OBJECTIVE Antegrade perfusion for type A acute aortic dissection prevents malperfusion and retrograde cerebral embolism during cardiopulmonary bypass. Prompt establishment of antegrade perfusion via ascending aorta may improve the surgical results of type A dissections, especially in the situations of hemodynamic instability. Thus, we evaluated the efficacy(More)
A 71-year-old Japanese woman with severe chest pain was diagnosed with Stanford type A acute aortic dissection. After 3 months of medical treatment, she was operated on under a diagnosis of dissecting aneurysm of the ascending aorta and severe aortic regurgitation.

Use of the saphenous vein in aorto-coronary bypass surgery for treatment of occlusive coronary artery disease is a well-established technique. Use of the mammary artery for the same purpose has also been favorably reported. This study was undertaken to determine whether a vein graft containing a valve would have an added advantage. A comparison of the(More)
In order to minimize the complications, we introduced the intrathoracic implantation method since 1976. Until 1988, 12 children underwent this method. A pacemaker generator was exchanged in 8 patients, 12 times, because of battery exhaust. Compared with the conventional method (abdominal wall implantation), the complications such as electrode fracture,(More)
