“…Of interest, not all patients with significant AS demonstrate pulsus parvus et tardus 22. In fact, the carotid upstroke had been previously shown to be normal in half of patients with severe AS, and in only 7% undergoing cardiac surgery for AS 23 24.…”

Background Aortic stenosis (AS) is commonly associated with myocardial and systemic arterial dysfunction. We use a radial artery applanation tonometry (B-Pro) device to characterise the arterial pulse profile of patients with AS and compare them against controls. Methods The B-Pro device was applied on the left radial artery of 117 consecutive patients, where 21 patients had AS. Baseline clinical and echocardiographic characteristics were compared. Differences in arterial pulse pressure profile were quantified by means of univariate and multivariable analyses. Results The group with AS was older (74±14 vs 62±14 years, P<0.001) and had fewer males (38% vs 65%, P=0.025), while other baseline comorbidities were similar. From the arterial pulse profile, a higher systolic peak time (202±45 vs 152±49 ms, P<0.001), lower systolic upstroke gradient (0.35±0.10 vs 0.42±0.14 mm Hg/ms, P=0.022) and longer systolic component of the cardiac cycle (43%±7% vs 39%±5%, P=0.001) were independently associated with AS. Conclusion The B-Pro device allows for real-time microscopic arterial pulse waveform analysis. There are significant differences between the pulse profiles of patients with AS and controls. The prognostic implications of these differences warrant further study.

Personalized mobile medicine will continue to advance through the development of wearable sensors that can wirelessly provide pertinent health information while remaining unobtrusive, comfortable, low cost, and easy to operate and interpret. It is the intention that the sensor presented hereafter can contribute to such innovation. By applying a combination of emerging microfluidic and electronic technologies, a miniature, flexible, transparent, highly sensitive and wearable pressure sensor with microfluidic elements has been implemented, referred to as a microflotronic device. High sensitivity of 0.1 kPa(-1) and fast response time on the order of tens of milliseconds has been achieved on the microflotronic sensor design. Its sensitivity is among the highest in impedance-based flexible pressure sensors. Once configured into an array, the transparent device can be easily aligned over the target artery to measure blood pressure noninvasively and continuously. In addition, the ultraflexible and thin plastic construct of the microflotronic sensor (of 270 µm in height) can be worn comfortably for extended periods of time. Importantly, the proposed microflotronic sensor has been utilized to perform arterial tonometry with the capability of noninvasive monitoring of arterial blood pressure waveforms in a real-time and continuous fashion.

Do radial arterial pressure curves have diagnostic validity for identify severe aortic stenosis?

Abstract: Our study using the radial arterial curve validated a pulsus tardus as a diagnostic sign for severe AS, while the validity of a pulsus parvus as a diagnostic sign was not confirmed.
