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 had no further thrombotic events since anticoagulant therapy was(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)
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)
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)
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)
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)
