The authors present a manubrium-sparing sternotomy technique for aortic valve replacement in patients who have undergone previous myocardial revascularization with both internal thoracic arteries. They have found that preoperative 64-multislice computed tomographic imaging facilitates surgical planning by delineating the course of patent grafts and, in particular, the relationship between the sternum and the right internal thoracic artery graft.

Abstract
The authors present a manubrium-sparing sternotomy technique for aortic valve replacement in patients who have undergone previous myocardial revascularization with both internal thoracic arteries. They have found that preoperative 64-multislice computed tomographic imaging facilitates surgical planning by delineating the course of patent grafts and, in particular, the relationship between the sternum and the right internal thoracic artery graft. A manubrium-sparing sternotomy can in such instances avoid injury to the right internal thoracic artery graft during both resternotomy and adhesion dissection, thus reducing surgical risk and operative time. © 2013 by the Texas Heart ® Institute, Houston.File | Dimensione | Formato | |
