| Abstract: | Criteria for selection of patients with aortic valve disease for cardiac catheterization are described, based on a study of 81 cases. Children with aortic stenosis warrant catheterization at the time when the clinical diagnosis is made, but in adults this examination may be deferred until symptoms appear or left ventricular hypertrophy is recognized. In patients with pure aortic insufficiency catheterization may be deferred until symptoms appear. When severe stenosis and insufficiency co-exist, the valve is usually heavily calcified. Thirty-seven per cent of patients with aortic valve disease have co-existing mitral lesions and these patients are usually women, are fibrillating and, as a rule, have atrial enlargement in contrast to those with aortic valve disease only. On rare occasions, patients with mitral valve disease have clinically silent but angiographically demonstrable aortic insufficiency; therefore, aortography should precede open-heart correction of a mitral lesion so as to detect minor degrees of aortic insufficiency. |
