OBJECTIVES: We assessed to what extent arterial properties measured at baseline and follow-up predict longitudinal alterations in echocardiographic indexes reflecting left ventricular (LV) structure and function. BACKGROUND: Serial imaging studies are needed to clarify the relation of changes in LV structure and function to arterial stiffness. METHODS: In 607 participants (50.7% women; mean age 50.7 years), using echocardiography and Doppler imaging, we measured LV dimensions, transmitral blood flow, and mitral annular tissue velocities at baseline and after 4...

OBJECTIVES: This study sought to identify Doppler parameters useful for the assessment of left ventricular filling pressure (LVFP) in patients with mitral annular calcification (MAC) and to develop and validate a decision algorithm for assessing LVFP in such patients. BACKGROUND: Predicting LVFP in the presence of MAC is problematic. METHODS: Prospectively, 50 patients with MAC (mean 72 ± 11 years of age) underwent a complete Doppler echocardiographic study and right or left heart catheterization...

Aims: Heart failure with preserved ejection fraction (HFpEF) is a complex syndrome with various phenotypes and outcomes. The prognostic relevance of echocardiography and the E/e' ratio has previously been reported. We sought to study in addition, the value of estimated pulmonary pressure and left atrial size for diagnosing and determining a prognosis for HFpEF-patients in a prospective multi-centric cohort. Methods and results: Patients with an acute-HF event accompanied with NT-proBNP >300 pg/mL (BNP >100 pg/mL) and LVEF >45% were included (n = 237) and clinically reassessed using echo-Doppler after 4-8 weeks of HF treatment as part of the prospective KaRen HFpEF study...

BACKGROUND: Doppler echocardiography is ideally suited for assessment of diastolic function, being widely available, non-invasive, and less expensive than other techniques. However, data regarding age- and gender-matched reference values of right ventricular diastolic function are limited. This study aims to explore the physiologic variations of right ventricle (RV) diastolic function in a large cohort of healthy adults, and to investigate clinical and echocardiographic correlates. METHODS: From June 2007 to February 2014, 1168 healthy Caucasian subjects [mean age 45...

Right heart dysfunction has been found to be a strong prognostic factor predicting adverse outcome in various cardiopulmonary diseases. Conventional echocardiographic measurements can be limited by geometrical assumptions and impaired reproducibility. Speckle tracking-derived strain provides a robust quantification of right ventricular function. It explicitly evaluates myocardial deformation, as opposed to tissue Doppler-derived strain, which is computed from tissue velocity gradients. Right ventricular longitudinal strain provides a sensitive tool for detecting right ventricular dysfunction, even at subclinical levels...

To evaluate the right ventricular (RV) function in relation to that of the left ventricle (LV) in patients with dilated cardiomyopathy (DCM). Echocardiographic examination was done using tissue Doppler imaging (TDI) and two-dimensional speckle tracking echocardiography (2D-STE) for 32 pediatric patients with DCM comparing them to another 32 normal matched controls. The global longitudinal strain (GLS) derived from 2D-STE was used to reflect the LV systolic function. Tricuspid annular plan systolic excursion (TAPSE) and the following RV TDI derived indexes: peak systolic velocity (S'), peak early diastolic velocity E', peak late diastolic velocity A', isovolumic acceleration (IVA) and myocardial performance index (MPI) were measured...

OBJECTIVE: Cardiac resynchronization therapy (CRT) has been shown to induce a structural and electrical remodeling; the data on whether left ventricle (LV) reverse remodeling is associated with restitution of intrinsic contraction pattern are unknown. In this study, we investigated the presence of improvement in left ventricular intrinsic dyssynchrony in patients with CRT. METHODS: A total of 45 CRT recipients were prospectively studied. Dyssynchrony indexes including interventricular mechanical delay (IVMD) and tissue Doppler velocity opposing-wall delay (OWD) as well as QRS duration on 12-lead surface electrocardiogram were recorded before CRT device implantation...

BACKGROUND: High sensitive troponin T (hsTnT), a marker of myocardial injury, appears to be a promising diagnostic tool in patients with congenital heart disease. However, little is known about its distribution among adults with systemic right ventricle (sRV). We aimed to assess the distribution of hsTnT concentrations in patients with congenitally corrected transposition of the great arteries (ccTGA) and to evaluate its relationship with sRV function and NT-proBNP. METHODS: A cross-sectional study of adults with ccTGA was conducted...

Sonographic cardiac evaluation of newborns with suspected aortic coarctation (AoC) should tend to demonstrate a good phasic and pulsatile flow and the absence of pressure gradient along a normally conformed aortic arch from the modified left parasternal and suprasternal echocardiographic views; these findings, however, may not necessarily rule out a more distal coarctation in the descending aorta. For this reason, the sonographic exam of newborns with suspected AoC should always include a Doppler evaluation of abdominal aortic blood flow from the subcostal view...

BACKGROUND: Noninvasive echocardiographic tissue Doppler assessment (E/e') in response to exercise or pharmacological intervention has been proposed as a useful parameter to assess left ventricular (LV) filling pressure (LVFP) and LV diastolic dysfunction. However, the evidence for it is not well summarized. METHODS AND RESULTS: Clinical studies that evaluated invasive LVFP changes in response to exercise/other interventions and echocardiographic E/e' were identified from PubMed, Scopus, Embase, and Cochrane Library databases...

Accurate evaluation of trans-aortic valvular pressure gradients is challenging in cases where dual mechanical aortic and mitral valve prostheses are present. Non-invasive Doppler echocardiographic imaging has its limitations due to multiple geometric assumptions. Invasive measurement of trans-valvular gradients with cardiac catheterization can provide further information in patients with two mechanical valves, where simultaneous pressure measurements in the left ventricle and ascending aorta must be obtained...

BACKGROUND: Subclinical left ventricular (LV) diastolic dysfunction in type 2 diabetes (T2D) is a common finding and represents an early sign of diabetic cardiomyopathy. However, the relationship between LV diastolic dysfunction and the incident T2D has not been previously studied. METHODS: A total of 1817 non-diabetic participants (mean age, 54 years; 48% men) from the Korean Genome and Epidemiology Study who were free of cardiovascular disease were studied. LV structure and function were assessed by conventional echocardiography and tissue Doppler imaging...

BACKGROUND: Heart failure with preserved ejection fraction is closely associated with diastolic dysfunction and related to obesity and female sex. We investigated whether adiponectin, an adipocyte-secreted protein hormone with cardioprotective effects, was associated with indices of diastolic dysfunction, and whether the association was sex dependent. METHODS: We conducted a cross-sectional study on 1165 women and 896 men without diabetes. We stratified the multivariable adjusted logistic regression analyses and the fractional polynomial regression analyses according to sex, with echocardiographic markers of diastolic dysfunction as dependent variables, and adiponectin as the independent variable of interest...

This literature review is devoted to noninvasive evaluation of the left ventricular (LV) diastolic function by echocardiography with special stress on existing problems of detection of LV dysfunction by Doppler echocardiography of transmitral blood flow. Basing on existent algorithms one often cannot clearly judge whether LV dysfunction is present even when such methods are used as assessment of blood flow in pulmonary veins, transmitral blood flow during the Valsalva maneuver, etc. The review also contains discussion and analysis of newly suggested Doppler echocardiography based algorithms of detection of LV diastolic dysfunction and estimation of its severity (two-dimensional deformation of left atrial walls, three-dimensional echocardiography and three-dimensional deformation of the left ventricle)...

Pulmonary hypertension (pH) is a frequent and severe phenomenon in heartworm disease (Dirofilaria immitis). There is a lack of studies assessing the evolution of the proliferative endarteritis and pH caused by D. immitis after the death of the parasites, so this study evaluated the influence that the elimination of the worms exerts over the pulmonary pressure and therefore evolution of the endarteritis, through the evaluation of the Right Pulmonary Artery Distensibility (RPAD) Index and other echocardiographic measurements in 2D mode, M-mode and Doppler echocardiography in 34 dogs naturally infected by D...
