• DCRV may be an incidental finding in asymptomatic adults. • DCRV may be unmasked by acquired cardiac conditions. • PS-type murmur with RVH on electrocardiogram should raise suspicion for DCRV.

To exemplify the significance of the use of multichamber strain, we have provided some illustrations of common cardiac problems. The recently published European Association of Cardiovascular Imaging (EACVI) consensus document for standardization of RV, RA, and LA strain, using the currently available software, has fulfilled the aspirations of investigators world over who have been studying atrial strain using a bailed-out algorithm designed principally to quantify left ventricular deformation.

However, data are scant regarding the value of biventricular and bi-atrial deformation in association with comorbidities in heart failure with reduced left ventricular ejection fraction (HFREF).
Methods And Results: Forty-nine subjects (72 ± 13 years; 28 male) with HFREF and 14 age-matched controls underwent deformation imaging including LV global longitudinal strain (LVGLS%), right ventricular strain (RVS%), and left atrial reservoir strain (LARS%).

Purpose Of Review: Three-dimensional (3D) echocardiography (3DE) and 4-dimensional echocardiography (4DE), also known as real-time (RT) 3DE (RT3DE), are rapidly emerging technologies which have made significant impact in the clinical arena over the years. This review will discuss the recent applications of 3DE in diagnosing and treating different types of cardiovascular disease.
Recent Findings: Recent studies using 3DE expanded on prior findings and introduced additional applications to different cardiac conditions.
Background: Down's syndrome (DS) is a genetic anomaly, which undergoes increased morbidity and mortality when associated with congenital heart disease (CHD). The aims of the study were to determine the prevalence of CHD and pulmonary hypertension (PH) in DS.
Methods: One hundred twenty-seven patients with DS living in Mexico City were evaluated by physical exam, electrocardiogram and echocardiogram.
Background: While speckle tracking echocardiography (2DSTE) can be used to study longitudinal, circumferential, and radial function, real time 3D echocardiography (3DE) generates dynamic time-volume curves, offering a wide array of new parameters for characterizing mechanical and volumetric properties of the left ventricle (LV). Our aim was to investigate the merit of these new techniques to separate normal from abnormal echocardiograms as well as to identify subclinical disease in reportedly normal subjects.
Methods: Eighty-one patients (mean age 61 ± 16 years) underwent standard 2D echocardiography (2DE) enhanced by 2DSTE and 3DE.
Background: Role of biomarkers in ST-segment elevation myocardial infarction (STEMI) is paramount, as they aid in diagnosis and gauge prognosis of the disease. In this project, we sought to study the short-term outcome and clinical associates of N-terminal pro-brain natriuretic peptide (NT-proBNP) in the setting of STEMI at a tertiary center in India.
Methods: In all, 173 STEMI patients (mean age: 57 ± 12 years, 38 women) had their NT-proBNP assayed in addition to troponins and high-sensitive C-reactive protein.
M-Mode echocardiography, 2-D grey scale imaging and standard Doppler that constitute conventional echocardiography has been used for over many decades now. Although these modalities form the backbone in routine clinical echocardiography, its inability to objectively quantify left ventricular function at regional and global levels as well as its loading and heart rate dependency make conventional echocardiography an incomplete tool in clinical situations. Tissue Doppler imaging (which includes myocardial velocity, displacement and strain) has been successfully used in a variety of clinical situations, from investigations of diastolic function to implantation of bi-ventricular pacing for cardiac resynchronization therapy and even in preclinical diagnosis of genetic diseases such as hypertrophic cardiomyopathy.

Methods And Results: Twenty-nine patients (56 +/- 12 years) with a history of recent acute coronary events (ACE) underwent STE-DSE. Left ventricular images, sampled at frame rates 70-100 Hz, were analysed off-line (Echopac BT 6.
Cardiac hemangiomas are rare tumors, accounting for only 2.8% of all benign primary cardiac tumors and occur at any age. Clinical presentations vary depending on the tumor location (myocardial, endocardial or pericardial).

Methods: Real-time three-dimensional echocardiography (RT3DE) and cardiac magnetic resonance imaging (CMR) were used to determine the relative contribution of each error source in normal controls (n = 35) and patients with myocardial infarctions (MIs) (n = 34). LV volumes and EFs were calculated using (1) apical biplane disk summation on 2DE (IP + GA + BT errors), (2) biplane disk summation on RT3DE (GA + BT errors), (3) 4-multiplane to 8-multiplane surface approximation on RT3DE (GA + BT errors), (4) voxel-based surface approximation on RT3DE (BT error alone) and (5) CMR.
Background: Assessment of right ventricular function by 2-dimensional echocardiography (2DECHO) is difficult because of its complex shape. Real-time 3-dimensional echocardiography (RT3DECHO) may be superior.
Methods: End-diastolic volume, end-systolic volume, stroke volume, and ejection fraction obtained by 2DECHO, RT3DECHO short-axis disk summation (DS), and RT3DECHO apical rotation were compared with cardiac magnetic resonance imaging in 71 healthy individuals.
Background: Left ventricular hypertrophy (LVH) is a common condition that carries an increased risk of cardiovascular events. Use of ECG in detection of LVH is limited because of the reported low sensitivity. Conventional echocardiographic techniques used as the standard for estimating left ventricular (LV) mass have limitations related to the position of the image plane and shape of the ventricle.

Objectives: We defined the effects of the operative (OP) state and phenylephrine challenge on the assessment of mitral regurgitation (MR) severity.
Methods: In all, 57 patients underwent transesophageal echocardiographic assessment of MR severity pre-OP (PREOP) and intra-OP. MR severity was assessed PREOP under conscious sedation and intra-OP with general anesthesia, before and after hemodynamic manipulation with vasoactive agents, to match intra-OP and PREOP transesophageal echocardiographic mean arterial blood pressures.
Primary cardiac lymphomas are rare. They can be detected incidentally during echocardiography or cardiac operation. They can have various clinical manifestations.

(2) Increasing severity of chronic MR will result in symmetric enlargement of the mitral annulus as measured by annular shape indices.
Background: Limited data exist on mitral annular remodeling for patients with MR.
