title: Radiologic detection of aortic stenosis.
abstract: Preoperative chest films of 100 consecutive patients with valvular aortic stenosis, referred to surgery, were evaluated. Aortic valve calcifications were the most common radiologic indicator of the disease, visible on the lateral chest film in 91 per cent of the cases notwithstanding high kV technique (170 kV). Poststenotic dilatation of the aorta appeared in only 36 per cent, unquestionable left ventricular enlargement in 52 per cent. It is concluded that, by paying attention to valve calcifications also when the aortic stenosis is not yet suggested clinically, the radiologist may contribute to timely diagnosis which may prevent unnecessary suffering or death. Difficulties in detection and possible confusion of aortic valve calcification with normal structures are discussed.
