In-hospital COVID-19 infection echocardiographic analysis: a Brazilian, tertiary single-centre experience

Cardiovascular Ultrasound, 2021
Background Information is lacking concerning in-hospital echocardiography analysis of COVID-19 infection in Brazil. We evaluated echocardiographic parameters to predict a composite endpoint of mortality, pulmonary thromboembolism or acute renal failure ...

Echocardiography [PDF]

Circulation, 1972
We have discussed the evolution of selected areas of echocardiography in an attempt to illustrate the capabilities and limitations of this method of study. As information has accumulated, some concepts of the specificity of certain echocardiographic patterns have had to be revised.

Three-dimensional transthoracic echocardiographic evaluation of tricuspid regurgitation severity using proximal isovelocity surface area: comparison with volumetric method

Cardiovascular Ultrasound, 2020
Background The quantification of tricuspid regurgitation(TR) using three-dimensional(3D) proximal isovelocity surface area (PISA) derived effective regurgitant orifice area (EROA) is feasible in functional TR.

Genetic abnormalities in fetal congenital heart disease with aberrant right subclavian artery

Scientific Reports, 2022
Fetal aberrant right subclavian artery (ARSA) is a relatively common sonographic finding. Congenital heart disease (CHD) is the most common structural abnormality in patients with ARSA.

Value of Speckle Tracking Echocardiography Combined with Stress Echocardiography in Predicting Surgical Outcome of Severe Aortic Regurgitation with Markedly Reduced Left Ventricular Function

Reviews in Cardiovascular Medicine, 2023
Background: Predicting outcomes of surgical aortic valve replacement (AVR) in patients with chronic severe aortic regurgitation (AR) and markedly reduced left ventricular (LV) function remains a challenge.

Assessment of left ventricular diastolic function after Transcatheter aortic valve implantation in aortic stenosis patients by echocardiographic according to different guidelines

Cardiovascular Ultrasound, 2020
Background To evaluate the detailed dynamic change of left ventricular diastolic function (LVDF) by echocardiography in aortic stenosis (AS) patients receiving transcatheter aortic valve implantation (TAVI) and compare LVDF classification according to ...

Stress Echocardiography [PDF]

Heart, 2003
Stress echocardiography may be performed with exercise and nonexercise stressors, although the use of echo contrast agents makes insertion of an intravenous line important for both techniques. The selection of either stress protocol should be tailored to each patient, and in the opinion of this author, an effective stress echo laboratory should offer ...

The impact of different geometric assumption of mitral annulus on the assessment of mitral regurgitation volume by Doppler method

Cardiovascular Ultrasound, 2020
Background Mitral regurgitation volume (MRvol) by quantitative pulsed Doppler (QPD) method previously recommended suffers from geometric assumption error because of circular geometric assumption of mitral annulus (MA).

Ultrasound‐targeted cationic microbubbles combined with the NFκB binding motif increase SDF‐1α gene transfection: A protective role in hearts after myocardial infarction

Kaohsiung Journal of Medical Sciences, 2022
Treatment of myocardial infarction (MI) remains a major challenge. The chemokine family plays an important role in cardiac injury, repair, and remodeling following MI, while stromal cell‐derived factor‐1 alpha (SDF‐1α) is the most promising therapeutic ...
