ABSTRACT

Abstract We report a case of a 59-year-old female patient with vegetative native mitral valve endocarditis caused by Stenotrophomonas maltophilia (SM). She had hemodialysis-dependent chronic renal failure, but no immunosuppressive disease. Echocardiography showed mobile vegetation on her native mitral valve. Right femoral artery embolectomy and mitral valve replacement were performed simultaneously. She awakened from anesthesia, but she passed away due to septic shock complications. To the best of our knowledge, this was the first case in whom native mitral valve endocarditis caused by SM was observed (despite of absence of any immunosuppressive event) and needed to undergo valve replacement.

ABSTRACT

Abstract Introduction: Metabolic syndrome (MetS) is defined as an association between diabetes, hypertension, obesity and dyslipidemia and an increased risk of cardiovascular disease. Mitral annular calcification (MAC) is associated with several cardiovascular disorders, including coronary artery disease, atrial fibrillation (AF), heart failure, ischemic stroke and increased mortality. The CHA2DS2-VASc score is used to estimate thromboembolic risk in AF. However, the association among MAC, MetS and thromboembolic risk is unknown and was evaluated in the current study. Methods: The study group consisted of 94 patients with MAC and 86 patients with MetS. Patients were divided into two groups: those with and those without MAC. Results: Patients with MAC had a higher MetS rate (P<0.001). In patients with MAC, the CHA2DS2-VASc scores and the rate of cerebrovascular accident and AF were significantly higher compared to those without MAC (P<0.001, for both parameters). The results of the multivariate regression analysis showed that history of smoking, presence of MetS and high CHA2DS2-VASc scores were associated with the development of MAC. ROC curve analyses showed that CHA2DS2-VASc scores were significant predictors for MAC (C-statistic: 0.78; 95% CI: 0.706-0.855, P<0.001). Correlation analysis indicated that MAC was positively correlated with the presence of MetS and CHA2DS2-VASc score (P=0.001, r=0.264; P<0.001, r=0.490). Conclusion: We have shown that CHA2DS2-VASc score and presence of MetS rates were significantly higher in patients with MAC compared without MAC. Presence of MAC was correlated with CHA2DS2-VASc score, presence of MetS, AF and left atrial diameter and negatively correlated with left ventricular ejection fraction.

ABSTRACT

Embolic stroke secondary to cardiac tumors is uncommon. However, 25-30% of cardiac tumors may cause systemic emboli. We report a 29-year-old male consulting for a sudden episode of aphasia and right hemiparesis, compatible with infarct of the left middle cerebral artery territory. Transthoracic echocardiography reported an ovoid tumor of 8 × 7 × 7 mm in relation to the sub valvular apparatus of the mitral valve. After neurologic stabilization, surgical treatment was performed. Approached by median sternotomy and in cardiopulmonary bypass, the mitral valve was explored. A macroscopic tumor consistent with a papillary fibroelastoma curled in sub valvular chordae was found. It was deployed and resected from its base, while the anterior mitral leaflet was preserved intact. Histopathological examination confirmed the intraoperative macroscopic diagnosis. The patient recovered uneventfully postoperatively and was discharged on the fifth day after surgery. He currently is in functional capacity I without cardiovascular symptoms at five years follow-up.

ABSTRACT

Abstract Background: The prevalence of coronary artery disease (CAD) in valvular patients is similar to that of the general population, with the usual association with traditional risk factors. Nevertheless, the search for obstructive CAD is more aggressive in the preoperative period of patients with valvular heart disease, resulting in the indication of invasive coronary angiography (ICA) to almost all adult patients, because it is believed that coronary artery bypass surgery should be associated with valve replacement. Objectives: To evaluate the prevalence of obstructive CAD and factors associated with it in adult candidates for primary heart valve surgery between 2001 and 2014 at the National Institute of Cardiology (INC) and, thus, derive and validate a predictive obstructive CAD score. Methods: Cross-sectional study evaluating 2898 patients with indication for heart surgery of any etiology. Of those, 712 patients, who had valvular heart disease and underwent ICA in the 12 months prior to surgery, were included. The P value < 0.05 was adopted as statistical significance. Results: The prevalence of obstructive CAD was 20%. A predictive model of obstructive CAD was created from multivariate logistic regression, using the variables age, chest pain, family history of CAD, systemic arterial hypertension, diabetes mellitus, dyslipidemia, smoking, and male gender. The model showed excellent correlation and calibration (R² = 0.98), as well as excellent accuracy (ROC of 0.848; 95%CI: 0.817-0.879) and validation (ROC of 0.877; 95%CI: 0.830 - 0.923) in different valve populations. Conclusions: Obstructive CAD can be estimated from clinical data of adult candidates for valve repair surgery, using a simple, accurate and validated score, easy to apply in clinical practice, which may contribute to changes in the preoperative strategy of acquired heart valve surgery in patients with a lower probability of obstructive disease.


Resumo Fundamento: A prevalência de doença arterial coronariana (DAC) nos pacientes valvares é semelhante à da população geral, com associação usual aos fatores de risco tradicionais. Ainda assim, a busca por DAC obstrutiva é mais agressiva nos valvulopatas em pré-operatório, determinando a angiografia coronariana invasiva (ACI) a praticamente todos os pacientes adultos, uma vez que se acredita que a cirurgia de revascularização miocárdica deva ser associada à troca valvar. Objetivos: Avaliar a prevalência de DAC obstrutiva e identificar fatores a ela associados em adultos candidatos à cirurgia cardíaca primariamente valvar entre os anos de 2001 a 2014 no Instituto Nacional de Cardiologia (INC) e elaborar um modelo preditivo de DAC obstrutiva através de escore derivado de análise multivariada. A partir da estimativa da probabilidade pré-teste de DAC obstrutiva, espera-se melhor estratégia pré-operatória para cada paciente. Métodos: Estudo transversal avaliando 2.898 pacientes com indicação de cirurgia cardíaca por qualquer etiologia. Desses, foram estudados 712 pacientes valvopatas submetidos à ACI nos 12 meses anteriores à cirurgia. Diferenças com valor de p < 0,05 foram consideradas estatisticamente significativas. Resultados: A prevalência de DAC obstrutiva foi de 20%. Um modelo preditivo de DAC obstrutiva foi criado a partir de regressão logística multivariada, utilizando as variáveis idade, dor torácica, história familiar de DAC, hipertensão arterial sistêmica, diabetes mellitus, dislipidemia, tabagismo e sexo masculino. O modelo demonstrou excelente correlação e calibração (R2 = 0,98), além de ótima acurácia (ROC de 0,848; IC95% 0,817 - 0,879) e validação em diferente população valvar (ROC de 0,877; IC 95%: 0,830 - 0,923). Conclusões: É possível estimar DAC obstrutiva a partir de dados clínicos com elevada acurácia, o que pode vir a permitir estabelecer estratégias pré-operatórias de acordo com a probabilidade pré-teste individual, evitando a indicação indiscriminada de procedimentos desnecessários e invasivos, principalmente nos grupos de menor probabilidade de DAC obstrutiva.

ABSTRACT

Se llevó a cabo un estudio observacional, descriptivo y transversal de 51 pacientes portadores de prótesis valvulares, ingresados en el Cardiocentro del Hospital Provincial Docente Clinicoquirúrgico Saturnino Lora Torres de Santiago de Cuba por presentar trombosis valvular o episodios hemorrágicos, desde enero del 2012 hasta diciembre del 2014, a fin de estimar las variaciones en los valores de la Razón Normalizada Internacional y su asociación con estos eventos. Se aplicó la prueba de Ji al cuadrado. Preponderaron los afectados con trombosis valvular (60,4 por ciento) y Razón Normalizada Internacional menor de 2,5; mientras que esta última en las hemorragias fue superior a 3,5. Aquellos con más de un factor de riesgo asociado presentaron mayor cantidad de episodios trombóticos; eventos que tuvieron menor incidencia cuando se integraron warfarina y aspirina al tratamiento


An observational, descriptive and cross-sectional study of 51 patients with valve prosthesis was carried out. They were admitted to the Cardiology Center of Saturnino Lora Torres Teaching Clinical Surgical Provincial Hospital due to valve thrombosis or bleeding episodes, from January, 2012 to December, 2014, with the purpose of estimating the variations in the International Standard Ratio values and their association with these events. The chi-square test was carried out. Those patients affected with valve thrombosis (60.4 percent) and International Standard Ratio under 2.5 were predominant; while the latter in bleedings was over 3.5. The patients with more than one associated risk factor presented higher quantity of thrombosis episodes; events that had less incidence when warfarin and aspirin were included in the treatment

ABSTRACT

O sistema MitraClip® foi recentemente aprovado para uso clínico no Brasil para o tratamento percutâneo da insuficiência valvar mitral. Esse dispositivo se baseia na cirurgia de Alfieri, criando um orifício duplo pela união central das duas cúspides da valva mitral. Descrevemos aqui os dois primeiros procedimentos realizados em nosso meio utilizando esse dispositivo. Tratam-se de duas pacientes do sexo feminino, consideradas de alto risco cirúrgico pela idade avançada e pela presença de comorbidades, portadoras de insuficiência mitral degenerativa por prolapso/flail associado à rotura de cordoalhas. Nos dois casos, obteve-se redução expressiva da intensidade da regurgitação mitral com a utilização do MitraClip®, demonstrando o grande potencial dessa tecnologia inovadora para o tratamento percutâneo da insuficiência valvar mitral.


The MitraClipTM system has been recently approved for clinical use in Brazil for percutaneous treatment of mitral valve regurgitation. This device is based on the Alfieri surgical procedure, creating a double orifice by bringing together the central segments of the two mitral valve cusps. This report describes the first two procedures performed in Brazil using this device. Two female patients considered to be at high surgical risk due to advanced age and presence of comorbidities were treated, with degenerative mitral regurgitation due to prolapse/flail, associated with chordae tendineae rupture. In both cases, significant mitral regurgitation intensity reduction was obtained using the MitraClipTM, demonstrating the great potential of this innovative technology for the percutaneous treatment of mitral valve regurgitation.

ABSTRACT

We present a case report of a infective endocarditis by Corynebacterium pseudodiphtheriticum in a young patient eight years old with bicuspid aortic valve that led to a severe neurological embolism and death. Corynebacterium pseudodiphtheriticum is part of the nasopharyngeal and skin flora. However, there are cases reported of endocarditis usually associated with immunocompromised patients that mostly presented a poor clinical outcome.


Se presenta el caso clínico de una endocarditis infecciosa por Corynebacterium pseudodiphtheriticum en un niño de 8 años, portador de una valvulopatía aórtica bicúspide, que falleció por una embolia cerebral grave. Corynebacterium pseudodiphtheriticum forma parte de la microbiota de la piel y nasofaringe. Sin embargo, se han descrito casos de endocarditis en pacientes inmunocomprometidos, asociados, en su mayoría, a una mala evolución clínica.

ABSTRACT

ABSTRACT A 27-year-old woman presented with a history of long-standing poor vision in both eyes. Ophthalmologic examination after pupillary dilatation revealed bilateral lens coloboma situated in the inferotemporal quadrant. No associated ocular abnormalities were seen, except amblyopia. A bicuspid aortic valve was observed during echocardiography during systemic evaluation. Lens coloboma usually occurs unilaterally; however, bilateral lens coloboma which is isolated or associated with other ocular malformations is also encountered. This is the first description of bilateral isolated lenticular coloboma associated with bicuspid aortic valve. Although the association between bicuspid aortic valve and lens coloboma may be an incidental finding, they may be components of an unknown syndrome.


RESUMO Uma mulher de 27 anos apresentou-se com uma história de longa data de deficiência visual em ambos os olhos. O exame oftalmológico após dilatação pupilar revelou coloboma de cristalino bilateral localizado no quadrante temporal inferior. Nenhuma outra alteração ocular associadas foi observada, exceto ambliopia. A valva aórtica bicúspide foi diagnosticada no exame de ecocardiograma durante a avaliação sistêmica. Coloboma cristaliniano ocorre geralmente de forma unilateral, no entanto já foi descrito bilateralmente, associado a outras malformações oculares ou isolado. Esta é a primeira descrição de coloboma cristaliniano isolado bilateral associado à valva aórtica bicúspide. Embora a associação de valva aórtica bicúspide e coloboma cristaliniano no nosso caso pode ter sido um achado incidental, eles podem ser componentes de uma síndrome desconhecida.

ABSTRACT

A cardiopatia reumática é um importante problema de saúde pública. Há escassez de dados sobreinfluência de variáveis cirúrgicas na mortalidade de pacientes reumáticos submetidos dupla-troca valvar (DTV).Objetivo: Identificar possíveis variáveis cirúrgicas associadas à mortalidade de pacientes reumáticos submetidos à DTV.Métodos: Estudo retrospectivo de corte transversal, incluindo 104 pacientes >18 anos, com diagnóstico prévio devalvopatia reumática, submetidos à cirurgia de DTV no período de janeiro de 2007 a dezembro de 2011. A coletade dados utilizou os prontuários de pacientes do Hospital Ana Nery, Salvador, BA, Brasil.Resultados: Observou-se diferença estatística significativa entre os grupos do desfecho (óbito intra-hospitalar/alta hospitalar) em relação às variáveis, respectivamente: tempo de anoxia (minutos) de 149,17±40,99 e 123,99±24,12(p=0,001); tempo de CEC 185,53±54,59 e 157,34±34,62 (p=0,006); e o tempo cirúrgico total 350,29±56,69 e 295,23±63,98(p=0,002). Os pacientes que realizaram outro procedimento associado à DTV, no mesmo tempo cirúrgico,apresentaram maior mortalidade (n=10; 31,2%), em relação aos que realizaram apenas a DTV (n=9; 12,8%) (p=0,027).Houve também associação significativa na comparação de pacientes com reabordagem cirúrgica com aqueles querealizaram única abordagem (p<0,001). Não houve diferença estatística quando se comparou desfecho hospitalare os tipos de próteses utilizadas (p=0,219). Conclusões: As variáveis cirúrgicas que tiveram influência na mortalidade foram: tempos de anoxia, de CEC, de cirurgia total, com possíveis pontos de corte, respectivamente, de 150 min, 100 min e 300 min. A necessidade de reabordagemno pós-operatório hospitalar e a realização de outro procedimento no mesmo ato também mostraram significância...


Rheumatic heart disease is a major public health issue. Data on the influence of surgical variables in mortality in rheumatic patients undergoing double valve replacement (DVR) are scarce. Objective: Identify potential surgical variables associated with mortality in rheumatic patients undergoing DVR. Methods: Retrospective cross-sectional study including 104 patients over 18 years, previously diagnosed with rheumatic heart-valve disease, and undergoing DVR surgery from January 2007 to December 2011. Data collection: medical records of patients from HospitalAna Nery, Salvador, Brazil.Results: Outcome groups (in-hospital death vs. hospital discharge) had a significant statistical difference in relation to variables, respectively:anoxia time (in minutes) of 149.17±40.99 and 123.99±24.12 (p=0.001); CPB time 185.53±54.59 and 157.34±34.62 (p=0.006); and totalsurgical time 350.29±56.69 and 295.23±63.98 (p=0,002). Patients who underwent another procedure associated with DVR for the same surgical time showed higher mortality rates (n=10; 31.2%) compared to those who underwent DVR only (n=9, 12.8%) (p=0.027). There was also a significant association when comparing patients with surgical rapprochement with those who underwent one surgery only(p<0.001). There was no statistical difference between hospital outcome and the types of prostheses used (p=0.219). Conclusions: The surgical variables that influenced mortality were: anoxia, CPB and total surgical times, with potential cutoff points of 150, 100 and 300 minutes, respectively. The need for rapprochement during the in-hospital postoperative period, and the performance of another associated procedure in the same surgery were also significant...

ABSTRACT

Paciente jovem, internado por endocardite em valva aórtica bivalvular, com extensão perianular da infecção (abscesso mitral com perfuração de cúspide), apresentando insuficiência aórtica e mitral importantes. Evoluiu com choque misto, baixo débito cardíaco efetivo, acidose metabólica, insuficiência respiratória e insuficiência renal aguda dialítica secundária a glomerulonefrite por deposição de imunocomplexos. Instituído tratamento para insuficiência cardíaca, antibioticoterapia de amplo espectro, suporte ventilatório não invasivo e hemodiálise, apresentando melhora do quadro clínico. Submetido à troca valvar aórtica por prótese biológica e plastia mitral, com bom resultado cirúrgico. Não havia relato de procedimento dentário prévio, outras portas de entrada para microrganismos nem uso de drogas ilícitas por via intravenosa. Bacteremias espontâneas podem ser implicadas, certamente, nesses casos. Parece não haver redução da incidência de infecções valvares com uso de profilaxia antibiótica em portadores de valvas nativas alteradas, segundo as atuais recomendações.


Young patient, hospitalized for infective endocarditis in bicuspid aortic valve with extension periannular infection (abscess with perforation of mitral leaflet) presenting significant aortic and mitral insufficiency. Evolved with mixed shock, low cardiac output effective, metabolic acidosis, respiratory failure and acute renal failure requiring dialysis secondary to glomerulonephritis by immune complex deposition. Established treatment for heart failure, broad-spectrum antibiotic therapy, noninvasive ventilatory support and hemodialysis, with clinical improvement. Underwent to aortic valve replacement and mitral valve bioprosthesis with good outcome. There was no report of previous dental procedure, other ports of entry for microorganisms and drug addiction. Spontaneous bacteremia can be certainly involved in these cases. There seems no reduction in the incidence of valvular infections with use of antibiotic prophylaxis in patients with native valves changed, according to current recommendations.

ABSTRACT

Relatamos o caso de ruptura de cordoalha mitral em um paciente adulto jovem, com apresentação clínica de febre, novo sopro cardíaco e disfunção respiratória, condição em que a hipótese de endocardite infecciosa é mandatória. Entretanto, o curso clínico, com ausência de critérios maiores para endocardite, a presença concomitante de crise tireotóxica e uma válvula mitral sem outras alterações estrututurais ecocardiográficas, reforça a hipótese alternativa de rutura de cordoalha associada ao estado hiperdinânimo. Os achados foram apropriadamente documentados e confirmados por ecocardiograma 3D. A revisão da literatura existente descreve que, embora a presença de regurgitação mitral leve a moderada seja altamente prevalente na tireotoxicose, a ruptura mitral na ausência de outras anormalidades estruturais é um achado raro e inesperado.


We report a case of a mitral chordaea rupture in a young adult patient presenting with fever, new cardiac murmur and respiratory distress, where the hypothesis of infective endocarditis was primarily selected as the main clinical concern. However, the clinical course in the absence of major criteria for endocarditis, the concomitant presence of a thyrotoxic state and no other echocardiographic detected structural alterations, strengthened the alternative hypothesis of primary rupture due to the hyperkinetic state. These findings were thoroughly documented and confirmed by 3D-echocardiography. The literature review describes that, although mild to moderate mitral regurgitation is highly prevalent in thyrotoxicosis, mitral rupture, in the absence of a previous structural abnormality, is a rare unexpected finding.

ABSTRACT

A eficácia do tratamento de tumores como linfoma Hodgkin e o câncer de mama com o uso da radioterapia reduziu, significativamente, a morbidade e mortalidade desses pacientes. Todavia, com o aumento da sobrevida, as complicações cardiovasculares, entre elas, as lesões valvares começaram a surgir, anos ou até décadas após a radioterapia. O acompanhamento com o ecodopplercardiograma, após a radioterapia, é indispensável como medida de detecção precoce e acompanhamento evolutivo, devido ao seu baixo custo e fácil acesso. O objetivo deste estudo é relatar quatro casos de pacientes que desenvolveram lesão valvar aórtica após radioterapia.


Treatment efficacy of tumors like Hodgkin’s Lymphoma and breast cancer with the use of radiotherapy has significantly reduced morbidity and mortality of these patients. However, with the increase of survival, cardiovascular complication, e.g., valvar lesions has arisen years to decades after the end of radiotherapy. The following with echocardiography after radiotherapy is an essential step in early detection and following, because of low cost and easy access. The aim of this paper is to report four cases of patients that developed aortic valvar lesion after radiotherapy.
