BACKGROUND: Left atrial analysis is employed in diastolic assessment with left atrial volume index (LAVI) incorporated in the 2016 ASE/EACVI diastology guideline algorithm. LAVI has sub-optimal correlation with invasive left ventricular filling pressure (LVFP) and incorporation of left atrial reservoir strain (LASr) may improve diastolic assessment. METHODS: A cross-sectional prospective study of 139 patients was undertaken with all patients undergoing transthoracic echocardiography immediately prior to cardiac catheterization with invasive evaluation of LVFP...

OBJECTIVE: Although American and European consensus statements advocate using the ratio of the transmitral E velocity and tissue Doppler early diastolic mitral annular velocity (E/e') in the assessment of left-sided heart filling pressures, recent reports have questioned the reliability of this ratio to predict left atrial pressures in a variety of disease states. The authors hypothesized that there is a clinically significant correlation between E/e' and pulmonary capillary wedge pressure (PCWP) in patients with severe aortic stenosis...

Diastolic dysfunction is a known cause of mortality in adults with sickle cell disease (SCD). Left atrial function (LAf) and strain (LAS) are novel echocardiographic parameters to assess early diastolic dysfunction, which have not been assessed in pediatric SCD. Through a retrospective single-center study, we describe echocardiographic parameters of diastology in children with SCD and evaluate their relationship with clinical variables including anemia and blood pressure. Baseline clinical data, 24-hour ambulatory blood pressure monitoring data and echocardiography results were collected...

BACKGROUND: The utility of Doppler velocities across the patent foramen ovale (PFO) to estimate left ventricular (LV) filling pressure is not well known. METHODS: The best cut-off value of peak interatrial septal velocity across a transeptal puncture site measured by transesophageal echocardiography for estimating high mean left atrial (LA) pressure (≥ 15 mmHg) was determined in 17 patients. This cut-off value was subsequently applied to 67 patients with a PFO undergoing transthoracic echocardiography (TTE) for assessing the value of PFO velocity in determining LV filling pressure...

BACKGROUND: Limited data exist on the differential ability of variables on transthoracic echocardiogram (TTE) to predict heart failure (HF) readmission across the spectrum of left ventricular (LV) systolic function. METHODS: We linked 15 years of TTE report data (1/6/2003-5/3/2018) at Beth Israel Deaconess Medical Center to complete Medicare claims. In those with recent HF, we evaluated the relationship between variables on baseline TTE and HF readmission, stratified by LVEF...

BACKGROUND: Currently risk stratification of moderate aortic stenosis (AS) is still incipient. The aim of this study was to identify prognostic factors in patients with moderate AS. METHODS: The prognosis of patients with moderate AS (1 < aortic valve area ≤ 1.5 cm2 ) stratified by left ventricular ejection fraction (LVEF; 50%), stroke volume index (SVI; 35 mL/m2 ), and elevated E/e' ratio (average, 14) was compared with that of the age- and sex-matched general population...

BACKGROUND: Abnormal invasive hemodynamics after transcatheter aortic valve replacement (TAVR) is associated with poor survival; however, the mechanism is unknown. HYPOTHESIS: Diastolic dysfunction will modify the association between invasive hemodynamics postTAVR and mortality. METHODS: Patients with echocardiographic assessment of diastolic function and postTAVR invasive hemodynamic assessment were eligible for the present analysis. Diastology was classified as normal or abnormal (Stages 1 to 3)...

To help standardize the assessment of diastolic dysfunction in the United States, the American Society of Echocardiography (ASE) released criteria for the assessment of diastology in patients with normal and abnormal ejection fraction. As heart failure with preserved ejection fraction (HFpEF) is a leading cause of morbidity and mortality in cardiac patients, it is imperative to assess diastology appropriately. Echocardiography is the mainstay in the assessment of diastolic function; with the new ASE guidelines, diagnosis is simplified especially in patients that have preserved baseline ejection fraction...

Left ventricular (LV) diastolic function can be most conveniently assessed by echocardiography which provides reliable assessments of LV structure and function. Most patients with structural heart disease have variable degrees of myocardial dysfunction. LV structural changes as pathologic hypertrophy and systolic functional abnormalities as depressed LV long-axis systolic function are associated with diastolic dysfunction. The recognition of structural abnormalities and abnormal LV long-axis function as indices of diastolic dysfunction is an important difference between 2016 and 2009 guidelines...

The 2016 American Society of Echocardiography/European Association of Echocardiography (ASE/EACVI) guidelines on the assessment of diastolic function sought to simplify the assessment of diastolic function by recommending a streamlined, stepped approach with a focus on four key variables. Haemodynamic validation using simultaneous cardiac catheterisation and echocardiographic assessment of diastolic function have shown robust prediction of left ventricular filling pressure (LVFP) using the streamlined 2016 algorithms, with favourable comparisons to the 2009 guidelines...

BACKGROUND: Right ventricular (RV) function is prognostically relevant in heart failure with preserved ejection fraction (HFpEF) but data on profound assessment of RV and right atrial (RA) interaction in HFpEF are lacking. The current study characterizes RV and RA interaction using invasive pressure-volume-loop analysis and cardiac magnetic resonance imaging (CMR) data. METHODS AND RESULTS: We performed CMR and myocardial feature-tracking in 24 HFpEF patients and 12 patients without HFpEF...

Diastolic filling of the heart is a complex sequence of multiple inter-related events consisting of processes such as ventricular relaxation, erectile coronary effect, visco-elastic forces of the myocardium, ventricular interaction, myocardial stress strain relationships, pericardial restraint, passive filling, and atrial contraction. However, in order to understand diastolic filling from a clinical aspect, a simplified foundation can be used which divides the cardiac cycle into contraction, relaxation, passive filling, and filling at atrial contraction...

Aims: Myocardial oxygenation is impaired in hypertrophic cardiomyopathy (HCM) patients with left ventricular hypertrophy (LVH), and possibly also in HCM gene carriers without LVH. Whether these oxygenation changes are also associated with abnormalities in diastolic function or left ventricular (LV) strain are unknown. Methods and results: We evaluated 60 subjects: 20 MYBPC3 gene positive patients with LVH (G+LVH+), 18 MYBPC3 gene positive without LVH (G+LVH-), 11 gene negative siblings (G-), and 11 normal controls (NC)...

Heart failure with preserved ejection fraction (HFpEF) looms as a major public heart challenge with increasing prevalence due to an ageing population. Diagnosis can be challenging due to non-specific symptomatology, low natriuretic peptide levels and equivocal diastology on resting echocardiography. Diastolic stress echocardiography represents a non-invasive option to refining the diagnosis in this subset of patients. Diastolic responses to exercise are most commonly measured with a non-invasive measure of left ventricular filling pressures (LVFP) estimated by the ratio of the early mitral inflow wave to early diastolic tissue velocity (E/e' ratio)...

Transient elevation of LV diastolic pressure above LA pressure can occur in severe aortic regurgitation in the diastasis phase. Mitral E wave reversal in such a situation could serve as non-invasive evidence of elevated left ventricular diastolic pressures, thereby guiding therapeutic decision making.

BACKGROUND: Left ventricular (LV) hypertrophy, a key process in human cardiac disease, results from cellular (hypertrophy) and extracellular matrix expansion (interstitial fibrosis). OBJECTIVES: This study sought to investigate whether human myocardial interstitial fibrosis in aortic stenosis (AS) is plastic and can regress. METHODS: Patients with symptomatic, severe AS (n = 181; aortic valve area index 0.4 ± 0.1 cm2 /m2 ) were assessed pre-aortic valve replacement (AVR) by echocardiography (AS severity, diastology), cardiovascular magnetic resonance (CMR) (for volumes, function, and focal or diffuse fibrosis), biomarkers (N-terminal pro-B-type natriuretic peptide and high-sensitivity troponin T), and the 6-min walk test...

OBJECTIVE: For chronic heart failure (CHF), more emphasis has been placed on evaluation of systolic as opposed to diastolic function. Within the study of diastology, measurements of left ventricular (LV) longitudinal myocardial relaxation have the most validation.

AIMS: High-intensity interval training (HIIT) improves peak oxygen uptake and left ventricular diastology in patients with heart failure with preserved ejection fraction (HFpEF). However, its effects on myocardial strain in HFpEF remain unknown. We explored the effects of HIIT and moderate-intensity aerobic continuous training (MI-ACT) on left and right ventricular strain parameters in patients with HFpEF. Furthermore, we explored their relationship with peak oxygen uptake (VO2peak )...
