• Roentgenographic evidence resembling a mediastinal tumor or coarctation of the aorta might, after careful study, prove to be a kinking of the aortic arch. Ten cases of this particular aortic deformity have been observed at the Mayo Clinic, four diagnosed in retrospect. Nine of the 10 patients had systolic murmurs at the base of the heart, probably the result of turbulence of blood in the region of the aortic kink. Oblique and lateral roentgenograms will usually allow the diagnosis of kinking, and confirmation can be had through angiocardiography.
