[Function scintigraphy of the heart in patients with heart valve diseases].
In 58 patients suffering from either stenosis or insufficiency of a single heart valve, gated blood pool scintigraphy was performed to determine the ejection fraction as well as the peak filling and peak ejection rates. It could be demonstrated that in patients with valvular disorders the ejection fraction was only moderately decreased, generally remaining in the lower reference range. The peak filling and ejection rates showed no pathologic changes with the exception of patients with aortic regurgitation where these rates were significantly decreased. Thus, the estimation of left ventricular peak filling and ejection rates may permit diagnosis of myocardial impairment in patients with valvular disease even under resting conditions.
