Normal resting hemodynamics after valve replacement do not ensure normal exercise responses; leaves open whether exercise testing alters management.
Does aortic or mitral valve replacement normalize rest and exercise hemodynamics in patients without coronary artery disease or left ventricular failure?
Despite normal resting hemodynamics after valve replacement, patients frequently exhibit exercise-induced pulmonary hypertension and abnormal left ventricular filling pressures that are not determined by prosthesis obstruction.
Inselmann et al. (2000) studied this question.
