BACKGROUND: Lactate has been recognised as a prognostic factor in several critical conditions. Veno-Venous Extracorporeal Membrane Oxygenation (VV-ECMO) is a well-established therapy in patients with Acute Respiratory Disease Syndrome (ARDS) unresponsive to conventional therapy and echocardiography pre ECMO initiation has been recently reported to help in risk stratifying these patients. METHODS: We assessed whether the detection of hyperlactataemia could be associated with the presence of left ventricle (LV) or right ventricle (RV) dysfunction in 121 consecutive patients with refractory ARDS...

BACKGROUND: Right ventricular (RV) function has recently gained attention as a prognostic predictor of outcome even in patients who have left-sided heart failure. Since several conventional echocardiographic parameters of RV systolic function have been proposed, our aim was to determine if any of these parameters (tricuspid annular plane systolic excursion: TAPSE, tissue Doppler derived systolic tricuspid annular motion velocity: S', fractional area change: FAC) are associated with outcome in advanced heart failure patients with dilated cardiomyopathy (DCM)...

BACKGROUND: Right ventricular (RV) dysfunction is a major determinant of outcomes in patients with pulmonary arterial hypertension (PAH), although the optimal measure of RV function is poorly defined. We evaluated the utility of RV free-wall speckle tracking strain as an assessment tool for RV function in patients with PAH who are already under specific treatment compared with conventional echocardiographic parameters and investigated the relationship of RV free-wall strain with clinical hemodynamic parameters of RV performance...

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...

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: We sought to investigate a correlation between serum testosterone levels and graft function early after heart transplantation. METHODS: In a cross-sectional study we measured serum testosterone levels 4 weeks after heart transplantation in 49 consecutive male recipients. Echocardiography was done to evaluate graft function. Low serum testosterone was defined as <11 nmol/L. RESULTS: Low serum testosterone was present in 21 (43%) recipients (Group A), and 28 (57%) had normal testosterone levels (Group B)...

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...

BACKGROUND: Studies evaluating right ventricular (RV) structural and functional abnormalities in feline hypertrophic cardiomyopathy (HCM) are limited. HYPOTHESIS: Right ventricular structural and functional abnormalities are present in cats with HCM and are associated with clinical severity. ANIMALS: Eighty-one client-owned cats. METHODS: Retrospective 2-dimensional (2D) echocardiographic study. Right atrial diameter (RAD), RV free wall thickness (RVFWd), RV internal dimension (RVIDd), RV fractional area change (FAC), and tricuspid annular plane systolic excursion (TAPSE) were measured in control cats (n = 26), cats with subclinical HCM (subclinical HCM; n = 31), and cats with HCM and congestive heart failure (HCM + CHF; n = 24)...

RATIONALE: Patients with scleroderma associated pulmonary arterial hypertension (SSc-PAH) continue to have an unacceptably high mortality despite the progress achieved with pulmonary arterial vasodilator therapies. OBJECTIVES: We sought to determine whether SSc-PAH is a clinically distinct pulmonary vascular disease phenotype when compared to IPAH, based on the progression of echocardiographic right ventricular (RV) dysfunction. METHODS: Retrospective analysis of echocardiographic data in 13 SSc-PAH and 11 IPAH patients was used to delineate the progression of RV dysfunction during single or combination pulmonary arterial vasodilator therapy...

BACKGROUNDS: Pulmonary arterial hypertension (PAH) was previously considered an illness that affects mostly the young, but now it is also increasingly recognized in the elderly. The aim of this study was to compare the features of elderly versus younger patients diagnosed with PAH, and to define the prognostic factors which affect their long-term survival. METHODS: In this prospective, single center study, the clinical, echocardiographic, hemodynamic characteristics, and the outcomes of younger (18-65 years) and elderly (≥ 65 years) patients with definitive diagnosis of precapillary PAH were compared...

BACKGROUND: There is today no established approach to estimate right ventricular ejection fraction (RVEF) using 2D transthoracic echocardiography (TTE). The aim of this study was to evaluate a new method for RVEF calculations using 2D TTE and compare the results with cardiac magnetic resonance (CMR) imaging and tricuspid annular plane systolic excursion (TAPSE). METHODS: A total of 37 subjects, 25 retrospectively included patients and twelve healthy volunteers, were included to give a wide range of RVEF...

INTRODUCTION: Right ventricular dysfunction is associated with numerous smoking-related illnesses including chronic obstructive pulmonary disease (COPD) where it is present even in absence of pulmonary hypertension. It is unknown if exposure to cigarette smoke has direct effects on RV function and cardiac fibroblast proliferation or collagen synthesis. In this study, we evaluated cardiac function and fibrosis in mice exposed to cigarette smoke (CS) and determined mechanisms of smoke-induced changes in cardiac fibroblast signaling and fibrosis...

BACKGROUND: Echocardiography (echo)-based linear fractional shortening (FS) is widely used to assess left ventricular dysfunction (LVdys ), but has not been systematically tested for right ventricular dysfunction (RVdys ). METHODS: The population comprised LVdys patients with and without RVdys (EF<50%) on cardiac MRI (CMR): Echo included standard RV indices (fractional area change [FAC], TAPSE, S', and FS in parasternal long-axis (RV outflow tract [RVOT ]) and apical four-chamber views (width [RVWD ], length [RVLG ])...

BACKGROUND: Atrioventricular plane displacement (AVPD) is an indicator for systolic and diastolic function and accounts for 60% of the left ventricular, and 80% of the right ventricular stroke volume. AVPD is commonly measured clinically in echocardiography as mitral and tricuspid annular plane systolic excursion (MAPSE and TAPSE), but has not been applied widely in cardiovascular magnetic resonance (CMR). To date, there is no robust automatic algorithm available that allows the AVPD to be measured clinically in CMR with input in a single timeframe...

BACKGROUND AND AIMS: Right ventricular (RV) functional assessment in premature infants includes basal longitudinal strain (RV BLS), RV systolic tissue Doppler velocity (RV s'), tricuspid annular plane systolic excursion (TAPSE) and RV fractional area change (FAC). A hyperdynamic left ventricle (LV) may influence RV measures of displacement (TAPSE) and velocity (RV s') but not measures of relative change of length (RV BLS) or area (FAC). We aimed to explore this hypothesis in preterm infants with a patent ductus arteriosus (PDA)...

MitraClip (MC) is an alternative therapeutic option for patients with severe mitral regurgitation (MR) who are at high surgical risk. Most candidates for MC have severe heart failure (HF) with increased N-terminal pro-B-type natriuretic peptide (NT-pro BNP) levels. We sought to clarify the response of NT-pro BNP after MC and to identify the determinants of NT-pro BNP nonresponders. Among 136 consecutive patients successfully treated with MC, we excluded 20 patients due to low baseline NT-pro BNP levels and therefore examined 116 patients...
