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

Maria Luciana Zacarias Hannouche da Trindade, Marcelo Luiz Campos Vieira, Ana Clara Tude Rodrigues, Miguel José Francisco Neto, Claudio Henrique Fischer, Samira Saady Morhy

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.

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.

Robotic surgery in Cardiology: a safe and effective procedure

Robinson Poffo, Alisson Parrilha Toschi, Renato Bastos Pope, Alex Luiz Celullare, Anderson Benício, Claudio Henrique Fischer, [...]

Objective:To evaluate the short and medium-term outcomes of patients undergoing robotic-assisted minimally invasive cardiac surgery.METHODS:From March 2010 to March 2013, 21 patients underwent robotic-assisted cardiac surgery. The procedures performed were: mitral valve repair, mitral valve replacement, surgical correction of atrial fibrillation, surgical correction of atrial septal defect, intracardiac tumor resection, totally endoscopic coronary artery bypass surgery and pericardiectomy.RESULTS:The mean age was 48.39±18.05 years. The mean cardiopulmonary bypass time was 151.7±99.97 minutes, and the mean aortic cross-clamp time was 109.94±81.34 minutes. […]

Assessing prognosis of pulmonary embolism using tissue-Doppler echocardiography and brain natriuretic peptide

Ana Clara Tude Rodrigues, Adriana Cordovil, Cláudia Gianini Mônaco, Laise Antônia Bonfim Guimarães, Wércules Antônio Alves de Oliveira, Claudio Henrique Fischer, [...]

DOI: 10.1590/S1679-45082013000300013

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 […]

Patients diagnosed with multiple myeloma are more susceptible to infections which are the major causes of morbidity and mortality associated to this disease. The main infectious agents involved are Gram-positive bacteria. However, after chemotherapy an increase in the incidence of Gram-negative strains is observed. These bacteria are also responsible for most cases of urinary tract infections. Here is reported a rare case in a 73-year-old man with multiple myeloma who developed endocarditis due to pseudomonas.

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 […]
