A Peculiar Radial Artery Pressure Waveform After Aortic Valve Replacement

A 35-YEAR-OLD man presented to the authors ’ institution with a 2-year history of progressive dyspnea on exertion. Transthoracic echocardiography revealed mild mitral stenosis and severe aortic valve regurgitation resulting from rheumatic heart disease. The left ventricle (LV) was dilated; ejection fraction was 45% to 50%. The patient was taken to the operating room for aortic valve replacement. Catheters were placed in the right radial and left femoral arteries for continuous monitoring of arterial pressure.
