Valores de referência de parâmetros ecocardiográficos estruturais e funcionais para a população brasileira: avaliação de câmaras direitas - estudo de normais - DIC / Reference values ​​of structural and functional echocardiographic parameters for the Brazilian population: evaluation of right chambers - study of normals - DIC

INTRODUÇÃO: A avaliação e quantificação das dimensões e função das câmaras cardíacas direitas pelo ecocardiograma auxilia no diagnóstico e prognóstico de várias situações clinicas; seus valores de referência, no entanto, refletem as características antropométricas da população estudada. OBJETIVO: analisar prospectivamente exames ecocardiográficos bidimensionais de indivíduos normais das diversas regiões brasileiras para a determinação de valores de referência de câmaras direitas. MÉTODO: Ecocardiogramas de indivíduos de ambos sexos, > 18 anos, sem doença cardíaca, sistêmica ou fatores de risco cardiovascular foram obtidos em centros das 5 regiões do Brasil e analisados offline (Ultrasound Workspace- Tomtec- Phillips) para avaliação de medidas das câmaras cardíacas direitas e função ventricular direita (VD): variação fracional da área (FAC) do VD, TAPSE, s­ do VD e strain longitudinal (SL) do VD (global e parede livre) por speckle tracking. Foram analisadas as diferenças entre os sexos pelo teste t não pareado de Student. RESULTADOS: Foram incluídos 445 indivíduos, com idade de 42+ 15 anos, 56% do sexo feminino, sendo excluídos 40 por imagem/dados inadequados; As medidas ecocardiográficas foram realizadas em 147 indivíduos e mostraram maiores dimensões de câmaras direitas para o sexo masculino (p<0.001); para parâmetros funcionais, apenas o FAC mostrou diferença significativa entre os grupos, sendo maior para o sexo feminino (p = 0.04); os demais parâmetros funcionais ( TAPSE, S­ VD, e SGL e de parede livre do VD) foram similares para ambos os sexos . CONCLUSÃO: Resultados preliminares da população brasileira sugerem parâmetros estruturais com maiores dimensões de câmaras direitas para o sexo masculino, o que infere que esses dados devam ser indexados para a superfície corpórea. Parâmetros funcionais, por outro lado, parecem sofrer pouca influência do sexo.

Zero-contrast imaging for the assessment of transcatheter aortic valve implantation in candidates with renal dysfunction.

BACKGROUND: Candidates for transcatheter aortic valve implantation (TAVI) are currently evaluated using computed tomography angiography and invasive cardiac catheterization as an essential part of case selection and pre-procedure interventional planning. However, both imaging methods utilize iodinated agents, which may cause contrast-induced nephropathy, particularly in patients with baseline renal dysfunction. This study aimed to describe a zero-contrast imaging protocol for pre-TAVI evaluation in patients with advanced renal impairment. METHODS: The pre-TAVI zero-contrast scheme consisted of the following multi-modality combinations: (1) gadolinium-free magnetic resonance imaging (three-dimensional navigator-echo with electrocardiogram-gated steady-state free-precession series); (2) iodinated-free multislice computed tomography electrocardiogram-gated; (3) lower limb arterial duplex scan ultrasound; and (4) transesophageal echocardiography. Ultimately, TAVI was performed for those deemed good candidates, and contrast was allowed during the intervention; however, operators were strongly advised to utilize the least volume possible of iodinated agents. This pilot survey included ten patients with symptomatic aortic stenosis and renal dysfunction who underwent zero-contrast multi-modality imaging. RESULTS: All the patients ultimately underwent TAVI. The intervention was successful in all cases, without ≥ moderate residual aortic regurgitation, prosthesis embolization, annulus rupture, major vascular complications, stroke, or death during index hospitalization. The creatinine clearance remained stable throughout the observation period (baseline: 26.85 ± 12.55 mL/min; after multi-modality imaging: 26.76 ± 11.51 mL/min; post-TAVI at discharge: 29.84 ± 13.98 mL/min; p = 0.3 all). CONCLUSION: The proposed contrast-free imaging protocol appears to be a promising clinical tool for pre-TAVI evaluation in patients with severe renal dysfunction.

Three-dimensional transesophageal echocardiographic evaluation of aortic plaque after cerebrovascular event.

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. METHODS: Patients within one week of a stroke (confirmed by brain computed tomography/magnetic resonance) underwent TEE and 3D findings were compared with two-dimensional (2D) (aorta plaque number, dimensions, area and the presence of debris and ulcerations). Patients were followed for two years for death or a new stroke. RESULTS: We assessed 78 patients, 43 (55%) male, aged 62±14 years old, 92% in sinus rhythm. Aortic atheroma was found mainly in the descending aorta (50%); plaque thickness was similar for 2D TEE (0.29±0.03 cm) and 3D TEE (0.29±0.04 cm), whereas plaque area was slightly increased for 3D measurements (0.24±0.02 cm2 versus 0.37±0.03 cm2 respectively, p<0.05), with a strong correlation found both for aortic plaque thickness (r=0.91) and area (r=0.80) measurements. While aortic debris were equally seen with both techniques, 3D TEE defines the presence of ulcerations (six ulcerations unseen with 2D TEE better, p=0.03). There were 11 events (six deaths and five new strokes) during follow-up, unrelated to plaque characteristics. CONCLUSION: To evaluate aortic plaque morphology, 3D TEE is superior to 2D TEE due to improved detection of ulcerated aortic plaque; this might provide additional information in patients after ischemic stroke.

Evaluation of the myocardial deformation in the diagnosis of rejection after heart transplantation.

Introduction: Heart transplantation represents main therapy for end-stage heart failure. However, survival after transplantation is limited by development of graft rejection. Endomyocardial biopsy, an invasive and expensive procedure, is gold standard technique for diagnosis of rejection. Most of biopsy complications are observed using echocardiography. Novel echocardiographic techniques, such as myocardial strain and three-dimensional reconstruction, can be useful in heart transplant patients. Purpose: To evaluate ventricular strain in heart transplant patients and association with rejection, cellular or humoral, as well as two- and three-dimensional echocardiographic parameters. Methods: Cohort of patients from heart transplant program taken to echocardiography after endomyocardial biopsy, from December 2017 to January 2020. Ventricular strain and three-dimensional left ventricle parameters were studied. Rejection results were retrieved from medical record. Qualitative variables were expressed by absolute frequency and percentages, while continuous variables by means and standard deviations. Association between rejection and variables of interest was measured by odds ratio and confidence interval of 95%, with p-value < 0.05. Results: 123 post-endomyocardial biopsy echocardiographic exams were performed in 54 patients. Eighteen exams were excluded, lasting 105 exams to be evaluated for conventional and advanced echocardiographic parameters. Male patients were 60.4%. Prevalence of cellular rejection was 8.6%, humoral rejection 12.4%, and rejection of any type 20%. There was no association between right ventricular strain and rejection, whether cellular (p = 0.118 and p = 0.227 for septum and free wall, respectively), humoral (p = 0.845 and p = 0.283, respectively), or of any type (0.504 and 0.446). There was no correlation between rejection and left ventricle global longitudinal strain, three-dimensional ejection fraction or desynchrony index. Conventional parameters associated to rejection were left ventricle posterior wall thickness [OR 1.660 (1.163; 2.370), p = 0.005] and left ventricle mass index [OR 1.027 (1.011; 1.139), p = 0.001]. Left ventricle posterior wall thickness remained significant after analysis of cellular and humoral rejection separately [OR 1.825 (1.097; 3.036), p = 0.021 and OR 1.650 (1.028; 2.648), p = 0.038, respectively]. Conclusions: There was no association between ventricular strain, three-dimensional left ventricular ejection fraction and the desynchrony index and rejection, cellular or humoral. Evidence of association of graft rejection with left ventricle posterior wall thickness and left ventricle mass index was observed.

Early Change in Area Strain Detected by 3D Speckle Tracking Is Associated With Subsequent Cardiotoxicity in Patients Treated With Low Doses of Anthracyclines.

Objective: To evaluate the prognostic impact of the parameters of myocardial deformation using three-dimensional speckle tracking echocardiography (3DSTE) in patients with breast cancer who underwent chemotherapy with low doses of anthracyclines. Background: Chemotherapy-related cardiotoxicity has an important prognostic impact on cancer survivors. Three-dimensional STE has revealed more consistent data than two-dimensional techniques and may represent a more accurate tool in the evaluation of myocardial function in patients who underwent chemotherapy. Methods: We evaluated patients with breast cancer who were treated with anthracyclines (associated or not with trastuzumab) in five stages: baseline, after cumulative doses of 120 and 240 mg/m2 of doxorubicin, and then, after 6 months and at least 1 year after anthracyclines. Ultrasensitive troponin I (US-TnI) and a standard echocardiography study were performed at each stage. We analyzed left ventricular ejection fraction (LVEF) by Simpson's method, two-dimensional speckle tracking (2DSTE) with longitudinal and radial strain values, and 3DSTE with longitudinal, radial, and circumferential strain as well as twist, torsion, rotation, and three-dimensional global area strain (3DGAS). Cardiotoxicity was defined as a decrease in LVEF by more than 10 percentage points to a value lower than 53%. Results: We evaluated 51 female patients who were aged 50.6 ± 11 years. After the cumulative dose of 240 mg/m2 of doxorubicin, US-TnI was increased (>34 pg/ml) in 21 patients (45%, p > 0.001), LVEF remained unchanged (p = 0.178), while 2DSTE longitudinal strain was decreased (from -17.8% to -17.1%, p < 0.001) and 3DSTE detected changes in longitudinal, radial, circumferential, and area strain. After a lower cumulative dose of doxorubicin (120 mg/m2), 3DGAS (p < 0.001) was the only parameter that was changed. In the follow-up, 7 (13%) patients presented a decrease in LVEF. Three-dimensional GAS early changed to abnormal values was the only variable associated with a subsequent decrease in LVEF (definitive cardiotoxicity). Conclusion: In patients with breast cancer, 3DSTE detected early changes in area strain after very low doses of doxorubicin. The 3DGAS early changed to abnormal values was associated with a subsequent decrease in LVEF, representing a promising technique to predict chemotherapy-induced cardiomyopathy.

A risk score for predicting death in COVID-19 in-hospital infection: A Brazilian single-center study.

BACKGROUND: There is a paucity of information about Brazilian COVID-19 in-hospital mortality probability of death combining risk factors. 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. We analyzed the data from 111 patients from March to August 2020, performed a complete transthoracic echocardiogram, chest thoracic tomographic (CT) studies, collected biomarkers and correlated to in-hospital mortality. RESULTS: Mean age of the patients: 67 ± 17 years old, 65 (58.5%) men, 29 (26%) presented with systemic arterial hypertension, 18 (16%) with diabetes, 11 (9.9%) with chronic obstructive pulmonary disease. There was need for intubation and mechanical ventilation of 48 (43%) patients, death occurred in 21/111 (18.9%) patients. Multiple logistic regression models correlated variables with mortality: age (OR: 1.07; 95% CI 1.02-1.12; p: 0.012; age >74 YO AUC ROC curve: 0.725), intubation need (OR: 23.35; 95% CI 4.39-124.36; p < 0.001), D dimer (OR: 1.39; 95% CI 1.02-1.89; p: 0.036; value >1928.5 ug/L AUC ROC curve: 0.731), C-reactive protein (OR: 1.18; 95% CI 1.05-1.32; p < 0.005; value >29.35 mg/dl AUC ROC curve: 0.836). A risk score was created to predict intrahospital probability of death, by the equation: 3.6 (age >75 YO) + 66 (intubation need) + 28 (C-reactive protein >29) + 2.2 (D dimer >1900). CONCLUSIONS: A novel and original risk score were developed to predict the probability of death in Covid 19 in-hospital patients concerning combined risk factors.

In-hospital COVID-19 infection echocardiographic analysis: a Brazilian, tertiary single-centre experience.

BACKGROUND: Information is lacking concerning in-hospital echocardiography analysis of COVID-19 infection in Brazil. We evaluated echocardiographic parameters to predict a composite endpoint of mortality, pulmonary thromboembolism or acute renal failure. METHODS: A prospective full echocardiographic study of consecutive patients hospitalized with COVID-19, single tertiary centre in Brazil. We correlated echocardiographic findings to biomarkers, clinical information, thoracic tomography, and in-hospital composite endpoint of mortality, pulmonary thromboembolism or renal failure. RESULTS: One hundred eleven patients from March to October 2020, 67 ± 17 years, 65 (58.5%) men, death was observed in 21/111 (18.9%) patients, 48 (43%) required mechanical ventilation, myocardial infarction occurred in 10 (9%), pulmonary thromboembolism in 7 (6.3%) patients, haemodialysis was required for 9 (9.8%). Echocardiography was normal in 51 (46%) patients, 20 (18%) presented with decreased left ventricle ejection, 18 (16.2%) had abnormal left ventricle global longitudinal strain, 35 (31%) had diastolic dysfunction, 6 (5.4%) had an E/e'ratio > 14, 19 (17.1%) presented with right ventricle dilated/dysfunction, 31 (28%) had pericardial effusion. The echocardiographic parameters did not correlate with mortality, biomarkers, clinical events. Tricuspid velocity was related to the composite endpoint of mortality, pulmonary thromboembolism or acute renal failure (p: 00.3; value: 2.65 m/s; AUC ROC curve: 0.739; sensitivity: 73.3; specificity: 66.7; CI: 0.95, inferior: 0.613; superior: 0,866). CONCLUSIONS: Among hospitalized patients with COVID-19, echocardiography was normal in 51(46%) patients, and 20 (18%) patients presented with a decreased left ventricle ejection fraction. Tricuspid velocity was related to the composite endpoint of mortality, pulmonary thromboembolism or acute renal failure.

Right Ventricular Systolic Function After the Cone Procedure for Ebstein's Anomaly: Comparison Between Echocardiography and Cardiac Magnetic Resonance.

Although the Cone procedure has improved outcomes for patients with Ebstein´s anomaly (EA), neither RV systolic function recovery in long-term follow-up nor the best echocardiographic parameters to assess RV function are well established. Thus, we evaluated RV performance after the Cone procedure comparing two-dimensional (2DEcho) and three-dimensional (3DEcho) echocardiography to cardiac magnetic resonance (CMR). We assessed 27 EA patients after the Cone procedure (53% female, median age of 20 years at the procedure, median post-operative follow-up duration of 8 years). Echocardiography was performed 4 h apart from the CMR. RV global longitudinal strain (GLS), fractional area change (FAC), tricuspid annular plane systolic excursion (TAPSE), myocardial performance index and tissue Doppler S' velocity were assessed using 2DEcho, whereas 3DEcho was used to evaluate RV volumes and ejection fraction (RVEF). Echocardiographic variables were compared to CMR-RVEF. All patients were in the NYHA functional class I. Median TAPSE was 15.9 mm, FAC 30.2%, and RV-GLS -15%; median RVEF by 3DEcho was 31.9% and 43% by CMR. Among 2DEcho parameters, RV-GLS and FAC had a substantial correlation with CMR-RVEF (r = - 0.63 and r = 0.55, respectively); from 3DEcho, the indexed RV volumes and RVEF were closely correlated with CMR (RV-EDVi, r = 0.60, RV-ESVi, r = 0.72; and RVEF r = 0.60). RV systolic function is impaired years after the Cone procedure, despite a good clinical status. FAC and RV-GLS are useful 2DEcho tools to assess RV function in these patients; however, 3DEcho measurements appear to provide a better RV assessment.

Value of Contrast Transesophageal Echocardiography in the Detection of Intrapulmonary Vascular Dilatations in Hepatosplenic Schistosomiasis / Valor do Ecocardiograma Transesofágico com Contraste no Diagnóstico da Dilatação Vascular Intrapulmonar na Esquistossomose Hepatoesplênica

Abstract Background: Hepatopulmonary syndrome (HPS), found in cirrhotic patients, has been little studied in hepatosplenic schistosomiasis (HSS) and includes the occurrence of intrapulmonary vascular dilatations (IPVD). Contrast transesophageal echocardiography (cTEE) with microbubbles is more sensitive than contrast transthoracic echocardiography (cTTE) with microbubbles in the detection of IPVD in cirrhosis. Objective: To assess the performance of the cTEE, compared with that of cTTE, in detecting IPVD for the diagnosis of HPS in patients with HSS. Methods: cTEE and cTTE for investigation of IPVD and laboratory tests were performed in 22 patients with HSS. Agitated saline solution was injected in peripheral vein during the cTEE and cTTE procedures. Late appearance of the microbubbles in the left chambers indicated the presence of IPVD. Results of the two methods were compared by the Student's t-test and the chi-square test (p < 0.05). Results: cTEE was performed in all patients without complications. Three patients were excluded due to the presence of patent foramen ovale (PFO). The presence of IPVD was confirmed in 13 (68%) of 19 patients according to the cTEE and in only six (32%, p < 0.01) according to the cTTE. No significant differences in clinical or laboratory data were found between the groups with and without IPVD, including the alveolar-arterial gradient. The diagnosis of HPS (presence of IPVD with changes in the arterial blood gas analysis) was made in five patients by the cTEE and in only one by the cTTE (p = 0.09). Conclusion: In HSS patients, cTEE was safe and superior to cTTE in detecting IPVD and allowed the exclusion of PFO.

Resumo Fundamento: A síndrome hepatopulmonar (SHP), presente em pacientes cirróticos, é pouco estudada na esquistossomose hepatoesplênica (EHE) e inclui a ocorrência de dilatações vasculares intrapulmonares (DVP). O ecocardiograma transesofágico com contraste (ETEc) de microbolhas é mais sensível que o ecocardiograma transtorácico com contraste (ETTc) de microbolhas na identificação de DVP na cirrose. Objetivo: Avaliar o desempenho do ETEc comparado ao ETTc na identificação de DVP para diagnóstico de SHP em pacientes com EHE. Métodos: Incluímos 22 pacientes com EHE submetidos a ETEc e ETTc para pesquisa de DVP, além de exames laboratoriais. Os ETEc e ETTc foram realizados empregando-se solução salina agitada, injetada em veia periférica. A visualização tardia das microbolhas em câmaras esquerdas indicava presença de DVP. Os resultados foram comparados entre os dois métodos pelos testes t de Stu dent e qui-quadrado (significância p < 0,05). Resultados: Todos os 22 pacientes realizaram ETEc sem intercorrências. Foram excluídos três pela presença de forame oval patente (FOP), e a análise final foi realizada nos outros 19. A DVP esteve presente ao ETEc em 13 pacientes (68%) e em apenas seis ao ETTc (32%, p < 0,01). Não houve diferenças significativas nos dados clínicos e laboratoriais entre os grupos com e sem DVP, incluindo a diferença alveoloarterial de oxigênio. O diagnóstico de SHP (presença de DVP com alterações gasométricas) ocorreu em cinco pacientes pelo ETEc e em apenas um pelo ETTc (p = 0,09). Conclusão: Em pacientes com EHE, o ETEc foi seguro e superior ao ETTc na detecção de DVP não identificada ao ETTc, o que possibilitou adicionalmente excluir FOP.

Risco de infecção associado ao exame de ecocardiografia transesofágica e medidas de prevenção: revisão de literatura / Risk of infection associated with transesophageal echocardiography and prevention measures: literature review

Introdução: O ecocardiograma transesofágico é um exame amplamente utilizado na prática clínica para investigação e diagnóstico de doenças cardíacas e não cardíacas. Apesar de seguro, trata-se de exame semi-invasivo e não isento de ris-cos. Casos de infecção associados ao ecocardiograma tran-sesofágico foram descritos e, devido ao potencial risco de transmissão de infecção durante sua realização, o objetivo deste trabalho foi revisar dados da literatura referentes à transmissão de infecção durante a realização do exame, bem como os métodos de prevenção. Métodos: Revisão de literatura sobre o tema realizada entre dezembro de 2017 e janeiro de 2018, por meio de pesquisa em portais científicos de domínio público, nas diferentes bases de dados de ciências da saúde, que incluíram artigos originais, diretrizes, revisões simples e sistemática, e relatos de casos, publicados em periódicos indexados nos últimos 20 anos. Resultados: Preencheram os critérios estabelecidos 13 artigos: uma re-visão sistemática sobre complicações associadas ao ecocar-diograma transesofágico, seis artigos que descreveram surtos bacterianos relacionados ao ecocardiograma transesofágico, a diretriz britânica sobre limpeza e desinfecção para sondas de ecocardiografia transesofágica, quatro artigos sobre reações adversas a resíduos de ortoftaldeído em sondas de ecocardiograma transesofágico e um artigo referente ao uso de capas protetoras para as sondas. Conclusão: O risco de infecção associado ao ecocardiograma transesofágico existe, apesar de pouco descrito na literatura. É recomendado o es-tabelecimento de protocolos específicos de desinfecção das sondas de ecocardiograma transesofágico e inspeção rotinei-ra das sondas. O fortalecimento das equipes de controle de infecção também é essencial para a detecção e a resolução de surtos relacionados ao ecocardiograma transesofágico
