BACKGROUND The aim of the study was to investigate the relationship between the ejection fraction (EF) and the mitral annular systolic velocity (Sm) in patients with preserved left ventricular systolic function (EF>55%). The study task was to evaluate whether the assessment of Sm(avg) can be used as an alternative to the Simpson's method in assessment of the EF. The expected benefit was that Sm...

Background We have previously shown that a larger indexed enddiastolic volume (EDVi) of a functional single ventricle as determined by cardiac magnetic resonance (CMR) is an independent predictor of death and heart transplant late after the Fontan operation. Other reports have suggested that decreased ventricular strain and ejection fraction (EF) are associated with poor outcomes. The objective...

Approximately half of patients with a diagnosis of heart failure have a normal left ventricular (LV) ejection fraction (EF) without valve disease which is defined as diastolic heart failure (DHF), because it is attributed to LV diastolic dysfunction.[2] Studies examining prevalence of diastolic heart failure in hospitalized patients or in patients undergoing outpatient diag‐ nostic screening an...

Planar equilibrium radionuclide angiography (ERNA) is used to determine global and regional measures of ventricular function (primarily left ventricular [LV] function) at rest and/or during exercise stress or pharmacologic intervention. These measures of ventricular function may include evaluations of ventricular wall motion, ejection fraction (EF), and other parameters of systolic and diastoli...

Background Assessment of regional ventricular deformation is more sensitive than ejection fraction (EF) for detecting myocardial dysfunction. We sought to compare a local sinewave modelling (SinMod) method with the more established harmonic phase analysis (HARP) technique, for assessment of Lagrangian left ventricular (LV) peak systolic circumferential strain (εcc) from tagged cardiovascular ma...

Methods HFPEF was defined as serum NT-proBNP levels >220 pg/ml, E/e by echocardiography ≥8, signs or symptoms of heart failure and preserved left ventricular ejection fraction (EF≥50%). 58 HFPEF patients and 34 controls were prospectively evaluated. All patients underwent right heart catheterization. CMR studies included the assessment of cardiac function and dimensions by standard cine sequenc...

BACKGROUND In patients with left ventricular hypertrophy (LVH), LV midwall fractional shortening (FS) is used as a measure of LV systolic performance that is more physiologically appropriate than conventional FS. For evaluation of LV volume and ejection fraction (EF), 2-dimensional (2D) echocardiography is more accurate than M-mode echocardiography. The purpose of this study was to assess systo...

AIMS To determine the prevalence of right ventricular (RV) dysfunction in patients with preserved left ventricular (LV) ejection fraction (EF) heart failure (HF) and to compare RV function between patients with preserved EF HF and those with reduced EF HF. METHODS AND RESULTS Hundred patients (72 +/- 14 years, 59% male) with HF were prospectively enrolled. Fifty-one had preserved EF HF (LVEF ...

Background Global measures of heart function, e.g. LV mass (LVM) and ejection fraction (EF), are usually measured from cine CMR images. On the other hand, regional measures of myocardial contractility are obtained from tagged images. The acquisition of both datasets consumes most of the CMR exam duration. In this study, we present a method for estimating measures of global heart function from t...
