Streptococcus gallolyticus infective endocarditis in a patient with systemic lupus erythematosus: a three-dimensional echocardiography evaluation
A 42 year-old woman was referred to our hospital with a history of fever and poor general status for the last 30 days. She presented tachycardia and a systolic apical murmur. Laboratory tests revealed leukocytosis of 13,100/mL, hemoglobin of 8.4g/dL and positive systemic lupus erythematosus antibodies (anti-Ro/SSA, anti-La/SSB, anticardiolipin, and antinuclear antibodies); blood culture was positive for Streptococcus gallolyticus. Three-dimensional transesophageal echocardiography was performed and revealed multiple mitral valve vegetations, with leaflet perforation and important mitral regurgitation, as well as […]
Contrast echocardiography in myocardial infarction
The contrast agents used in ultrasound are approved for several clinical situations. New echocardiographic techniques, such as harmonic imaging and power pulse inversion imaging, can improve the visualization of microbubbles. In this article we discuss the early development of contrast echocardiography, new technologies that help improve image acquisition and its practical role in the assessment of myocardial infarction.
Clinical and echocardiographic characteristics associated with the evolution of the ductus arteriosus in the neonate with birth weight lower than 1,500g
Objective:To identify clinical and echocardiographic parameters associated with the evolution of the ductus arteriosus in neonates with birth weight lower than 1,500g.METHODS:Retrospective study of 119 neonates in which clinical parameters (Prenatal: maternal age, risk of infection and chorioamnionitis, use of corticosteroid, mode of delivery and gestational age. Perinatal: weight, Apgar score, gender and birth weight/gestational age classification; Postnatal: use of surfactant, sepsis, fluid intake, heart murmur, heart rate, precordial movement and pulses, use of diuretics, oxygenation index, desaturation/apnea, ventilatory support, […]
Caseous calcification of the mitral annulus: case report
We present a rare case of probable caseous calcification of the mitral. This pathology is more frequently detected in asymptomatic women older than 70 years. To recognize this image is important because echocardiography is the easiest way to elucidate this diagnosis, and more importantly because this structure could be easily misdiagnosed as tumors, thrombus and vegetations, which are much more common. Normally, it has a benign evolution, and the correct diagnosis is crucial to avoid unnecessary surgical interventions.
Assessing prognosis of pulmonary embolism using tissue-Doppler echocardiography and brain natriuretic peptide
Objective:To assess prognosis of pulmonary thromboembolism using tissue Doppler echocardiography and brain natriuretic peptide.METHODS:Patients aged over 18 years were evaluated within 24 hours of confirmed diagnosis (chest tomography/pulmonary scintigraphy) of pulmonary embolism using two-dimensional echocardiography and tissue Doppler for right ventricular systolic (s’) velocities, strain, tissue tracking and myocardial performance index. Plasma brain natriuretic peptide was also obtained within 24 hour. The influence of echocardiographic and clinical variables on mortality was examined (up to 12 months) using Cox regression analysis.RESULTS:Out […]
Relation between three-dimensional and two-dimensional echocardiography and biochemical analysis in patients with ST-segment elevation myocardial infarction percutaneously treated
ABSTRACTObjective:The prognosis of patients with acute myocardial infarction depends on multiple features that can demonstrate myocardial injury degree (such as serum markers of cardiac necrosis), and also on adaptive mechanisms relative to the acute event. The aim of the study was to assess the relation between biochemical and echocardiographic findings from three-dimensional echocardiographic (3D Echo) analysis and echocardiographic two-dimensional (2D Echo) left ventricular ejection fraction in patients with ST-segment elevation acute myocardial infarction, submitted to primary percutaneous treatment.Methods:A prospective study […]
