To assess the value of three-dimensional speckle tracking echocardiography (3D STE) in evaluating the left ventricular (LV) function in hyperuricemia patients. We enrolled 15 healthy controls and 40 hyperuricemia patients and collected and analyzed full-volume 3D STE images of the left ventricle in the apical four-chamber heart view. Laboratory tests and 3D STE parameters, including left ventricular ejection fraction, left ventricular end-diastolic volume, left ventricular end-systolic volume, stroke volume (SV), global longitudinal strain (GLS), and global circumferential strain (GCS), were compared between hyperuricemia patients and healthy controls...

Background Athlete's heart is a term used to describe the morphological and functional changes in the hearts of athletes. Recent studies suggest that these changes may occur even in preadolescent athletes. This study aims to improve our understanding of the changes occurring in the preadolescent athlete's heart. Design and methods Cardiac morphology and function in 76 preadolescent cross-country skiers (aged 12.1 ± 0.2 years) were compared with 25 age-matched non-competing preadolescents. Echocardiography was performed in all subjects, including 2D speckle-tracking strain echocardiography and 3D echocardiography...

The indications for catheter-based structural and electrophysiological procedures have recently expanded to more complex scenarios, in which an accurate definition of the variable individual cardiac anatomy is key to obtain optimal results. Intracardiac echocardiography (ICE) is a unique imaging modality able to provide high-resolution real-time visualization of cardiac structures, continuous monitoring of catheter location within the heart, and early recognition of procedural complications, such as pericardial effusion or thrombus formation...

Normal pediatric values of three-dimensional (3D) left ventricular (LV) volumes and strain are not well established; moreover, no reports exist of the stress-strain relation and the heart rate-corrected velocity of circumferential fiber shortening (VCFc) based upon 3D imaging in children. Three-dimensional LV datasets were obtained in pediatric patients (≤18 years of age) with structurally normal hearts. Ventricular volumes and strain components (longitudinal, GLS; circumferential, GCS; and 3D strain, 3DS) were analyzed using a commercial 3D speckle-tracking analysis package...

The natural history of mitral regurgitation (MR) results in significant morbidity and mortality. Innovations in non-invasive imaging have provided new insights into the pathophysiology and quantification of MR, in addition to early detection of left ventricular (LV) dysfunction and prognostic assessment in asymptomatic patients. Transthoracic (TTE) and transesophageal (TOE) echocardiography are the mainstay for diagnosis, assessment and serial surveillance. However, the advance from 2D to 3D imaging leads to improved assessment and characterization of mitral valve (MV) disease...

Mitral annuloplasty ring thrombosis is an extremely infrequent pathology, for which no evidence-based antithrombotic management has yet been described. Herein is presented a case of heterozygous Factor V Leiden (FVL) and hyperhomocysteinemia with homozygous methylenetetrahydrofolate reductase (MTHFR) mutations that caused early thrombosis of the mitral annuloplasty ring. The clinical management and antithrombotic treatment of the patient, and the implications of hyperhomocysteinemia, are discussed.

BACKGROUND: Segmental analysis of diseased mitral valves is important to predict a successful surgical valve repair. An assessment was made of the comparative accuracy of intraoperative three-dimensional (3D) and two-dimensional (2D) transesophageal echocardiography (TEE) in the evaluation of mitral valve lesions when compared with intraoperative surgical segmental analysis. METHODS: A total of 42 consecutive patients (12 females, 30 males; mean age 70.5 ± 14 years) with severe mitral valve regurgitation due to degenerative disease and who underwent mitral valve repair was enrolled in the study...

Despite its proven superiority over two-dimensional transthoracic echocardiography (2DTTE) for left ventricular (LV) volumes and ejection fraction, clinical use of 3DTTE remains very limited in the acute setting. 3DTTE may have significant clinical advantages in the assessment of acute heart failure. Further exploration of 3DTTE utilization may help in more precise assessment of the regional wall-motion abnormalities, early identification of acute ischemic from nonischemic LV dysfunction with a more precise approach to the AHF management...

BACKGROUND: Mitral regurgitation in ischemic heart disease (IMR) is a strong predictor of outcome but until now, pathophysiology is not sufficiently understood and treatment is not satisfying. We aimed to systematically evaluate structural and functional mitral valve leaflet and annular characteristics in patients with IMR to determine the differences in geometric and dynamic changes of the MV between significant and mild IMR. METHODS: Thirty-seven patients with IMR (18 mild (m)MR, 19 significant (moderate+severe) (s)MR) and 33 controls underwent TEE...

BACKGROUND: Functional impairment of the aorta is a recognized complication of aortic and aortic valve disease. Aortic strain measurement provides effective quantification of mechanical aortic function, and 3-dimenional (3D) approaches may be desirable for serial evaluation. Computerized tomographic angiography (CTA) is routinely performed for various clinical indications, and offers the unique potential to study 3D aortic deformation. We sought to investigate the feasibility of performing 3D aortic strain analysis in a candidate population of patients undergoing transcatheter aortic valve replacement (TAVR)...

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...

PURPOSE: Transcatheter aortic valve replacement (TAVR) is a minimally invasive procedure in which a prosthetic heart valve is placed and expanded within a defective aortic valve. The device placement is commonly performed using two-dimensional fluoroscopic imaging. Within this work, we propose a novel technique to track the motion and deformation of the prosthetic valve in three dimensions based on biplane fluoroscopic image sequences. METHODS: The tracking approach uses a parameterized point cloud model of the valve stent which can undergo rigid 3D transformation and different modes of expansion...

BACKGROUND: Previous studies have demonstrated that three-dimensional (3D) transesophageal echocardiography (TEE) is an alternative to multi-detector computed tomography (MDCT) for aortic valve sizing in transcatheter aortic valve replacement (TAVR). However, conventional cross-sectional analysis of aortic annulus by 3D TEE has some limitations such as lengthy analytical time. A novel software for automated valve measurement has been developed for 3D TEE. We evaluated the accuracy and analytical time of aortic annular measurements using this novel automated software in the clinical setting...

The right ventricle and tricuspid valve (TV) have long been neglected by cardiologists. Functional tricuspid regurgitation (TR) is nowadays the most common cause of severe TR and is emerging as a prognostic factor in many heart diseases. A multimodality imaging approach is fundamental for defining the pathophysiology of TR, using both 2-dimensional and 3-dimensional (3D) echocardiography, as well as CT scan. In particular, 3D echocardiography can characterize TV apparatus and tricuspid annulus; CT offers complementary information about annular structure, and its relationship with the right coronary artery...

Background: Left ventricular remodeling (LVR) after ST-elevation myocardial infarction (STEMI) harbingers poor prognosis. Three-dimensional echocardiography (3DE) is more accurate than 2 D echo for the assessment of left ventricle (LV) shape. We assessed LV geometry with 3D ECHO 6 months after STEMI in patients who had primary angioplasty. Materials and Methods: In this prospective study, morphological and functional analysis of LV with 3D ECHO (volumes, LVEF, 3D sphericity index [SI]) was assessed up to 7 days and 6 months in 42 STEMI patients...
