BACKGROUND: Functional tricuspid regurgitation (TR) with a structurally normal tricuspid valve (TV) may occur secondary to chronic atrial fibrillation (AF). However, the clinical and echocardiographic differences according to functional TR subtypes are unclear. Therefore, characterization of functional TR because of chronic AF (AF-TR) remains undetermined. METHODS AND RESULTS: To investigate the prevalence of AF-TR, 437 patients with moderate to severe TR underwent 3-dimensional (3D) transesophageal echocardiography...

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...

The newly developed three dimensional speckle-tracking echocardiography (3D-STE) technology provides quick and comprehensive quantitative assessment of biventricular myocardial dynamics. The impact of coronary slow flow phenomenon (CSFP) on biventricular functions has not been comprehensively evaluated using this new technology. Therefore, the aim of this study was to evaluate the effects of CSFP on biventricular systolic functions using 3D-STE. Forty patients with CSFP and otherwise normal coronary arteries (NCAs) and 40 age- and sex-matched controls with normal coronary angiograms (CAGs) were prospectively enrolled...

Interventional cardiac catheterization has a major place in the management of congenital heart disease. Since the Rashkind atrioseptostomy in mid-1960s, many techniques have been developed. For some, it is necessary to close a cardiac or extracardiac shunt using occluder (double disc system, plug, coil…): closure of atrial septal defect, ventricular septal defect or patent arterial duct. For others, it is necessary to treat a valvular or vascular stenosis using a balloon catheter: dilatation of the pulmonary or the aortic valve, dilatation of aortic coarctation...

AIMS: Left ventricular activation delay due to left bundle branch block (LBBB) is an important determinant of the severity of dyssynchronous heart failure (DHF). We investigated whether patient-specific computational models constructed from non-invasive measurements can provide measures of baseline dyssynchrony and its reduction after CRT that may explain the degree of long-term reverse ventricular remodelling. METHODS AND RESULTS: LV end-systolic volume reduction (ΔESVLV) measured by 2D trans-thoracic echocardiography in eight patients following 6 months of CRT was significantly (P < 0...

Left ventricular pseudoaneurysm (LVPA) after mitral valve replacement (MVR) is a rare condition. The diagnosis of LVPA may be difficult, and for accurate diagnosis, two-dimensional (2D) transthoracic echocardiography (TTE) should be used in combination with other imaging modalities such as multiple detector computed tomography (MDCT) and three-dimensional (3D) TTE. Herein is presented a late type of post-MVR pseudoaneurysm in a 72-year-old female who was admitted to the authors' emergency department with complaints of dyspnea...

BACKGROUND: Diastolic dysfunction is a major cause of morbidity in obese individuals. We aimed to assess the ability of magnetic resonance imaging (MRI) derived left atrial (LA) strain to detect early diastolic dysfunction in individuals with obesity and type 2 diabetes, and to explore the association between cardiac adipose tissue and LA function. METHODS: Twenty patients with obesity and T2D (55 ± 8 years) and nineteen healthy controls (48 ± 13 years) were imaged using cine steady state free precession and 2-point Dixon cardiovascular magnetic resonance...

OBJECTIVE: High levels of ACPAs in RA are associated with more severe arthritis and worse prognosis. However, the role of ACPAs in mediating the increased risk of heart failure in RA remains undefined. We examined whether specific ACPAs were associated with subclinical left ventricular (LV) phenotypes that presage heart failure. METHODS: Sera from RA patients without clinical cardiovascular disease were assayed for specific ACPAs using a custom Bio-Plex bead assay, and their cross-sectional associations with cardiac magnetic resonance-derived LV measures were evaluated...

Aortic valve infective endocarditis (IE) can be complicated with severe aortic regurgitation (AR) jet-related lesions such as vegetations, pseudoaneurysms, aneurysms or perforations on the anterior mitral leaflet. Herein is reported the case of a 69-year-old male with culture-negative aortic valve endocarditis complicated with aortic valve perforations resulting in severe and eccentric AR and an AR jet-related ventricular septal defect (VSD). Neither transthoracic echocardiography (TTE) nor two-dimensional transesophageal echocardiography (2D-TEE) were unable to clearly discriminate an aorto-right ventricular fistula from a VSD...

Three-dimensional (3D) printing is a rapidly evolving technology with several potential applications in the diagnosis and management of cardiac disease. Recently, 3D printing (i.e. rapid prototyping) derived from 3D transesophageal echocardiography (TEE) has become possible. Due to the multiple steps involved and the specific equipment required for each step, it might be difficult to start implementing echocardiography-derived 3D printing in a clinical setting. In this review, we provide an overview of this process, including its logistics and organization of tools and materials, 3D TEE image acquisition strategies, data export, format conversion, segmentation, and printing...
