Detection of Pulmonic and Tricuspid Valvular Regurgitation by Means of Indicator Solutions
The presence of pulmonic and tricuspid valvular regurgitation may often be suspected from careful clinical examination. However, the validity of the generally accepted clinical criteria remain to be established by technics that permit the direct demonstration of reverse flow across these valves during life. This has been made possible by the detection of cardiogreen and of radioactive krypton (Kr85) in the right atrium or right ventricle after injection of these substances into a distal chamber.
