ABSTRACT

Fundamentos: A valvoplastia mitral por cateter-balão foi introduzida em 1984 por Inoue e colaboradores, e atualmente é considerada o método de eleição no tratamento da estenose mitral. Objetivo: Comparar resultados de valvoplastia mitral em pacientes com estenose mitral com comprometimento subvalvar ≥3 e <3. Métodos: Estudo retrospectivo com 104 pacientes submetidos à valvoplastia mitral com balão de Inoue. Os pacientes foram estratificados em dois grupos: com comprometimento subvalvar (ASV) ≥3 e ASV <3. Realizada a comparação dos resultados imediatos, aos 12 meses e aos 24 ou mais meses entre os grupos com os dados obtidos por estudo ecocardiográfico e hemodinâmico. Resultados: Os resultados imediatos mostraram sucesso nos dois grupos, com significância estatística pré/pós procedimento, quanto aos parâmetros ecocardiográficos e hemodinâmicos, e ausência de diferenças significativas entre os grupos. Os resultados ecocardiográficos aos 12 meses evidenciaram que o gradiente médio e a área valvar foram semelhantes e sem significância estatística entre os grupos, o mesmo a correndo na comparação dos resultados ecocardiográficos aos 24 ou mais meses. Conclusão: Os resultados obtidos com a valvoplastia mitral com o balão de Inoue não diferiram tanto nos pacientes com comprometimento do aparelho subvalvar ≥3 quanto <3.


Background: Balloon mitral valvuloplasty was introduced in 1984 by Inoue et al and is currently considered the method of choice in the treatment of mitral stenosis. Objective: To compare results of mitral valvuloplasty in patients with mitral stenosis with subvalvular impairment ≥3 and <3. Methods: Retrospective study with 104 patients undergoing mitral valvuloplasty with Inoue balloon. Patients were stratified into two groups: subvalvular impairment (SVI) ≥3 and SVI <3. The immediate results were compared at 12 months and 24 months or more between the groups with data obtained by echocardiography and hemodynamic study. Results: The immediate results revealed success in both groups, with statistical significance pre/post-procedure regarding the echocardiographic and hemodynamic parameters and no significant differences between groups. Echocardiographic results at 12 months showed that the mean gradient and the valve area were similar and not statistically significant between the groups, the same occurring in the comparison of echocardiographic results at 24 or more months. Conclusion: The results obtained with mitral valvuloplasty with Inoue balloon did not differ both in patients with subvalvular impairment ≥3 and <3.

ABSTRACT

Cervical aortic arch is a rare anomaly occasionally associated with other cardiovascular abnormalities. We present a case of tortuous left cervical aortic arch associated with hypoplastic transverse arch, coarctation of the aorta, and right brachiocephalic arteries arising below the coarctation and stenotic origin of the left subclavian artery. These multiple anatomic anomalies, which are associated in our case, have not been described in a single patient previously.

ABSTRACT

A embolização percutânea transcateter tornou-se o tratamento de escolha para fístulas arteriovenosas pulmonares (FAVPs), na maioria dos casos em substituição à intervenção cirúrgica. Os dispositivos clássicos, tais como coils intravasculares e balões destacáveis, provaram ser um sucesso para oclusões percutâneas de FAVPs pequenas ou médias; porém, não são ideais nas fístulas maiores e de alto fluxo pelo risco de embolização para a circulação sistêmica. Relatamos o caso de uma mulher de 49 anos de idade com FAVP de alto fluxo e manifestações neurológicas isquêmicas prévias, submetida com sucesso a fechamento percutâneo com AmplatzerTM Vascular Plug II, um dispositivo projetado para oclusão de anormalidades vasculares.


Percutaneous transcatheter embolization has become the treatment of choice for pulmonary arteriovenous fistulae (PAVFs), replacing surgical intervention in most cases. Classical devices, such as intravascular coils and detachable balloons, have proven to be successful for percutaneous occlusions of small or medium-sized PAVFs; however, they are not ideal for larger and high flow fistulae due to therisk of embolization to systemic circulation. The case of a 49-year-old woman with high flow pulmonary fistula and previous neurological ischemic manifestations undergoing successful transcatheter closure with an AmplatzerTM Vascular Plug II, a device designed for occlusion of vascular abnormalities, is reported.

ABSTRACT

Nos últimos quinze anos, o tratamento da insuficiência cardíaca (IC) adquiriu especial relevância não apenas na cardiologia, mas na medicina interna. Um grande número de novos medicamentos, baseados em uma farmacocinética e apoiados por grandes estudos multicêntricos, tem permitido melhorar a sobrevida e a qualidade de vida de inúmeros pacientes espalhados pelo globo. Quando se achou que os fármacos recém-introduzidos no cotidiano tinham controlado sinais e sintomas da IC, surgiram novas alternativas terapêuticas, com destaque para a ressincronização cardíaca. Mais recentemente, outras opções de tratamento vêm surgindo, culminando na terapia celular. Este artigo realiza uma revisão da literatura já que este tema se torna de vital importância no dia-a-dia da cardiologia clínica.

ABSTRACT

A ruptura da parede livre do ventrículo esquerdo é uma dramática, porém nem sempre fatal complicação do infarto agudo do miocárdio. No entanto, se o diagnóstico correto for retardado, o tratamento cirúrgico pode ser comprometido. Os autores relatam um caso de volumoso pseudo-aneurisma de parede inferior de ventrículo esquerdo diagnosticado ao estudo angiográfico.

ABSTRACT

OBJECTIVE: To assess stent implantation without previous dilation with a conventional balloon catheter to treat coronary artery obstructions, by using low profile guiding catheters and the transradial approach. METHODS: The transradial approach is attractive due to the possibility of avoiding the trauma caused by the balloon, its shorter time of performance, reduced exposure to radiation, and the use of lower quantities of contrast medium than those usually required in this type of procedure. RESULTS: The initial experience of direct stent implantation with low profile guiding catheters and the transradial approach was analyzed in 45 patients, whose mean age was 65 years. All procedures were successful, with no major complications in the in-hospital phase. CONCLUSION: The results obtained with the population studied proved that the transradial approach is safe, effective, and has very few risks of complications.

ABSTRACT

OBJETIVO: Avaliar o implante de stents sem dilatação prévia com cateter balão convencional para o tratamento das obstruções coronarianas, utilizando-se cateteres guias de baixo perfil através da técnica radial. MÉTODOS: A técnica radial é atraente pela possibilidade de se evitar o trauma provocado pelo balão, menor tempo para sua realização, exposição reduzida à radiação e consumo de contraste em quantidades inferiores às habitualmente usadas neste tipo de procedimento. RESULTADOS: Analisada a experiência inicial de implante direto de stents, através de cateteres de baixo perfil por via radial, em 45 pacientes, com idade média de 65 anos. Em todos os casos houve sucesso no procedimento sem complicações maiores na fase hospitalar. CONCLUSAO: Os resultados com a população estudada demonstraram ser a técnica radial segura, eficaz e com muito baixo risco de complicações.

ABSTRACT

OBJECTIVE: To report the clinical and echocardiographic findings of bioprosthetic mitral valve thrombosis and the value of transesophageal echocardiography (TEE) in its diagnosis and monitoring of thrombolysis. METHODS: One hundred and eleven patients with mitral bioprostheses underwent TEE, and 4 out of 7 suspected of having a thrombus on these prostheses were included in the study (mean age = 60.2+/-10.2 years; 2 men). The diagnosis was confirmed with serial TEE and clinical evolution. The morphologic features of the prosthetic leaflets, as well as the presence and characteristics of attached echogenic masses were investigated. The mean gradient through the prosthesis and the valvular area were obtained. RESULTS: The diagnosis of bioprosthetic mitral valve thrombosis was established 48.7+/-55.2 months after surgery. Two patients had ischemic stroke in the early postoperative period. The mean overall gradient was high (11.4+/-3 mmHg) and the valvular area reduced (1.24+/-0.3 cm2). On TEE, echogenic masses on the left ventricular face of the mitral bioprosthesis suggestive of thrombus were evidenced in all patients. On serial TEE (136+/-233 days), in 2 patients the thrombus had disappeared and in 2 others it was smaller after treatment, the mean gradient dropped to 6.2+/-3 mmHg (P = 0.004; 95% CI), and the valvular area increased to 2.07+/-0.4 (P = NS). CONCLUSION: TEE proved to be useful for detecting bioprosthetic mitral valve thrombosis and was effective in monitoring the treatment in all patients.

ABSTRACT

OBJETIVO: Descrever os achados clínicos e ecocardiográficos de trombose em prótese biológica mitral e o valor do ecocardiograma transesofágico (ETE) no diagnóstico e monitoração da lise do trombo. MÉTODOS: Foram estudados ao ETE 111 pacientes com prótese biológica mitral, e incluídos 4 de 7 com suspeita de trombo nestas próteses (idade média = 60,2±10,2 anos; 2 homens). O diagnóstico pôde ser confirmado pela realização seriada do ETE e pela evolução clínica. Investigaram-se os aspectos morfológicos dos folhetos da prótese, e presença e característica das massas ecogênicas anexas. Foram obtidos o gradiente médio pela prótese e a área valvar. RESULTADOS: O diagnóstico de trombo em prótese biológica mitral foi realizado 48,7±55,2 meses após a cirurgia. Dois pacientes apresentaram acidente vascular encefálico isquêmico no pós-operatório imediato. O gradiente médio global estava elevado (11,4±3 mmHg) e a área valvar reduzida (1,24±0,3cm²). Ao ETE, em todos foram evidenciadas massas ecogênicas em face ventricular esquerda da prótese biológica mitral, sugestivas de trombo. No ETE seriado (136±233 dias), houve desaparecimento do trombo em dois casos e redução do trombo nos outros dois, após tratamento. O gradiente médio reduziu para 6,2±3 mmHg (p=0,004; IC 95 por cento), e a área valvar aumentou para 2,07±0,4 (p=ns). CONCLUSAO: O ETE mostrou-se útil na detecção de trombo em prótese biológica mitral e eficaz na monitoração do tratamento, em todos casos.

ABSTRACT

We report a rare case of anomalous origin of the left coronary artery from the pulmonary trunk in a 45-year-old woman. The approach and technique used for selective catheterization of an anomalous left coronary artery arising from the pulmonary trunk are described. Six years after diagnosis, echocardiography showed left ventricular disfunction, and surgical treatment was indicated again. The origin of the left coronary artery from the pulmonary trunk was closed, and the postoperative period was uneventful, with recovery of left ventricular function and disappearance of ischemic features on stress myocardial perfusion imaging with 99m Tc-sestamibi, performed 4 weeks after surgery.

ABSTRACT

A estenose mitral sintomática vem sendo tratada cirurgicamente desde a décaga de 40, e nas últimas duas décadas também por tratamento percutâneo com balões. Os estudos randomizados em que essas opções terapêuticas foram comparadas demonstram qual técnica oferece melhor resultado em um grupo selecionado de pacientes, de acordo com sua apresentação clínica. Três estudos comparando a valvoplastia mitral com balão com a comissurotomia mitral fechada apresentaram melhora significativa e similar tanto do ponto de vista clínico como dos parâmetroshemodinâmicos com os dois procedimentos, à exceção da área valvar mitral, que foi significativamentemaior no grupo tratado por valvoplastia, em um desses estudos. Outra técnica cirúrgica para o tratamento da estenose mitral é a comissurotomia mitral aberta.Estudos randomizados comparando esse tratamento com a valvoplastia mitral com balão revelaram que ambos os procedimentos produzem significativa melhora tanto clínica como hemodinâmica imediata, e após três anos de seguimento. Os resultados foram semelhantes com ambas as técnicas, à exceção da área valvar mitral, que foi significativamente maior no grupo da valvoplastia, em um desses estudos.Um estudo randomizado, com tempo de seguimento de 7 anos, comparando essas 3 técnicas detratamento, demonstrou, da mesma maneira que os anteriormente comentados, que todas as opçõesproduzem significativa melhora. Além disso, reforçou, também, que, em decorrência dos resultados clínicos e hemodinâmicos, do menor custo e da dispensa do uso de circulação extracorpórea, a valvoplastia mitral com cateter-balão é a técnica de escolha para o tratamento da estenose mitral...

ABSTRACT

Few patients with corrected transposition of the great arteries survive past 50 years of age because of the association with congenital defects, development of total atrioventricular block, and right ventricular dysfunction. We report the case of a male patient with dextrocardia in situs solitus and corrected transposition of the great arteries associated with a wide atrial septal defect and severe pulmonary valvar and subvalvar stenoses. The patient also developed a large aneurysm on the pulmonary artery, total atrioventricular block diagnosed 8 years earlier, symptoms of dysfunction of the systemic ventricle in the previous 2 years, insufficiency of the left atrioventricular valve, and aortic regurgitation. Despite all these associated anomalies, the patient developed class III cardiac decompensation only at the age of 68 years, which makes this case a rarity. The patient was clinically treated, and was discharged from the hospital in good condition

ABSTRACT

This is the report of a five-month-old child presenting clinical evidence of Pompe's disease: severe hypotonicity, hyporeflexia and congestive heart failure. The ECG showed a short PR interval, the chest radiography disclosed marked cardiomegaly, and the echocardiogram revealed marked left ventricular hypertrophy - the most typical finding of this disease. A skeletal muscle biopsy led to final diagnosis, because in the histopathologic study marked increased glycogen accumulation was evident. Death occurred two months after symptom onset.

ABSTRACT

PURPOSE--To compare the doses of 750,000 and 1.5 million units (U) of streptokinase (SK), relatively to the left ventricular (LV) systolic function analyzed through contrasted ventriculography. METHODS--We included 110 patients with acute myocardial infarction (AMI) within 6h of the onset (mean-age 60 years, 83.6 men), that were randomized to receive 750,000U of SK in 15 min (55 patients), or 1.5 million U in 30 min (55 patients). The study main goal was the comparison between the groups relatively to LV ejection fraction, global and regional shortening, obtained at the fifth day of the AMI. RESULTS--The 750,000 and 1.5 million groups were homogeneous relatively to 15 analyzed variables. Relatively to the main goal of the study, it was found respectively: a) ejection fraction analysis (median): 64 and 60.5 for the total population (p = 0.25, 95 CI -2.7 to 10), 64 and 57.5 for anterior AMI (p = 0.2, 95 CI -3.6 to 16.3), 65 and 65 for inferior AMI (p = 0.99, 95 CI -8.4 to 8.4); b) global shortening analysis: -2.53 and -2.66 for the total population (p = 0.3, 95 CI -0.47 to 0.87), -2.27 and -2.53 for anterior AMI (p = 0.18, 95 CI -0.3 to 1.4), -1.82 and 1.72 for inferior AMI (p = 0.9, 95 CI -0.82 to 0.75); c) regional shortening analysis: anterior AMI -2.6 and -2.67 (p = 0.47, 95 CI -0.7 to 1.5), inferior AMI -2.3 and -2.32 (p = 0.9, 95 CI -0.82 to 0.75). CONCLUSION--The dose of 750,000U was as efficacious as the 1.5 million relatively to LV systolic function, one of the best survival predictors of short-medium and long-term survival post AMI.


Objetivo −Comparar as doses de 750.000 e 1,5 milhão de unidades (U) de estreptoquinase (EQ), em relação à função sistólica do ventrículo esquerdo (VE), analisada através da ventriculografia contrastada. Métodos − Incluíram-se 110 pacientes com infarto agudo do miocárdio (IAM) <6h de evolução (idade mediana 60 anos, 83,6% homens) que receberam, aleatoriamente, 750.000U de EQ em 15min (55 pacientes), ou 1,5 milhão em 30min (55 pacientes). A meta principal do estudo foi a comparação entre os grupos em relação à fração de ejeção (FE), encurtamento global e regional do VE, obtidas no 5º dia do IAM. Resultados − Os grupos 750.000 e 1,5 milhão mostraram-se homogêneos em relação a 15 variáveis analisadas. Em relação à meta principal do estudo, encontraram-se, respectivamente para os grupos: a) análise da FE (mediana): 64% e 60,5% para o total da população (p=0,25, 95% IC -2,7 a 10), 64% e 57,5% para os IAM anteriores (p=0,2, 95% IC -3,6 a 16,3), 65% e 65% para os IAM inferiores (p=0,99, 95% IC -8,4 a 8,4); b) análise do encurtamento global: -2,53 e -2,66 para o total (p=0,3, 95% IC -0,47 a 0,87), -2,27 e -2,53 para os IAM anteriores (p=0,18, 95% IC -0,3 a 1,4), -1,82 e -1,72 para os IAM inferiores (p=0,9, 95% IC -0,82 a 0,75); c) análise do encurtamento regional: IAM anterior -2,6 e -2,67 (p=0,47, 95% IC -0,7 a 1,5), IAM inferior -2,3 e -2,32 (p=0,9, 95% IC -0,82 a 0,75). Conclusão − A dose de 750.000U mostrou-se tão eficaz quanto a de 1,5 milhão no que se refere à função sistólica do VE, um dos melhores preditores de sobrevida a curto, médio e longo prazos pós IAM
