A 76-year-old woman presented with shortness of breath and dyspnea after the intake of meals. Chest X-ray showed pulmonary congestion and pleural effusion. Computed tomography disclosed a hiatus hernia. Echocardiography demonstrated that the motion of the posterior wall in the left ventricle (LV) was paradoxically by the hiatus hernia, although LV ejection(More)
1. Cardiac activities of male and female spawning chum salmon were recorded simultaneously by using a radio telemetry system in combination with a wired system. 2. Heart beat stopped during a spawning bout for about 10 sec in female and for 4-6 sec in male. 3. Just before and after the temporary cardiac arrest, heart rate increased from the usual rate,(More)
BACKGROUND Effective alternatives to surgical myectomy for patients with symptomatic hypertrophic obstructive cardiomyopathy (HOCM) remain unestablished. Dual-chamber (DDD) pacing was evaluated in these patients using right atrial (RA) and epicardial left ventricular (LV) leads. METHODS AND RESULTS In 6 patients with HOCM refractory to medical therapy and(More)
The Terumo Capiox centrifugal pump system possesses an automatic priming function in which the motor repeatedly stops and runs intermittently to eliminate air bubbles in the circuit through the micropores of the hollow-fiber membrane oxygenator. By modifying this mechanism, we have developed a pulsatile flow mode. In this mode, maximum and minimum pump(More)
The 60-year-old women who complicated by multiple sclerosis was referred to our hospital under diagnosis of mitral valve stenosis and tricuspid valve regurgitation. The mitral valve replacement and the tricuspid valve annuloplasty were performed under cardiopulmonary bypass. In the state of multiple sclerosis, even an operation by general anesthesia could(More)
A 63-year-old man with chest pain at rest was referred to our hospital. Transthoracic echocardiography showed a mobile ball-like mass at the top of the right coronary cusp. Subsequently, transesophageal echocardiography also showed a mobile mass at the right coronary cusp. Aortic valve replacement with a mechanical valve was performed under general(More)
We developed a new data archive system for stone monuments, which includes image processing tools for images of the text on the monuments. We can store and search the algorithms of the image processing as well as the images and data of the samples to the system. We could obtain the text image of the stone monuments with simple image processing, and(More)
The effect of high dose tranexamic acid on blood loss after operations for acute aortic dissection was evaluated. Twenty-eight patients undergoing emergent operations for acute aortic dissection were studied. There were two groups, group T with 13 patients (group T) who were given 7 g of tranexamic acid after induction of anesthesia and 3 g of it after CPB(More)
A 53-year-old woman with a double, double, double (DDD) pacemaker due to complete atrioventricular block was admitted to our hospital with a diagnosis of congestive heart failure. At the time of admission, she was in a hypoxic state with cyanosis and clubbed finger. The ultrasonic cardiogram showed a severe degree of tricuspid valve regurgitation and a thin(More)
This report describes a technique for repairing an aortic stenosis in an elderly patient with a small aortic annulus and a narrow left ventricular outflow tract. Preoperative echocardiography in an 80-year-old woman showed severe aortic stenosis with a narrow outflow tract: the aortic valve area was 0.48 cm(2), the aortic annular diameter was 14 mm, and the(More)
