Bedside evaluation of heart tracking in the postoperative patient.
A device to track and record the motion of the left ventricular border of the heart has been designed and is undergoing validation in human beings. The system involves the use of track-while-scan-techniques applied to video signals from a fluoroscope image intensifier. Results of studies obtained from the animal laboratory as well as from human beings indicate good correlation with standardized contractility indexes as well as with systolic time intervals, an alternative noninvasive technique.

Unusual complication of nasogastric esophageal intubation-erosion into an aberrant right subclavian artery.
The case history is presented of a seventeen year old female with a complicated postoperative course following a cesarean section. The patient expired following a massive upper gastrointestinal hemorrhage secondary to erosion of an indwelling nasogastric tube through the esophagus into an aberrant right subclavian artery. Emphasis is placed on an aggressive diagnostic approach to this problem using endoscopy.
