ABSTRACT

This report describes the cardiac involvement of patients with mucopolysaccharidoses Type II (Hunter disease). Mucopolysaccharidoses Type II are an uncommon group of about 50 rare inherited metabolic disorders, that result from defects in lysosomal dysfunction, usually as a consequence of deficiency of a single enzyme required for the metabolism of lipids, glycoproteins or so called mucoplysaccharides. Most of this diorders are autosomal recesively inherited such as Hunter syndrome Mucopolysacharidosis. Tuype II is a lisosomal storage disease caused by a deficiency of the lysosomal ensyme iduronate 2 sulfatase. its frequency is 1 to 100.000 to 150.000 male births; is farmore common in boys. Clinical, electrocardiographical and sonographical variables were determined. As a result 18 patients were evaluated; all the patients presented cardiac involvement. Color Doppler sonocardiogram was pathological in the 100% of the patients, and 4 of them, showed mitral/and or aortic, and 4 patients with miocardic hypoertrophy, and 1 patient, pulmonary hipertension. A clinical review is prsented, and a guide for management is detailed (AU)

ABSTRACT

RESUMO Este artigo relata o caso de um homem caucasiano de 43 anos de idade com nefropatia terminal em tratamento com hemodiálise e apresentando endocardite infecciosa das válvulas aórtica e tricúspide. O quadro clínico foi dominado pelo comprometimento neurológico, devido à embolia cerebral e a componentes hemorrágicos. Uma tomografia computadorizada tóraco-abdominal revelou um êmbolo séptico pulmonar. O paciente foi submetido à antibioticoterapia empírica utilizando ceftriaxona, gentamicina e vancomicina, sendo o tratamento modificado para flucloxacilina e gentamicina após o isolamento de S. aureus nas hemoculturas. A equipe multidisciplinar determinou que o paciente deveria ser submetido à substituição de válvulas após estabilização da hemorragia intracraniana; contudo, no oitavo dia após a hospitalização, o paciente entrou em parada cardíaca causada por embolia séptica pulmonar maciça, vindo a falecer. Apesar do risco de agravamento da lesão hemorrágica cerebral, em pacientes de alto risco deveria ser considerado realizar precocemente uma intervenção cirúrgica.


ABSTRACT This is a case report of a 43-year-old Caucasian male with end-stage renal disease being treated with hemodialysis and infective endocarditis in the aortic and tricuspid valves. The clinical presentation was dominated by neurologic impairment with cerebral embolism and hemorrhagic components. A thoracoabdominal computerized tomography scan revealed septic pulmonary embolus. The patient underwent empirical antibiotherapy with ceftriaxone, gentamicin and vancomycin, and the therapy was changed to flucloxacilin and gentamicin after the isolation of S. aureus in blood cultures. The multidisciplinary team determined that the patient should undergo valve replacement after the stabilization of the intracranial hemorrhage; however, on the 8th day of hospitalization, the patient entered cardiac arrest due to a massive septic pulmonary embolism and died. Despite the risk of aggravation of the hemorrhagic cerebral lesion, early surgical intervention should be considered in high-risk patients.

ABSTRACT

Valva pulmonar tetravalvular é uma patologia de baixa incidência que tende a ser clinicamente silenciosa, evoluindo muito raramente para disfunção valvar significativa. Pela posição da valva pulmonar no tórax, o diagnostico ecocardiografico pode ser difícil,principalmente porque, muitas vezes, não conseguimos visibilizar bem suas válvulas no corte paraesternal eixo curto. A sintomatologia pobre somada à dificuldade diagnóstica pode contribuir para os poucos relatos em pacientes vivos.

ABSTRACT

Tumor amorfo calcificado do coração consiste em uma massa cardíaca de natureza não-neoplásica, rara, que pode simular malignidade e causar sintomas por causar obstrução ou embolização de fragmentos calcificados. Apresentamos um caso de tumor em jovem de 17 anos, sexo masculino, em valva tricúspide, com achados patológicos clássicos. Preferiu-se abordar por esternotomia mediana clássica, instalação do circuito de circulação extracorpórea e atriotomia direita, exérese do tumor, plastia de DeVega na valva tricúspide e bicuspidização da mesma. O estudo anatomopatológico demonstrou presença de extensa calcificação e áreas de metaplasia óssea. O paciente evoluiu bem no pós-operatório, recebendo alta hospitalar no 8º dia pós-operatório.


Calcified amorphous tumor of the heart consists of a cardiac mass of rare nonneoplastic nature that mimics malignancy and causes symptoms due to obstruction or embolization of calcific fragments. We present a case of tumor 17-year-old young, male, in tricuspid valve, with classic pathological findings. It was preferred to approach for classic median esternotomy, installation of the circuit of extracorporal circulation and right atriotomy, exereses of tumor, DeVega's plasty in tricuspid valve and bicuspidization. The amatomopathological study demonstrated presence of extensive calcification and metaplastic bone areas. The patient had an uneventful hospitalization.

ABSTRACT

FUNDAMENTO: As cardiopatias são doenças de alta prevalência, sendo a cardite reumática uma doença de grande relevância em países em desenvolvimento. As alterações em câmaras cardíacas esquerdas se associam à disfunção endotelial, com aumento dos níveis de endotelina-1 (ET-1) e consequências sobre a circulação pulmonar, muitas vezes determinando a hipertensão pulmonar (HP). No entanto, a presença de ET-1 e seus receptores na própria valva mitral, promovendo alterações vasculares pulmonares e aumentando a deformação valvar reumática, ainda é um assunto não abordado na literatura. OBJETIVO: Determinar, mediante técnicas moleculares, a expressão dos genes da endotelina e dos seus receptores em valvas mitrais reumáticas. MÉTODOS: 27 pacientes submetidos à troca valvar mitral tiveram seu tecido valvar analisado, a fim de determinar a presença de genes de ET-1 e seus receptores A e B. Foram feitas análises histológica e molecular das valvas (divididas em fragmentos M1, M2 e M3) e colhidos dados clínicos e epidemiológicos dos pacientes. Foram divididos em três grupos: valvopatia mitral, mitroaórtica e pacientes reoperados. RESULTADOS: O estudo mostrou a manifestação do gene da ET-1 em 40,7 por cento dos espécimes e de seu receptor A em todas as amostras, com manifestação minoritária do gene do receptor B (22,2 por cento). CONCLUSÃO: Todos os pacientes expressaram a presença do gene do receptor A. Não houve diferença estatística quanto à gravidade da doença, expressa em classe funcional, e aos subgrupos estudados (valvopatas mitrais, mitroaórticos e pacientes reoperados), ou quanto à expressão dos genes da ET-1 e seus receptores entre os subgrupos estudados (valvopatas mitrais, mitroaórticos e pacientes reoperados).


BACKGROUND: Cardiopathies are high prevalence conditions. Among them, rheumatic carditis is of high relevance in developing countries. Left cardiac chamber changes are associated to endothelial dysfunction and ET-1 levels increase. Pulmonary circulation is then affected, and not seldom leading to pulmonary hypertension (PH). However, the presence of ET-1 and its receptors in the mitral valve itself - promoting pulmonary vascular changes, with increased rheumatic valvular deformation - has not been discussed in the literature. OBJECTIVE: To determine the expression of endothelin gene and its receptors in rheumatic mitral valves through techniques of molecular genetics. METHODS: Twenty-seven patients submitted to mitral valve replacement had their valvular tissue examined to determine the presence of ET-1 genes and their A and B receptors. Histological and molecular analysis of the valves was performed (divided into M1, M2 and M3 fragments), with patients' clinical and epidemiological data collected. Patients were divided into 3 groups (mitral valvopathy, mitroaortic valvopathy, and reoperation patients). RESULTS: The study showed endothelin-1 gene expression in 40.7 percent specimens and A receptor in all samples; receptor gene B had lower expression (22.2 percent). CONCLUSION: All patients showed A receptor gene expression. No statistically significant difference was observed in regard to condition severity, expressed according to functional class, and subgroups (mitral valvopathy, mitroaortic valvopathy, and reoperation patients).

ABSTRACT

La insuficiencia valvular tricuspídea funcional es la causa principal de disfunción de esta válvula, la cual es generada por daño estructural del ventrículo izquierdo, de la válvula mitral o por hipertensión pulmonar. La presencia de insuficiencia tricuspídea (IT) funcional se ha asociado a mayor morbi-mortalidad de los pacientes. Estos, presentan una relación de riesgo de 2,2 de mayor muerte que los pacientes con grado leve, por lo tanto, es un problema a tomar en cuenta una vez que aparece. La pérdida de la estructura tricuspídea tridimensional en silla de montar, por una estructura más plana, además de la dilatación del anillo tricuspídea son los mecanismos que generan IT funcional. Las técnicas quirúrgicas actuales de plastia tricuspídea sólo reparan la dilatación del anillo. Existe clara evidencia a favor de corrección de IT severa, en el momento de corrección de válvulas izquierdas; y de corrección de IT moderada, cuando se encuentra asociada a dilatación anual o en presencia de hipertensión pulmonar. Sin embargo, conductas más agresivas han sido publicadas con buenos resultados, donde se impone la realización de reparación tricuspídea "profiláctica". Las técnicas quirúrgicas actuales dirigidas a redimensionar el anillo a través de sutura o con la colocación de anillos presentan el problema de alta tasa de IT residual además de una alta tasa de recurrencia. Por otra parte, la colocación de prótesis tricuspídea acarrean los problemas de anticoagulación y trombosis protésica.


Functional tricuspid valve insufficiency is the main cause for this valve dysfunction, which is due to structural damage in the left ventricle, the mitral valve, or to pulmonary hypertension. The presence of functional tricuspid insufficiency (TI) has been associated with a higher morbidity and mortality rate of patients. These patients show a higher relative risk for death of 2,2 compared to patients with mild TI. Therefore, this is a health problem to tackle from its very onset. Mechanisms such as the loss of a saddle-shaped 3D tricuspid structure for a more planar structure, and the tricuspid annular dilatation, generate functional TI. Current surgical techniques of tricuspid valve plasty only repair annular dilatation. Clear evidence exists in favor of severe TI correction at the time left valves are corrected, as well as in favor of moderate TI correction when associated with annular dilatation or in the presence of pulmonary hypertension. However, more aggressive behaviors have been published with good results wherein performing a "prophylactic" tricuspid valve repair is a must. Current surgical techniques aimed at resizing the annulus with either ring or suture annuloplasty have a high residual TI rate problem, in addition to a high recurrence rate. On the other hand, implanting a tricuspid prosthesis may have anticoagulation and prosthetic valve thrombosis problems.

ABSTRACT

Se presentan los resultados de la revisión sistemática de 414 historias médicas de la Clínica de Enfermedad Valvular Cardíaca del Centro Cardiovascular Regional-Ascardio, en el período octubre 2002-julio 2008. Los casos fueron evaluados por el grupo de trabajo que integra la unidad. La enfermedad valvular cardíaca fue dividida según su presentación topográfica como lesión única o predominante, según su grado de severidad y repercusión hemodinámica. La válvula más frecuentemente comprometida fue la mitral (87,4%), seguida por la tricúspide (76,3%), aórtica (72,9%) y pulmonar (8,6%). 72,5% presenta al menos una lesión (insuficiencia o estenosis) severa. La etiología más frecuente fue la degenerativa (40,6 %). Según etiología, el promedio de edad es 41 años para la congénita, 47 años para la reumática y 64 años para la degenerativa. Se observa una importante limitación en el registro de factores de riesgo coronario, a pesar de ser un centro especializado. Se divide el análisis en patología valvular mitral única o predominante, aórtica predominante, doble lesión aórtica y mitral severas, patología valvular tricuspídea y pulmonar. Finalmente se presenta una discusión sobre la interpretación de los resultados.

ABSTRACT

Primary intra-cardiac tumors are rare. Most of them are benign. Of the benign tumors, myxomas are the most common. Others are lipoma, rhabdomyoma, hemangioma, and papillary fibroelastoma (PFE). PFE is a relatively rare benign tumor of the heart. It occurs commonly on cardiac valves and is often an incidental finding. They are most commonly discovered during autopsy, but may present with thromboembolism, which is a dreaded complication. It is important to be aware of this entity because even though it is benign it may present with life-threatening complications, which are well documented in literature. Surgery is the treatment of choice for these tumors. We present the case of a 30-year-old male in whom PFE was an incidental finding.

ABSTRACT

We determined the pattern and severity of valvular involvement in 100 Sudanese patients with rheumatic heart disease [RHD] in 2 centres in Khartoum in 2003. All the patients underwent history taking, physical examination and Doppler echocardiography. The commonest lesions were mitral regurgitation [84%] and aortic regurgitation [40%]. Mitral stenosis alone was uncommon [9%] which could be due to a low detection rate related to the slow stenotic process and the subtle early signs. This, together with the inconsistent history of rheumatic fever, may lead to an underestimate of the prevalence of RHD. There was a strong correlation between severity of the lesion and irregular prophylaxis [P < 0.001]

ABSTRACT

Introdução: a troca valvar aórtica é procedimento cirúrgico consagrado na estenose aórtica grave sintomática e apresenta morbi-mortalidade cirúrgica baixa apesar do aumento de pacientes de alto risco. Um objetivo que a troca valvar aórtica deveria assegurar é a de obtenção de uma área de orifício efetiva adequada para evitar estenose residual. A persistência de gradientes transvalvares residuais quando próteses aórticas péquenas são implantadas, particularmente, em pacientes com grande superfície corporal tem gerado questionamentos quanto os efeitos hemodinâmicos, tolerância e impacto na sobrevida após troca valvar aórtica...

ABSTRACT

OBJETIVO: Comparar os exames clínico e ecocardiográfico Doppler na avaliação das lesões valvares em crianças e adolescentes com febre reumática, bem como investigar a evolução da doença segundo essas avaliações. MÉTODOS: Trata-se de estudo observacional longitudinal que englobou 258 crianças e adolescentes com diagnóstico de febre reumática, baseado nos critérios de Jones. Os pacientes foram acompanhados durante o período de 2 a 15 anos. A presença e a quantificação das lesões valvares nas fases aguda e crônica foram determinadas pelas avaliações clínica e ecocardiográfica Doppler. Utilizou-se a estatística de Kappa para estimar a concordância entre as avaliações, e as evoluções clínica e ecocardiográfica Doppler da cardite e valvite, respectivamente, foram comparadas pelo teste do qui-quadrado ou de Fisher, p < 0,05. RESULTADOS: Dos 109 pacientes submetidos à avaliação ecocardiográfica Doppler na fase aguda, 31 não apresentavam clínica de cardite, mas 17 (54,8 por cento) deles mostravam lesão valvar ao ecocardiograma Doppler (valvite subclínica). Na fase crônica, 153 dos 258 tinham exame cardiovascular normal, mas 85 (55,5 por cento) desses mostravam lesão valvar ao ecocardiograma Doppler (valvopatia crônica subclínica). A involução das lesões valvares segundo a avaliação ecocardiográfica Doppler foi menos freqüente, ocorrendo em 10 (25,0 por cento) dos pacientes com valvite leve e em apenas 1 (2,5 por cento) daqueles com valvite moderada, e em nenhum com valvite grave. CONCLUSAO: A identificação de lesões valvares na febre reumática é maior se a avaliação clínica for acrescida do exame ecocardiográfico Doppler, que também mostra menor índice de regressão das lesões valvares. O diagnóstico de valvite e valvopatia subclínicas tem implicação quanto às profilaxias secundária da febre reumática e da endocardite.

ABSTRACT

In this study we attemped to determine prospectively guidelines for the optimal management of patient with valvular heart disease. At present, most of valvular heart diseases are susceptible for surgical management. it is suitable to perform the surgical management in the best moment to achieve better results. The question is: when this best moment has been lost? The present study was undertaken to qualify the best operative timing for the surgical management of the valvular heart disease, and to analyza when it should be considered late for the indication of the operative procedure

ABSTRACT

Los niveles de lípidos elevados en sangre representan un importante factor de riesgo modificable en la aparición de enfermedad coronaria en pacientes con hipertensión arterial (3). Contar con fármacos que además de ejercer su acción antihipertensiva puedan también mejorar los niveles de los lípidos en sangre, deberían ser el norte de las nuevas investigaciones en esta área. En este estudio evaluamos la modificación del perfil lipídico en pacientes con hipertensión arterial en estadio I y II, tratados con valsartán, un antagonista de los receptores AT1 de la Angiotensina II. Se realizó un estudio prospectivo en 28 pacientes de ambos sexos, con edad promedio de 40,2 años y diagnóstico inicial de Hipertensión Arterial. Se incluyeron únicamente pacientes con Hipertensión Arterial en Estadio I y II. Se realizó perfil lipídico, al inicio y tres meses después de tratamiento con 80 mg/día de valsartán. El perfil lipídico inicial indicó que más del 50 por ciento de los pacientes tenían asociada una hiperlipidemia. Tres meses después del tratamiento se observó una reducción estadísticamente significativa de Colesterol Total (p=0,0037) y de LDL (p=0,0030) al igual que las relaciones Colesterol total/HDL y LDL/HDL (p=0,000298 y p=0,000894 respectivamente). Puede recomendarse el uso de valsartán como droga hipotensora en pacientes con diagnóstico inicial de Hipertensión Arterial Sistémica, sobre todo de aquellos que presenten asociados, niveles elevados de lípidos en sangre, especialmente el colesterol total, la LDL y las relaciones colesterol total/HDL y LDL/HDL, con lo que se reduciría el riesgo de enfermedad cardiovascular

ABSTRACT

OBJECTIVES: To study the dominance of coronary artery distribution in patients with aortic valve disease. MATERIAL AND METHODS: The prevalence of left dominant coronary artery system in patients with aortic valve disease was compared with patients without aortic valve disease undergoing coronary angiography. Group 1 consisted of 237 patients with symptomatic aortic valve disease and Group 2 consisted of 241 consecutive patients without aortic valve disease undergoing cardiac catheterisation. RESULTS: Forty two patients in Group 1 and 20 patients in Group 2 (p < 0.01) showed a left dominant pattern of supply. Fifteen patients in Group 1 and eight patients in Group 2 showed a co-dominant pattern of supply (p = NS). Among patients in Group 1, there was no significant difference in the increased prevalence of left dominant system between patients with congenital or acquired aortic valve disease or between the different categories of aortic valve lesions. CONCLUSION: Patients with aortic valve disease show a statistically significant higher prevalence of left dominant pattern of blood supply. This higher prevalence of left dominance is seen in all categories of aortic valve lesions, namely, predominant aortic stenosis, predominant aortic regurgitation and in combined aortic stenotic and regurgitant lesions.

ABSTRACT

El objetivo de este estudio fue correlacionar los hallazgos obtenidos por ecocardiografía transesofágica con los obtenidos durante la cirugía y el estudio de anatomía patológica en pacientes con endocarditis infecciosa (EI) en válvula mitral y/o aórtica. Se estudiaron 28 pacientes a quienes se les realizó historia clínica, estudio bacteriológico y ecocardiograma transesofágico (ETE). En el estudio bacteriológico se encontraron hemocultivos positivos en 15 casos, en 13 los hemocultivos fueron negativos. El ETE demostró vegetaciones infecciosas en válvula mitral en 11 casos y en 5 enfermos en ambas válvulas. Complicaciones relacionadas con el proceso infecciosos se encontraron en el 53 por ciento de los casos. La incidencia de eventos embólicos fue del 25 por ciento. La concordancia entre el ETE y la anatomía patológica, en relación a la presencia de vegetaciones, fue del 92.8 por ciento y entre el ETE y la cirugía, en relación a la presencia de vegetaciones y complicaciones, fue del 89.2 por ciento. El ETE es un método de gran utilidad no sólo para el diagnóstico, sino también para el pronóstico de la EI, por su alta concordancia con los estudios de anatomía patológica y cirugía

ABSTRACT

El fibroelastoma papilar en un tumor cardiaco benigno raro, que previo al advenimiento de la ecocardiografía, era diagnosticado sólo en necropsias o de manera incidental en cirugía. Se puede presentar en la fuperficie endocárdica o en cualquiera de las válvulas, y aunque su tañamo generalmente es pequeño, se le asocia a fenómenos embolígenos, dolor torácico y muerte súbita. En este reporte se presenta el primer caso de fibroelastoma papilar, en presencia de una prótesis valvular mecánica en posición mitral, en una paciente de 55 años con cardiopatía reumática inactiva. El tumor fue detectado mediante ecocardiografía transtorácica y transesofágica
