Endovascular control of patent internal thoracic artery graft in aortic valve surgery.

Aortic valve replacement in patients who underwent previous coronary artery bypass with a patent internal thoracic artery is often a challenge because of the risk of graft injury during dissection or difficulties to obtain optimum myocardial protection. Different approaches to myocardial protection or internal thoracic graft dissection and control have been described. Endovascular control of the internal thoracic graft by an angioplasty balloon catheter positioned in the operating room before the operation can be a safe and simple alternative. We report the case of a patient who underwent this technique for aortic valve replacement.
