Introduction And Objectives: Transesophageal echocardiography (TEE) is crucial in order to assess aortic anatomy after stroke. Although routinely used to assess cardiovascular anatomy and function, three-dimensional echocardiography (3D TEE) is less used for aortic evaluation. We thus sought to assess prospectively whether additional information on aortic plaque morphology could be obtained with 3D TEE after an ischemic stroke.

Objective: We aimed to correlate COVID-19 Brazilian in-hospital patients' mortality to demographic aspects, biomarkers, tomographic, echocardiographic findings, and clinical events.
Methods: A prospective study, single tertiary center in Brazil, consecutive patients hospitalized with COVID-19.

Rupture of tricuspid valve is unusual, occurring mainly in the setting of blunt trauma or endomyocardial biopsy. Spontaneous tricuspid valve chordal rupture is particularly rare. We report herein a case of a patient with severe pulmonary hypertension, on the lung transplantation waiting list, who presented with spontaneous chordal rupture, exacerbation of tricuspid insufficiency and worsening of clinical status.

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.

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.
Background: Transesophageal echocardiography (TEE) plays an important role in evaluating cardioembolic sources of emboli. The identification of a patent foramen ovale (PFO) is reportedly improved with TEE compared with transthoracic echocardiography (TTE), but the Valsalva maneuver during TEE may be difficult or suboptimal. The aim of this study was to assess the efficacy of the Valsalva maneuver for PFO diagnosis using TEE compared with TTE by evaluating patients with ischemic stroke referred for echocardiography.

Objective: To analyze, with 3D ECHO, the geometric and volumetric modifications of the left ventricle (VE) six months after AMI in patients subjected to percutaneous primary treatment.
Background: Assessment of the right ventricular (RV) function by echocardiography in patients with pulmonary thromboembolism (PTE) is complex and frequently qualitative. Tissue Doppler has been used for the semiquantitative assessment of this chamber, although with some limitations.
Objective: To evaluate RV function in PTE using tissue-Doppler echocardiography, in addition to atrial natriuretic peptide (BNP).
Cardiovascular mortality in kidney transplant recipients has shown to be substantially elevated particularly in the first year of transplantation. Complex ventricular arrhythmia (VA) has been pointed as one of the etiologies of sudden death. The aim of this study was to evaluate the prevalence of VA and to investigate the factors associated with their occurrence in incident kidney transplant recipients.

Objective: 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 with 2D Echo and 3D Echo of 23 patients (17 males, mean age of 57 ± 13 years) with ST-segment elevation acute myocardial infarction, primarily percutaneously treated (stent).
Background: TEE is a semi-invasive tool broadly used and its utilization associated to sedatives drugs might to affect the procedure safety.
Objective: to analyze aspects of TEE safety associated to the use of Midazolan (MZ) and Flumazenil (FL) and the influence of the clinical variables on the event rate.
Method: prospective study with 137 patients that underwent TEE with MZ associated to moderate sedation.
Background: There is a paucity of information concerning left ventricular (LV) dyssynchrony assessment by real time three-dimensional (3D) echocardiography (RT3DE) versus tissue Doppler imaging (TDI).
Aims: To compare RT3DE and TDI LV dyssynchrony assessment.
Methods: A prospective study of 92 individuals (56 men, age 47 +/- 10 years), 32 with dilated cardiomyopathy (CMP), and 60 healthy individuals.
Background: Left ventricular (LV) electromechanical coupling (synchrony) is important in the analysis of the systolic performance, especially for the indication of cardiac resynchronization therapy in patients with advanced CHF.
Objective: To compare LV synchrony as analyzed by real-time three-dimensional (3D) echocardiography (ECHO) with LVEF measurements as obtained with 2D and 3D ECHO.
Methods: Prospective study of 92 individuals (56 men, 47 +/- 10 years of age), of which 60 had normal heart structure (ECHO) and ECG (N group), and 32 had dilated cardiomyopathy (DCM group).
Blood flow requirements of the respiratory muscles (RM) increase markedly during exercise in chronic heart failure (CHF). We reasoned that if the RM could subtract a fraction of the limited cardiac output (QT) from the peripheral muscles, RM unloading would improve locomotor muscle perfusion. Nine patients with CHF (left ventricle ejection fraction = 26 +/- 7%) undertook constant-work rate tests (70-80% peak) receiving proportional assisted ventilation (PAV) or sham ventilation.

Transesophageal echocardiography revealed severe mitral regurgitation caused by the rupture. He successfully underwent emergency mitral valve replacement and was discharged 9 days after the surgical correction.
