According to the WHO, hypertension is one of the major causes of death worldwide. It leads to a number of severe complications. Diastolic heart failure, that is heart failure with preserved ejection fraction (HFPEF), is especially common. New, but simple, indices for the early detection of patients who have not yet developed complications or are in their early developmental stages are still searched for. AIM: The aim of this study is to examine the correlation between pulse wave velocity (PWV) and markers of diastolic heart failure (DHF) assessed in echocardiography in patients with hypertension and no symptoms of heart failure...

BACKGROUND: Echocardiography is a valuable noninvasive technique to estimate cardiac output (CO) from the left ventricle (LV) not only in clinical practice but also in small-animal experiments. CO is used to grade cardiac function and is especially important when investigating cardiac injury (e.g., myocardial infarction [MI]). Critically, MI deforms the LV, invalidating the assumptions fundamental to calculating of cardiac volumes directly from the LV. Thus, the purpose of this study was to determine if Doppler-derived blood flow through the pulmonary trunk (pulmonary flow [PF]) was an improved method over conventional LV-dependent echocardiography to accurately determine CO after MI...

Although measurement of right ventricular ejection fraction (RVEF) may be relevant for evaluation of therapeutic efficacy and/or prognosis in patients with pulmonary hypertension, RVEF obtained by echocardiography has limited accuracy. In contrast, radionuclide and/or magnetic resonance imaging can measure RVEF more reliably. In this study, we investigated the relationship between RVEF measured by radionuclide angiography and the echocardiographic parameters that are recommended by the American Society of Echocardiography as representative of right heart function...

Pulmonary arterial pressure is an important index in cardiovascular disorders, especially for pulmonary hypertension (PH). Doppler echocardiography (DE) is widely used as a noninvasive method to assess pulmonary arterial pressure. However, recent studies have found several hemodynamic factors that affect its accuracy in estimating systolic pulmonary arterial pressure (sPAP). But the effect of tricuspid regurgitation (TR) has not been investigated. Therefore, our study is aimed to determine whether the severity of TR will affect the accuracy of sPAP measured by DE in an unselected patient population...

BACKGROUND: Early fetal echocardiography (FE), performed at 12 to 16 weeks' gestational age (GA), can be used to screen for fetal heart disease akin to that routinely performed in the second trimester. The efficacy of FE at earlier GAs has not been as well explored, particularly with recent advances in ultrasound technology. The aim of this study was to evaluate the efficacy of early FE in assessing fetal heart structure, and the added benefit of color Doppler (CD), from as early as 6 weeks through to 13(+6) weeks' GA...

BACKGROUND: Echocardiographically estimated pulmonary artery systolic pressure (PASP) is a non-invasive widely available method that is used to estimate pulmonary arterial pressure. Although elevated PASP predicts mortality in patients with hypertrophic cardiomyopathy (HCM), the relationship between PASP and embolic events is unclear. This study aimed to determine whether elevated PASP is associated with stroke and systemic embolic events in a tertiary referral HCM cohort. METHODS: This study included 374 clinically diagnosed patients with HCM...

BACKGROUND: Right parasternal view (RPV) is important in assessing the severity of aortic stenosis (AS). However, the feasibility and relevance of RPV in primary care is unresolved. Moreover, information regarding the role of RPV in the evaluation of the hemodynamic progression of AS is lacking. METHODS: Consecutive patients with peak aortic valve velocity (Vmax) ≥2.5m/s were prospectively enrolled in a primary care echocardiographic laboratory. Aortic Doppler parameters were evaluated from apical view and RPV...

Estimation of right ventricular (RV) performance still remains technically challenging due to its anatomical and functional distinctiveness. The current guidelines for the echocardiographic quantification of RV function recommend using multiple indices to describe the RV in a thorough and comprehensive manner, such as RV index of myocardial performance, tricuspid annular plane systolic excursion, fractional area change, Doppler tissue imaging-derived tricuspid lateral annular systolic velocity (S'-wave), three-dimensional RV ejection fraction (3D RVEF), longitudinal strain (RVLS)/strain rate by speckle-tracking echocardiography (STE)...

The objective of this study was to investigate the usefulness of intraprocedural hemodynamic monitoring for MR evaluation during pMRV. Assessment of mitral regurgitation (MR) during percutaneous mitral valve repair (pMVR) procedure is challenging. 3D color Doppler allows exact quantification of MR, but is technically demanding. Sixty patients with moderate to severe MR (14 with structural and 46 functional MR) were included in the study. Intraprocedural pressure curves were continuously obtained in the left atrium (LA) and left ventricle (LV)...

Pericardial effusion (PEff) is defined by an increase in the physiological amount of fluid within the pericardial space. It can appear following different medical conditions, mainly related to inflammation and cardiac surgery. Cardiac tamponade is a critical condition that occurs after sudden and/or excessive accumulation of fluid in the pericardial space that restricts appropriate filling of the cardiac chambers disturbing normal hemodynamics and ultimately causing hypotension and cardiac arrest. It is, therefore, a life-threatening condition that must be diagnosed as soon as possible for correct treatment and management...

BACKGROUND: Invasive studies have shown that prevalence and severity of pulmonary hypertension (PH) in patients with sickle cell disease (SCD) tend to be overestimated if based exclusively on Doppler-derived tricuspid regurgitant velocity (TRV) as surrogate noninvasive marker with a cutoff ≥2.5 m/s. OBJECTIVES: We aimed to better define a subgroup of pediatric SCD patients who should be sent for invasive evaluation of pulmonary artery pressure (PAP) based on a modified echocardiographic PH screening protocol that implements evidence from Doppler-catheter comparative studies...

BACKGROUND: Echocardiographic right ventricular (RV) function assessment is difficult and still a gray area despite rapid advancement of imaging modalities. The aim of this study is to assess the role of echocardiographic RV outflow tract (RVOT) function in the form of RVOT fractional shortening (RVOT FS) and RVOT systolic excursion (RVOT SE) for the assessment of RV function. METHODS: We studied ninety individuals divided equally into two groups. The control group included 45 normal healthy individuals and age-matched patient group included 45 patients with RV dysfunction which was defined by tricuspid annular plane systolic excursion (TAPSE) <16 mm and RV fractional area change (RV FAC) ≤35%...

A 12-year-old spayed female miniature Poodle presented for coughing, respiratory distress, and anorexia. After thoracentesis for pleural effusion, radiography revealed an enlarged cardiac silhouette with a bulge in the area of the body of the right atrium. Echocardiography revealed an anechoic chamber-like cavity lateral to the right atrium that communicated with the right atrium through a 13 mm defect in the right atrial free wall. Contrast echocardiography and color flow Doppler were used to prove that the cavity communicated with the right atrium...

Hypertrophic cardiomyopathy (HCM) is a common autosomal dominant cardiac disease, affecting 1 in 500 people. Myosin-binding protein C3 (MyBPC3) gene mutations are the most common genetic cause of HCM. However, the prevalence of the MyBPC3 gene mutation in Chinese patients with HCM, and their echocardiographic characteristics, remain unknown. In the present study, 48 Chinese patients with HCM were sequenced to identify the MyBPC3 gene and were characterized by their clinical features using 2-dimensional echocardiography and real-time 3-dimensional echocardiography...
