The rapid technological developments of the past decade and the changes in echocardiographic practice brought about by these developments have resulted in the need for updated recommendations to the previously published guidelines for cardiac chamber quantification, which was the goal of the joint writing group assembled by the American Society of Echocardiography and the European Association of Cardiovascular Imaging. This document provides updated normal values for all four cardiac chambers, including three-dimensional echocardiography and myocardial deformation, when possible, on the basis of considerably larger numbers of normal subjects, compiled from multiple databases. In addition, this document attempts to eliminate several minor discrepancies that existed between previously published guidelines. [less ▲]

Echocardiography is one of the most powerful diagnostic and monitoring tools available to the modern emergency/critical care practitioner. Currently, there is a lack of specific European Association of Cardiovascular Imaging/Acute Cardiovascular Care Association recommendations for the use of echocardiography in acute cardiovascular care. In this document, we describe the practical applications of echocardiography in patients with acute cardiac conditions, in particular with acute chest pain, acute heart failure, suspected cardiac tamponade, complications of myocardial infarction, acute valvular heart disease including endocarditis, acute disease of the ascending aorta and post-intervention complications. Specific issues regarding echocardiography in other acute cardiac care scenarios are also described. [less ▲]

During the course of and after a myocardial ischemia-reperfusion insult, ventricular arrhythmia (VA) may have several single or overlapping potential substrates. Some of these may not be associated with morphological and functional changes, whereas others may have individual susceptibility. Nevertheless, cardiac magnetic resonance currently offers a comprehensive and highly effective toolset for the evaluation of a risk of VA on a patient basis after a myocardial infarction. Indeed, cardiac magnetic resonance has established itself as a reference for the evaluation of the myocardial function and properties, using respectively, cine and tissue characterization imaging to detect and evaluate the extent of acute myocardial injuries, scars and remodeling. This article describes and discusses imaging strategies used to evaluate the substrates for VA in the setting of a myocardial infarction. [less ▲]

AIMS: Reference values for Doppler parameters according to age and gender are recommended for the assessment of heart physiology, specifically for left ventricular (LV) diastolic function. In this study, we report normal reference ranges for Doppler parameters obtained in a large group of healthy volunteers. Echocardiographic data were acquired using state-of-the-art cardiac ultrasound equipment following Doppler acquisition and measurement protocols approved by the European Association of Cardiovascular Imaging. METHODS AND RESULTS: A total of 449 (mean age: 45.8 +/- 13.7 years) healthy volunteers (198 men and 251 women) were enrolled at the collaborating institutions of the Normal Reference Ranges for Echocardiography (NORRE) study. A comprehensive echocardiographic examination was obtained from all subjects following predefined protocols. The majority of the Doppler diastolic parameters (e', E/e') as well as right ventricle systolic s' wave velocity were similar in men and women. Left ventricle s' wave velocity was higher in men than in women. E wave and e' were higher in younger subjects and decreased progressively in the older ones. E/e' ratio increased with ageing. Septal e' <8 cm/s was present in 19.7% of the subjects in the 40-60 year group and in 55% of those in the >/=60 year group. However, the cut-off value of average E/e' or lateral E/e' remained <15 or 13, respectively, in the majority of patients. CONCLUSION: The NORRE study provides the reference values for the most useful Doppler parameters in the evaluation of heart physiology. These data highlight the need of using age-specific reference values especially for the diagnosis of LV systolic and diastolic dysfunction and for the estimation of LV filling pressures. [less ▲]

Over the last decade there has been a remarkable increase in prosthetic heart valve replacement and cardiac implantable electronic device utilization. Although capable of improving the quality and quantity of life of patients suffering from severe valvular heart disease or rhythm disorders, they are both subject to potentially life-threatening infection involving the endocardium, referred to as device infective endocarditis (DIE)1,2. The rate of prosthetic valve endocarditis (PVE) ranges from 1-6% to 15%, being higher in revision surgery1. The infection usually involves the junction between the sewing ring and the annulus, leading to perivalvular abscess, dehiscence, pseudo-aneurysms, and fistulae, or the leaflets of the prosthesis, leading to vegetations, cusp rupture, and perforation. Cardiac device-related infective endocarditis (CDRIE), to be distinguished from local device infection (pocket/generator), is defined as an infection involving the electrode leads, cardiac valve leaflets, or endocardial surface. An incidence of 1.4 per 1000 device-years of definite CDRIE has been reported3. DIE may occur at anytime, being related to surgery only in early cases. [less ▲]

B-type natriuretic peptide (BNP) is often used as a complementary finding in the diagnostic work-up of patients with aortic stenosis (AS). Whether soluble ST2, a new biomarker of cardiac stretch, is associated with symptomatic status and outcome in asymptomatic AS is unknown. sST2 and BNP levels were measured in 86 patients (74+/-13 years; 59 asymptomatic, 69%) with AS (<1.5 cm2) and preserved left ventricular ejection fraction who were followed-up for 26+/-16 months. Both BNP and sST2 were associated with NYHA class but sST2 (>23 ng/mL, AUC = 0.68, p<0.01) was more accurate to identify asymptomatic patients or those who developed symptoms during follow-up. sST2 was independently related to left atrial index (p<0.0001) and aortic valve area (p = 0.004; model R2 = 0.32). A modest correlation was found with BNP (r = 0.4, p<0.01). During follow-up, 29 asymptomatic patients (34%) developed heart failure symptoms. With multivariable analysis, peak aortic jet velocity (HR = 2.7, p = 0.007) and sST2 level (HR = 1.04, p = 0.03) were independent predictors of cardiovascular events. In AS, sST2 levels could provide complementary information regarding symptomatic status, new onset heart failure symptoms and outcome. It might become a promising biomarker in these patients.

BACKGROUND: Mitral regurgitation is a frequent valvular heart disease affecting around 2.5 % of the population with prevalence directly related to aging. Degeneration of mitral valve is broadly considered as a passive ongoing pathophysiological process and little is known about its physiological deregulation. The purpose of this study was to highlight new biomarkers of mitral regurgitation in order to decipher the underlying pathological mechanism as well as to allow the diagnosis and the monitoring of the disease. RESULTS: Modulation of various blood proteins expression was examined in patients suffering from different grades of mitral regurgitation (mild, moderate and severe) compared to healthy controls. To this end, several routine clinical assays and the multi analyte profile technology targeting 184 proteins were used. High-density lipoprotein, apolipoprotein-A1, haptoglobin and haptoglobin-alpha2 chain levels significantly decreased proportionally to the degree of mitral regurgitation when compared to controls. High-density lipoprotein and apolipoprotein-A1 levels were associated with effective regurgitant orifice area and regurgitant volume. Apolipoprotein-A1 was an independent predictor of severe mitral regurgitation. Moreover, with ordinal logistic regression, apolipoprotein-A1 remained the only independent factor associated with mitral regurgitation. In addition, myxomatous mitral valves were studied by immunocytochemistry. We observed an increase of LC3, the marker of autophagy, in myxomatous mitral valves compared with healthy mitral valves. CONCLUSION: These potential biomarkers of mitral regurgitation highlighted different cellular processes that could be modified in myxomatous degenerescence: reverse cholesterol transport, antioxidant properties and autophagy.

OBJECTIVES: Cardiovascular involvement is recognized as a poor prognostic factor in systemic sclerosis (SSc). The aim of this study was to evaluate the usefulness of nailfold video-capillaroscopy (NVC), brain natriuretic peptide (BNP) blood level and exercise echocardiography to predict the occurrence of cardiovascular events in SSc. METHODS: We prospectively enrolled 65 patients with SSc (age 54+/-14 years, 30% female) followed in CHU Sart-Tilman, Liege, Belgium. All patients underwent graded semi-supine exercise echocardiography. Both baseline resting pulmonary hypertension (PH) and PH during follow-up (FUPH) were defined as systolic pulmonary arterial pressure (sPAP)>35 mmHg, and exercise-induced PH (EIPH) as sPAP>50 mmHg during exercise. RESULTS: EIPH was present in 21 patients. During FU (27+/-18 months), 13 patients developed FUPH and 9 presented cardiovascular complications. Patients with cardiovascular events were significantly older (63+/-14 vs 52+/-13 years; P=0.03), presented more frequently NVC grade>2 (89 vs 43%; P=0.009), had higher resting and exercise sPAP (30+/-6 vs 24+/-6; P=0.007 and 57+/-13 vs 44+/-13 vs mmHg; P=0.01, respectively), and higher BNP blood level (112+/-106 vs 26+/-19 pg/ml; P=0.0001). After adjustment for age and gender, NVC grade>2 (ss=2.4+/-1.1; P=0.03), EIPH (ss=2.30+/-1.13; P=0.04), FUPH (ss=0.24+/-0.09; P=0.01 and ss=3.52+/-1.16; P=0.002, respectively;) and BNP (ss=0.08+/-0.04; P=0.02) were independent predictors of CV events. Beyond age, an incremental value of EIPH, BNP and NVC grade>2 was predictive of cardiovascular events (P<0.001). CONCLUSION: Cardiovascular complications are not rare in SSc (18%). NVC, BNP blood level assessment and exercise echocardiography could be useful tools to identify patients at risk of SSc. [less ▲]

BACKGROUND: Cardiac magnetic resonance (CMR) is increasingly used for the diagnosis and management of cardiac diseases. Recent studies have reported immediate post-CMR DNA double-strand breaks in T lymphocytes. We sought to evaluate CMR-induced DNA damage in lymphocytes, alterations of blood cells, and their temporal persistence. METHODS AND RESULTS: In 20 prospectively enrolled healthy men (31.4+/-7.9 years), blood was drawn before and after (1-2 hours, 2 days, 1 month, and 1 year) unenhanced 1.5T CMR. Blood cell counts, cell death, and activation status of lymphocytes, monocytes, neutrophils, and platelets were evaluated. The first 2-hour post-CMR were characterized by a small increase of lymphocyte B and neutrophil counts and a transient drop of total lymphocytes because of a decrease in natural killer cells. Among blood cells, only neutrophils and monocytes displayed slight and transient activation. DNA double-strand breaks in lymphocytes were quantified through flow cytometric analysis of H2AX phosphorylation (gamma-H2AX). gamma-H2AX intensity in T lymphocytes did not change early after CMR but increased significantly at day 2 </=1 month before returning to baseline levels of 1-year post-CMR. CONCLUSIONS: Unenhanced CMR is associated with minor but significant immediate blood cell alterations or activations figuring inflammatory response, as well as DNA damage in T lymphocytes observed from day 2 until the first month but disappearing at 1-year follow-up. Although further studies are required to definitely state whether CMR can be used safely, our findings already call for caution when it comes to repeat this examination within a month. [less ▲]
