Use of Amplified Sound Signal to Identify Presence of Carotid and Femoral Stenosis

Stopped early

Conditions studied: Carotid Stenosis, Femoral Arterial Stenosis, Carotid Bruit Asymptomatic, Carotid Murmur

In brief

The purpose of the study is to test a new amplified stethoscope(AudioDoc) that can detect the presence of bruit by using an acoustic signal to represent the bruit. This pilot study will address two questions: is there a detectable difference in recorded sound signal of carotid and femoral bruit when compared to sound signals captured when there is no bruit present; is the use of a visual recorded signal more accurate in identifying carotid and femoral bruit when compared to traditional auscultation with a regular stethoscope and ultrasound.
