Videodensitometry in the diagnosis of aortic incompetence.

The videodensitometer has been used in a group of 20 patients with aortic incompetence and incompetence combined with stenosis. The method appears effective in the preoperative evaluation of the valvular and ventricular function of the patient. It gives objective and probably more accurate information of the regurgitation fraction and the ejection fraction than the commonly used semiquantitative methods. The method is simple to use and needs no technical changes in the roentgen equipment.
