[Study of shunts using isotopic technics].
Isotopic techniques and in particular 99m Tc sequential angiography are accurate methods of assessing left-right and right-left intracardiac shunts. The results obtained are so reliable that these methods have become the investigation of choice for diagnosis and follow-up of intracardiac shunts in children and young adults, for post-operative control of repaired septal defects and for rapid diagnosis of asymptomatic murmurs. Radio-isotope methods are more accurate than oxymetry and in addition scintigraphy using a scintillation camera outlines the cardiac cavities and the site of left-right shunts may be localised in most cases. These methods have the advantage of being quick, non-invasive and less irradiating than oxymetry or conventional contrast angiography. The recent introduction of isotopes with very short half lives and radioactive gases probably heralds new advances in an already proven field.
