ABSTRACT

Fístulas de artérias coronárias têm incidência baixa, sendo diagnosticadas mais frequentemente pelo ecocardiograma ou angiotomografia coronariana, embora a cineangiocoronariografia seja o método padrão-ouro. Têm origem mais comumente na artéria coronária direita, sendo a drenagem para câmaras de baixa pressão o mais habitual. O tratamento pode ser expectante, cirúrgico ou percutâneo. Este relato descreve o caso de uma rara apresentação de insuficiência cardíaca, dada por fístula da coronária circunflexa com drenagem para o átrio esquerdo. (AU)


Coronary artery fistulas have a low incidence and are often diagnosed by echocardiography or coronary computed tomography angiography, although coronary angiography is the gold standard. They commonly originate in the right coronary artery, with drainage to low-pressure chambers being the most frequent finding. Treatment can be expectant, surgical, or percutaneous. This report describes a case of a rare presentation of heart failure due to a fistula of the circumflex coronary artery with drainage into the left atrium. (AU)

ABSTRACT

Coronary artery fistulae are abnormal connections between a coronary artery and any cardiac chamber or other vessels. Most of them have a congenital origin. We report a 60 years old woman referring a history of progressive dyspnea and orthopnea during the last year. A continuous heart murmur was audible in the third and fourth intercostal spaces at the left sternal border. Electrocardiogram was normal and echocardiography showed mild dilation of right cavities and an image suggesting a dilated right coronary artery with flow to right atrium. Coronary angiography was performed, showing a normal left coronary artery and a very large, tortuous right coronary artery with an extensive communication to coronary venous sinus. Surgical treatment was decided and was performed without incidents. The patient is well after five years of follow up.

ABSTRACT

O tratamento tradicional da fístula aorto-entérica secundária baseia-se na retirada cirúrgica da prótese, desbridamento aórtico, enxerto extra-anatômico, ou in situ, nos casos em que o campo cirúrgico apresenta-se sem sinais de infecção. Recentemente, alguns autores vêm preconizando o tratamento endovascular em pacientes instáveis e com alto risco cirúrgico. Apresentamos um relato de caso de paciente portador de fístula aorto-entérica secundária tratado inicialmente por via endovascular.


Traditional treatment of secondary aortoenteric fistula is based on open surgery followed by device removal, aortic debridement and extra-anatomic or in situ by-pass when no signs of local infection are found. Recently, some authors have been advocating endovascular treatment in unstable and high-risk patients. We present a case report of a patient who underwent initial endovascular treatment of a secondary aortoenteric fistula.

ABSTRACT

Relatamos o caso de um paciente do sexo feminino, assintomática, com grande fístula bilateral da artéria coronária-artéria pulmonar. O monitoramento clínico foi a opção escolhida para tratamento. Discutimos os pormenores das opções terapêuticas, enfatizando a tendência excessiva de utilizar a abordagem cirúrgica e a grande escassez de acompanhamentos clínicos de longo prazo em pacientes assintomáticos.


We report the case of an asymptomatic female patient, with a large non-complicated bilateral coronary-pulmonary artery fistula. Clinical monitoring was the choice of treatment. We discuss the therapeutic options in depth, emphasizing the excessive tendency of the surgical approach and the great scarcity of reports on long-term clinical follow-up in asymptomatic patients.

ABSTRACT

A fístula coronariana é uma anomalia caracterizada por comunicação entre uma artéria coronária e uma câmara cardíaca, artéria pulmonar, seio coronariano e veias pulmonares. Representa 0,2 por cento a 0,4 por cento das cardiopatias congênitas e 0,1 por cento a 0,2 por cento da população adulta submetida a angiografia coronariana. Relatamos o caso clínico de uma paciente com 64 anos, cuja anomalia foi diagnosticada durante investigação clínica por desconforto torácico, dispnéia e síncope, sendo indicada correção cirúrgica com abertura da artéria pulmonar através de circulação extracorpórea.


The coronary fistula is an anomaly characterized by the communication between a coronary artery and a cardiac chamber, pulmonary artery, coronary sinus and pulmonary veins. It represents 0.2 to 0.4 percent of the congenital cardiopathies and 0.1 percent to 0.2 percent of the adult population submitted to coronary angiography. We report the clinical case of a 64-year-old female patient, whose anomaly was diagnosed during a clinical investigation due to chest discomfort, dyspnea and syncope; the surgical correction was indicated, with opening of the pulmonary artery through extracorporeal circulation.

ABSTRACT

BACKGROUND: Transcatheter closure of coronary artery fistulas has emerged as a successful alternative to surgery. We describe various techniques and short-term findings in 15 patients who were taken up for transcatheter closure of these fistulas. METHODS AND RESULTS: Fifteen patients (aged 2-55 years; 12 males) with coronary artery fistulas underwent percutaneous transcatheter closure between June 1997 and December 2002. Site of origin of these fistulas were: right coronary artery in 7, left anterior descending coronary artery in 4, left main coronary artery in 2 and left circumflex coronary artery in 2 patients. Drainage site of these fistulas were: right ventricle in 9, right atrium in 4 and pulmonary artery in 2 patients. Out of these 15 fistulas, 14 were congenital and one was iatrogenically produced following inadvertent cutting balloon angioplasty of a septal perforator in a patient with chronic total occlusion of left anterior descending coronary artery. Various occlusion devices used to close these fistulas were: conventional metallic coils in 10, floppy tips of coronary angioplasty guidewires in 2, Amplatzer duct occluder in 1 and Amplatzer septal occluder in 2 patients. One of our patients had a coronary artery fistula draining by two openings into the right atrium, both of which were successfully closed using 2 Amplatzer duct occluders. Check angiogram after the procedure revealed complete occlusion in 13 (86.6%) and small residual flow in 2 patients. Follow-up studies at 3-55 months (mean 18 months) showed complete abolition of shunt in all patients with no evidence of recanalization leading to recurrence of shunt. CONCLUSION: Transcatheter closure of coronary artery fistulas is feasible and safe in the anatomically suitable vessels. Use of floppy tips of coronary angioplasty guidewires reduces the cost of the procedure significantly. which is an important consideration in developing countries like India.

ABSTRACT

Presentamos el caso clínico de un recién nacido de 35 semanas de gestación con sospecha prenatal de un tumor cerebral. El cuadro clínico del recién nacido orientó hacia una malformación arteriovenosa intracraneal lo que se demostró mediante ultrasonografía con Doppler color efectuada en la UTI neonatal. Se destaca la buena correlación diagnóstica con la arteriografía cerebral efectuada por cateterismo femoral que precisó la existencia de un fístula dural gigante, presentando los buenos resultados del tratamiento mediante embolización con microcoils, que permitió la sobrevida del niño con mínima secuela, a los dos años de seguimiento.

ABSTRACT

An acquired aortopulmonary artery fistula is rare. We describe a case with an aortic arch aneurysm communicating with the main pulmonary artery. The diagnosis was made on the basis of transthoracic echocardiography and confirmed by transesophageal echocardiography. A post-mortem examination revealed the complete anatomy of the aneurysm and the aortopulmonary communication.

ABSTRACT

We report here a case of coronary artery fistula in a neonate with clinical signs of heart failure. The electrocardiogram showed signs of left ventricular hypertrophy and diffuse alterations in ventricular repolarization. Chest X-ray showed an enlargement of the cardiac silhouette with an increase in pulmonary flow. After echocardiographic diagnosis and angiographic confirmation, closure of the fistulous trajectory was performed with a detachable balloon with an early and late successful outcome.

ABSTRACT

Con el propósito de describir las alteraciones en la función de la red vascular coronaria secundarias a las anomalías congénitas de las arterias coronarias, se presentan diez pacientes con fistulas congénitas de las arterias coronarias en los que se había realizado cateterismo cardiaco: tres casos con fistula arteriovenosa, dos con fistula arterioarterial, un caso de anastomosis de una rama terminal de la arteria coronaria en un espacio lacunarintramiocardico, un caso de anastomosis de la arteria coronaria derecha a la circunfleja, un caso con atresia valvular pulmonar y desvío de sangre de la cavidad ventricular hacia los sinusoides intramiocárdicos y arterias coronarias normales y dos casos con origen anómalo de una arteria coronaria en el tronco de la arteria pulmonar. La isquemia del miocardio en nueve de los casos, es debida principalmente al "robo" sanguíneo y a la pérdida de la estructura y función de los capilares; a la isquemia contribuye la dilatación de las arterias comprometidas con la fistula, que al formar un túnel o aneurisma aumentan su distensibilidad contribuyendo al incremento del "robo" sanguíneo. Dicha isquemia se agrava por la presencia de estenosis aterosclerosa coronaria

ABSTRACT

Reportamos el caso de una escolar femenina, 9 años, con hallazgo de fístula arterio-arterial sistémico-pulmonar. Como trayecto anómalo comunica la aorta descendente con la rama izquierda de la arteria pulmonar. Se trata de una malformación congénita aislada con una expresión clínica dada por la auscultación de un soplo continuo de acentuación sistólica en el área infraclavicular izquierda. Signos electrocardiográficos de sobrecarga diastólica del ventrículo izquierdo. El Doppler continuo demuestra un flujo turbulento sisto-diastólico en la rama pulmonar; dilatación de cavidades izquierdas con el ecocardiograma-bidimensional. Las radiografias torácicas muestran una sombra de aspecto hídrico paracardíaca izquierda con crecimiento hemicardio izquierdo. La cineangio reveló la emergencia del ramo anómalo, tortuoso y dilatado en sus extremos desde la aorta torácica, sin aspecto aneurismático. Paciente prácticamente asintomática salvo los hallazgos ya mencionados. Como opción terapéutica se plantea la ligadura y sección de la porción medial del trayecto vascular aberrante. Se analizan las diferencias con las fístulas arterio-venosas pulmonares
