Out of 1,400 Holter ECGs, 15 records revealed arrhythmias which would be responsible for faint attack, including 8 sick sinus syndrome with cardiac arrest, 4 non-sustained ventricular tachycardia (VT), 2 paroxysmal atrial fibrillation and 1 paroxysmal supraventricular tachycardia. All of cardiac arrest corresponding to faint attack lasted for longer than 4(More)
A 70-year-old woman was found to have new heart systolic murmur and was transferred to our hospital for the treatment of high fever and dyspnea. The chest X ray showed cardiomegaly (CTR 63%) and marked pulmonary congestion. The UCG revealed that there was no evidence of infective endocarditis, but there was hypertrophic obstructive cardiomyopathy with the(More)
A 61-year-old Japanese woman with chronic renal failure suddenly became silent at the end of hemodialysis. On a neurological examination, she was unable to respond to one-step commands, state the names of objects, repeat single words, read words aloud or write her name. Because she exhibited no paralysis of the extremities, we diagnosed her as having global(More)
A sixty-year-old man was admitted to our hospital due to prolonged left anterior chest oppression and hypotention. The electrocardiogram revealed acute inferior myocardial infarction, confirmed by the coronary angiography which showed occluded right coronary artery (RCA) at the segment 4AV. The intra-coronary pro-urokinase infusion and coronary angioplasty(More)
A 51-year-old man with annuloaortic ectasia and aortic regurgitation, who did not have Marfan syndrome, underwent an aortic valve-sparing root reconstruction (remodeling). All three sinuses were excised and then the ascending aorta was replaced with a 30 mm collagen-impregnated Dacron graft, one of which ends were scalloped to reproduce pseudosinus. Each(More)
We present herein the case of a 63-year-old man with nephrotic syndrome who developed an apical infarction 4 days after undergoing coronary artery bypass grafting. Echocardiography done 2 weeks postoperatively revealed a left ventricular thrombus which was successfully removed. He has no further thrombotic events since anticoagulant therapy was initiated.
We describe a rare case of de novo acute myelogenous leukemia with trilineage myelodysplasia (AML/TMDS) associated with t(8;21)(q22;q22). The patient was admitted to our hospital with leukocytopenia. AML/TMDS was diagnosed by excess myeloblasts and morphological findings of bone marrow. The karyotype revealed 45, X, -Y, t(8;21)(q22;q22) in 17 of 20 analyzed(More)
Bilateral optic neuropathy with bilateral putaminal lesions may be caused by methanol or cyanide poisoning or mitochondrial disorders including Leber hereditary optic neuropathy and Leigh syndrome. We report the case of a 34-year-old Japanese man who developed bilateral visual loss 5 days after the development of gastrointestinal symptoms. Magnetic(More)
For studying the effect of regional myocardial blood flow changes on the epicardial ECG of right and left ventricular walls under acute right ventricular pressure overload, we mapped the epicardial using 64-channel shock electrodes, and estimated the myocardial blood flow with radioactive microspheres. In 9 anesthetized open-chest dogs, the main pulmonary(More)
