Left ventricular (LV) ejection fraction (LVEF) is the most validated and commonly used echocardiographic measure of systolic function. LVEF has a unique position in cardiology having severed as selection criteria for therapeutic trials that constitute the evidence base of today's treatment recommendations. Assessment of LV systolic function by global longitudinal strain (GLS) from speckle tracking echocardiography (STE) is a sensitive and feasible method that overcomes many of the limitations of LVEF, including reproducibility issues of serial testing and detection of LV dysfunction in pathologically remodeled hearts...

BACKGROUND: Left ventricular diastolic function is an important prognostic marker in acute coronary syndrome. However, classification of the dysfunction grade using isolated echocardiographic parameters remains difficult. Therefore, it is necessary to combine multiple data in diagnostic algorithms. The purpose of this study was to evaluate the capacity of left atrial strain (LAS) components to classify left ventricular diastolic dysfunction (DD) grade. METHODS: Cross-sectional study with 109 consecutive patients admitted to the emergency room with acute coronary syndrome...

BACKGROUND: Secondary mitral regurgitation (MR) remains a challenging problem in the diagnosis and treatment of patients with heart failure. Although it is well known that secondary MR is dynamic, the impact of the severity of MR during exercise on long-term outcome has not been fully evaluated. The aim of the present study was to investigate the prognostic value of exercise stress echocardiography (ESE) in patients with secondary MR. METHODS: This prospective study included 118 consecutive patients with secondary MR and left ventricular dysfunction (mean ejection fraction at rest: 38 ± 14%) who underwent semi-supine ESE...

BACKGROUND: To detect early cardiac deterioration, a simple and stable tool is needed. Measurement of time intervals in a simple 4-chamber view using color-coded tissue Doppler imaging is a relatively new approach to assess fetal cardiac function. The aim of this study was to evaluate the applicability of this modality and to construct reference ranges for cardiac time intervals. METHODS: We performed a prospective longitudinal cohort study in healthy fetuses. We used linear mixed models to construct age-adjusted reference ranges for shortening time (St) and lengthening time (Lt) in three cardiac regions: global heart and right and left ventricular wall...

BACKGROUND: The aim of this study was to quantify the acute dynamic changes of mitral valve (MV) geometry throughout the cardiac cycle-during percutaneous MV repair with the MitraClip system by 3-dimensional transesophageal echocardiography (3D TEE). METHODS: The MV was imaged throughout the cardiac cycle (CC) before and after the MitraClip procedure using 3D TEE in 28 patients (mean age, 77 ± 8 years) with functional mitral regurgitation (FMR). Dynamic changes in the MV annulus geometry and anatomical MV orifice area (AMVOA) were quantified using a novel semi-automated software...

LV is a pressure-generating pump which endures pressure overload, while RV is a flow-generating pump intolerant of pressure overload. Therefore, RV pump function (but not RV myocardial contractility) can easily fail in face of severe pulmonary arterial hypertension (PH) because of increased afterload. Available indexes of RV function are load dependent and incapable of accurately reflecting RV myocardial contractility. Animal RV in which myocardium is damaged extensively by either soldering iron or coronary occlusion can work well without causing systemic congestion or decreased SV...

BACKGROUND: A limited number of studies have investigated the effects of radiofrequency catheter ablation (RFCA) on left ventricular (LV) function and the left atrial (LA) size in patients with atrial fibrillation (AF). The purpose of this study was to conduct a comprehensive assessment of LV function in patients with AF with preserved left ventricular ejection fraction (LVEF) before and after RFCA. METHOD: A total of 30 consecutive patients with no recurrences after RFCA for persistent AF (age, 57...

Substantial or complete myocardial recovery occurs in many patients with heart failure (HF). HF patients with myocardial recovery or recovered left ventricular (LV) ejection fraction (EF; HFrecEF) are a distinct population of HF patients with different underlying etiologies, comorbidities, response to therapies, and outcomes compared with HF patients with persistent reduced or preserved EF. Improvement in LVEF has been systematically linked to improved quality of life, and lower rehospitalization rates and mortality...

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...

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)...

BACKGROUND: Adjuvant trastuzumab improved overall survival and reduced the risk for disease recurrence in women with breast cancers, because of its potential cardiotoxicity, careful monitoring of left ventricular (LV) function during treatment is required. METHODS: This study investigates, whether myocardial strain imaging and level of N-terminal pro-brain natriuretic peptide (NT-pro BNP) could predict subsequent reduction in LVEF in breast cancer patients received adjuvant trastuzumab...
