RESUMO

Abstract Objectives: Functional echocardiography is a valuable tool in the neonatal intensive care unit, but training programs are not standardized. The aim was to report an functional echocardiography training program for neonatologists and to describe the agreement of their measurements with the pediatric cardiologist. Methods: Functional echocardiography training lasted 32 h. After training program, the neonatologists performed functional echocardiography in the neonatal intensive care unit and were required to measure left cardiac chambers dimensions, left ventricle systolic function, right and left ventricular output, ductus arteriosus diameter, and flow pattern. Images were recorded by the equipment and reviewed offline by the pediatric cardiologist. The Bland-Altman test was used for quantitative variables and the kappa test, for qualitative variables. Results: Twenty-two trained neonatologists performed 100 functional echocardiography exams. Ductus arteriosus identification and flow pattern had substantial agreement (kappa = 0.91 and 0.88, respectively), as well as its diameter (mean difference = 0.04 mm). The mean difference for the aortic root was −1.2 mm; left atrium, 0.60 mm; left ventricle diastolic diameter, −0.90 mm; left ventricle systolic diameter, −0.30 mm. Shortening fraction and ejection fraction correlated well with broad limits of agreement, −2.96% (14.88; −20.82%) and −-3.43% (15.54; −22.40%), respectively. Right and left ventricular output had broad limits of agreement, 16.69 mL/kg/min (222.76; −189.37) and 23.57 mL/kg/min (157.88; −110), respectively. There was good agreement between interpretations of normal or low cardiac output (76.7% for right ventricular output; 75.7% for left ventricular output). Conclusion: This functional echocardiography training program enabled neonatologists to obtain adequate skills in performing the images, obtaining good agreement with the cardiologist in simple hemodynamic measurements and ductus arteriosus evaluation.


Resumo Objetivos: A ecocardiografia funcional é uma ferramenta valiosa na unidade de terapia intensiva neonatal, mas os programas de treinamento não são padronizados. Nosso objetivo foi relatar um programa de treinamento em ecocardiografia funcional para neonatologistas e descrever a concordância de suas medidas com o cardiologista pediátrico. Métodos: O treinamento em ecocardiografia funcional durou 32 horas. Após o programa de treinamento, os neonatologistas faziam ecocardiografia funcional na unidade de terapia intensiva neonatal e mediam as dimensões das câmaras cardíacas esquerdas, função sistólica do ventrículo esquerdo, débito cardíaco do ventrículo direito e débito cardíaco do ventrículo esquerdo, diâmetro do canal arterial e o padrão de fluxo. As imagens foram registradas no equipamento e revisadas offline pelo cardiologista pediátrico. O teste de Bland-Altman foi usado para variáveis quantitativas e o teste Kappa para variáveis qualitativas. Resultados: Foram feitas por 22 neonatologistas treinados 100 ecocardiografias funcionais. A identificação do canal arterial e o padrão de fluxo apresentaram concordância substancial (Kappa = 0,91 e 0,88, respectivamente), bem como seu diâmetro (diferença média = 0,04 mm). A diferença média foi de -1,2 mm para a raiz da aorta, 0,60 mm para o átrio esquerdo, -0,90 mm para o diâmetro diastólico do ventrículo esquerdo e de -0,30 mm para o diâmetro sistólico do ventrículo esquerdo. A fração de encurtamento e a fração de ejeção apresentaram boas correlações, com amplos limites de concordância, respectivamente -2,96% (14,88; -20,82%) e -3,43% (15,54; -22,40%). Os débitos cardíacos do ventrículo direito e do ventrículo esquerdo apresentaram amplos limites de concordância, 16,69 mL/kg/min (222,76; -189,37) e 23,57 mL/kg/min (157,88; -110), respectivamente. Houve boa concordância entre a interpretação de débito cardíaco normal ou baixo (76,7% de débito ventricular direito; 75,7% de débito ventricular esquerdo). Conclusão: Esse programa de treinamento em ecocardiografia funcional permitiu aos neonatologistas obter habilidades adequadas na realização das imagens, com boa concordância com o cardiologista em medidas hemodinâmicas simples e avaliação do canal arterial.

RESUMO

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.

RESUMO

AIMS: The Doppler-derived myocardial performance index (MPI) has been considered as a diagnostic and prognostic Doppler marker for many different clinical conditions. The purpose of this study was to determine the diagnostic accuracy of traditional Pulsed-wave Doppler (PWD-MPI) and Pulsed-wave tissue Doppler imaging (TDI-MPI) and the degree of agreement between these methods in patients with grade-I diastolic dysfunction (DDI) and a normal ejection fraction. METHODS: Forty-seven consecutive ambulatory patients with DDI were compared to 51 healthy subjects with normal echocardiograms. All subjects underwent measurement of time intervals and MPI with PWD and pulsed TDI. RESULTS: TDI-MPI and PWD-MPI were significantly higher in patients with DDI than in control subjects: 0.49 ± 0.14 vs. 0.40 ± 0.09 (P < 0.001) and 0.45 ± 0.11 vs. 0.37 ± 0.08 (P < 0.001), respectively. Cutoff values of TDI-MPI > 0.42 and PWD-MPI > 0.40 identified DDI subjects, with sensitivities of 74 and 64%; specificities of 61 and 69%; positive likelihood ratios of 1.9 and 2.0; and negative likelihood ratios of 0.42 and 0.53, respectively; no significant difference was noted between the areas under the ROC curves of TDI-MPI and PWD-MPI (P = 0.77). Bland-Altman plots showed wide limits of agreement between these indices: - 0.17 to 0.23 in healthy subjects and - 0.24 to 0.32 in DDI patients. CONCLUSION: PWD-MPI and TDI-MPI showed poor clinical agreement and were not reliable parameters for the assessment of left ventricular diastolic function.

RESUMO

OBJECTIVES: To evaluate cardiovascular involvement in children and adolescents with End Stage Renal Disease (ESRD) and to characterize the main risk factors associated with this outcome. METHODS: Cross-sectional study of 69 children and adolescents at renal transplantation and 33 healthy individuals matched by age and gender. The study outcomes were left ventricular mass z-score (LVMZ) and carotid artery intima-media thickness (CIMT). The potential risk factors considered were age, gender, CKD etiology, use of oral vitamin D and calcium-based phosphate binders, systolic and diastolic blood pressure, body mass index z-score, time since diagnosis, dialysis duration, serum levels of ionic calcium, phosphorus, parathyroid hormone, fibroblast growth factor (FGF 23), uric acid, homocysteine, cholesterol, triglycerides, C-reactive protein (CRP), vitamin D and hemoglobin. RESULTS: In the multivariate analysis, the factors associated with LVMZ were dialysis duration, age, systolic blood pressure, serum hemoglobin and HDL cholesterol levels. Regarding CIMT, in the multivariate analysis, systolic blood pressure was the only factor associated with the outcome. CONCLUSION: Children exhibited important cardiovascular involvement at the time of the renal transplantation. Both of the studied outcomes were independently associated with systolic blood pressure. For this reason, controlling blood pressure seems to be the main therapy to minimize cardiovascular involvement in children with ESRD.

RESUMO

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

RESUMO

BACKGROUND: The choice of a mechanical (MP) or biological prosthesis (BP) for patients with valvular heart disease undergoing replacement is still not a consensus. OBJECTIVE: We aimed to determine the clinical outcomes of MP or BP placement in those patients. METHODS: We conducted a systematic review and meta-analysis of randomized controlled trials (RCTs) that compared biological prostheses and mechanical prostheses in patients with valvular heart diseases and assessed the outcomes. RCTs were searched in the MEDLINE, EMBASE, LILACS, CENTRAL, SCOPUS and Web of Science (from inception to November 2014) databases. Meta-analyses were performed using inverse variance with random effects models. The GRADE system was used to rate the quality of the evidence. A P-value lower than 0.05 was considered significant. RESULTS: A total of four RCTs were included in the meta-analyses (1,528 patients) with follow up ranging from 2 to 20 years. Three used old generation mechanical and biological prostheses, and one used contemporary prostheses. No significant difference in mortality was found between BP and MP patients (risk ratio (RR = 1.07; 95% CI 0.99-1.15). The risk of bleeding was significantly lower in BP patients than MP patients (RR = 0.64; 95% CI 0.52-0.78); however, reoperations were significantly more frequent in BP patients (RR = 3.60; 95% CI 2.44-5.32). There were no statistically significant differences between BP and MP patients with respect to systemic arterial embolisms and infective endocarditis (RR = 0.93; 95% CI 0.66-1.31, RR = 1.21; CI95% 0.78-1.88, respectively). Results in the trials with modern and old prostheses were similar. CONCLUSIONS: The mortality rate and the risk of thromboembolic events and endocarditis were similar between BP and MP patients. The risk of bleeding was approximately one third lower for BP patients than for MP patients, while the risk of reoperations was more than three times higher for BP patients.

Resumo Fundamento: A escolha de próteses mecânicas ou biológicas para pacientes com doença de válvula cardíaca ainda não é um consenso. Objetivo: Determinar os desfechos clínicos de próteses mecânicas e biológicas nesses pacientes. Métodos: Conduzimos uma revisão sistemática e metanálise e estudos controlados randomizados (RCTs) que compararam próteses mecânicas e biológicas em pacientes com doenças de válvulas cardíaca, e avaliamos seus resultados. A busca por RCTs foi feita nas bases de dados MEDLINE, EMBASE, LILACS, CENTRAL, SCOPUS e Web of Science (do início a novembro de 2014). As metanálises foram realizadas usando variação inversa com modelos de efeitos aleatórios. Usamos o sistema GRADE para avaliar a qualidade da evidência. Um valor menor que 0,05 foi considerado significativo. Resultados: Um total de quatro RCTs foi incluído na metanálise (1528 pacientes) com acompanhamento de 2 a 20 anos. Em três estudos, foram utilizadas próteses mecânicas e biológicas mais antigas, e em um estudo próteses contemporâneas. Não foi observada diferença de mortalidade entre os pacientes que receberam próteses mecânicas e biológicas (risco relativo, RR = 1,07; IC95% 0,99-1,15). O risco de sangramento foi significativamente mais baixo nos pacientes que receberam próteses biológicas que naqueles com próteses mecânicas (RR = 0,64; IC95% 0,52-0,78). Contudo, as reoparações foram mais frequentes em pacientes com próteses biológicas (RR = 3,60; IC95% 2,44-5,32). Não houve diferenças estatisticamente significativas entre pacientes com próteses biológicas e mecânicas em relação à embolia arterial sistêmica e endocardite infecciosa (RR = 0,93; IC95% 0,66-1,31; RR = 1,21; IC95% 0,78-1,88, respectivamente). Resultados entre os estudos com próteses modernas e antigas foram similares. Conclusões: A taxa de mortalidade e o risco de eventos tromboembólicos e endocardite foram similares entre os pacientes que receberam próteses biológicas e mecânicas. O risco de sangramentos foi aproximadamente um terço menor nos pacientes com próteses biológicas que mecânicas, ao passo que o risco de reoperação foi mais que três vezes maior nos pacientes com próteses biológicas.

RESUMO

Right ventricular (RV) dysfunction harbingers adverse prognosis in pulmonary arterial hypertension (PAH). Although conventional two-dimensional echocardiography (2DE) is limited for RV systolic function quantitation, RV strain can be a useful tool. The diagnostic and prognostic impact of 2DE speckle-tracking RV longitudinal strain was evaluated, including other 2DE systolic indexes, in a group of PAH patients without severe impairment of functional capacity, chronic pulmonary thromboembolism or left ventricular dysfunction. Sixty-six group I PAH patients, 67 % NYHA functional class I or II (none in IV) were studied by 2DE to obtain: RV fractional area change, tricuspid annular plane systolic excursion, RV myocardial performance index, tissue Doppler tricuspid annulus systolic velocity. Global, free wall (RVFreeWSt) and septal RV longitudinal systolic strain were obtained. RV ejection fraction by cardiac magnetic resonance (CMR-RVEF) was also assessed. All patients were followed up to 3.9 years (mean 3.3 years). Combined endpoints were hospitalization for worsening PAH or cardiovascular death. Among all the 2DE indexes of RV systolic function, RVFreeWSt exhibited the best correlation with CMR-RVEF (r = 0.83; p < 0.005). Combined endpoints occurred in 15 (22.7 %) patients (6 hospitalizations and 9 deaths). Multivariate analysis identified RVFreeWSt ≤-14 % as the only 2DE independent variable associated with combined endpoints [HR 4.66 (1.25-17.37); p < 0.05]. We conclude that RVFreeWSt may be a suitable non-geometric 2DE surrogate of CMR-RVEF in PAH patients, constituting a powerful independent predictor of long-term outcome in this cohort with relatively preserved functional capacity.

RESUMO

Síntomas y lesiones articulares y neuromusculares (SLANM) pueden ocurrir por esfuerzo repetitivo, con elevada prevalencia en técnicos en ecocardiografía. La prevalencia de los SLANM diagnosticados aun es desconocida en ecocardiografistas brasileños. Objetivo:Evaluar la prevalencia de SLANM en cardiólogos brasileños relacionada al trabajo como ecocardiografistas. Métodos: Médicos asociados al Departamento de Imagen Cardiovascular fueron invitados a responder preguntas relacionadas al perfil antropométrico, de trabajo como ecocardiografista, y SLANM. La comparación entre los participantes con (grupo 1) y sin SLANM (grupo 2) fue hecha con el test t no pareado para variables continuas y con Chi-cuadrado para categóricas. Fueron considerados significativos valores de p <0,05. Resultados: De junio de 2014 a junio de 2015, 474 respondieron el cuestionario; de esos, 311 fueron válidos; 248 (80%) fueron del grupo1 (45 ± 9,2 años; 48% mujeres) y 63 (20%), del grupo 2 (43 ± 9,8 años; 29% mujeres). En el grupo 1, el tiempo medio de aparición de los SLANM fue de 6,8 ± 5,3 años a partir del entrenamiento como ecocardiografista; 144(58%) procuraron atención; 126 (88%) requirieron tratamiento; 51 (35%) necesitaron apartamiento temporal; y 5(4%), de cirugía. Los SLANM fueron más frecuentes en los hombros y en los profesionales con más de 10 años de trabajo como ecocardiografista (65%); en el grupo 2 había menos mujeres (p = 0,009). No hubo diferencia entre los grupos en relación a las medidas antropométricas, miembro superior utilizado para el examen (p = 0,25), número de exámenes por semana(p = 0,49), o práctica de actividades físicas(p = 0,91).Conclusión:La prevalencia de SLANM en ecocardiografistas brasileños parece ser elevada. Las mujeres y los profesionales con más de 10 años de ecocardiografía parecen más susceptible.


Introduction: Joint and neuromuscular injuries and symptoms (JNIS) may occur due to repetitive strain, with high prevalence in echocardiography technicians. The prevalence of diagnosed JNIS remains unknown in Brazilian echocardiographers. Objective: Evaluate the prevalence of JNIS in Brazilian cardiologists related to their work as echocardiographers. Methods: Physicians from the Department of Cardiovascular Imaging were asked to answer a questionnaire about their anthropometric profile, their work as echocardiographers, and JNIS. Participants with JNIS (group 1) and without JNIS (group 2) were analyzed as follows: a comparison of continuous variables was made by the unpaired t-test, and a comparison of categorical variables was made by a chi-square test. P values were considered significant if <0.05. Results: From June 2014 to June 2015, 474 answered the questionnaire; of these, 311 were valid; 248 (80%) were in group 1 (45 ± 9.2 years; 48%women) and 63 (20%) in group 2 (43 ± 9.8 years; 29% women). In group 1, the mean time to the onset of JNIS was 6.8 ± 5.3 years as from the start of echocardiography training; 144 (58%) sought care; 126 (88%) required treatment; 51 (35%) required temporary leave; and 5 (4%) underwentsurgery. JNIS were more common on shoulders and in professionals with more than 10 years working as echocardiographers (65%); group 2 had fewer women (p = 0.009). There was no difference between groups in relation to anthropometric measurements; test criteria: upper limb used for the exam(p = 0.25), number of exams per week (p = 0.49), or physical activity (p = 0.91). Conclusion: The prevalence of JNIS in Brazilian echocardiographers seems to be high. Women and professionals with over 10-years’ experience in echocardiography seem more susceptible.

RESUMO

Background:

Left atrial volume (LAV) is a predictor of prognosis in patients with heart failure.

Objective:

We aimed to evaluate the determinants of LAV in patients with dilated cardiomyopathy (DCM).

Methods:

Ninety patients with DCM and left ventricular (LV) ejection fraction ≤ 0.50 were included. LAV was measured with real-time three-dimensional echocardiography (eco3D). The variables evaluated were heart rate, systolic blood pressure, LV end-diastolic volume and end-systolic volume and ejection fraction (eco3D), mitral inflow E wave, tissue Doppler e´ wave, E/e´ ratio, intraventricular dyssynchrony, 3D dyssynchrony index and mitral regurgitation vena contracta. Pearson´s coefficient was used to identify the correlation of the LAV with the assessed variables. A multiple linear regression model was developed that included LAV as the dependent variable and the variables correlated with it as the predictive variables.

Results:

Mean age was 52 ± 11 years-old, LV ejection fraction: 31.5 ± 8.0% (16-50%) and LAV: 39.2±15.7 ml/m2. The variables that correlated with the LAV were LV end-diastolic volume (r = 0.38; p < 0.01), LV end-systolic volume (r = 0.43; p < 0.001), LV ejection fraction (r = -0.36; p < 0.01), E wave (r = 0.50; p < 0.01), E/e´ ratio (r = 0.51; p < 0.01) and mitral regurgitation (r = 0.53; p < 0.01). A multivariate analysis identified the E/e´ ratio (p = 0.02) and mitral regurgitation (p = 0.02) as the only independent variables associated with LAV increase.

Conclusion:

The LAV is independently determined by LV filling pressures (E/e´ ratio) and mitral regurgitation in DCM.

Fundamento:

O Volume do Átrio Esquerdo (VAE) é preditor prognóstico em pacientes com insuficiência cardíaca.

Objetivo:

O objetivo do estudo foi avaliar os determinantes do VAE em pacientes com Cardiomiopatia Dilatada (CMD).

Métodos:

Incluídos 90 pacientes com CMD e fração de ejeção do Ventrículo Esquerdo (VE) ≤ 0,50. O VAE foi medido pela ecocardiografia tridimensional (eco3D). Foram avaliados frequência cardíaca, pressão arterial sistólica, volume diastólico e sistólico final do VE, fração de ejeção do VE, onda E mitral, onda e´ do anel mitral (Doppler tecidual), relação E/e´, dissincronia intraventricular, índice de dissincronia tridimensional e insuficiência mitral. O coeficiente de correlação de Pearson analisou a correlação do VAE com as variáveis avaliadas e a regressão linear múltipla as variáveis independentes associadas ao VAE.

Resultados:

A idade média foi 53 ± 11 anos, fração de ejeção do VE: 31,5 ± 8,0% e VAE: 39,2 ± 15,7 ml/m2. As variáveis que se correlacionaram com o VAE foram: volume diastólico final do VE (r = 0,38; p < 0,01), volume sistólico final do VE (r = 0,43; p < 0,001), fração de ejeção do VE (r = -0,36; p v 0,01), onda E (r = 0,50; p < 0,01), relação E/e´ (r = 0,51; p < 0,01) e insuficiência mitral (r = 0,53; p < 0,01). A análise multivariada identificou relação E/e´ (p = 0,02) e insuficiência mitral (p = 0,02) como os únicos preditores independentes do aumento do VAE.

Conclusão:

O VAE na CMD é determinado independentemente pelas pressões de enchimento do VE (relação E/e´) e insuficiência mitral.

The variables evaluated were heart rate, systolic blood pressure, LV end-diastolic volume and end-systolic volume and ejection fraction (eco3D), mitral inflow E wave, tissue Doppler e' wave, E/e' ratio, intraventricular dyssynchrony, 3D dyssynchrony index and mitral regurgitation vena contracta. Pearson's coefficient was used to identify the correlation of the LAV with the assessed variables. A multiple linear regression model was developed that included LAV as the dependent variable and the variables correlated with it as the predictive variables.

RESUMO

BACKGROUND: Left atrial (LA) dilation is associated with worse prognosis in various clinical situations including chronic mitral regurgitation (MR). Real time three-dimensional echocardiography (3DE) has allowed a better assessment of LA volumes and function. Little is known about LA size and function in early postoperative period in symptomatic patients with chronic organic MR. We aimed to investigate these aspects. METHODS: By means of 3DE, 43 patients with symptomatic chronic organic MR were prospectively studied before and 30 days after surgery (repair or bioprosthetic valve replacement). Twenty subjects were studied as controls. Maximum (Vol-max), minimum, and preatrial contraction LA volumes were measured and total, passive, and active LA emptying fractions were calculated. RESULTS: Before surgery patients had higher LA volumes (P < 0.001) but smaller LA emptying fractions than controls (P < 0.01). After surgery there was a reduction in all 3 LA volumes and an increase in active atrial emptying fraction (AAEF). Multivariate analysis showed that independent predictors of early postoperative Vol-max reduction were preoperative diastolic blood pressure (coefficient = -0.004; P = 0.02), lateral mitral annular early diastolic velocity (e') (coefficient = 0.023; P = 0.008), and the mean transmitral diastolic gradient increment (coefficient = -0.035; P < 0.001). Furthermore, e' was also independently associated with AAEF increase (odds ratio = 1.66, P = 0.027). CONCLUSION: Early LA reverse remodeling and functional improvement occur after successful surgery of symptomatic organic MR regardless of surgical technique. Diastolic blood pressure and transmitral mean gradient augmentation are variables negatively related to Vol-max reduction. Besides, e' is positively correlated with both Vol-max reduction and AAEF increase.
