It is important to evaluate the severity and extent of cardiac rejection in heart transplantations. Eight heterotopic heart transplantations using mongrel dogs were performed, and gated magnetic resonance imaging (MRI) of the donor hearts was carried out. High signal intensity was obtained in the rejected myocardium at the time of cardiac rejection,(More)
It is important in heart transplantation to evaluate precisely the extent and location of cardiac rejection. At present, right ventricular endomyocardial biopsy has been used as the gold standard, however, establishment of noninvasive, simple, and easy diagnostic procedure is desired. The canine donor heart, in which atrial septal defect and tricuspid(More)
We have developed an automatic left ventricular assist device (LVAD) system which can maintain the normal circulation irrespective of severity of the LV failure (LVF) and can restore the failing heart by decreasing the bypass flow (BF) through the LVAD as the heart recovers. The main parts of our control-drive unit are an automatic ECG synchronization(More)
It is important to evaluate the severity and extent of cardiac rejection in heart transplantation. Six heterotopic heart transplantation models in the peritoneal cavity were prepared with 12 adult mongrel dogs and in vivo imaging of the donor heart was performed using gated magnetic resonance imaging, (MRI) and Gd-DTPA contrast enhancement. In cardiac(More)
We recently adopted the Rastelli operation as a one stage anatomical correction for three infants with transposition of the great arteries and associated with ventricular septal defect (TGA+VSD). In all, ventricular septal defect was enlarged by excision of the conus septum to avoid obstruction of intraventricular tunnel and Hancock valved conduits of 18 mm(More)
