PURPOSE: To assess the potential ability of two-dimensional speckle tracking analysis (STE) during atrial fibrillation (AF) to identify patients with LA appendage thrombi (LAAT). METHODS: This study involved 93 patients with AF (39% female, 67.1 ± 9.5 years) who were referred for a clinical indication for transesophageal echocardiography (TEE). TEE revealed LAAT in 39 (42%) patients. We analyzed standard parameters of the left ventricle (LV) and LA in transthoracic echocardiography...

Heart failure (HF) is a threat to public health. Heterogeneities in etiology and phenotype complicate the diagnosis and management of HF. This is especially true when considering HF with preserved ejection fraction (HFpEF) which make up 50% of HF cases. Natriuretic peptides may aid in establishing a working diagnosis in patients suspected of HF, but echocardiography remains the optimal choice for diagnosing HF. Echocardiography provides important prognostic information in both HF with reduced ejection fraction (HFrEF) and HFpEF...

PURPOSE: Coronary artery tortuosity (CAT) is an anatomical condition in which epicardial coronary arteries have abnormal curves or spiral courses. Although correlated with higher rates of positive stress test, its effects on the myocardial function remain to be clearly defined. METHODS: We included in this cross-sectional study and evaluated with 2D speckle-tracking echocardiography 40 consecutive patients admitted to our hospital for selective coronary angiography which showed severe CAT without significant epicardial coronary artery stenosis, and 40 consecutive subjects matched for age, hypertension, and diabetes in whom selective coronary angiography showed neither CAT nor significant epicardial coronary artery stenosis...

It is widely known that various factors contribute to left atrial (LA) mechanical dysfunction in patients with end stage renal disease (ESRD). However, the connection between atrial dysfunction and arrhythmic events such as paroxysmal atrial fibrillation (PAF), in this group of patients, remains unclear. The purpose of our study was to evaluate prospectively the association between LA deformation indices and PAF in ESRD patients. 79 patients (41 men, mean age 57 ± 17) with ESRD and preserved left ventricular systolic function comprised the study population...

OBJECTIVES: The aim of this study was to test the hypothesis that echocardiographic strain imaging, by tracking subtle alterations in myocardial function, and cardiac magnetic resonance T1 mapping, by quantifying tissue properties, are useful and complement each other to detect acute cellular rejection in heart transplant recipients. BACKGROUND: Noninvasive alternatives to endomyocardial biopsy are highly desirable to monitor acute cellular rejection. METHODS: Surveillance endomyocardial biopsies, catheterizations, and echocardiograms performed serially according to institutional protocol since transplantation were retrospectively reviewed...

OBJECTIVES: This cross-sectional study aimed to describe the functional and structural cardiac abnormalities that occur across a spectrum of cardiac amyloidosis burden and to identify the strongest cardiac functional and structural prognostic predictors in amyloidosis using cardiac magnetic resonance (CMR) and echocardiography.

Antiphospholipid syndrome (APS) patients have high cardiovascular risk. Speckle-tracking echocardiography (STE) detects myocardial function. To evaluate the myocardial function in primary APS (PAPS) patients using two-dimensional echocardiography (2-D) obtaining values of left ventricle global longitudinal strain (GLS) by STE. Patients with PAPS, > 16 years, both genders, without signs and symptoms of heart disease were recruited and matched with healthy controls by age and gender. Demographic, clinical data, and cardiovascular risk factors were recorded...

Objective: Thoracoscopic surgical pulmonary vein isolation (sPVI) has been added to the treatment of atrial fibrillation (AF), showing excellent efficacy outcomes. However, data on right ventricular (RV) function following sPVI has never been studied. Our aim was to investigate RV function following sPVI and compare it to patients who underwent endocardial cryoballoon PVI. Methods: 25 patients underwent sPVI and were pair-matched according to age, sex, and AF type with 21 patients who underwent cryoballoon PVI...

The right atrium (RA) is the most under-evaluated heart chamber in the clinical practice. Three-dimensional (3D) speckle-tracking echocardiography (STE) merges the benefits of 3D echocardiography and STE: volumetric and strain assessment of the RA can be performed at the same time from the same digitally acquired 3D echocardiographic dataset with a special equipment using a virtual 3D model of the RA. A diagnostic focused study is under way at the Second Department of Medicine and Cardiology Center, University of Szeged, Hungary to assess 3D-STE-derived RA variables in different patient populations, which serves as a substudy of Motion Analysis of the heart and Great vessels bY three-dimensionAl speckle-tRacking echocardiography in Pathological cases (MAGYAR-Path) Study...

In the neonatal and pediatric intensive care setting, bedside cardiac ultrasound is often used to assess ventricular dimensions and function. Depending upon the underlying disease process, it is necessary to be able to evaluate the systolic and diastolic function of left and or right ventricles. The systolic function of left ventricle is mostly assessed qualitatively on visual inspection "eye-balling" and quantitatively by measuring circumferential fraction shortening or calculating the ejection fraction by Simpson's planimetry...

BACKGROUND: Sunitinib, used widely in metastatic renal cell carcinoma, can result in hypertension, left ventricular dysfunction, and heart failure. However, the relationships between vascular function and cardiac dysfunction with sunitinib are poorly understood. METHODS AND RESULTS: In a multicenter prospective study of 84 metastatic renal cell carcinoma patients, echocardiography, arterial tonometry, and BNP (B-type natriuretic peptide) measures were performed at baseline and at 3...

BACKGROUND: Left ventricular (LV) diastolic dysfunction (DD) is a frequent finding in obesity and may predispose to the development of heart failure (HF). However, no data are available on the prevalence of DD after the introduction of the 2016 Recommendations of the American Society of Echocardiography and the European Association of Cardiovascular Imaging. METHODS AND RESULTS: To assess the impact of the new Recommendations on the prevalence of DD and on their clinical and echocardiographic correlates in obesity, a prospective study was performed in 588 subjects with an ejection fraction (EF) ≥50% and no history of HF either obese (n = 402; mean age: 47 ± 12 years; women 71%; body mass index [BMI]: 44 ± 8 kg/m2 ), overweight (n = 86; BMI: 28 ± 1 kg/m2 ), or with a normal weight (n = 100; BMI: 22 ± 2 kg/m2 )...

BACKGROUND: The objective of this study was to investigate left ventricular (LV) circumferential strain responses to incremental cycling and isometric knee extension exercises. METHODS: Twenty-six healthy male participants (age = 30 ± 6 years) were used to study LV global (GCS) and regional circumferential strain at the apex (ACS) and base (BCS) during incremental cycling at 30% and 60% work rate maximum (Wmax ) and short-duration (15 seconds contractions) isometric knee extensions at 40% and 75% maximum voluntary contraction (MVC) using two-dimensional speckle tracking echocardiography...

Aims: It has previously been demonstrated that the ratio of early mitral inflow velocity to global diastolic strain rate (E/e'sr) is a significant predictor of cardiac events in specific patient populations. The utility of this measurement to predict cardiovascular events in a general population has not been evaluated. Methods and results: A total of 1238 participants in a general population study underwent a health examination including echocardiography where global longitudinal strain (GLS) and E/e'sr were determined...

BACKGROUND: Acute pulmonary embolism (PE) with preserved hemodynamics but right ventricular dysfunction, classified as submassive PE, carries a high risk of mortality. We report the results for patients who did not qualify for medical therapy and required treatment of submassive PE with surgical pulmonary embolectomy and catheter-directed thrombolysis (CDT).
