A 56-year-old woman with moyamoya disease presented with angina pectoris. Coronary artery stenosis of atherosclerosis origin was resistant to repeated transluminal angioplasty. Coronary artery bypass grafting was performed by minimal invasive direct coronary artery bypass (MIDCAB), avoiding cardiopulmonary bypass and intraoperative hypotension. Since(More)
A massive hemothorax from a ruptured bronchial artery aneurysm (BAA) is very rare. Only 12 cases of ruptured mediastinal BAA have been reported. This case study describes a 77-year-old female with bronchiectasis who presented with anemia, hypertension, hemothorax, and a mediastinal mass. A chest tube was inserted through which 2 liters of unclotted blood(More)
BACKGROUND Although several techniques for coronary artery bypass grafting have been introduced that incorporate coronary endarterectomy (CE), there is little information about late patency among the various CE methods. To clarify the quality of CE, we assessed clinical and angiographic results of our experience with this procedure on 127 patients who had(More)
OBJECTIVE This study evaluates whether patients with coronary artery disease and severely depressed left ventricular ejection fraction (LVEF) benefit from complete revascularization by multivessel coronary artery bypass. METHODS From April 1994 to May 2002, 42 patients who underwent coronary artery bypass grafting (CABG) at our institution had impaired(More)
In embryology, a persistent connection of the left superior vena cava to the left atrium rarely coexists with a coronary sinus. We herein report an unusual case of persistent left superior vena cava terminating in a left atrium with normal coronary sinus, which was revealed at the time of permanent pacemaker implantation after a second operation for(More)
BACKGROUND We assessed the characteristics of composite branch conduits attached proximally to an in-situ left internal thoracic artery (LITA). METHODS Sixty nine patients underwent coronary artery bypass grafting (CABG) using composite branch conduits. Overall 35 distal LITAs, 4 RITAs, 18 radial artery grafts (RAG), and 13 inferior epigastric artery(More)
Although there are several mitral valve aneurysm reports, studies on aortic valve aneurysm are extremely rare. This paper describes an uncommon case of a large saccular aortic valve aneurysm associated with infective endocarditis. A 37-year-old man was hospitalized in our hospital with fever and dyspnea. Echocardiography found severe aortic regurgitation(More)
We sought to evaluate the safety and usefulness of deep hypothermic cardiopulmonary bypass with intervals of circulatory arrest for extensive thoracoabdominal aortic aneurysms. Between March 1994 and December 2002, 17 patients with Crawford type I and II were reviewed retrospectively. The patients were divided into two groups: group H (hypothermic(More)
