Résumé

Abstract Fistula from left internal mammary artery (LIMA) to pulmonary artery (PA) is rarely encountered in daily practice. In recent years, endovascular therapy options have emerged for the treatment of fistula formations and replaced with surgery. A 53-year-old man admitted to our outpatient clinic with symptoms of typical angina and shortness of breath despite optimal medical therapy. In his relevant history, he had a coronary artery bypass graft (CABG) operation in 2009 in which his LIMA was anastomosed to left anterior descending (LAD) and ramus artery sequentially. Coronary angiography including selective imaging of LIMA demonstrated a fistula formation originating from the proximal portion of the LIMA and draining to PA. After successful closure of fistula with transcatheter coil embolization, the patient was discharged without any complication and symptom. In conclusion, although LIMA to PA fistula is an infrequent clinical condition, it should be considered as a potential cause of persistent angina after CABG operation. Treatment options include conservative medical therapy, surgical ligation and endovascular interventions. The best therapy should be individualised for each patient in respect to patient's symptoms, surgical compatibility and anatomy of fistula.


Resumo A fístula da artéria mamária interna esquerda (AMIE) para a artéria pulmonar (AP) é raramente encontrada na prática diária. Nos últimos anos, opções de terapia endovascular surgiram para o tratamento de formações de fístula e foram substituídas por cirurgia. Um homem de 53 anos de idade, internado em nosso ambulatório com sintomas de angina típica e falta de ar, apesar da terapia clínica ideal. Em seu histórico relevante, ele teve uma cirurgia de revascularização miocárdica (CRM) em 2009, na qual sua AMIE foi anastomosada à descendente anterior esquerda (DAE) e à artéria ramus sequencialmente. A angiografia coronária, incluindo imagens seletivas da AMIE, demonstrou uma formação de fístula proveniente da porção proximal da AMIE e drenando para AP. Após o fechamento bem-sucedido da fístula com embolização transcateter com mola, o paciente recebeu alta sem qualquer complicação e sintoma. Em conclusão, embora fístula entre AMIE e AP seja uma condição clínica pouco frequente, deve ser considerada como uma causa potencial de angina persistente após a operação de revascularização do miocárdio. As opções de tratamento incluem terapia médica conservadora, ligadura cirúrgica e intervenções endovasculares. A melhor terapia deve ser individualizada para cada paciente em relação aos sintomas do paciente, compatibilidade cirúrgica e anatomia da fístula.

Résumé

We report on three cases of longstanding pulmonary tuberculosis patients with coronary to bronchial artery fistula (CBF) who presented with recurrent massive hemoptysis. The first and second patients died because of decreased functional pulmonary volume plus massive hemoptysis and cannulation failure of CBF due to hypovolemic vasospasm, respectively. When recurrent hemoptysis occurs despite successful embolization treatment, CBF should be considered as a potential bleeding source. Moreover, a coronary angiography should be performed, especially in patients with longstanding cardiopulmonary disease such as pulmonary tuberculosis.

Résumé

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.

Résumé

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.
