Aims: It remains unclear whether surgical or transcatheter mitral valve repair for secondary mitral regurgitation (MR) in patients with non-ischaemic cardiomyopathy reverse the underlying left ventricular (LV) pathophysiology. We hypothesized that mitral valve repair improves LV systolic function and forward flow and induces LV reverse remodelling in this group of patients. Methods and results: Seventy-six patients (65 ± 14 years old, 43% male) with non-ischaemic cardiomyopathy and moderate to severe chronic secondary MR treated successfully with transcatheter or surgical mitral valve repair were evaluated...

BACKGROUND: E/e' is clinically useful for the noninvasive assessment of left ventricular (LV) filling pressure. However, its use in some conditions is controversial, and angle dependence of the Doppler measurement and preload dependence of mitral e' in nondilated hearts represent major problems. The ratio of early filling rate derived from the time derivative of LV volume to early diastolic strain rate (FRe/SRe), similar to E/e', by three-dimensional (3D) speckle-tracking echocardiography has the potential to address such limitations...

BACKGROUND: In patients who have undergone arterial switch operation (ASO) for d-transposition of the great arteries a gothic aortic arch (GA) morphology has been found and it has been associated with abnormal aortic bio-elastic properties. HYPOTHESIS: GA is frequent in ASO patients and may have an impact on cardiac mechanics. Our study aims were to assess 1- the occurrence of GA in a large sample of patients after ASO; 2- the association between GA and aortic bio-elastic properties; and 3- the impact of GA on left ventricular (LV) function using speckle tracking echocardiography (STE)...

AIMS: Left ventricular mechanical dyssynchrony has been described in heart failure with preserved ejection fraction (HFpEF), but its prognostic significance is not known. METHODS AND RESULTS: Of 3445 patients with HFpEF enrolled in the Treatment of Preserved Cardiac Function Heart Failure with an Aldosterone Antagonist (TOPCAT) trial, dyssynchrony analysis was performed on 424 patients (12%) by multiple speckle tracking echocardiography strain-based criteria. The primary dyssynchrony analysis was the standard deviation of the time to peak longitudinal strain (SD T2P LS)...

BACKGROUND: The benefit of revascularization for functional recovery depends on the presence of viable myocardial tissue. OBJECTIVE: Myocardial deformation imaging allows determination of myocardial viability. METHODS: In a first approach, we assessed the optimal cutoff value to determine preserved viability by layer-specific echocardiographic myocardial deformation imaging at rest and low-dose dobutamine (DSE) echocardiography: regional endocardial circumferential strain (eCS) <-19% at rest was as accurate as eCS at DSE...

Diastolic wall strain (DWS) is based on the linear elastic theory, according to which decreased wall thinning during diastole reflects reduced left ventricular compliance and thus increased diastolic stiffness. Increased diastolic stiffness as assessed by DWS is associated with a worse prognosis in patients who have heart failure (HF) with preserved ejection fraction. However, there are no data about the prognostic value of DWS derived by M-mode echocardiography in patients at risk for HF. We retrospectively enrolled 1829 consecutive patients without prior HF who were hospitalized for cardiovascular (CV) diseases in our hospital between 2005 and 2012...

BACKGROUND: Translational failure for cardiovascular disease is a substantial problem involving both high research costs and an ongoing lack of novel treatment modalities. Despite the progress already made, cell therapy for chronic heart failure in the clinical setting is still hampered by poor translation. We used a murine model of chronic ischemia/reperfusion injury to examine the effect of minimally invasive application of cardiac progenitor cells (CPC) in cardiac remodeling and to improve clinical translation...

Cardiac allograft rejection (CAR) may occur after transplantation and remains silent, until hemodynamic deterioration takes place. Endomyocardial biopsy (EMB) is applied to early detect CAR. Although, flexible bioptoms have decreased the incidence of lethal complications, EMB remains an invasive procedure carrying risk of tamponade and permanent heart block. Therefore, a new non-invasive approach is needed. Areas covered: AlloMap molecular expression testing and graft-derived cell-free DNA (GcfDNA) test can be used as blood indices of acute and chronic CAR, respectively...

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...

Left ventricular hypertrophy (LVH) develops in response to a variety of physical, genetic, and biochemical stimuli and represents the early stage of ventricular remodeling. In patients with LVH, subclinical left ventricular (LV) dysfunction despite normal ejection fraction (EF) may be present before the onset of symptoms, which portends a dismal prognosis. Strain measurement with two-dimensional speckle tracking echocardiography (STE) represents a highly reproducible and accurate alternative to LVEF determination...

Imaging studies have shown that pulmonary hypertension (PH) is associated with inhomogenous right ventricular (RV) regional contraction, or dyssynchrony, and that this is of prognostic relevance. This study aimed at the identification and functional significance of RV dyssynchrony in borderline PH defined by a mean pulmonary artery pressure between (mPAP) 20 and 25 mmHg. RV dyssynchrony was measured by 2-dimensional speckle tracking echocardiography in 17 patients with pulmonary arterial hypertension (PAH), 13 patients with borderline PH and 14 controls...

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...

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...
