Oximetric detection of intracardiac left-to-right shunts.
To assess prevailing guidelines for the oximetric detection of intracardiac left-to-right shunts, we examined the variability of right heart oxygen saturation step-ups in 1121 catheterisations in children with aortic and pulmonary stenosis, who were studied as part of the joint study of the natural history of congenital heart defects. It is estimated that in the absence of intracardiac shunting...

متن کاملRadionuclide quantitation of right-to-left intracardiac shunts in children.
A simple, noninvasive method for measurement of right-to-left intracardiac shunts would enhance the management of patients with congenital heart disease. This study describes application of data processing techniques used previously in dye-indicator curves to data recorded during the initial transit of radioactive bolus through the central circulation. Radionuclide angiocardiograms were perform...
متن کاملKrypton-85 in the Detection of Intracardiac Left-to-right Shunts.
ANUMBER of methods have been developed for detecting left-to-right shunts during cardiac catheterization of which the most frequently employed is determining the difference in oxygen saturations. This method has limited application in the presence of small shunts, however, since the minimal changes are often within the error of this method.' Therefore, other more sensitive technics have been em...
متن کاملBedside nuclear probe for detection and quantification of left to right intracardiac shunts.
A cadmium telluride nuclear probe with an Elscint gamma camera was used to detect and measure left to right intracardiac shunts at the bedside in 34 patients. Fifteen also had right heart catheterisation and oximetric measurement of the shunt. For the nuclear technique 740 MBq (20 mCi) of technetium-99m pertechnetate was injected into the right antecubital vein and the pulmonary to systemic flo...
