Résumé
Relatamos um caso de hipovolemia grave, acarretando obstrução dinâmica do trato de saída do ventrículo esquerdo, e grave regurgitação mitral. Após restaurada a normovolemia, essas anomalias foram completamente revertidas. Salientamos que diferentemente de outros casos, previamente relatados, o grau de regurgitação mitral em nosso paciente foi grave.

A 50-year-old man developed recurrent angina 1 year after coronary artery bypass surgery. The patient was found to have a large fistula involving branches of the internal mammary artery graft and the left pulmonary artery. In the absence of another clear cause for the patient's symptoms, we speculated that our patient's angina and abnormal stress nuclear study were due to coronary steal. In patients with a history of coronary bypass grafting, fistula formation between graft and native vessels should be considered as a possible cause of early recurrent angina
