Pulsus alternans is usually found in patients with reduced systolic ventricular function. We describe a patient with recurrent pulmonary edema, hypertension, bilateral renal artery stenosis, but with normal systolic function. Pulsus alternans was demonstrated in both pulmonary artery, right ventricle, and left ventricle pressures. After successful renal artery revascularization, the pulsus alternans disappeared. This case illustrates that pulsus alternans can be present with diastolic dysfunction of the left ventricle in the absence of systolic dysfunction.
