RESUMO

Cardiac manifestations develop in the majority of patients with systemic lupus erythematosus (SLE) at some time during the course of their disease. This study was designed to assess cardiac abnormalities in patients with SLE by echocardiography and to compare the 2 groups of patients with and without cardiac manifestations. It was a transversal, descriptive study, conducted in the Internal Medicine Department at the Military Hospital of Tunis from January 2016 to June 2018. Eighty lupus patients, diagnosed on the basis of ACR (American college of rheumatology) criteria, were enrolled in the study and were evaluated by standard echocardiography with color Doppler. Out of 80 patients 42 (52%) had abnormal echocardiographic findings. Pericardial effusion was found in 55%, valvular abnormalities in 52% and 38% had pulmonary hypertension. Patients with pleural effusion (45 vs 15%) were more vulnerable to cardiac involvement as well as renal impairment (57 vs 44%). The difference, however, were not statistically significant (p>0.05) in the renal involvement. Active disease with low complement (80%) was associated with higher frequency of cardiac involvement than disease in remission (64%) but the result was not statistically significant (p=0.11). Cardiac abnormalities are very common in lupus patients even when clinically asymptomatic form. Echocardiography is an excellent non-invasive tool for cardiac evaluation. Their research must be systematic with echocardiography in order to reduce subsequent cardiac morbidity and mortality among the lupus patients.

RESUMO

RATIONALE: Cardiac amyloidosis, considered for the last years to be a rare disease, is one of the determinants of HFpEF. The non-specific clinical presentation and the difficulties related to endomyocardial biopsy have made cardiac amyloidosis an underdiagnosed clinical entity. Improvement of non-invasive diagnostic techniques and the development of new therapies increased clinical awareness for this form of restrictive cardiomyopathy. We here summarize echocardiography and Tc-HDP scintigraphy findings in 6 cases of cardiac amyloidosis and review the literature data of this progressive and fatal cardiomyopathy. PATIENTS CONCERNS: The main clinical manifestations were fatigue, low exercise tolerance and edemas. The right heart failure symptoms usually dominated the clinical picture. DIAGNOSES: All cases were evaluated by echocardiography; 3 cases were further examined by bone scintigraphy and 4 cases a peripheral biopsy was performed. Electrocardiography showed low-voltage QRS complexes and "pseudo-infarct" pattern in the precordial leads, contrary to the echocardiographic aspect, which revealed thickening of ventricle walls. Biatrial dilation and diastolic disfunction were observed. Impaired systolic function was detected in advanced stages of the disease. Tc-HDP scintigraphy revealed cardiac uptake of radiopharmaceutical and managed to confirm the diagnosis in 1 case of cardiac amyloidosis in which salivary gland biopsy was negative. INTERVENTIONS: The treatment was based on managing fluid balance, with the mainstream therapy represented by diuretics. Neurohormonal agents, usually used in heart failure treatment were avoided, due to poor tolerance and worsening of disease course. The management of these 6 cases was challenging due to the refractory manifestation of congestive heart failure. OUTCOMES: During follow-up, 4 of the 6 patients from the current study died in the first year after the final diagnosis was established. LESSONS: Nuclear imaging of cardiac amyloidosis has a revolutionary development nowadays. Bone scintigraphy presents promising results for identifying patients at early stages of disease and to differentiate between cardiac amyloidosis types. Further studies are necessary for the standardization of imaging protocol and development of non-invasive diagnostic tools, especially in assessing the response to treatment and disease progression, for which little is known.

RESUMO

A useful biomarker for detecting cardiac amyloidosis (CA) has not been fully established. We aimed to investigate the utility of several biomarkers to detect CA in patients with amyloid light-chain (AL) amyloidosis.We examined the plasma levels of B-type natriuretic peptide (BNP), N-terminal fragment of the pro-brain natriuretic peptide (NT-proBNP), high-sensitivity cardiac troponin T (hs-cTnT), serum amyloid A, and the difference between kappa and lambda free light chain (dFLC) between CA patients (n = 30, 47.6%) and non-CA patients (n = 33, 52.4%). Levels of BNP were significantly higher in the CA group compared to the non-CA group (1200.0 versus 224.0 pg/mL, P = 0.001). From the ROC analysis, the sensitivity and specificity of BNP for detecting CA (with a cut-off value of 412 pg/mL) were 83% and 70%, respectively, and the area under the receiver operating curve was 0.75 (95% CI 0.61-0.90, P < 0.001) in all AL amyloidosis patients (n = 63). In contrast, other markers such as NT-proBNP, hs-cTnT, serum amyloid A, and dFLC were not useful for detecting CA in AL amyloidosis patients. Additionally, in the Cox proportional hazard analysis, BNP was a predictor of all-cause mortality (hazard ratio 3.266, 95% confidence interval 1.498-7.119, P = 0.003).BNP is a useful biomarker for detecting cardiac involvement and predicting prognosis in AL amyloidosis patients.

RESUMO

Color Doppler ultrasound is the diagnostic cornerstone of vascular assessment. Almost all arteries and veins of the human body are accessible to this diagnostic imaging, which as a result is very often used as first-line diagnostic test. Recent technological developments in high-end ultrasound machines enable us to optimize image quality in color-coded duplex ultrasound of arteries and veins. To obtain an optimal instrument setting, all relevant adjustments of imaging must be considered. In B-Mode ultrasound, the basic vascular imaging method, the most important settings to optimize are ultrasound frequency, gain, dynamic range, and focus, whereas color Doppler depends on angle supersonic sounding and its application in clinical practice. Most mistakes in measuring blood flow velocities, a frequent cause of misinterpretation, result from insufficient angle correction. Cardiac pathologies may result in typical changes of arterial and venous Doppler curves.

RESUMO

Over the last 15 years, cardiovascular magnetic resonance (CMR) imaging has progressively evolved to become an indispensable tool in cardiology. It is a non-invasive technique that enables objective and functional assessment of myocardial tissue. Recent innovations in magnetic resonance imaging scanner technology and parallel imaging techniques have facilitated the generation of T1 and T2 parametric mapping to explore tissue characteristics. The emergence of strain imaging has enabled cardiologists to evaluate cardiac function beyond conventional metrics. Significant progress in computer processing capabilities and cloud infrastructure has supported the growth of artificial intelligence in CMR imaging. In this review article, we describe recent advances in T1/T2 mapping, myocardial strain, and artificial intelligence in CMR imaging.

RESUMO

PURPOSE: A three-dimensional (3D) image from computed tomography (CT) angiography is a useful method for evaluation of complex anatomy such as congenital heart disease. However, 3D imaging requires high contrast enhancement for distinguishing between blood vessels and soft tissue. To improve the contrast enhancement, many are increasing the injection rate. However, one method is the use of fenestrated catheters, it allows use of a smaller gauge catheter for high-flow protocols. The purpose of this study was to compare the pressure of injection rate and CT number of a 24-gauge fenestrated catheter with an 22-gauge non-fenestrated catheter for i.v. contrast infusion during CT. METHODS: Between December 2014 and March 2015, 50 newborn patients were randomly divided into two protocols; 22-gauge conventional non-fenestrated catheter (24 newborn; age range 0.25-8 months, body weight 3.6±1.2 kg) and 24-gauge new fenestrated catheter (22 newborn; age range 0.25-12 months, body weight 3.3±0.9 kg). Helical scan of the heart was performed using a 64-detector CT (LightSpeed VCT, GE Healthcare) (tube voltage 80 kV; detector configuration 64×0.625 mm, rotation time 0.4 s/rot, helical pitch 1.375, preset noise index for automatic tube current modulation 40 at 0.625 mm slice thickness). RESULTS: We compared the maximum pressure of injection rate, CT number of aortic enhancement, and CT number of pulmonary artery enhancement between both protocols. The median injection rate, CT number of aortic enhancement, and CT number of pulmonary artery enhancement were 0.9 (0.5-3.4) ml/s, 455.5 (398-659) HU, and 500.0 (437-701) HU in 22-gauge conventional non-fenestrated catheter and 0.9 (0.5-2.0) ml/s, 436.5 (406-632) HU, and 479.5 (445-695) HU in the 24-gauge fenestrated catheter, respectively. There are no significantly different between a 24-gauge fenestrated catheter and 22-gauge non-fenestrated catheters at injection rate and CT number. Maximum pressure of injection rate was lower with 24-gauge non-fenestrated catheters (0.33 kg/cm2) than 22-gauge non-fenestrated catheters (0.55 kg/cm2) (p<0.01Conclusion: A 24-gauge fenestrated catheter performs similarly to an 22-gauge non-fenestrated catheter with respect to i.v. contrast infusion and aortic enhancement levels and can be placed in most subjects whose veins are deemed insufficient for an 22-gauge catheter.

RESUMO

El cateterismo cardíaco en niños ha mostrado un avance significativo en las últimas décadas, transformándose de un procedimiento casi exclusivamente diagnóstico en sus inicios a un método predominantemente terapéutico en la actualidad. Para ello han contribuido la aparición de múltiples tecnologías de imágenes, así como el creciente desarrollo de materiales de muy bajo perfil y gran versatilidad que permiten el empleo de dispositivos cada vez más específicos para tratar adecuadamente un sinnúmero de enfermedades cardíacas con gran eficacia y seguridad. Esta tendencia continúa creciendo día a día, con la ayuda de nuevas modalidades de tratamiento híbrido donde cardiólogos intervencionistas y cirujanos cardiovasculares interactúan para ayudarse mutuamente, de manera tal de resolver los problemas existentes o aquellos que se van generando con el correr de los años y que afectan la vida de nuestros pacientes. Existen aún como es lógico controversias en algunos casos especiales, que se irán resolviendo paulatinamente en base a la evidencia reunida con las diferentes terapéuticas médicas utilizadas para mejorar el presente y futuro de los niños con cardiopatías (AU)


Cardiac catheterization in children has shown significant progress in recent decades, transforming from an initially almost exclusively diagnostic procedure to a predominantly therapeutic method today. The emergence of multiple imaging technologies has contributed to this progress, as has the growing development of very low-profile and highly versatile materials that allow the use of increasingly specific devices to adequately treat different types of heart disease with great efficacy and safety. This trend continues to grow day by day, with the help of new hybrid treatment modalities where interventional cardiologists and cardiovascular surgeons interact with mutual support, in order to solve existing problems or those that are generated over the years affecting the lives of our patients. Obviously, there are still controversies in specific cases, which will gradually be resolved based on the evidence that becomes available with the use of different medical therapies used to improve the present and future of children with heart disease.(AU)

RESUMO

Coronarography consists in selective angiography of the coronary arteries obtained invasively. It represents the gold standard for the anatomical exploration of the coronary arteries and establishes the first step for the indication of possible percutaneous or surgical revascularisation. According to substantial progress, it represents an essential diagnostic tool frequently used with, despite its invasive characteristic, a very low complication's rate. The present article describes the patient's preparation for this procedure, technical modalities, major indications, contraindications and possible complications.

RESUMO

The noninvasive evaluation of cardiac morphology and function by echocardiography is an essential part of modern intensive care therapy. However, this procedure can be challenging and beginners often lack the ability to objectively state the correct global and regional myocardial function. Recent developments allow a semi-automatic deformation (strain) analysis by a couple of more objective respective parametric techniques. Strain describes the change in length of a myocardial segment during the cardiac cycle. While this is primarily a regional analysis, an insight into the global left ventricular deformation is possible by averaging all relevant segments. Speckle tracking echocardiography (STE) is actually the only clinically relevant technique and is well scientifically and clinically approved. The advantages of STE are the angle-independency, the ease and fastness of its use, the availability at the bedside and low costs. Through proven good reproducibility it should be a good method for repeated analysis even by different echocardiographers. However, actually the greatest disadvantage is the variation of measures between different vendors of ultrasound machines and software-packages. At the moment, a task force of leading echocardiography experts and industry personal is working on a solution. Normal values have been published for healthy collectives and STE has been in use in the majority of cardiac diseases. Besides from a few research studies, the usage in critically ill patients actually is still limited.

RESUMO

Pulmonary arterial hypertension (PAH) is a serious and often fatal complication of connective tissue disease (CTD). Right atrial (RA) function is essential to maintaining adequate total right heart function in PAH. However, little is known about prognostic utility of RA function in CTD-PAH. RA longitudinal strain (LS) and strain rate (LSR) were evaluated in 53 consecutive patients (51 female, mean age 42 ± 15 years) with CTD-PAH, including systemic lupus erythematosus (SLE) (33.7%), mixed connective tissue disease (MCTD) (32.1%), primary Sjögren's syndrome (pSS) (26.4%), and systemic sclerosis (SSc) (3.8%). At a mean follow-up of 19.3 ± 10.9 months, 20 patients (37.7%) were clinically worse. The group with clinical events had worse clinical conditions and poorer RA function at baseline compared with the group that had no clinical events. RA LS independently reflected World Health Organization functional class (WHO FC) after adjusting for RA area (RAA), tricuspid regurgitation (TR) grade, right ventricular (RV) global longitudinal strain (GLS), and pulmonary vascular resistance (PVR) (P = 0.006). Receiver operator characteristic (ROC) curve analysis indicated that RA LS < 22.9% was predictive of clinical worsening during follow-up (sensitivity = 80%; specificity = 87.9%; area under the curve (AUC) = 0.858), and the Kaplan-Meier curve confirmed that RA LS ≥ 22.9% was associated with more favorable long-term outcomes compared to RA LS < 22.9% (log-rank P < 0.01). On univariate Cox proportional hazards analysis, PVR, RVGLS, RAA, and RA LS were associated with long-term outcome, while RA LS was the only independent predictor in the multivariate analysis. Our findings suggest that RA LS measurements by speckle-tracking echocardiography (STE) can independently reflect the extent of right heart failure and predict clinical outcomes in patients with CTD-PAH. RA LS < 22.9% is associated with a higher risk of clinical worsening.

RESUMO

There are few data on the effects of low hemoglobine levels on the left atrium (LA) in anemic patients. Our aim was to evaluate left atrial (LA) volume and functions in anemic patients using real time three-dimensional echocardiography (RT3DE) and also to investigate changes in variables of LA after the correction of anemia. In total, 55 iron-deficiency anemia patients without traditional cardiovascular (CV) risk factors and 30 age- and gender-matched controls were studied. Assessments included history, physical examination and echocardiography. Of the 55 patients with anemia enrolled, 50 (39 females and 11 males 40.3 years) were followed and underwent echocardiography after correction of the anemia. LA maximum volume (LAVmax), LA minimal volume (LAVmin), LAVmax index (LAVI), before atrial contraction volume (LAVpreA), LA total emptying fraction, LA active emptying volume were higher in anemic patients. LA passive emptying fraction was significantly lower in anemic patients. Following correction of anemia, LA volume and function parameters were observed to be significantly reduced. Moreover, significant increase was noted in LA passive emptying fraction. Correlation analysis was performed and a significant negative correlation was noted between the percentage change in hemoglobin level and percentage change in LAVI (r = - 0.382, p = 0.003). It was shown that volume and functions of LA are impaired in anemic patients. However impaired parameters were improved after correction of anemia. It may be thought that RT3DE LA parameters can be used as an important preclinical marker of disease pathogenesis before developing heart failure or atrial arrhythmia.

RESUMO

BACKGROUND: Cryptogenic stroke, now defined as embolic stroke of undetermined source (ESUS), represents about a quarter of all ischemic strokes and the reoccurrence is high. Understanding this stroke subtype better would likely guide treatment recommendations. In this study, we tested the hypothesis that left atrial (LA) shape and function at rest, as well as with exercise, are abnormal compared to matched normal controls. METHODS: The study design was prospective enrollment of ESUS subjects who underwent measurement of LA function at rest and exercise by 2D and 3D echocardiograms. The exercise portion of the study was conducted using a ramped supine bicycle protocol during which LA function was measured. Stroke subjects were matched with normal subjects by age, gender, and body surface area. RESULTS: Over a 1-year enrollment period, 18 ESUS patients met inclusionary criteria and were studied. Their average age was 58 years old and 44% were female. ESUS subjects have larger LA end-diastolic volume at rest (14 versus 11 mL/m2, P = .04) and with exercise (11 versus 6 mL/m2, P = .001) compared to normal controls. In ESUS, there was a lack of response to maximal exercise of LA function as measured by the LA ejection fraction (61% versus 73% P = .001) and the LA function index (.68 versus .82, P = .02). The 3D analysis showed spherical remodeling of the LA in ESUS. This remodeling was documented by the sphericity index, which was increased in both diastole (.40 versus .32, P = .02) and systole (.63 versus .71 P = .03). CONCLUSIONS: In support of our hypothesis, we found that ESUS subjects have LA dysfunction and remodeling at rest and exercise in comparison to healthy, matched controls. Evaluation of the left atrium in this high-risk stroke subtype has potential to inform stroke prevention strategies and to suggest pathways for research.

RESUMO

Breast cancer radiotherapy has a clear benefit for both long-term survival and local recurrence rate. However, there is still much concern about the early radiation-induced heart toxicity. This article aimed to clarify the impact of certain cardiac biomarkers and strain echocardiographic imaging on the detection of early cardiac dysfunction. Several studies that reported changes in either echocardiographic and/or serum levels measurements after breast radiotherapy were searched. Despite the established role of cardiac biomarkers to predict late cardiotoxicity after radiotherapy, data concerning early cardiac damage are still lacking. Furthermore, although strain echocardiography represents a specific tool for the detection of cardiac morbidity in certain diseases, much interest concerns its role in the prediction of early heart failure after radiotherapy. Identification of new tools for the detection of early cardiotoxicity after breast radiotherapy may minimize the side-effects of therapeutic modalities in the clinical setting.

RESUMO

INTRODUCTION: Echinococcosis, also called hydatid disease, is a common parasitic infection of the liver. However, echinococcus lesions rarely involve the heart, especially in children. PATIENT CONCERNS: An 8-year-old child from grazing areas of northwest China was referred to our hospital for the complaint of inpersistent precordial chest pain and left upper quadrant pain for 3 years. Palpation showed hepatomegaly, abdominal palpable mass while inspection abdominal distension. Routine blood tests were within the normal ranges. DIAGNOSIS: Combining the life history in pasture area, imaging features and serology results, it was consistent with the diagnosis of cardiac echinococcosis. INTERVENTIONS: Surgery was performed to evacuate cyst liquid and remove the internal capsule of the cyst. OUTCOMES: There was no cystic lesion in heart on ultrasound and her physical condition improved significantly after the surgery. The patient died of hepatic hydatid cyst rupture due to refusing high-risk surgical treatment and other treatment. LESSONS: We presented a rare case of cystic echinococcosis involving left ventricle in a child, and surgery is an alternative and effective therapy for this lesion due to the cyst rupture or leakage that can result in anaphylaxis. The typical imaging features of the cardiac echinococcosis on cardiac magnetic resonance are presented. Patient prognosis relies on proper treatment of all lesions.

RESUMO

BACKGROUND: Finding of intracardiac lead masses in patients with cardiac implantable electronic devices remains controversial, as such masses have been observed in cases of exclusively local infections whereas they have not been recognized in patients with positive cultures of intravascular lead fragments. In this study, we aim to describe the prevalence of intracardiac lead masses in true asymptomatic patients with cardiac implantable electronic devices, to identify their predictive factors and to define their prognostic impact at long-term follow-up. METHODS: Seventy-eight consecutive patients admitted over a 6-month period for elective generator replacement without clinical evidence of infection were evaluated by transthoracic and transesophageal echocardiography and prospectively followed at in-clinic follow-up visits. RESULTS: Lead masses were found in 10 patients (12.8%). These patients had more frequently right ventricular dysfunction at univariate analysis (OR 2.71, P = 0.010) and after baseline variables adjustment (hazard ratio 6.25, P = 0.012). At 5-year follow-up without any specific therapy, none of the patients suffered from any cardiac device infections, or developed clinical signs of infections. CONCLUSION: There is an evidence of clinical lead masses in asymptomatic patients with cardiac implantable electronic devices. The value of these findings is still debated for aetiological interpretation and for therapeutic strategy, but they are not necessarily associated with an infection.

In case of atrial fibrillation, there is a higher risk of thrombus formation, which could affect the right heart as well. Visualization of the right atrial appendage is difficult; the aim of the present review was to demonstrate the role of routine echocardiographic techniques and to show related clinical data.

RESUMO

Transthoracic echocardiogram (TTE) is widely used as part of the work-up for ischemic stroke. However, the added utility of TTE in the management of small single subcortical infarcts (SSSI) has not been extensively evaluated. Therefore, we aimed to determine the frequency of high-risk and medium-risk cardioembolic sources diagnosed by TTE in SSSI patients, and whether the findings altered clinical management. We performed a retrospective analysis of a prospective cohort of patients with confirmed acute ischemic stroke enrolled in a single-center observational registry between August 2012 and July 2014. We assessed infarct topography on brain magnetic resonance imaging, blinded to final stroke subtype and treatment, to identify patients with SSSI. We defined SSSI as lesions in the corona radiata, basal ganglia, thalamus, or brainstem measuring <1.5 cm in maximal diameter. We excluded patients with atrial fibrillation and large artery stenosis >50%, and assessed the frequency of cardioembolic sources found by TTE in the remaining patients. Among 908 patients, 75 (8.3%) had SSSI, of which 4 (5.3%) had atrial fibrillation and 6 (8%) had symptomatic large artery stenosis. TTE revealed cardiac abnormalities in 46% of the remaining patients (mean age: 65.1 y, 52% female, 58% white). The most common findings were dilated left atrium (29%), patent foramen ovale (14%), and atrial septal aneurysm (7.7%). Anticoagulants were prescribed in 3 (4.6%) patients on the basis of TTE results. TTE identified potential cardioembolic sources in almost half of the patients, but altered antithrombotic management in only 5% of patients with SSSI.
