[Bilateral congenital coronary-pulmonary artery fistulas; report of a case].

Bilateral coronary-pulmonary artery fistulas are very rare. We report a case of a 68-year-old woman without any previous medical history, who presented to our hospital after slow onset of chest heaviness on exertion. Coronary computed tomography (CT) and angiography revealed 2 fistulas:one arising from the left anterior descending artery accompanied by an aneurysm and the other from the right coronary artery. We opened the trunk of the pulmonary artery under cardio-pulmonary bypass and cardiac arrest. We recognized the outflow of the shunt just above the right pulmonary cusp, which was closed from the outside. We also closed the aneurysm of the shunt. Neither the fistulas nor the aneurysm was recognized by postoperative CT. The chest symptom disappeared.
