Avoidance of retrograde catheterization by Doppler echocardiographic diagnosis of Björk-Shiley aortic valve
1Section of Cardiology, University Medical Center, University of Arizona, Tuscon.
Abstract:
A 74-year-old man with a history of prior Björk-Shiley aortic valve replacement was admitted with chest pain and dyspnea. Results of physical examination and cinefluoroscopy suggested a dysfunction of the prosthetic valve; imaging echocardiography was not helpful. Nonimaging continuous wave Doppler examination confirmed severe prosthetic aortic valve dysfunction, necessitating emergent replacement, and potentially hazardous retrograde catheterization of the prosthesis was avoided.
