Position Statement on the Use of Myocardial Strain in Cardiology Routines by the Brazilian Society of Cardiology's Department Of Cardiovascular Imaging - 2023.

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.

Vascular abnormalities in primary amyloidosis.

Aims: Primary amyloidosis (AL) is a systemic disease; however, there is limited information regarding the presence and character of vascular abnormalities.

Methods And Results: Validated ultrasound techniques were used to prospectively determine carotid artery intimal-medial thickness (IMT) and brachial artery flow-mediated dilatation (FMD) in 59 consecutive AL patients and 17 age-similar, healthy, asymptomatic volunteers (CON). Carotid IMT was increased in AL when compared with CON (0.

Echocardiographically guided pericardiocentesis for treatment of clinically significant pericardial effusion in rheumatoid arthritis.

Objective: To assess the safety and efficacy of echocardiographically guided pericardiocentesis for patients with rheumatoid arthritis (RA) and hemodynamically significant pericardial effusion.

Methods: We identified 16 patients with RA who underwent 18 echocardiographically guided pericardiocentesis procedures at our institution over a 20-year period. Clinical and laboratory characteristics of the patients, response to treatment, complications, and need for future pericardial surgery were abstracted from the echocardiography database.

Comparison of usefulness of echocardiographic Doppler variables to left ventricular end-diastolic pressure in predicting future heart failure events.

We sought to determine whether the echocardiographic Doppler parameters of left ventricular diastolic dysfunction predict future heart failure (HF) events and, if so, which parameters best predict HF. We also examined whether the predictive ability of echocardiographic Doppler parameters was related to their prediction of left ventricular end-diastolic pressure (LVEDP). We studied patients who underwent cardiac catheterization and echocardiography performed within a 30-day period.

Left atrial myopathy in cardiac amyloidosis: implications of novel echocardiographic techniques.

Aims: To assess left atrial (LA) function and determine the prevalence of LA dysfunction in AL amyloidosis (AL) using conventional and strain echocardiography.

Methods And Results: LA ejection fraction, LA filling fraction, LA ejection force, peak LA systolic strain rate (LAsSR), and LA systolic strain (LA epsilon) were determined in 95 AL patients (70 with and 25 without echocardiographic evidence of cardiac involvement, abbreviated CAL and NCAL, respectively), 30 age-matched controls (CON), and 20 patients with diastolic dysfunction and LA dilatation (DD). Peak LAsSR >2 standard deviations below mean CON value was used as the cut-off for normal LA function.

Clinical and echocardiographic characteristics of hemodynamically significant pericardial effusions in patients with systemic lupus erythematosus.

Echocardiographic-guided pericardiocentesis was found to be safe and efficacious in treating 11 patients with systemic lupus erythematosus who had hemodynamically significant pericardial effusions. These patients tended to present early in their disease course, and men were more often affected.
