[Carotid pulse curve in patients with prosthetic aortic heart valves (author's transl)]

The carotid pulse curve in 114 patients with prosthetic aortic heart valves showed the following characteristics: Porcine xenografts cause significant prewaves. Small sizes of all models show a comb-phenomenon, the percussion wave is late systolic mostly, and the hemodynamic quotient is higher than in larger sizes.
