Objectives:

The Vicorder is a new brachial cuff-based device that estimates central blood pressure (cBP) using a brachial-to-aortic transfer function. The aim of this study was to evaluate cBP estimated by the Vicorder.

Methods:

During cardiac angiography, cBP estimated by the Vicorder and the SphygmoCor was evaluated against simultaneous invasive cBP in 50 patients. The two devices were also compared noninvasively in a separate group of 90 healthy individuals.

Results:

Central SBP (cSBP) obtained with each device satisfied the American Association for the Advancement of Medical Instrumentation accuracy criteria when peripheral waveforms were calibrated to invasive mean arterial pressure (MAP)/DBP: estimated− invasive cSBP difference,− 4.0±7.4 mmHg, Vicorder, P< 0.001;− 1.4±7.9 mmHg, SphygmoCor, P= 0.21. When oscillometric brachial SBP/DBP was used for peripheral waveform calibration, cSBP …
