Assessment of right chamber function has become increasingly popular and important in recent decades, complementing the evaluation of left chamber functional parameters. The late adoption and integration of right ventricular (RV) function into a complete evaluation of cardiac function could be due in part to the difficulty in visualization of the whole right ventricle, inconsistency in the analysis of RV parameters, and poor understanding of the impact of RV function on prognosis. From M-mode to 2-dimensional (2D) measurements of RV size and function, there have been arrays of parameters that provide important information of the right ventricle...

BACKGROUND: In dogs, due to better alignment with the aortic outflow, the subcostal (SC) transducer site provides greater Doppler-derived velocities than those obtained from the left parasternal view. The feasibility of this imaging approach has never been described in equine echocardiography. OBJECTIVES: To evaluate the feasibility of the SC view in newborn foals and compare aortic two-dimensional and Doppler-derived velocity measurements with those of standard parasternal long-axis (LAX) views...

BACKGROUND: The relation between systolic pulmonary pressure (sPAP) and left atrium in patients with heart failure (HF) is unclear. Diastolic dysfunction, expressed as restrictive mitral filling pattern (RMP), and functional mitral regurgitation (FMR) are associated with both LA enlargement and increased sPAP. We aimed to evaluate whether atrial dilation might modulate the consequences of RMP and FMR on the pulmonary circulation of patients with HF with reduced ejection fraction (HFrEF)...

Rheumatic heart disease causes a significant number of morbidity and mortality in Bangladesh. Although the mitral and the aortic valve are the two most involved valves in rheumatic heart disease, the tricuspid valve disease is not uncommon secondary to, or in association with, mitral or aortic valve disease, but receives less attention as compared to the primary left-sided valve disease. Appropriate treatment of the tricuspid valve disease may improve long-term functional outcome. But the pattern and extent of the tricuspid valve involvement was not studied recently...

BACKGROUND: Hypertension is strongly related to arterial stiffness in a cause-effect fashion. Diabetes mellitus is also thought to determine vascular damage, mostly by means of advanced glycosylation end-products (AGEs). Aim of our study was to study the role of type 2 diabetes mellitus (T2DM) as regard ascending aortic elastic properties in hypertensive patients. METHODS: We prospectively enrolled outpatients with hypertension (n = 99) and type 2 diabetes mellitus plus hypertension (n = 42) without cardiovascular events...

Variability related to image acquisition and interpretation is an important issue of echocardiography in clinical trials. Nevertheless, there is no broadly accepted standard method for quality assessment of echocardiography in clinical research reports. We present analyses based on the echocardiography quality-assurance program of the ongoing STAAB cohort study (characteristics and course of heart failure stages A-B and determinants of progression). In 43 healthy individuals (mean age 50 ± 14 years; 18 females), duplicate echocardiography scans were acquired and mutually interpreted by one of three trained sonographers and an EACVI certified physician, respectively...

OBJECTIVE: M-mode and 2D have been proposed for evaluating fetal myocardial thickness. However, studies comparing the performance of both modalities are lacking. We aimed to compare 2D versus M-mode reproducibility for assessing myocardial wall thicknesses. METHODS: A prospective study including 45 healthy fetuses from low-risk pregnancies evaluated between 18 and 41 weeks of gestation. Left and right ventricular free-wall and septal myocardial thicknesses were measured at end-diastole (ED) and end-systole (ES) in transverse 4-chamber view using 2D and M-mode...

Background: Right ventricular infarction (RVI) develops in 30-50% of patients with inferior wall infarction (IWI). The rates of mortality, morbidity, and complications in these patients are greater than in the patients without RVI. We compared the tissue Doppler imaging (TDI) indices between a group of patients with IWI and RVI, with a similar group of patients who had IWI alone to investigate the application of TDI indices in the evaluation and detection of right ventricular function...

Echocardiography is an invaluable tool for characterizing cardiac structure and function in vivo. Technological advances in high-frequency ultrasound over the past 3 decades have increased spatial and temporal resolution, and facilitated many important clinical and basic science discoveries. Successful reverse translation of established echocardiographic techniques, including M-mode, B-mode, color Doppler, pulsed-wave Doppler, tissue Doppler and, most recently, myocardial deformation imaging, from clinical cardiology into the basic science laboratory has enabled researchers to achieve a deeper understanding of myocardial phenotypes in health and disease...

Respiratory muscle weakness frequently occurs in patients with neuromuscular disease. Measuring respiratory function with standard pulmonary function tests provides information about the contribution of all respiratory muscles, the lungs and airways. Imaging potentially enables the study of different respiratory muscles, including the diaphragm, separately. In this review, we provide an overview of imaging techniques used to study respiratory muscles in neuromuscular disease. We identified 26 studies which included a total of 573 patients with neuromuscular disease...

Tricuspid annular plane systolic excursion (TAPSE) is a robust measure of RV function, but the performance of transesophageal echocardiography (TEE) measured TAPSE during surgery is not well established. We aim to evaluate feasibility of various TEE views before, during and after surgery. Furthermore, we compare performance of individual TEE measurements depending on view and method (AMM- and M-mode as well as 2D) as well as TAPSE measured using TEE with transthoracic echocardiography (TTE) TAPSE. The study was conducted from January 2015 through September 2016...

We investigated whether the interatrial septal (IAS) motion of each heartbeat which is observed by transesophageal echocardiography reflects left atrial pressure (LAP) in patients with atrial fibrillation (AF). We studied 100 patients (70 males, age 67 ± 9 years) who underwent catheter ablation for AF. The amplitude of IAS motion was measured using M-mode and averaged for five cardiac cycles. Left and right atrial pressures, the left to right atrial pressure gradient were directly measured during the catheter ablation...
