Detection of an intracardiac mass always represents a clinical challenge. We present a 61-year-old female patient with symptoms of New York Heart Association class III. Two-dimensional transthoracic echocardiography revealed a hypoechogenic mass in the cavity of the dilated right ventricle (RV). Cardiac MRI described a pathologic structure of the RV free wall with pedunculated tumor in its cavity. Three months later, on a repeated echocardiography, there were three individual masses. The patient underwent surgery and the pathohistologic report demonstrated thrombotic masses...

An 84-year-old man with cardial senile amyloidosis and severe tricuspid regurgitation was referred for right sided heart failure symptoms. The patient was scheduled for a percutaneous treatment due to the prohibitive risk of surgery. Two MitraClips were implanted using a transjugular approach with successful echocardiographic and clinical results. This case shows the rational of the procedural with a bicuspidalization of the valve demonstrated at the three dimensional transesophageal echocardiography.

Bicuspid aortic valve (BAV) is a common congenital cardiac anomaly, and rarely, it is associated with sinus of Valsalva aneurysms (SOVAs). And very infrequently, these SOVAs rupture into left side of heart. We hereby report a case of 12-year-old male with BAV with severe aortic stenosis with a large SOVA that ruptured into the left side of the heart. The anatomy was delineated with multimodality imaging; initially with two-dimensional trans-thoracic echocardiography (TTE), and later on with three-dimensional TTE and with multi detector computed tomography...

We present the primary report of a paediatric patient who had placement of the MitraClip device for severe functional mitral regurgitation. The patient was a 14-year-old boy with symptomatic end-stage non-compaction type cardiomyopathy secondary to a mitochondrial cytopathy. He had severe mitral regurgitation, tricuspid valve regurgitation, a severely dilated LV with apical non-compaction, severe LV dysfunction and severe pulmonary hypertension. Despite optimal medical therapy he developed progressive symptoms of congestive heart failure and he was not a candidate for an assist device or cardiac transplantation...

BACKGROUND: Increased left atrial (LA) dimensions are known to be a risk factor in predicting cardiovascular events and mortality and to be one key diagnostic tool to assess diastolic dysfunction. Currently, LA measurements are usually conducted using 2D-echocardiography, although there are well-known limitations. Real-time 3D-echocardiography is able to overcome these limitations, furthermore being a valid measurement tool compared to reference standards (e.g. cardiac magnetic resonance imaging)...

The analysis of full Left Atrium (LA) deformation and whole LA deformational trajectory in time has been poorly investigated and, to the best of our knowledge, seldom discussed in patients with Hypertrophic Cardiomyopathy. Therefore, we considered 22 patients with Hypertrophic Cardiomyopathy (HCM) and 46 healthy subjects, investigated them by three-dimensional Speckle Tracking Echocardiography, and studied the derived landmark clouds via Geometric Morphometrics with Parallel Transport. Trajectory shape and trajectory size were different in Controls versus HCM and their classification powers had high AUC (Area Under the Receiving Operator Characteristic Curve) and accuracy...

INTRODUCTION: Quantification of mitral regurgitation (MR) by two-dimensional (2D) transthoracic echocardiography (TTE) is based on the analysis of the proximal flow convergence (PFC) and the "vena contracta" (VC). This method assumes geometries and can be misleading. In contrast, three-dimensional (3D) echocardiography directly measures flow volumes and does not assume geometries, which allows for more accurate MR evaluation. AIMS: To report the 3D transesophageal echocardiography (3DTEE) feasibility for MR quantification and evaluate its concordance with 2D echo...

Multi-imaging modalities should be considered in patients with atrial septal defects (ASDs) in which the degree of right ventricular enlargement is not fully explained by the small size of ASD found on conventional transthoracic echocardiography. We report a case of crescent-shaped superior sinus venosus ASD discriminated using real-time three-dimensional transesophageal echocardiography. MDCT confirmed its relationship with the superior vena cava and the absence of combined anomalies, such as the pulmonary venous return anomaly...

BACKGROUND AND AIM: Decreased vascular reactivity in atherosclerosis was previously shown. In our study, it was aimed to demonstrate the decreased vascular functions in both microvascular and macrovascular tissues and to estimate any correlation between them. METHODS: Twenty-five control outpatients with no coronary artery disease (CAD) history and 26 outpatients with CAD history were enrolled in the study. Local cutaneous post-occlusive reactive hyperemia (PORH) responses after three minutes of brachial occlusion with a pneumatic cuff were recorded noninvasively by a Perimed Periflux 5010 laser Doppler flow system...

BACKGROUND: Left ventricular (LV) dysfunction may complicate paediatric cardiac surgery with cardiopulmonary bypass, notably after long aortic cross-clamping (ACC). Assessment of occult myocardial injury by conventional echocardiographic variables may be difficult in the postoperative period. AIMS: To evaluate the feasibility of two-dimensional (2D) strain in the postoperative period, and to assess the effect of ACC duration on this variable. METHODS: Thirty-three paediatric patients (age<18years) with congenital heart disease undergoing cardiac surgery with cardiopulmonary bypass were included in this prospective single-centre study...

We report a case of cyst was initially labeled as left ventricular noncompaction cardiomyopathy. An accurate diagnosis is essential to establish the most effective treatment strategy. In particular, echocardiographic examination assists in identifying the correct diagnosis. In this case, two-dimensional and three-dimensional echocardiography and computed tomography were used for definitive diagnosis of cardiac hydatid cyst.

Missense single-nucleotide polymorphisms (mSNPs) in titin are emerging as a main causative factor of heart failure. However, distinguishing between benign and disease-causing mSNPs is a substantial challenge. Here, we research the question of whether a single mSNP in a generic domain of titin can affect heart function as a whole and, if so, how. For this, we studied the mSNP T2850I, seemingly linked to arrhythmogenic right ventricular cardiomyopathy (ARVC). We used structural biology, computational simulations and transgenic muscle in vivo methods to track the effect of the mutation from the molecular to the organismal level...

PURPOSE: Pulmonary vein isolation using cryoballoon ablation is an established approach to treating atrial fibrillation. The procedure involves insertion of a 15-Fr sheath into the left atrium across the interatrial septum. This creates an iatrogenic atrial septal defect, which may have important long-term clinical relevance, especially in younger patients. We sought to determine the long-term incidence of these defects and determine the direction of shunt using contrast transesophageal echocardiography...

In this paper, the authors attempt to concisely present the anatomical and pathophysiological bases as well as the principles for echocardiographic evaluation of mechanical aspects of cardiac function based on speckle tracking method. This technique uses a phenomenon involving the formation of characteristic image units, referred to as speckles or acoustic markers, which are stable during cardiac cycle, on a two-dimensional echocardiographic picture. Changes in the position of these speckles throughout the cardiac cycle, which are monitored and analyzed semi-automatically by a computer system, reflect deformation of both, cardiac ventricle as a whole as well as its individual anatomical segments...

OBJECTIVES: Mitral valve repair performed by an experienced surgeon is superior to mitral valve replacement for degenerative mitral valve disease; however, many surgeons are still deterred from adapting this procedure because of a steep learning curve. Simulation-based training and planning could improve the surgical performance and reduce the learning curve. The aim of this study was to develop a patient-specific simulation for mitral valve repair and provide a proof of concept of personalized medicine in a patient prospectively planned for mitral valve surgery...

BACKGROUND: Catheter ablation has been used to manage supraventricular arrhythmia in children since 1990. This article reviews the history of catheter ablation used to treat arrhythmia in children and discusses new frontiers in the field. We also address ablation in adult patients with a history of congenital heart disease (CHD) that was diagnosed and initially treated in childhood. METHODS: We conducted an evidence-based literature review to gather available data on ablation for supraventricular tachycardia in children and adult patients with CHD...

OBJECTIVES: Previous studies using transthoracic echocardiography (TTE) observed moderate heritability of aortic root dimensions. Computed tomography angiography (CTA) might provide more accurate heritability estimates. Our primary aim was to assess the heritability of the aortic root with CTA. Our secondary aim was to derive TTE-based heritability and compare this with the CTA-based results. METHODS: In the BUDAPEST-GLOBAL study 198 twin subjects (118 monozygotic, 80 dizygotic; age 56...
