Patients with symptoms of cerebral ischemia are often evaluated with
non-invasive carotid artery testing. An abnormal carotid Doppler ultrasound
frequency shift pattern of early systolic flutter (ESF) was demonstrated by
auscultation and velocity wave form analysis in patients with normal
carotid bifurcations. Ten of these patients were studied with
echocardiography (echo) and eight had mitral valve prolapse (MVP). To
evaluate the association between ESF and MVP, a prospective blinded study
was performed, recording carotid Doppler frequency shift in 50 patients
referred for routine echocardiography. A total of 18 patients had ESF: 9/12
patients with MVP by echocardiography had ESF. Nine additional patients
without MVP had ESF (two with mitral regurgitation and two with redundant
mitral valves). The association of ESF with MVP was significant (p less
than 0.001). The findings of ESF with a normal carotid artery by
non-invasive testing suggests a possible mitral valve origin for symptoms
of cerebrovascular disease.
