Cell migration and chimerism after whole-organ transplantation: The basis of graft acceptance

Fluorescence properties and metabolic features of indocyanine green (ICG) as related to angiography.

Variations in the frequency of ventricular premature depolarizations (VPDs) were evaluated with three consecutive 24-hour long-term electrocardiography monitor recordings from 15 clinically stable patients with various cardiac disorders. Mean hourly VPD frequencies ranged from 37--1,801 per hour. Data were subjected to 4 and 5 factor nested analyses of variance. The extent of spontaneous variation in arrhythmia frequency that occurred in individual patients from day to day was 23%, between 8-hour periods within days was 29%, and from hour to hour was 48%. In addition, the variability between repeated three-day monitoring periods over time was quantified in five patients and found to be 37%. This analysis determined that to distinguish a reduction in VPD frequency attributable to therapeutic intervention rather than biologic or spontaneous variation alone required a greater than 83% reduction in VPD frequency if only two-24-hour monitoring periods were compared, and greater than 65% reduction if two 72-hour periods were compared. The limitations of routine 24-hour electrocardiographic monitoring must be considered in diagnostic and therapeutic decision-making.

Limitations of routine long-term electrocardiographic monitoring to assess ventricular ectopic frequency.

Normal ECG values were determined using computer-assisted measurement of the ECGs of 2,141 white children aged 0 to 16 years divided into 12 age groups.

To arrive at an accurate anatomic diagnosis in patients with complex cardiovascular malformations or abnormal position of the heart, the situs of the viscera, or more specifically, that of the atria, must be known. Since the situs of the atria always corresponds to that of the tracheobronchial tree, the latter is a very reliable indicator of visceral (atrial) situs. A chest roentgenogram taken in the anteroposterior or posteroanterior projection will show the anatomy of the air-filled trachea and main bronchi, thus indicating whether there is situs solitus, situs inversus or “situs ambiguus”. The latter term is introduced to indicate that in many patients with asplenia or polysplenia syndrome, the visceral situs cannot be determined because of symmetrical development of normally asymmetrical organs.

The radiographic appearance of the tracheobronchial tree as an indicator of visceral situs.

Hemodynamic observations in 15 cases of the Hunter-Hurler syndrome are reported. Required premedication was two to three times that usually needed. No major complications or deaths occurred. As a group, these individuals tend to have slight elevations of pulmonary artery pressures and more definite elevations of systemic arterial pressures. They generally have normal cardiac outputs and, thus, elevations of total systemic, total pulmonary, and pulmonary arteriolar resistances. In only one case was there clinical and angiocardiographic evidence of valvular involvement, that case having aortic insufficiency. In another case there was only angiocardiographic evidence of mitral insufficiency. Only one child was in congestive heart failure at the time of the study. There was no evidence of coronary artery disease. The ascending limb right ventricular pressure curve was frequently notched and the pressure rise time of the left ventricle (dp/dt) was low. No case had a congenital malformation of the heart. Those ...
