Central Illustration : Position Statement on the Use of Myocardial Strain in Cardiology Routines by the Brazilian Society of Cardiology's Department Of Cardiovascular Imaging - 2023 Proposal for including strain in the integrated diastolic function assessment algorithm, adapted from Nagueh et al.67 Am: mitral A-wave duration; Ap: reverse pulmonary A-wave duration; DD: diastolic dysfunction; LA: left atrium; LASr: LA strain reserve; LVGLS: left ventricular global longitudinal strain; TI: tricuspid insufficiency. Confirm concentric remodeling with LVGLS.

Double lumen aortic arch or persistence of fifth aortic arch?- Report of a case with no associated cardiac defects and literature review.

Different vascular abnormalities have been reported under the denomination of "persistence of the fifth aortic arch." Detailed studies on experimental embryology raised the discussion about the existence of the fifth aortic arch as an embryological structure, both in humans and mammals. In 1969 the Van Praaghs described the occurrence of double left aortic arch, denominating such anomaly as persistence of the fifth arch.

Effective dose of sedation in transesophageal echocardiography: relation to age, body surface area and left ventricle function.

Background: Sedation with midazolam and meperidine is widely used in transesophageal echocardiography. However, no mean dose is established for each individual case.

Objective: To correlate the mean midazolam and meperidine doses for proper sedation for transesophageal echocardiography with age range, body surface area, and left ventricular ejection fraction.

[Evaluation of segmentary contractility in Chagas' disease by using the integral of the myocardial velocity gradient (myocardial strain) obtained through tissue Doppler echocardiography].

Objective: To quantify the percentage of contractility of different myocardial segments in patients with Chagas' disease by measuring myocardial strain and to assess the differences in the radial and longitudinal ventricular contractile function in the undetermined and dilated forms of chronic chagasic cardiomyopathy as compared with those in a group of healthy individuals.

Methods: The study comprised 39 individuals [20 (51.3%) of the male sex] divided into the following 4 groups: 1) Nl: 17 (43.

Coronary artery spasm during dobutamine stress echocardiography in a patient with angiographically normal coronary arteries.

Dobutamine stress echocardiography (DSE) has been extensively used for diagnostic and prognostic purposes in patients with suspected or known coronary artery disease. During DSE transitory alterations of myocardial wall mobility can occur in the absence of electrocardiographic alterations, or they can be associated with ST segment depression or even elevation on the electrocardiogram. ST segment elevation during DSE has been reported as an infrequent event, generally associated with previous myocardial infarction or coronary artery disease with critical lesions, since the positive inotropic and chronotropic effects of dobutamine produce an increase in myocardial oxygen demand, causing ischemia and segmental contractility abnormalities in patients with significant coronary stenosis.

Intracardiac thrombosis and mitral prosthesis dysfunction in systemic lupus erythematosus. A case report.

Systemic lupus erythematosus (SLE) is an inflammatory disease characterized by deposition of autoantibodies and pathogenic immune complexes in the cells and tissues of an organism, causing lesions. The heart is one of the most frequently involved organs, valvar involvement being common (27%) and of great clinical importance. Some studies suggest that valvar involvement is associated with the presence of a specific autoantibody, the antiphospholipid antibody (aPL).

Study of the myocardial contraction and relaxation velocities through Doppler tissue imaging echocardiography: A new alternative in the assessment of the segmental ventricular function.

Objective: Doppler tissue imaging (DTI) enables the study of the velocity of contraction and relaxation of myocardial segments. We established standards for the peak velocity of the different myocardial segments of the left ventricle in systole and diastole, and correlated them with the electrocardiogram.

Methods: We studied 35 healthy individuals (27 were male) with ages ranging from 12 to 59 years (32.
