INTRODUCTION AND OBJECTIVES: Transesophageal echocardiography (TEE) is crucial in order to evaluate aortic anatomy after stroke. Although routinely used to assess cardiovascular anatomy and function, three-dimensional echocardiography (3D TEE) is less used for aortic evaluation. We thus sought to assess prospectively whether additional information on aortic plaque morphology could be obtained with 3D TEE after an ischemic stroke. METHODS: Patients within one week of a stroke (confirmed by brain computed tomography/magnetic resonance) underwent TEE and 3D findings were compared with two-dimensional (2D) (aorta plaque number, dimensions, area and the presence of debris and ulcerations)...

INTRODUCTION AND OBJECTIVES: Hypertrophic cardiomyopathy (HCM) is accompanied by pathophysiological changes that predispose to the development of atrial fibrillation (AF). This arrhythmia impacts negatively on the morbidity, mortality and quality of life of these patients. Our objective was to evaluate the behavior of left atrial function, by means of atrial strain (derived from speckle tracking) and volumetric analysis by three-dimensional echocardiography, in patients with HCM with paroxysmal AF...

BACKGROUND: Three-dimensional echocardiography (3D ECHO) allows the generation of a volume-time curve representative of changes in the left ventricular (LV) volume throughout the entire cardiac cycle. OBJECTIVE: This study aims to demonstrate the hemodynamic adaptations present in Chagas cardiomyopathy (CC) by means of the volume and flow measurements obtained by the volume-time curve by 3D ECHO. METHODS: Twenty patients with CC and 15 healthy subjects were prospectively enrolled in a cross-sectional design study...

BACKGROUND: Approximately 10% of infants are born preterm. Preterm birth leads to short and long-term changes in cardiac shape and function. By using a rat model of neonatal high-oxygen (80%O2 ) exposure, mimicking the premature hyperoxic transition to the extrauterine environment, we revealed a major role of the renin-angiotensin system peptide Angio II (angiotensin II) and its receptor AT1 (angiotensin receptor type 1) on neonatal O2 -induced cardiomyopathy. Here, we tested whether treatment with either orally active compounds of the peptides Angio-(1-7) or alamandine included in cyclodextrin could prevent postnatal cardiac remodeling and the programming of cardiomyopathy induced by neonatal high-O2 exposure...

BACKGROUND: Among current transcatheter therapies for the treatment of mitral regurgitation, the MitraClipTM (MC, Abbott Vascular, Illinois, USA) system is the most commonly used. MC implantation is usually contraindicated in patients with a mitral valve area (MVA) < 4.0cm2 . However, little is known about the real impact of MC implantation on MVA. Our goal was to investigate the factors influencing MVA reduction and derive the minimal MVA required to prevent the development of a clinically significant mitral stenosis (MVA < 1...

INTRODUCTION AND OBJECTIVE: Acromegaly is a rare, chronic and slowly developing endocrine disorder caused by hypersecretion of human growth hormone and consequently of insulin-like growth factor-1 during adulthood. The present study was conducted to assess mitral annular (MA) size and function between acromegalic patients and age- and gender-matched healthy controls by three-dimensional speckle-tracking echocardiography (3D-STE). It also aimed to examine whether activity of the disease has any effect on MA parameters...

Echocardiography represents a first level technique for the evaluation of coronary artery disease (CAD) which supports clinicians in the diagnostic and prognostic workup of these syndromes. However, visual estimation of wall motion abnormalities sometimes fails in detecting less clear or transient myocardial ischemia and in providing accurate differential diagnosis. Speckle tracking echocardiography (STE) is a widely available noninvasive tool that could easily and quickly provide additive information over basic echocardiography, since it is able to identify subtle myocardial damage and to localize ischemic territories in accordance to the coronary lesions, obtaining a clear visualization with a "polar map" useful for differential diagnosis and management...

La estimulación apical permanente del ventrículo derecho (VD) puede producir asincronía del ventrículo izquierdo (VI) desde los puntos de vista eléctrico y mecánico. Este fenómeno es efecto de una alteración de la activación normal del VI que lleva al deterioro de la función sistólica y la aparición de insuficiencia cardíaca y sus efectos deletéreos relacionados. Para el estudio de la asincronía eléctrica del VI se ha propuesto en fecha reciente el nuevo sistema electrocardiográfico no invasivo Synchromax, que puede cuantificar el grado de asincronía eléctrica que causa una subsecuente asincronía mecánica...

Congenital malformations of the aortic arches are a heterogeneous group of diseases associated with developmental disorders of the primitive branchial arches during fetal life. The coarctation of the aorta is a common congenital vascular malformation which is a congenital narrowing of the aortic isthmus, a segment of the aorta between the left subclavian artery and the ductus arteriosus. The interruption of the aortic arch is considered by some authors as an extreme coarctation of the aorta, characterized by discontinuity between ascending and descending aorta...

BACKGROUND: Whether echocardiography platform and analysis software impact left ventricular (LV) volumes, ejection fraction (EF), and stroke volume (SV) by transthoracic tridimensional echocardiography (3DE) has not yet been assessed. Hence, our aim was to compare 3DE LV end-diastolic and end-systolic volumes (EDV and ESV), LVEF, and SV obtained with echocardiography platform from 2 different manufacturers. METHODS: 3DE was performed in 84 patients (65% of screened consecutive patients), with equipment from 2 different manufacturers, with subsequent off-line postprocessing to obtain parameters of LV function and size (Philips QLAB 3DQ and General Electric EchoPAC 4D autoLVQ)...

The recent technical advances allow the use in practice of three-dimensional echocardiography in children especially through the new high frequency matrix probe. It is difficult or even impossible to hold breathing during children' acquisition so to avoid motion full volume artifact, one beat and live 3D modes are suitable. 3D echocardiography is more accurate than 2D to assess the size, location, and relationship with surrounding structures of atrial and ventricular septal defects and thus helps in the therapeutic decision...

Hypertension is a major cardiovascular (CV) risk factor and elevated blood pressure poses a significant burden for the whole CV hemodynamics. Along the last decades different techniques and resources have been developed, including ultrasound´s M-mode and B-mode, spectral Doppler, tissue Doppler and color Doppler. Techniques from newer resources as speckle tracking, twist and tridimensional ultrasound are continuously being inserted in the echocardiography labs routine around the world. Many of the older and newer techniques interpretation have a subject component from the echocardiographer...

BACKGROUND: Aortic regurgitation is mainly evaluated by trans-thoracic echocardiography using multi-parametric qualitative and semi quantitative tools. All those parameters can fail to meet expectations, resulting in an imperfect diagnostic reliability and assessment of aortic regurgitation severity can be challenging.

Nowadays computed tomography, cardiac magnetic resonance imaging, and tridimensional transoesophageal echocardiography provide anatomic images of right-atrial structures with an impressive richness of anatomical details. It is therefore surprising that these techniques are not routinely used as complementary tools in teaching anatomy. This review aims to fill this gap showing the normal anatomy of right atrium as displayed by these sophisticated imaging techniques. A better understanding of right-atrial anatomy is crucial for the treatment of primary right-atrium electrical disorders as well as for catheter-based interventions for structural heart disease...

A 60-year old male patient with multiple risk factors and two previous interventions over the mitral valve was admitted to the emergency unit with symptoms of cardiac failure. Initial examination revealed a competent mitral bioprosthesis with severe perivalvular mitral insufficiency. Based on previous experiences with transapical procedures, a transapical transcatheter closure of the perivalvular leak was performed. The apex was punctured with a 7 French introducer sheath, and a hydrophilic guidewire was advanced with the aid of a right Judkins catheter and positioned across the defect in the left atrium...
