A preoperative diagnosis of valvular calcification that indicates advanced degeneration and implies potential immobility is now of more than academic interest. It is also of importance in uncovering aortic valvular disease that may contraindicate mitral commissurotomy. Surgical experience indicates that conventional roentgenography has a low positive yield. Fluoroscopy, in our hands, has a high positive yield but has the disadvantages of dependence upon individual interest and knowledge and of failure to provide a permanent record verifiable by others. In this study, planigraphy is demonstrated to be superior to all other methods described for the detection of intracardiac calcification.
