Abstract: | Fistula formation between a coronary artery bypass graft (CABG)and the pulmonary arterial circulation represents a rare cause
of recurrent angina in patients following bypass grafting. Therapy has traditionally involved surgical ligation by open thoracotomy.
We describe a case of left internal mammary artery–left upper lobe pulmonary artery fistula presenting as early recurrent
angina following CABG. The fistula was embolized using platinum coils, resulting in symptomatic relief and improvement in
myocardial perfusion on cardiac perfusion scintigraphy. Coil embolization should be considered a therapeutic option in patients
with coronary–pulmonary steal syndrome. |
