Abstract:
When performing aortic valve replacement (AVR) in patients with a past history of coronary artery bypass grafting (CABG) using the internal thoracic artery (ITA), the patent ITA graft needs to be detached from the surrounding tissue and occluded to properly protect the myocardium. However, detaching the ITA graft from the surrounding tissue takes time, and caution must be exercised to avoid damaging the graft. Two patients with a past history of CABG using the ITA were scheduled to undergo AVR. To simplify AVR, a balloon was placed preoperatively, and was inflated during aortic occlusion to occlude the ITA graft. The myocardium was adequately protected in this manner. Furthermore, since adhesion detachment was limited to around the ascending aorta, operative duration was short and bleeding volume was low. Balloon occlusion of the ITA graft appears to be useful in reducing the invasiveness of AVR in patients with a past history of CABG.
