Nursing Care Plan – Coronary Artery Bypass Graft
March 5, 2012 · Leave a Comment
Coronary Artery Bypass Graft surgery is the most common type of cardiac surgery and the most common procedure for older adults. The occluded coronary arteries are bypassed with the client’s own venous or arterial blood vessel or synthetic grafts. The internal artery (IMA) is the current graft of choice because it has a 90% patency rate at 12 years after the procedure. The vessels to be bypassed should have proximal lesions occluding more than 70% of the vessel’s diameter but with good distal runoff. Bypass of less occluded vessels may result in poor perfusion through the graft and early obstruction. The procedure is most effective when good ventricular function remains and the ejection fraction is more that 40% to 50%.
