ABSTRACT

A cirurgia minimamente invasiva é segura e eficaz no tratamento de diversas afecções cardíacas, com evolução intra-hospitalar bastante positiva. Descrevemos aqui o caso de paciente do sexo masculino, com 72 anos de idade, portador de comunicação interatrial com shunt bidirecional e bloqueio atrioventricular avançado com síncope. Foi contraindicado o fechamento da comunicação interatrial e indicado marcapasso dupla-câmara com cabos-eletrodos epicárdicos em decorrência da presença do shunt. O procedimento foi realizado por meio de minitoracotomia direita, com implante de cabos-eletrodos atrial e ventricular direitos bipolares, com gerador implantado em loja subcutânea na região infraclavicular direita. O paciente apresentou boa evolução, recebendo alta no quarto dia de pós-operatório em boas condições


Minimally invasive cardiac surgery is safe and effective in the treatment of a wide range of cardiac diseases, with very positive in-hospital outcomes. We describe the case of a 72-year-old male patient, with atrial septal defect, bidirectional shunt and advanced atrioventricular block with syncope. The atrial septal defect closure was contraindicated and he was referred for a dual-chamber pacemaker and epicardial leads implantation due to the presence of shunt. The patient underwent a right minithoracotomy with the implantation of bipolar atrial and ventricular leads and placement of a pacemaker generator in a subcutaneous envelope in the right infraclavicular region. The patient evolved well and was discharged on the fourth postoperative day in good conditions

ABSTRACT

A comunicação interatrial tipo ostium secundum (CIA OS) é uma cardiopatia congênita relativamente frequente, que causa repercussão hemodinâmica para o ventrículo direito, com sobrecarga volumétrica e dilatação da câmara. A maioria dos pacientes é assintomática, porém sintomas podem aparecer depois da segunda década de vida. O tratamento eletivo é usualmente realizado próximo ao quinto ano de vida, podendo ser indicado mais precocemente quando houver sintomatologia exuberante. O fechamento transcateter usando uma prótese de duplo disco é bem estabelecido como a primeira escolha de tratamento para a maioria dos pacientes de anatomia favorável. Foi comprovado que o forame oval patente (FOP) está associado à acidente vascular cerebral isquêmico (AVCI) em pacientes com poucos ou nenhum fator de risco de doença cardiovascular. Recentemente, foi demonstrado que a oclusão transcateter do FOP é superior ao tratamento clínico para prevenir recorrências de AVCI nessa população, em um estudo randomizado com acompanhamento clínico de longo prazo. Este manuscrito revisa as atuais indicações, critérios de seleção do paciente e o seguimento clínico dos pacientes com CIA OS e FOP submetidos ao tratamento transcateter


Ostium secundum atrial septal defect (OS-ASD) is a relatively frequent congenital heart defect that causes hemodynamic burden on the right ventricle with volume overload and chamber dilatation. Most patients are asymptomatic, however symptoms can appear after the second decade of life. Elective treatment is usually performed around the fifth year of life, and may be occasionally indicated earlier if there are exuberant symptoms. Transcatheter closure using a double disc device is well established as the first choice of treatment for most patients with suitable anatomy. Patent foramen ovale (PFO) has been shown to be associated with ischemic stroke in patients with no or limited risk factors for cardiovascular disease. It was recently demonstrated in a randomized trial with long-term follow-up that transcatheter closure of PFO is superior to medical treatment for preventing recurrences of stroke in this patient population. This manuscript reviews the current indications, patient selection criteria, and long-term follow-up in patients with OS-ASD and PFO submitted to transcatheter closure

ABSTRACT

O ecocardiograma transesofágico (ECO-TE) é o método mais utilizado para guiar otratamento percutâneo da comunicação interatrial (CIA) e do forame oval (FOP), mas a necessidade de um outro profissional para realizá-lo e de anestesia geral constituem inconvenientes para seu emprego. Oecocardiograma intracardíaco (ECO-IC) apresenta-se como alternativa ao ECO-TE, pois pode ser realizado pelo próprio operador e demanda apenas anestesia local, com leve ou nenhuma sedação. Nosso objetivo foi relatar a experiência do serviço com a oclusão de CIA/FOP guiada por ECO-IC. Métodos: O ECO-IC utiliza cateter de ultrassom, que é introduzido por via venosa em câmaras cardíacas direitas e, por meio de posicionamento variável do transdutor, obtém as imagens adequadas para a intervenção. Foram avaliadas as taxas de sucesso do procedimento e as complicações. Resultados: De 2011 a 2015, foram realizados 201 procedimentos guiados pelo ECO-IC, sendo 139 empacientes com CIA e 62 com FOP. A maioria dos pacientes era do sexo feminino (64,2%), as idades variaramde 7 a 78 anos (36,6 ± 19,3 anos) e o peso variou de 28 a 92 kg (62,5 ± 13,0 kg). Foram utilizadas próteses Occlutech Figulla®, e todas as intervenções tiveram sucesso, com tempos de fluoroscopia de 5,7 ± 2,4 minutos e tempo de procedimento de 21,5 ± 6,4 minutos. Dois pacientes (2,0%) apresentaram taquicardia supraventricular transitória e outros dois pacientes evoluíram com fístula arteriovenosa na via de acesso, com resolução espontânea no primeiro mês. Conclusões: O ECO-IC forneceu informações anatômicas precisas para guiar o fechamento da CIA/FOP com sucesso e eliminou as principais desvantagens do ECO-TE...


Transesophageal echocardiography (TEE) is the most widely used method to guide the percutaneous treatment of atrial septal defect (ASD) and patent foramen ovale (PFO), but the necessity of another professional to perform it and the need for general anesthesia are potential disadvantages. Intracardiac echocardiography (ICE) is seen as an alternative to TEE, as it can be performed by the interventionist and requires only local anesthesia with mild or no sedation. The aim of this study was to report our experience with ASD/PFO occlusion guided by ICE. Methods: The ICE uses an ultrasound catheter, which is intravenously inserted in the right heart chambers and acquires images for the intervention through variable positioning of the transducer. Success and complication rates of the procedure were evaluated. Results: From 2011 to 2015, 201 procedures guided by ICE were performed, comprising 139 in patients with ASD and 62 in those with PFO. Most patients were female (64.2%), ages ranged from 7 to 78 years (36.6 ±19.3 years), and weight ranged from 28 to 92 kg (62.5 ± 13.0 kg). Occlutech Figulla® prostheses were used and all interventions were successful, with fluoroscopy time of 5.7 ± 2.4 minutes and procedure time of 21.5 ± 6.4 minutes. Two patients (2.0%) had transient supraventricular tachycardia and two others had arteriovenous fistula at the access site, with spontaneous resolution in the first month of follow-up. Conclusions: ICE provided accurate anatomical information to guide the closure of the ASD/PFO and successfully eliminated the main drawbacks of TEE...

ABSTRACT

Defeitos congênitos múltiplos são tradicionalmente corrigidos cirurgicamente, mas, atualmente, podem ser tratados percutaneamente. Existem poucos relatos na literatura atestandosua eficácia e segurança. Objetivamos descrever uma experiência com a realização de procedimentoscombinados para tratar diferentes defeitos, congênitos e estruturais, numa mesma sessão terapêutica. Métodos: Desde 2007, foram tratados, numa mesma sessão terapêutica, diferentes defeitos. Todos foram selecionados por ecocardiograma. Os procedimentos foram realizados segundo as técnicas tradicionais já descritas para cada defeito encontrado. Resultados: Foram tratados dez pacientes, cinco do sexo masculino, com idades de 1 a 67 anos, e pesos de 11 a 90 kg. O defeito mais prevalente de forma isolada foi a persistência do canal arterial (PCA, n = 5), seguido da comunicação interatrial ostium secundum (CIA OS, n = 4) e da comunicação interventricular (CIV, n = 4). As combinações mais frequentes foram CIV com PCA (n = 2) e CIV com CIA OS (n = 2). Foram dilatadas duasestenoses valvares pulmonares com CIA OS e com forame oval patente (FOP), e uma coarctação de aorta com PCA. Adicionalmente, foi ocluído um apêndice atrial esquerdo com FOP e foi embolizada uma fístula aortopulmonar com PCA. Todos os procedimentos foram bem-sucedidos. O tempo médio de seguimento foi de 31 ± 28,1 meses, havendo apenas duas complicações. Não houve nenhum óbito. Conclusões: A pequena série de casos relatada mostrou que os procedimentos combinados foram seguros e eficazes, podendo ser reproduzidos por operadores experientes em centros especializados, podendo vir a se constituir como primeira opção terapêutica para esses pacientes...


Multiple congenital defects are traditionally corrected surgically, but nowadays can be treatedpercutaneously. There are few reports in the literature attesting to its efficacy and safety. We aimed to describe an experience with combined procedures to treat different congenital and structural defects, in a single therapeutic session.Methods: Since 2007, different defects were treated in a single treatment session. All were selected byechocardiography. The procedures were performed using traditional techniques already described for each defect.Results: Ten patients were treated, five males, aged 1-67 years, weighting 11-90 kilograms. The most prevalent isolated defect was patent ductus arteriosus (PDA, n = 5), followed by ostium secundum atrial septal defects (ASD, n = 4) and ventricular septal defects (VSD, n = 4). The most common combinations were VSD with PDA (n = 2) and VSD with osASD (n = 2). Two pulmonary valve stenosis were dilated with ASD and patent foramen ovale (PFO), and one aorta coarctation with PDA. Additionally, a left atrial appendage with PFO was occluded and an aorto pulmonary fistula with PDA was embolized. All procedures were successful. The mean follow-up was 31 ± 28.1 months, with only two complications. There were no deaths.Conclusions: The small number of reported cases showed that the combined procedures were safe andeffective and can be reproduced by experienced operators in specialized centers and may be considered asthe first therapeutic option in these patients...

ABSTRACT

Introdução: A oclusão percutânea das comunicações interatriais tipo ostium secundum com as próteses disponíveis comercialmente é procedimento seguro e eficaz. Apresentamos a experiência com duas próteses de nova geração, com fios de nitinol revestidos. Métodos: Descrevemos as características das próteses, a técnica de implante e os resultados de pacientes portadores de comunicações interatriais, tratados com as próteses Lifetech CERA® ASD Occluder e Cocoon Septal Occluder. Resultados: Foram realizados procedimentos em 49 pacientes, sendo 37 do sexo feminino. A idade variou de 7 a 68 anos, e o peso de 17 a 90 kg. A borda aórtica estava presente em 34,7% e aneurisma de septo atrial em 14,3% dos pacientes. Os diâmetros estáticos dos orifícios principais foram de 13 ± 7 mm e os diâmetros estirados de 22 ± 7 mm. O implante foi possível em todos os casos, sendo empregados 55 dispositivos. Foram utilizadas próteses CERA® em 45 pacientes e Cocoon nos demais. Três pacientes necessitaram ocluir um segundo orifício. Durante os procedimentos, foi necessária a substituição da primeira prótese por outra de maior diâmetro em dois casos e por deformidade da prótese (configuração em tulipa) no terceiro caso. A oclusão imediata ocorreu em 91,9% e em 95,9% no 6° mês. Não ocorreram óbitos ou outras complicações significativas. Conclusões: O manuseio das próteses CERA® e Cocoon foi simples e reprodutível nas mãos de operadores experientes. As taxas de oclusão imediata foram semelhantes às obtidas com as próteses Amplatzer®. Mais estudos e seguimento de longo prazo se fazem necessários para determinar as reais vantagens do revestimento dos fios de nitinol.


Background: Transcatheter occlusion of secundum atrial septal defects using commercial available devices is a safe and effective procedure. We present our experience with two new generation coated nitinol wire devices. Methods: We report device characteristics, implantation technique and outcomes of patients with atrial septal defects treated with the Lifetech CERATM ASD Occluder and the Cocoon Septal Occluder. Results: Procedures were performed in 49 patients, 37 were female. Ages ranged from 7 to 68 years and body weight from 17 to 90 kg. The aortic rim was present in 34.7% and atrial septal aneurysms in 14.3% of the patients. Mean diameter was 13 ± 7 mm whereas the balloonstretched diameter was 22 ± 7 mm. Implantation was possible in all cases and 55 devices were used. Fortyfive CERATM and four Cocoon devices were used. Three patients required occlusion of a second orifice. During the procedures the first device had to be replaced by a larger one in two cases, and in the third case it was replaced due to a tuliplike malformation of the left atrial disc. Immediate occlusion occurred in 91.9% and in 95.9% at 6 months. There were no deaths or other significant complications. Conclusions: The use of both CERATM and Cocoon devices was simple and reproducible in experienced hands. Shortterm occlusion rates were similar to the ones obtained with the AmplatzerTM device. More studies and longterm followup are required to determine the actual advantages of coated nitinol wire devices.

ABSTRACT

Percutaneous device closure for secundum atrial septal defects (ASDs) has been performed commonly and safely with high success rates. However, it is still challenging to close ASDs that are surrounded with deficient or hypermobile rims and could be compromised with an unexpected migration of device. We report a case of percutaneous Amplazter Septal Occluder (ASO; St. Jude Medical Inc., St. Paul, Minnesota, USA) device closure for an ASD with a thin and floppy interatrial septum, which immediately migrated into the right atrium and was not pulled back into the delivery sheath. To our knowledge, this is the first report on a successful percutaneous retrieval and redeployment of the device in such a situation, preventing any vascular injury or unplanned emergency open heart surgery.

ABSTRACT

Transesophageal echocardiography (TEE) is widely used in cardiac surgery. TEE provides important diagnostic and functional information before and after cardiopulmonary bypass thereby having a very important impact on perioperative clinical outcomes. We describe a case in which intraoperative TEE was instrumental in the timely diagnosis of inadvertant closure of the inferior vena cava (IVC) opening during minimally invasive surgical closure of atrial septal defect.

ABSTRACT

Six female patients aged from 19 to 73 years, with ostium secundum atrial septal defect underwent closure procedure with Amplatzer septal occluder device. Three-dimensional Echocardiography [3D-TEE] was done during the procedure or one day after the procedure. 3D-TEE provides incremental value over Two- dimensional trans-esophageal echocardiography in measuring Amplatzer septal occluder disc sizes and correlates well with manufacture device size. 3D-TEE will surely prove to increase the technical efficiency and it will become an important tool for the interventionists for periprocedural evaluation of device closures

ABSTRACT

FUNDAMENTO: A ecocardiografia bidimensional à beira do leito tem sido utilizada com sucesso para guiar a atriosseptostomia com cateter balão, agilizando o procedimento e evitando os riscos do transporte para o laboratório de hemodinâmica. OBJETIVO: Avaliar os resultados da atriosseptostomia com cateter balão à beira do leito em neonatos cianóticos. MÉTODOS: Entre jan/1997 e jul/2008, foram realizados 102 procedimentos de atriosseptostomia com cateter balão guiados pela ecocardiografia, sendo avaliados níveis de saturação, diâmetro da comunicação, saturação de oxigênio, resposta clínico-laboratorial e complicações relacionadas ao procedimento. RESULTADOS: De um total de 102 casos de Rashkind realizados à beira do leito, 98 preencheram os critérios de inclusão, sendo 90 neonatos do Grupo A (procedimento de Rashkind em fase pré-operatória) e 8 do Grupo B (procedimento em fase pós-operatória). Houve predomínio do sexo masculino (75 por cento), a idade média foi de 8,3 ± 9,3 dias, o peso médio foi de 3.100 ± 1.100 g e a transposição das grandes artérias foi a cardiopatia congênita mais frequente (n = 74). Comparando-se os valores das saturações pré e pós-procedimento (65,9 ± 19,5 por cento e 86 ± 9,7 por cento) e o diâmetro da comunicação interatrial pré e pós-procedimento (2,3 ± 1,0 mm e 5,5 ± 1,3 mm) houve diferença estatisticamente significativa (p < 0,001). Comparando-se os valores das saturações e o diâmetro da comunicação interatrial nos grupos de sobreviventes e não sobreviventes não houve diferença estatisticamente significativa (p > 0,05). CONCLUSÃO: A atriosseptostomia com cateter guiada pela ecocardiografia reduz os riscos por possibilitar a efetiva paliação sem perda de tempo em neonatos cianóticos, além de apresentar menores custos hospitalares.


BACKGROUND: The bedside two-dimensional echocardiography (2-D ECHO) has been successfully used to guide the balloon atrial septostomy, speeding up the procedure and preventing the risks of transportation to the hemodynamics laboratory. OBJECTIVE: To assess the results of the bedside balloon atrial septostomy in cyanotic neonates. METHODS: Between January/1997 and July/2008, 102 atrioseptostomies by balloon catheter guided by echocardiography were carried out and saturation levels, defect diameter, oxygen saturation, clinical-laboratory response and complications related to the procedure were evaluated. RESULTS: Of 102 cases of bedside Rashkind septostomy, 98 met the inclusion criteria, with 90 neonates in Group A (Rashkind procedure in the preoperative phase) and 8 in Group B (procedure at the postoperative phase). There was a predominance of the male sex (75 percent), mean age was 8.3 ± 9.3 days and the mean weight was 3,100 ± 1,100 g; the transposition of the great arteries was the most frequent congenital heart disease (n = 74). When comparing the levels of saturation pre and post-procedure (65.9 ± 19.5 percent and 86 ± 9.7 percent) and the diameter of the interatrial septal defect pre and post-procedure (2.3 ± 1.0 mm and 5.5 ± 1.3 mm) there was a statistically significant difference (p < 0.001). When comparing the levels of saturation and the diameter of the interatrial septal defect between the group of survivors vs non-survivor, there was no statistically significant difference (p > 0.05). CONCLUSION: The balloon atrial septostomy guided by the echocardiography reduces the risks by allowing the effective palliative procedure to be carried out promptly in cyanotic neonates, in addition to presenting lower hospital costs.

ABSTRACT

El infarto cerebral durante el embarazo o puerperio es una complicación grave que causa alta morbimortalidad materna. Presentamos el caso de una mujer previamente sana, de 32 años de edad, que sufrió embolismo cerebral posparto. La ecocardiografía confirma la presencia de foramen oval permeable, que puede ser causa de embolismo paradójico, causando un accidente vascular cerebral transitorio o infarto. Para prevenir episodios recurrentes de embolismo cerebral durante el embarazo, parto o puerperio, se realizó el cierre intervencional del foramen oval sin complicaciones.


Stroke during pregnancy and puerperium is a severe complication that causes high morbidity and mortality. We report a case of previously healthy, 32 year old woman, who suffered cerebral embolism after delivery. Echocardiography confirmed the patent foramen ovale. Patent foramen ovale may be a mechanism of paradoxical embolism causing a transient ischemic attack or stroke. To prevent recurrent cerebral embolism during pregnancy, delivery and puerpuerium, interventional closure of the patent foramen ovale was performed. The postinterventional course was uneventeful.

ABSTRACT

Antecedentes: El foramen oval permeable (FOP) es un hallazgo frecuente en pacientes con accidente vascular encefálico criptogénico (AVEC), y se discute la utilidad de su cierre percutáneo (CP). Objetivo: Evaluar el riesgo de recurrencia de eventos neurológicos en pacientes con AVEC y FOP, y compararlos entre aquellos tratados médicamente y los sometidos a CP. Métodos: Entre los 106 pacientes admitidos por AVEC y FOP, en el período 2003 a 2006, determinamos la aparición de nuevos eventos neurológicos isquémicos (NEN), y estudiamos sus factores determinantes y comparamos los que se sometieron a CP versus lo que continuaron con tratamiento médico, según criterio del tratante. Se consignaron las características clínicas y de la antomía del FOP en el ecocardiograma Los NEN se confirmaron por examen neurológico y/o neuro-imágenes. Para el análisis de los datos se utilizó chi-cuadrado y regresión logística.Resultados: Entre los 106 pacientes evaluados, 87 siguieron tratamiento médico y 19 CP. Los pacientes sometidos a CP presentaban mayor asociación de FOP con aneurisma del septum interauricular (ASI) (57,9% versus 35,6%, p=0,05). El seguimiento fue de 27 +/-13 meses. En este período se demostró un 12,6% de nuevo evento neurológico entre los tratados médicamente, mientras que ninguno lo presentó entre los sometidos al CP (NS). El único predictor independiente para NEN fue el ASI asociado con FOP; OR: 8,45 (1,56-60,46). Conclusiones: De acuerdo a nuestros resultados, los pacientes con AVEC y FOP tienen alto riesgo de recurrencia cuando el FOP se asocia a ASI y aparentemente se benefician con CP.


Background: Patent Foramen Ovale (PFO) is a frequent finding in patients with cryptogenic stroke (CS). Theeffect of closing the PFO in this setting is debated. Aim: to evaluate de risk of stroke recurrence in patients with CS and PFO; to compare this risk in patients followed under medical treatment with those undergoing percutaneous closure of PFO. Methods: From 2003 to 2006, 106 patients were admitted with a CS and the presence of PFO was documented by echocardiography. New ischemic strokes and risk factors were compared between those who weresubmitted to percutaneous closure of PFO and those treated in a conventional way. The decision to close thePFO was taken by the physician in charge. Clinical findings and echocardiographic characteristics of thePFO were recorded. New ischemic events were diagnosed by neurologic assessment and/or imaging techniques. Data was analyzed by chi square testing and logistic regression. Results: 87 patients were followed under medical treatment and 19 had closure of the PFO. The latter group had a greater incidence of atrial septal aneurysm (57.9% vs. 35.6%, p=0.05). The mean follow up was 27 +/- 13 months.New ischemic stroke occurred in 12.6% in the medically treated group while none was observed in the PFO closure group (NS). The sole independent predictor of new stroke was the presence of atrial septal aneurysm (OR: 8.45, 95% C.I. 1.56 - 60.46) Conclusion: Patients with CS and PFO are at considerable risk of developing new strokes, especially those with concomitant atrial septal aneurysm. Closure of PFO was apparently useful to prevent this risk.

ABSTRACT

Elegir el tratamiento de la comunicación interauricular tipo ostium secundum (CIA) y del ductus arterioso permeable (DAP), antes patrimonio exclusivo de la cirugía, requiere valorar cuidadosamente la ecuación riesgo/beneficio entre el cierre quirúrgico y el percutáneo. Mostramos nuestra experiencia de diez años del cierre percutáneo de la CIA y el DAP en dos poblaciones: a) 75 pacientes con CIA (de 16 meses a 56 años y peso mínimo de 8,5 kg). En 72 pacientes el cierre fue total (uno presentó una insuficiencia mitral mínima y otro una hemiparesia postprocedimiento inmediato, ambas transitorias, sin secuelas). En tres pacientes el cierre no fue posible por dificultades en el anclaje de los dispositivos, los cuales fueron extraídos sin complicaciones. b) 275 pacientes con DAP (2 meses a 54 años y peso de 3,2 a 79 kg). El cierre con coils fue total en 86,8% de los casos, 10% con intento fallido y derivados a cirugía, en 2,2% persistió un shunt residual leve, 1% fueron perdidos para seguimiento. Con el uso de los dispositivos Amplatzer PDA y Grifka se logró 100% de éxito. Complicaciones: embolización de coils hacia la arteria pulmonar o la aorta, extraídos todos, excepto tres (embolización en arterias pulmonares periféricas). No se presentaron complicaciones con el uso de dispositivos Amplatzer. El tratamiento de la CIA y del DAP por medio de dispositivos oclusores implantados por vía percutánea, en pacientes correctamente seleccionados, es un procedimiento sencillo, práctico, con excelentes resultados, breve período de internación y mínima agresión psicofísica.

ABSTRACT

OBJETIVO: Avaliar a efetividade da prótese de Amplatzer® para tratamento de comunicação interatrial tipo ostium secundum (CIA OS). MÉTODOS: Estudo de coorte histórica entre novembro de 1998 e setembro de 2005, em que foram realizados 101 procedimentos para oclusão percutânea de CIA OS em nossa instituição. Os procedimentos foram efetuados no laboratório de hemodinâmica, sob anestesia geral e com monitorização por ecocardiografia transesofágica (ETE). Os pacientes foram acompanhados clinicamente e com ecocardiografia em 30 dias, seis meses e depois anualmente. O resultados são apresentados em média, desvio padrão e porcentual, e a sobrevida livre de eventos foi estimada pela curva de Kaplan-Meier. RESULTADOS: Dos 101 pacientes, 60 (59,4 por cento) eram mulheres. As médias para idade, peso, altura, índice de massa corporal e superfície corporal foram, respectivamente, de 24,3 + 18,31 anos, 51,88 + 23,76 kg, 140,59 + 39,3 cm, 23,18 + 18,9 kg/m², e 1,24 + 0,21 m². A prevalência de aneurisma do septo interatrial foi de 4,95 por cento, e 98 casos eram de defeito único. O diâmetro das CIAs foi de 21,47 + 6,96 mm pela angiografia e de 21,22 + 7,93 mm pela ETE. As próteses implantadas mediam 23,92 + 7,25 mm, variando de 9 mm a 40 mm. O tempo de procedimento foi de 90,47 + 26,67 minutos e a média de internação hospitalar, de 2,51 + 0,62 dias. Os seguimentos clínico e ecocardiográfico ocorreram com 12,81 + 8,41 meses e todas as próteses estavam bem ancoradas e sem shunt residual. O sucesso do procedimento foi de 93 por cento (94/101). Em cinco casos não se conseguiu liberação adequada do dispositivo e dois pacientes apresentaram CIA residual. Não foram registradas complicações maiores. CONCLUSÃO: A prótese de Amplatzer® mostrou-se efetiva para o tratamento percutâneo de CIA OS.


OBJECTIVE: To evaluate the effectiveness of the Amplatzer™ septal occluder in the treatment of ostium secundum atrial septal defects (OS ASDs). METHODS: Retrospective cohort study conducted between November 1998 and September 2005 involving 101 OS ASD transcatheter occlusion procedures in our institution. All procedures were conducted in the hemodynamic laboratory under general anesthesia with transoesophageal echocardiographic monitoring (TEE). Clinical and echocardiography assessments of the patients were conducted at 30 days, six months and on an annual basis. The results are presented as averages, standard deviations and percentages. Event-free survival was estimated using the Kaplan-Meier curve. RESULTS: From the 101 patients, 60 (59.4 percent) were females. Mean age, weight, height, body mass index and body surface area were, respectively: 24.3 ± 18.31 years, 51.88 ± 23.76kg, 140.59 ± 39.3cm, 23.18 ± 18.9kg/m² and 1.24 ± 0.21m². The prevalence of interatrial septum aneurysms was 4.95 percent, and 98 cases had an isolated defect. ASD diameters were 21.47 ± 6.96mm using an angiography and 21.22 ± 7.93 mm using a TEE. The average size of the implanted devices was 23.92 ± 7.25mm, ranging from 9mm to 40mm. The procedure time was 90.47 ± 26.67 minutes and the average hospital stay was 2.51 ± 0.62 days. Clinical and echocardiography follow-up was conducted at 12.81 ± 8.41 months and all devices were securely anchored without any residual shunts. The procedure success rate was 93 percent (94/101). In five cases adequate deployment of the device was not possible and 2 patients presented residual ASD. No major complications occurred. CONCLUSION: The Amplatzer™ septal occluder is an effective OS ASD transcatheter treatment device.

ABSTRACT

Approximately 40 percent of ischemic strokes have no clearly definable etiology and are termed cryptogenic strokes. Patent foramen ovale, a small communication between the left and right atria, is considered to be a risk factor for cerebral embolism. In this study, we report the case of a 29-year-old woman with diagnosis of ischemic stroke due to patent foramen ovale who has undergone percutaneous endovascular closure. The aim of this report is to discuss the relevant aspects of the patent foramen ovale and the cryptogenic stroke, its clinical presentation, diagnosis, management and recurrence.


Aproximadamente 40 por cento dos acidentes vasculares encefálicos isquêmicos não apresentam etiologia definida e são classificados como criptogênicos. O forame oval patente, uma pequena comunicação entre os átrios direito e esquerdo, é considerado um fator de risco para embolismo cerebral. No presente artigo, relatamos o caso de uma jovem de 29 anos com o diagnóstico de acidente vascular encefálico isquêmico decorrente do forame oval patente que foi submetida ao fechamento endovascular percutâneo. O presente relato discute aspectos relevantes da apresentação clínica, diagnóstico, manejo clínico e recorrência desta condição.
