[Catheterization in orificial aortic stenosis]

By virtue of its relative simplicity and its rapidity, the investigation of aortic stenosis recently perfected (and used with a satisfactory percentage of success and without important incident) deserves wide usage in haemodynamic and angiograpnic laboratories. Even if it does not always provide the solution to a particularly delicate problem, which is often of vital importance, it provides data which, modifiable and better used, should provide an adequate notion of the anatomical and physiopathological state in aortic stenosis.
