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)
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)
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)
AIMS In Japan, cancer is the most prevalent cause of death; the number of patients suffering from cancer is increasing. Hence, there is an increased burden on pathologists to make diagnoses. To reduce pathologists' burden, researchers have developed methods of auto-pathological diagnosis. However, virtual slides, which are created when glass slides are(More)
Cardiac papillary fibroelastoma is an uncommon tumor, and especially the one located in the left ventricular outflow tract wall is rare. The patient is a 69-year-old female. Multi-detector-row computed tomography (MDCT) revealed a 20×15 mm tumor attached to the left ventricular outflow tract wall under the left coronary cusp. The tumor was surgically(More)
An important issue in motor learning/adaptation research is how the brain accepts the error information necessary for maintaining and improving task performance in a changing environment. The present study focuses on the effect of timing of error feedback. Previous research has demonstrated that adaptation to displacement of the visual field by prisms in a(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)
