doppler echo to measure lv filling pressures

Frank Lloyd Dini, Gani Bajraktari, Cornelia Zara, Nicola Mumoli, Gian Marco Rosa
Chronic heart failure (HF) is an important public health problem and is associated with high morbidity, high mortality, and considerable healthcare costs. More than 90% of hospitalizations due to worsening HF result from elevations of left ventricular (LV) filling pressures and fluid overload, which are often accompanied by the increased synthesis and secretion of natriuretic peptides (NPs). Furthermore, persistently abnormal LV filling pressures and a rise in NP circulating levels are well known indicators of poor prognosis...

INTRODUCTION: This study evaluates the agreement between emergency physician (EP) assessment of diastolic dysfunction (DD) by a simplified approach using average peak mitral excursion velocity (e'A ) and an independent cardiologist's diagnosis of DD by estimating left atrial (LA) pressure using American Society of Echocardiography (ASE) guidelines. METHODS: This was a secondary analysis of 48 limited bedside echocardiograms (LBE) performed as a part of a research study of patients presenting to the Emergency Department (ED) with elevated blood pressure but without decompensated heart failure...

Aims: Left ventricular outflow (LVOT) obstruction in patients with hypertrophic cardiomyopathy (HCM) is dynamic and sensitive to many variables that affect left ventricular preload, afterload, and contractility. The haemodynamic effect of normal respiration on LVOT obstruction has not been described. Methods and results: We examined 20 patients with HCM who were noted to have phasic respiratory variation of LVOT obstruction on initial transthoracic 2D echocardiogram and Doppler examination...

BACKGROUND: Obesity contributes to left ventricular (LV) diastolic dysfunction (LVDD) and may lead to diastolic heart failure. Weight loss (WL) after bariatric surgery (BS) may influence LV morphology and function. Using echocardiography, this study assessed the effect of WL on LV diastolic function (LVDF) and LV and left atrium (LA) morphology 6 months after BS in young women with morbid obesity. METHODS: Echocardiography was performed in 60 women with body mass index ≥ 40 kg/m², aged 37...

The ability of echocardiography (echo)/Doppler to predict elevated left ventricular (LV) end-diastolic pressure (EDP) specifically among patients with pulmonary hypertension is not well defined. This was a retrospective analysis of 161 patients referred to a specialized pulmonary hypertension clinic. A model based on an American Society of Echocardiography (ASE)/European Association of Echocardiography (EAE) joint statement was evaluated, and a new model was developed using univariate linear regression and multivariable logistic regression for potentially better prediction of elevated LVEDP...

BACKGROUND: Diastolic dysfunction is common and associated with higher mortality in the end-stage renal disease (ESRD) population. E/E', a measure derived from tissue Doppler imaging (TDI), is a correlate of left ventricular (LV) filling pressures. E/E' may be viewed as a confirmatory marker of diastolic dysfunction, but it is not routinely used to quantify diastolic dysfunction. Whether E/E' is associated with N-terminal brain natriuretic peptide (NT-proBNP) or high sensitivity troponin T (hs-TnT) in this population is not known...

BACKGROUND: While speckle imaging has been shown to predict outcome in patients with heart failure (HF), it remains unclear whether speckle strain predicts outcome in patients with HF with preserved ejection fraction (HFPEF). METHODS: Four hundred twenty patients with HF by Framingham criteria and either: left ventricular (LV) EF <50%, or elevated LV filling pressure by comprehensive echo Doppler study in the setting of left ventricular ejection fraction (LVEF) ≥50%, were enrolled...

AIMS: The non-invasive estimation of left ventricular filling pressures (LVFPs) represents a main goal in the clinical setting. Current recommendations encourage the use of pulsed-wave Tissue Doppler for calculating the ratio between the preload-dependent transmitral E velocity and the average of septal and lateral early diastolic velocities (e') of the mitral annulus. Despite its wide use, real utility of the E/e' ratio has been recently challenged in patients with either very advanced heart failure or preserved left ventricular (LV) ejection fraction...

BACKGROUND: The plasma B-type natriuretic peptide (BNP) level has been shown to be increased in patients with chronic atrial fibrillation (AF) independent of left ventricular ejection fraction (LVEF). The purpose of this study is to evaluate the relationship between the plasma BNP level and heart rate variation in patients with AF. HYPOTHESIS: The plasma BNP level is associated with heart rate variation in patients with AF. METHODS: A total of 102 patients with AF and preserved LVEF were included from 2 hospitals...

BACKGROUND: The left ventricular end-diastolic pressure-volume relationship (LV-EDPVR) is a measure of LV distensibility, conveying the size the LV will assume at a given LV end-diastolic pressure (LV-EDP). Measurement of LV-EDPVR requires invasive testing with specialized equipment. Echocardiography can be used to measure LV end-diastolic volume (EDV) and to grossly estimate LV-EDP noninvasively. We therefore hypothesized that categorization of patients based on these parameters to create an estimate of the end-diastolic pressure-volume loop position (EDPVE) could predict congestive heart failure (CHF) prognosis...

BACKGROUND: The aim of this study was to prospectively examine echocardiographic parameters that correlate and predict functional capacity assessed by 6 min walk test (6-MWT) in patients with heart failure (HF), irrespective of ejection fraction (EF). METHODS: In 147 HF patients (mean age 61 ± 11 years, 50.3% male), a 6-MWT and an echo-Doppler study were performed in the same day. Global LV dyssynchrony was indirectly assessed by total isovolumic time - t-IVT [in s/min; calculated as: 60 - (total ejection time + total filling time)], and Tei index (t-IVT/ejection time)...

OBJECTIVE: Assessment of plasma matrix metalloproteinase-9 (MMP-9) and Doppler markers of increased left ventricular (LV) filling pressure may be added to risk stratify patients with ischemic cardiomyopathy (IC). Therefore, we aimed at investigating the value of plasma MMP-9 and restrictive filling pattern (RFP) in IC patients. METHODS: Eighty-eight consecutive patients hospitalized for heart failure (LV ejection fraction ≤ 40%) due to IC were enrolled. A complete M-mode and two-dimensional echo-Doppler examination were performed...

AIMS: In aortic stenosis (AS), both reduced systemic arterial compliance and increased valvular load have been shown to contribute to impaired left ventricular (LV) function. However, the relationship between LV function and aortic stiffness has not yet been investigated. We aimed to assess the relationship between aortic stiffness and LV global longitudinal strain (GLS), LV filling pressures (E/E') and B-type natriuretic peptide (BNP) in AS. METHODS AND RESULTS: A comprehensive echocardiogram was performed in 48 consecutive patients with severe AS (<0...

OBJECTIVES: this study evaluated early diastolic filling dynamics using a semiautomated objective analysis of filling velocities obtained from color M-mode echocardiography. BACKGROUND: diastolic function can be evaluated from color M-mode echocardiography by measuring the early diastolic flow propagation velocity (Vp) from the slope of a single linear approximation of an isovelocity contour. However, this method has limitations and may not accurately represent diastolic filling...

Diastolic Heart failure (DHF) is the major cause of morbidity and mortality all over the world. It is responsible for more than 50% of the heart failure cases. New onset of symptomatic DHF is a lethal disease with a 5-yr mortality of approximately 50%. DHF is also referred to as heart failure (HF) with normal left ventricular ejection fraction (LVEF)-HFNLVEF. The diagnosis of DHF requires the following criteria: (i) signs and symptoms of heart failure (ii) normal or mildly abnormal systolic left ventricular (LV) function (iii) evidence of LV diastolic dysfunction...

We investigated the impact of lowering blood pressure (BP) with azelnidipine, a newly developed calcium channel blocker, generation on the left ventricular (LV) diastolic function and LV filling pressure by assessing non-invasive indices derived from echo Doppler study. This study evaluated 232 hypertensive patients with diastolic dysfunction. This study had two groups: (1) in which azelnidipine was administered to patients as a first-line therapy, and (2) in which amlodipine was converted to azelnidipine. Early diastolic mitral annulus velocity (e', cm s(-1)), the ratio of peak E velocity to e' velocity (E/e' ratio) and level of brain natriuretic peptide (BNP) were measured before and, an average of, 8 months after azelnidipine treatment...
