Impact of atrial fibrillation in clinical outcomes of low gradient aortic stenosis

European Heart Journal, 2022
Aortic stenosis (AS) is the most common significant valvular heart disease in developed countries. A significant portion of the AS populations have low-gradient AS (LGAS), defined as aortic valve area ≤1.0 cm2 and a trans-aortic mean systolic ...

The normal ranges of cardiovascular parameters measured using the ultrasonic cardiac output monitor [PDF]

, 2017
The ultrasonic cardiac output monitor (USCOM) is a noninvasive transcutaneous continuous wave Doppler method for assessing hemodynamics. There are no published reference ranges for normal values in adults (aged 18– 60 years) for this device.

Subthreshold Aortic Valve Calcium Scores in Severe Aortic Stenosis and Transthyretin Cardiac Amyloidosis

JACC: Case Reports, 2020
We have clinically observed that some patients with transthyretin cardiac amyloidosis and severe aortic stenosis may have lesser degrees of calcification than one might expect.

Quantification of Local Hemodynamic Alterations Caused by Virtual Implantation of Three Commercially Available Stents for the Treatment of Aortic Coarctation [PDF]

, 2013
Patients with coarctation of the aorta (CoA) are prone to morbidity including atherosclerotic plaque that has been shown to correlate with altered wall shear stress (WSS) in the descending thoracic aorta (dAo).

Aortic Valve Calcium Score by Computed Tomography as an Adjunct to Echocardiographic Assessment—A Review of Clinical Utility and Applications

Journal of Imaging, 2023
Aortic valve stenosis (AS) is increasing in prevalence due to the aging population, and severe AS is associated with significant morbidity and mortality.

Clinical Value of Stress Transaortic Flow Rate During Dobutamine Echocardiography in Reduced Left Ventricular Ejection Fraction, Low-Gradient Aortic Stenosis: A Multicenter Study

Circulation Cardiovascular Imaging, 2021
Supplemental Digital Content is available in the text. Background: Low rest transaortic flow rate (FR) has been shown previously to predict mortality in low-gradient aortic stenosis.

Echocardiographic evaluation of velocity ratio, velocity time integral ratio, and pulmonary valve area in dogs with pulmonary valve stenosis. [PDF]

, 2018
BackgroundVelocity ratio, velocity time integral (VTI) ratio, and pulmonary valve area indexed to body surface area (iPVA) are methods of assessment of pulmonary valve stenosis (PS) severity that are less dependent on blood flow. Studies evaluating these

Transfemoral aortic valve replacement in a nonagenarian with aortic stenosis and cardiac amyloidosis: case report

Journal of Cardiothoracic Surgery, 2022
Background Cardiac amyloidosis (CA) is diagnosed with increasing frequency in the elderly population with severe aortic stenosis (AS), especially with the low-flow, low- gradient phenotype. Prognosis is poor with no treatment.

Systolic ejection murmurs and the left ventricular outflow tract in boxer dogs [PDF]

, 2007
Turbulence of various genesis in the left ventricular outflow tract (LVOT) causes systolic ejection murmurs. The prevalence of murmurs in adult boxer dogs is 50-80%, the majority of which are of low intensity.
