Patients requiring coronary artery surgery may have had bilateral saphenous vein stripping, and the arm veins may not be adequate for use for coronary artery grafting. The internal mammary artery may not be long enough for use for the circumflex or right coronary artery anastomoses. A suitable substitute would be most welcome for these patients or for those(More)
Skeletonization of the internal thoracic artery during myocardial revascularization procedures may provide some degree of protection from sternal wound infection in diabetic, obese, or pulmonary compromised patients when both internal thoracic arteries are used as conduits. Prior descriptions of the technique fail to provide specific details and possible(More)
From 1970 to 1978, 61 patients were operated upon for mitral insufficiency secondary to coronary artery disease. These patients were between 44 and 71 years of age and all were in Class III or IV of the New York Heart Association Classification. The left ventricular end-diastolic pressure was 15 mm Hg or more in 32 of the 39 patients in whom it was(More)
Aluminum nitride (AIN) is a direct bandgap semiconductor with a bandgap about 6.1 eV at room temperature, the largest among semiconductors. This paper emphasizes experimental results of the growth and optical properties of AIN nanostructures by direct nitridation. The nitridation process was performed by chemical vapor deposition method with nitrogen (N2)(More)
Based on a Chemical Vapor Deposition (CVD) process, an alumina tube electric furnace was assembled to synthesize different one dimensional aluminum nitride (AIN) nanostructures via aluminum powder and nitrogen gas flow. The products obtained where nanowires, nanorods, a unique chain-linked nanocage structure made from an entanglement of AIN nanowires and an(More)
There are few published reports regarding the long-term results of the operative treatment of significant mitral insufficiency secondary to coronary artery disease. The few available reports deal with mitral replacement and myocardial revascularization. However, we prefer mitral repair to mitral replacement with myocardial revascularization. Eighty-seven(More)
