          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% a 0,4 % das cardiopatias congênitas e 0,1% a 0,2% 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.

          Translated abstract

          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% of the congenital cardiopathies and 0.1% to 0.2% 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.

          Coronary anomalies: incidence and importance.

          Most patients with coronary anomalies are asymptomatic. The knowledge of those variations could be important in regard to invasive catheter treatment or bypass surgery. In a retrospective study, the angiographic findings based on 4,016 patients (1985-1989) were analyzed concerning coronary anomalies and malformations. Of the patients studied, 39 (0.97%) had coronary anomalies, and in 26 of these patients it was an anomalous circumflex branch. In 14 cases, the circumflex branch arose from a separate origin in the left aortic sinus. In 11 patients the origin was from the proximal segment of the right coronary artery. A singular coronary artery was found in five patients, originating from the right aortic sinus in two patients and from the left aortic sinus in three patients. An origin of the left coronary artery from the pulmonary artery, a coronary fistula, or an origin of the left anterior descending coronary artery from the RCA could be found in only one patient. Unexpected findings during invasive procedures would suggest a possibly existing coronary anomaly, especially when main branches cannot be opacified by selective contrast medium injection.

              Fístula da artéria coronária: relato de três casos operados e revisão da literatura

              Fístulas das artérias coronárias têm incidência baixa entre as cardiopatias congênitas, muitas vezes assintomáticas, devendo ser suspeitadas quando há presença de sopro contínuo no precórdio. Podem apresentar sintomas de precordialgia ou insuficiência cardíaca e devem ser estudadas adequadamente para tratamento seguro, tanto cirúrgico como por cateterismo ou acompanhamento clínico. No presente trabalho são relatados três casos tratados por operação com resultado satisfatório e a literatura é revisada.
