We used the Fogarty 2Fr IMAG Kit® on 14 patients who underwent aorto-coronary bypass grafting. The free flow of the left internal thoracic artery (LITA) after dilatation using Fogarty balloon catheter was 7.4 times greater than before dilatation. There was no statistical differences in catecholamines used postoperatively and postoperative cardiac output in the groups of cases with and without dilatation. String sign was appeared in 4 patients with dilatation of LITA. Fogarty balloon catheter save effective dilatation of LITA in certain selected cases.
