuity equation measurements of
aortic valve area (AVA) by cardiac MR (cMR) to each other and against transthoracic (TTE) …

OBJECTIVE: The aims of this study were to investigate absolute assessment of aortic valve
area (AVA), before surgery for aortic stenosis, using cardiovascular magnetic resonance …

Aim To prospectively evaluate the accuracy of cardiac magnetic resonance (cMR) imaging
for the assessment of aortic valve effective orifice area (EOA) by continuity equation and …

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 …

Objective: To evaluate whether direct planimetry of aortic valve area (AVA) by cardiac
magnetic resonance (CMR) imaging is a reliable tool for determining the severity of aortic …

Background: The aim of the study was to determine whether noninvasive planimetry of aortic
valve area (AVA) by magnetic resonance imaging (MRI) is feasible and reliable in patients …

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 …

Hakki's formula (simplified Gorlin formula) can be used during cardiac catheterization to
calculate the stenosed cardiac valve areas and can also be adapted to magnetic resonance …

Background: Aortic stenosis (AS) is the most common valvular heart disease resulting in
surgical intervention. Transthoracic echocardiography (TTE) utilizing the continuity equation …

Objectives: The purpose of the present study was to evaluate whether magnetic resonance
(MR) planimetry of the aortic valve area (AVA) may prove to be a reliable, non-invasive …
