Project description:ObjectivesThis study aims to correlate subclinical echocardiographic features with the clinical, laboratory, and therapeutic profiles of the patients to characterize risks for systemic lupus erythematosus (SLE) cardiac diseases.MethodsThe study included 59 SLE patients. Demographic data, disease characteristics, and current therapies were recorded, and the anthropometric measurements and routine laboratory tests were performed. The disease activity by the SLE Disease Activity Index-2K (SLEDAI2K) and the presence of metabolic syndrome (MetS) were assessed. Two-dimensional echocardiography was performed.ResultsThe mean age of the patients was 31.3 ± 10.5 years, and the disease duration was 5.18 ± 4.1 years. 86.4% of the patients were females. Cardiac presentations by echocardiography were mainly mitral regurgitation (33.9%), tricuspid regurgitation (32.2%), mitral thickening (18.6%), aortic thickening (13.6%), pericardial effusion (13.6%), and pulmonary hypertension (8.5%) in order of frequency. The frequency of different echocardiographic findings with respect to other clinical phenotypes showed peaks with renal disease, MetS, and leukopenia. Components of MetS (triglycerides, high systolic blood pressure) and avascular necrosis were significant predictors for pericardial diseases (OR=1.011 CI 95% 1-1.022, p=0.046, OR=1.157 CI 95% 1.025-1.307, p=0.018, and OR=74.78 CI 95% 2.52-2215.76, p=0.013, respectively), and it is likely that hydroxychloroquine was protective against them. Age of the patients was a significant predictor for tricuspid regurgitation (OR=1.063 CI 95% 1.004-1.126, p=0.036). Mucosal ulcers were negative predictors for mitral thickening and regurgitation (OR=0.2 CI 95% 0.059-0.673, p=0.009). The use of corticosteroids appeared to protect against a number of valve lesions especially tricuspid regurgitation (OR=0.299 CI 95% 0.088-1.019, p=0.054).ConclusionThis study highlighted different echocardiographic features and identified clinical predictors of different cardiac pathologies aiming to determine patients at risk and improve the prognosis of SLE cardiac diseases.

Project description:BackgroundCardiac amyloidosis is an important cause for heart failure with preserved ejection fraction. It is often under diagnosed due to the fact that clinicians do not always recognize the specific diagnostic findings associated with this disease, also leading to the wrong diagnosis. When left untreated further irreversible organ dysfunction occurs, with high morbidity and mortality rates.Case summaryA 71-year-old patient presented with progressive exertional dyspnoea and angina pectoris at the outpatient clinic. Medical history noted a percutaneous coronary intervention of the right coronary artery due to stable angina pectoris. The electrocardiogram showed low voltage in the limb leads and pseudo-infarct pattern in the precordial leads. Echocardiographic findings included left and right ventricular hypertrophy, decreased left ventricular systolic function, restrictive diastolic function, and 'relative' apical sparing of the left ventricle. This led to the suspicion of cardiac amyloidosis, which was confirmed with a positive bone scintigraphy using 99mTechnecium-DPD and the absence of monoclonal proteins. Treatment with Tafamidis was initiated.DiscussionElectrocardiographic findings suggestive of cardiac amyloidosis are low voltage in the limb leads and/or a pseudo-infarct pattern in the precordial leads. Important echocardiographic findings are left and right ventricular hypertrophy, restrictive diastolic function, 'relative' apical sparing of the left ventricle and impaired left atrial strain. The next step in confirming the diagnosis is 99mTechnecium PYP/DPD/HMDP bone scintigraphy and testing for monoclonal proteins. The diagnosis ATTR amyloidosis is confirmed by the combination of positive bone scintigraphy (Perugini Grade 2 or 3) and the absence of monoclonal proteins, without the necessity of performing an endomyocardial biopsy.

Project description:Cardiac amyloidosis (CA) may affect all cardiac structures, including the valves. From 423 patients undergoing a diagnostic workup for CA we selected 2 samples of 20 patients with amyloid transthyretin (ATTR-) or light-chain (AL-) CA, and age- and sex-matched controls. We chose 31 echocardiographic items related to the mitral, aortic and tricuspid valves, giving a value of 1 to each abnormal item. Patients with ATTR-CA displayed more often a shortened/hidden and restricted posterior mitral valve leaflet (PMVL), thickened mitral chordae tendineae and aortic stenosis than those with AL-CA, and less frequent PMVL calcification than matched controls. Score values were 15.8 (13.6-17.4) in ATTR-CA, 11.0 (9.3-14.9) in AL-CA, 12.8 (11.1-14.4) in ATTR-CA controls, and 11.0 (9.1-13.0) in AL-CA controls (p = 0.004 for ATTR- vs. AL-CA, 0.009 for ATTR-CA vs. their controls, and 0.461 for AL-CA vs. controls). Area under the curve values to diagnose ATTR-CA were 0.782 in patients with ATTR-CA or matched controls, and 0.773 in patients with LV hypertrophy. Patients with ATTR-CA have a prominent impairment of mitral valve structure and function, and higher score values. The valve score may help identify patients with ATTR-CA among patients with CA or unexplained hypertrophy.

Project description:BackgroundIn recent decades, novel echocardiographic measures have constantly emerged. It is still unclear which echocardiographic measures have the most significant prognostic value in the general population. Accordingly, the aim of this study was to compare the prognostic value of a large panel of echocardiographic measures to identify the most promising measures.MethodsA total of 1,497 Framingham study participants (mean age, 65 years; 55.4% women) who underwent echocardiographic measurements of left ventricular ejection fraction, left ventricular mass index, global longitudinal strain, global circumferential strain, mitral annular plane systolic excursion, mitral E/e' ratio, maximum and minimum left atrial (LA) volume index, LA emptying fraction, and left ventricular longitudinal synchrony were evaluated. These measures were related to the incidence of two composite outcomes: cardiovascular disease (CVD) or death and atrial fibrillation (AF) or congestive heart failure (CHF).ResultsOn follow-up (mean, 8.3 years), there were 241 CVD events or deaths and 139 AF or CHF events. In multivariate-adjusted Cox models, higher LA emptying fraction was associated with a lower risk (hazard ratios per SD, 0.80 and 0.70 for CVD or death and AF or CHF, respectively; P ≤ .001 for both) while higher minimum LA volume index (hazard ratios per SD, 1.32 and 1.70 for CVD or death and AF or CHF, respectively; P ≤ .001 for both) and maximum LA volume index (hazard ratios per SD, 1.26 and 1.54 for CVD or death and AF or CHF, respectively; P ≤ .002 for both) were associated with a higher risk for both composite outcomes.ConclusionsIn this community-based sample, LA volumes and function were the best echocardiographic predictors of clinical outcomes. Therefore, these values should be considered for inclusion in standard echocardiographic assessments for the purpose of risk stratification.

Project description:A 12-year-old spayed female miniature Poodle presented for coughing, respiratory distress, and anorexia. After thoracentesis for pleural effusion, radiography revealed an enlarged cardiac silhouette with a bulge in the area of the body of the right atrium. Echocardiography revealed an anechoic chamber-like cavity lateral to the right atrium that communicated with the right atrium through a 13 mm defect in the right atrial free wall. Contrast echocardiography and color flow Doppler were used to prove that the cavity communicated with the right atrium. The cavity was diagnosed as a giant right atrial diverticulum.

Project description:AimsTransthyretin amyloid cardiomyopathy (ATTR-CM) is an increasingly diagnosed disease. Echocardiography is widely utilized, but studies to confirm the value of echocardiography for tracking changes over time are not available. We sought to describe (i) changes in multiple echocardiographic parameters; (ii) differences in rate of progression of three predominant genotypes; and (iii) the ability of changes in echocardiographic parameters to predict prognosis.Methods and resultsWe prospectively studied 877 ATTR-CM patients attending our centre between 2000 and 2020. Serial echocardiography findings at baseline, 12 months and 24 months were compared with survival. Overall, 565 patients had wild-type ATTR-CM and 312 hereditary ATTR-CM (201 with V122I; 90 with T60A). There was progressive worsening of structural and functional parameters over time, patients with V122I ATTR-CM showing more rapid worsening of left and right ventricular structural and functional parameters compared to both wild-type and T60A ATTR-CM. Among a wide range of echocardiographic analyses, including deformation-based parameters, only worsening in the degree of mitral (MR) and tricuspid regurgitation (TR) at 12- and 24-month assessments was associated with worse prognosis (change at 12 months: MR, hazard ratio 1.43 [95% confidence interval 1.14-1.80], p = 0.002; TR, hazard ratio 1.38 [95% confidence interval 1.10-1.75], p = 0.006). Worsening in MR remained independently associated with poor prognosis after adjusting for known predictors.ConclusionIn ATTR-CM, echocardiographic parameters progressively worsen over time. Patients with V122I ATTR-CM demonstrate the most rapid deterioration. Worsening of MR and TR were the only parameters associated with mortality, MR remaining independent after adjusting for known predictors.
