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)...

Aortic valve area is one of the main criteria used by echocardiography to determine the degree of valvular aortic stenosis, and it is calculated using the continuity equation which assumes that the flow volume of blood is equal at two points, the aortic valve area and the left ventricular outflow tract (LVOT). The main fallacy of this equation is the assumption that the LVOT area which is used to calculate the flow volume at the LVOT level is circular, where it is often an ellipse and sometimes irregular. The aim of this review is to explain the physiology of the continuity equation, the different sources of errors, the added benefits of using three-dimensional imaging modalities to measure LVOT area, the latest recommendations related to valvular aortic stenosis, and to introduce future perspectives...

Echocardiography plays a pivotal role as an imaging modality in the modern cardiology practice. Information derived from echocardiography is definitely helpful for a patient care. The Japanese Society of Echocardiography has promoted echocardiography for a routine clinical and research use. One of the missions of the Society is to provide information that is useful for high-quality examinations. To ensure it, we believe equipment in good conditions and a comfortable environment are important for both a patient and an examiner...

The three EBMs in the title refer to the following concepts: evidence-based medicine, experience-based medicine, and echo-based medicine. Evidence-based medicine: I have carried out the following clinical research using transthoracic Doppler echocardiography: (1) noninvasive pulsed-wave Doppler echocardiographic detection of the direction of shunt flow in patients with atrial septal defect: usefulness of the right parasternal approach (1985), (2) significance of laminar systolic regurgitant flow in patients with tricuspid regurgitation: a combined pulsed-wave, continuous-wave, and two-dimensional echocardiography (1990), (3) obstruction of the inferior vena caval orifice by the giant left atrium in patients with mitral stenosis: a Doppler echocardiographic study from the right parasternal approach (1992), and (4) demonstration of a localized acceleration flow signal in the transmural penetrating coronary artery using transthoracic color and pulsed-wave Doppler echocardiography in patients with hypertrophic cardiomyopathy (1996-2017)...

Progress in cancer therapy has led to improved prognosis of patients with cancer and thus to a continuous rise of cancer survivors. However, it has simultaneously increased cardiovascular morbidity and mortality rates due to direct and/or indirect side effects of anticancer treatment. Similar to the rapid rise of patients with adult congenital disease, the number of patients suffering or at risk of cardiotoxicity has been steeply increasing and getting an emerging issue. Among the many facets of chemotherapy-induced cardiovascular toxicity, this review attempts to summarize echocardiographic evaluation of cardiac function after cancer chemotherapy by reviewing the definition, risk factors, brief history, limitation of left ventricular ejection fraction and myocardial strain imaging, as well as the limitations of this technique...

BACKGROUND: The left atrial appendage (LAA) flow velocity is an important factor for thrombus formation in patients with non-valvular atrial fibrillation (NV-AF). Recently, the relation of plasma brain natriuretic peptide (BNP) levels and thromboembolism has been reported in patients with NV-AF. The aim of this study was to determine whether the plasma BNP is predictive of lower LAA flow velocity in patients with NV-AF and normal left ventricular (LV) systolic function. METHODS AND RESULTS: A total of 184 patients with NV-AF (132 men; 65 ± 12 years, LV ejection fraction; 65 ± 10%) underwent transthoracic echocardiography, transesophageal echocardiography (TEE), and measurement of plasma BNP...

BACKGROUND: Transesophageal Doppler echocardiography has shown that significant stenosis can be detected based on the presence of aliasing with color Doppler in the stenotic area. The study aimed to assess the detection of angiographically significant coronary stenosis (ASCS) by analyzing the characteristics and velocities of resting coronary artery flow (RCF) using transthoracic coronary Doppler echocardiography (TCDE). METHODS: TCDE was performed before diagnostic coronary angiography (CA)...

Left ventricular (LV) diastolic function can be evaluated by echocardiographic indices of LV relaxation/restoring forces, diastolic compliance, and filling pressure. By using a combination of indices, diastolic function can be graded and LV filling pressure estimated with high feasibility and good accuracy. Evaluation of diastolic function is of particular importance in patients with unexplained exertional dyspnea or other symptoms or signs of heart failure which cannot be attributed to impaired LV systolic function and to assess filling pressure in patients with heart failure and reduced LV ejection fraction...

BACKGROUND: The purpose of this study was to investigate associations between right ventricular (RV) function and left ventricular (LV) diastolic function in patients with reduced LV ejection fraction (LVEF) and preserved LVEF. METHODS: A total of 139 patients who had undergone echocardiography were recruited. LV diastolic function was determined as the ratio of mitral inflow E to mitral e' lateral annular velocities (E/e'). RV function was determined as the RV index of myocardial performance (RIMP)...

BACKGROUND: Mitral annular disjunction is a structural abnormality of the mitral annulus fibrosus and is pathologically defined by a separation between the atrial wall-mitral valve junction and the left ventricular attachment. Mitral annular disjunction can cause hypermobility of the mitral valve apparatus and is often associated with mitral valve prolapse (MVP). The aim of this study was to investigate the frequency and characteristics of mitral annular disjunction in the patients referred to an echocardiography laboratory and to compare these with previously reported pathological data...
