Dicrotic pulse observed in a patient with prolapse of the aortic valve without aortic regurgitation.

We describe a case of dicrotic pulse in a patient who exhibited marked prolapsed aortic cusp without aortic regurgitation. Echo-Doppler in the abdominal aorta showed deep reversal flow confined to early diastole. We conclude that this prolapse was the cause of the steep dicrotic notch and the dicrotic pulse, because of the concomitance of non-leaking aortic valves.
