Validation of the severity index by cardiac catheterization and Doppler echocardiography in patients with aortic sclerosis and stenosis
The severity index is a new echocardiographic measure that is thought to be an accurate indicator of aortic leaflet pathology in patients with AS. However, it has not been validated against cardiac catheterization or Doppler echocardiographic measures of AS severity nor has it been applied to patients with aortic sclerosis. The purposes of this study were to compare the severity index to invasi...
متن کاملNon-invasive estimation of cardiac wall stress by using tissue doppler-echocardiography ultrasound images: People with coronary artery stenosis
In this study, a method for non-invasive estimation of stress on the heart wall in the diastole phase is presented using ultrasound echocardiography and tissue Doppler imaging. The aim of this study was to evaluate the stress on the heart wall as a pre-diagnosis to identify people with coronary artery stenosis. 29 patients with stenosis of more than 70%, 30 patients with stenosis of 50 to 7...
متن کاملPrognostic Value of Aortic Valve Area by Doppler Echocardiography in Patients With Severe Asymptomatic Aortic Stenosis
BACKGROUND The aim of this study was to evaluate the relationship between aortic valve area (AVA) obtained by Doppler echocardiography and outcome in patients with severe asymptomatic aortic stenosis and to define a specific threshold of AVA for identifying asymptomatic patients at very high risk based on their clinical outcome. METHODS AND RESULTS We included 199 patients with asymptomatic s...
متن کاملComparison of Doppler echocardiographic methods with heart catheterisation in assessing aortic valve area in 100 patients with aortic stenosis.
OBJECTIVE To examine the practicability and accuracy of Doppler echocardiographic methods in determining aortic valve area. METHODS Aortic valve areas determined by three methods using Doppler echocardiography (applying the continuity equation and the modified Gorlin formula using data from Doppler echocardiography and right heart catheterisation) were compared with values obtained by heart c...
متن کاملEchocardiography in Severe Aortic Stenosis
Aortic stenosis (AS) is the most frequent valvular heart disease in west developed and developing countries, with prevalence between 0.02% in adults under 44 years and 3-9% in elderly over 80 years. Patients with this disease may remain asymptomatic for years, particularly in elderly with naturally limited exercise. If the patients remain untreated after they become symptomatic, the mortality a...
