Suspected dysfunction of a Starr-Edwards aortic prosthesis implanted 33 years ago: the role of exercise stress echocardiography. Case report.

The authors present a case report of suspected dysfunction of a Starr-Edwards mechanical aortic prosthesis implanted in 1972. Its characteristic longevity, but also its disadvantageous hemodynamic profile, are discussed. Treadmill exercise echocardiography, whose role has yet to be clarified in the study of valve prosthesis, was used in the evaluation of the patient.
