Composite graft replacement for the treatment of aneurysms of the ascending aorta associated with aortic valvular disease.

abstract：BACKGROUND:Coronary revascularization with bypass has been shown to improve survival in patients with coronary artery disease and left ventricular dysfunction. In these patients, use of nonsurgical revascularization with percutaneous transluminal coronary angioplasty (PTCA) is increasing, although their long-term outco...
