INTRODUCTION: Myocardial contusion is an entity in chest trauma which is difficult to diagnose. Current practice relies more on cardiac-specific biochemical markers and standard echocardiography, but no gold standard test exists. The application of Tissue Doppler imaging is yet unexplored. AIM: The present study was designed to evaluate cardiac injury in patients with blunt trauma chest using conventional trans-thoracic echocardiography parameters and Tissue Doppler imaging...

In 2005, the combined pulmonary fibrosis and emphysema (CPFE) was first defined as a distinct entity, which comprised centrilobular or paraseptal emphysema in the upper pulmonary lobes, and fibrosis in the lower lobes accompanied by reduced diffused capacity of the lungs for carbon monoxide (DLCO). Recently, the fibrosis associated with the connective tissue disease was also included in the diagnosis of CPFE, although the exposure to tobacco, coal, welding, agrochemical compounds, and tire manufacturing are the most frequent causative agents...

A method is explored for increasing the sensitivity of power-Doppler imaging without contrast enhancement. We acquire 1-10 s of echo signals and arrange it into a 3-D spatiotemporal data array. An eigenfilter developed to preserve all three dimensions of the array yields power estimates for blood flow and perfusion that are well separated from tissue clutter. This method is applied at high frequency (24 MHz pulses) to a murine model of an ischemic hindlimb. We demonstrate enhancements to tissue perfusion maps in normal and ischemic tissues...

To assess the utility of longitudinal ultrasound (US) to quantify volumetric changes in joint soft tissues during the progression of posttraumatic osteoarthritis (PTOA) in mice, and validate the US results with histological findings. A longitudinal cohort of 3-month-old wild-type C57BL/6 male mice received the Hulth-Telhag surgical procedure on right knee to induce PTOA, and sham surgery on their left knee as control. US scans were performed on both knees before, 2, 4, 6, and 8 weeks post-surgery. Joint space volume and Power-Doppler (PD) volume were obtained from US images via Amira software...

Accurate 3-D surface segmentation is a challenging task in echocardiography because of the relatively low image quality. We introduce a new method for 3-D segmentation of the endocardium involving temporal decorrelation of echo signals originating from tissue and blood using radiofrequency (RF) signals acquired in 3-D Doppler mode. Temporal features were extracted in 3-D Doppler mode, where a sequence of RF lines is recorded for each image line. Each set of RF lines is highly correlated because of the high pulse repetition frequency...

Fingertip response to trauma represents a fascinating example of tissue regeneration. Regeneration derives from proliferative mesenchymal cells (blastema) that subsequently differentiate into soft and skeletal tissues. Clinically, conservative treatment of the amputated fingertip under occlusive dressing can shift the response to tissue loss from a wound repair process towards regeneration. When analyzing by Immunoassay the wound exudate from occlusive dressings, the concentrations of brain-derived neurotrophic factor (BDNF) and leukemia inhibitory factor (LIF) were higher in fingertip exudates than in burn wounds (used as controls for wound repair versus regeneration)...

AIM: Metalloproteinases inhibition by doxycycline reduces cardiac protein degradation at extracellular and intracellular level in the experimental model ischemia/reperfusion injury. Since both extracellular cardiac matrix and titin filaments inside the cardiomyocyte are responsible for the myocardial stiffness, we hypothesized that doxycycline could favorably act on left ventricular (LV) filling pressures in patients after reperfused acute ST-elevation myocardial infarction (STEMI). METHODS AND RESULTS: Seventy-three of 110 patients of the TIPTOP trial underwent a 2D-Echo-Doppler on admission, and at pre-discharge and at 6-month after a primary PCI for STEMI and LV dysfunction...

Familial amyloid cardiomyopathy is a challenging condition that mimics many other diseases, particularly in patients with pronounced neurological presentations and unexplained or equivocal cardiac abnormalities. In this case, a 57-year-old man was admitted for outpatient cardiological evaluation of progressive right heart failure and limb paraesthesias. The patient presented with hypertension, chronic Guillain-Barre syndrome, and sick sinus syndrome. Transthoracic echocardiograms showed a thickened ventricular wall and enlarged atrium...

Background.: Non-invasive cardiac output monitoring (NICOM) using bioreactance (BRT) in pregnancy is gaining interest but lacks validation. We compared simultaneous cardiac output (CO) measurements obtained using the NICOM ® (BRT-CO) and echocardiography (echo-CO), and assessed the relationship between maternal characteristics and myocardial performance. Methods.: Paired stroke volume (SV) and CO readings were obtained using NICOM ® and echocardiography, in a group of healthy nulliparous women throughout a 15 min period...

Aims: Transposition of the great arteries (TGA) is generally repaired using the arterial switch operation (ASO) involving coronary transfer. The objective of this prospective study was to determine whether specific coronary Doppler patterns intra-operatively predicted adverse early myocardial events. Methods and results: Patients < 3 months old with TGA undergoing the ASO were eligible. All patients (when feasible) underwent an intra-operative transoesophageal echo (TEE) plus an epicardial echo and had pre-op, early post-op, pre-discharge and follow-up functional echocardiograms...

BACKGROUND: Newer echocardiographic techniques may allow for more accurate assessment of right ventricular function. Adult studies have correlated these echocardiographic measurements with invasive data, but minimal data exist in the paediatric congenital heart population. The purpose of this study was to evaluate echocardiographic measurements that correlate best with right ventricular systolic and diastolic catheterisation parameters. METHODS: Patients with two-ventricle physiology who underwent simultaneous echocardiogram and cardiac catheterisation were included in this study...

REVIEW
Sumeet S Mitter, Sanjiv J Shah, James D Thomas
Diastolic dysfunction represents a combination of impaired left ventricular (LV) relaxation, restoration forces, myocyte lengthening load, and atrial function, culminating in increased LV filling pressures. Current Doppler echocardiography guidelines recommend using early to late diastolic transmitral flow velocity (E/A) to assess diastolic function, and E to early diastolic mitral annular tissue velocity (E/e') to estimate LV filling pressures. Although both parameters have important diagnostic and prognostic implications, they should be interpreted in the context of a patient's age and the rest of the echocardiogram to describe diastolic function and guide patient management...

BACKGROUND: While left atrial (LA) enlargement is known as an early sign of left heart disease with prognostic implications in heart failure (HF), the importance of right atrial (RA) enlargement is less well studied, and the prognostic implications of interatrial size comparison are insufficiently understood. The aim of this study was to test the hypothesis that RA area larger than LA area in apical four-chamber view is associated with all-cause mortality in elderly patients with HF independent of left ventricular ejection fraction (LVEF)...

BACKGROUND: The fetal heart at term is exposed to an increase in hemodynamic work as a consequence of fetal growth, increased circulating volume, and alteration in loading patterns due to maturational changes in fetoplacental circulation. The extent to which these cardiovascular changes influence human fetal and neonatal cardiac adaptation has not been fully elucidated. The aim of this study was to evaluate perinatal cardiovascular changes in ventricular geometry and myocardial performance in normal term fetuses...

Morphea, or localized scleroderma, is an inflammatory disease that leads to sclerosis of the skin and underlying tissues due to excessive collagen deposition. Oral involvement is unusual and it may produce white linear fibrotic areas with a scar-like appearance, atrophy of tongue papillae, gingival recession and alveolar bone resorption. We report a case of a 13-year-old girl who consulted for progressive recession on the attached gingiva of her upper left incisors. She also presented a hypopigmented line on the left side skin of her upper lip, which continued through the vermilion and the lip mucosa, including the gingiva of the affected teeth...

Infants of diabetic mothers (IDMs) with hypertrophic cardiomyopathy are recognized to have impaired myocardial performance, but less is known about ventricular function in IDMs without hypertrophy. We hypothesized that in asymptomatic newborns with normal two-dimensional echocardiographic evaluations, pulsed wave tissue Doppler imaging (TDI) would suggest a subclinical decrease in the cardiac function of IDMs compared to infants of non-diabetics (nIDMs). This is a retrospective cohort study of asymptomatic neonates ≥36 weeks gestation, at 0-7 days of life, with normal standard echocardiograms...

Stress echocardiography (SE) has an established central role as a diagnostic tool in cardiology. It is not only an established method for the diagnostic and prognostic stratification of patients with coronary artery disease but also shows an emerging value for assessment of cardiac function beyond coronary artery disease. The enormous conceptual technological development of ultrasound technology (Doppler, digitizing, tissue Doppler imaging, strain technology, 3‑D-echo and new ultrasound contrast agents) has led to applications of SE in almost all diagnostic fields of cardiology...
