Dicrotic pulse due to prolapse of the aortic valve

without aortic regurgitation

Shinsuke Moriya , Kanji Iga and Takashi Konishi

Summary

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