The BVE device is intended to assess mean peripheral pressure, vascular reserve, Cuff free Ankle Brachial Index (ABIm), and assess the presence or absence of hemodynamically significant arterial disease. By converting Doppler shifts to a blood pressure measurement, BVE can be used to monitor PAD in a non-invasive manner without confounding by arterial calcification.~This is a post-market, interventional, prospective, multi-center, open-label, non-randomized, single-arm clinical investigation designed to evaluate the clinical equivalence of BVE to arterial Duplex in a group of patients referred for evaluation of PAD of the limbs when performed by a vascular specialist. Moreover, the evaluation of the clinical performance including inter-operator variability and BVE non-diagnostic rate will be also carried out as exploratory variables.~Primary objective:~Evaluate the clinical equivalence (assessment of accuracy) of BVE as binary result (either presence or absence of significant peripheral arterial disease) compared to arterial duplex ultrasound in a group of patients referred for evaluation of PAD of the lower limbs when performed by a vascular specialist.~Secondary objectives:~Evaluate the clinical equivalence (assessment of accuracy) of BVE as binary result (either presence or absence of significant peripheral arterial disease) compared to ankle brachial pressure index (ABPI) in a group of patients referred for evaluation of PAD of the lower limbs when performed by a vascular specialist.~Assess the safety of the BVE device.~Exploratory objectives:~Evaluation of the BVE System for clinical performance including time needed to perform BVE, inter-operator variability and number of BVE non-diagnostic tests.
This is a BlueDop Vascular Expert System (BVE) Post-Market Clinical Follow-Up (PMCF) study. The primary objective of the study is to assess the clinical applicability and diagnostic accuracy of the BVE device in subjects who require an arterial duplex test due to suspected peripheral arterial disease (PAD).
