“…Accumulating evidence suggests that BP and time position of DiN reflect the state of the cardiovascular system. Changes of DiN position has been reported in patients with various cardiovascular complications, such as hypertension, diabetes, and aortic stenosis, and they were modulated by NO bioavailability [ 14 , 15 , 16 , 17 , 32 ]. However, we suppose that recording of AnN and evaluating the DiN-AnN intervals in mmHg and in ms, together with characterization of the cross-relationships between DiN-AnN intervals and other HPs, will add better informative value of the cardiovascular condition than the evaluation of DiN alone.…”

“…These data can contribute to the characterization of the specific modes of action of bioactive substances. However, only a few hemodynamic parameters (HPs) of APW in different patho-physiological conditions have been characterized so far [ 9 , 10 , 11 , 12 , 13 , 14 , 15 , 16 , 17 , 18 , 19 , 20 , 21 ]. To our knowledge, except for our two recent studies [ 22 , 23 ], there was neither a detailed detection of anacrotic notch nor reports of the time dependence of the cross-relationships of HPs.…”

We characterized modes of action of NO-donor S-nitrosoglutathione (GSNO) and NO-synthase inhibitor l-NAME derived from dicrotic (DiN) and anacrotic (AnN) notches of rat arterial pulse waveform (APW) in the condition of increased/decreased NO bioavailability. The cross-relationship patterns of DiN and AnN with 34 hemodynamic parameters (HPs) induced by GSNO and l-NAME are presented. After GSNO bolus administration, approximate non-hysteresis relationships were observed in the difference between DiN–AnN (mmHg) blood pressure (BP) and other 19 HPs, suggesting that these HPs, i.e., their signaling pathways, responding to NO concentration, are directly connected. Hysteresis relationships were observed between DiN-AnN (mmHg) and other 14 HPs, suggesting that signaling pathways of these HPs are indirectly connected. The hysteresis relationships were only observed between the time interval DiN-AnN (ms) and other 34 HPs, indicating no direct connection of signaling pathways. The cross-relationship patterns of DiN-AnN (mmHg), but not DiN-AnN (ms), induced by l-NAME were in accordance to the increased NO bioavailability induced by GSNO. In conclusion, we found the non-hysteresis/hysteresis cross-relationship “patterns” of DiN-AnN intervals to other HPs in the presence of GSNO that revealed their direct or indirect signaling pathways connections. This may contribute to our understanding of biological effects of natural substances that modulate NO production and/or NO signaling pathways.

“…The ability of ultrafast ultrasound imaging to accurately evaluate the velocity of an elastic wave propagating at several meters per second within the arterial wall has been validated in vitro using the shear wave elastography with the same scanner used in our study (Couade et al, 2010; Maksuti et al, 2016). As well as with the shear wave elastography, PWV measurement is performed using tissue Doppler imaging on the entire length of the probe to track precisely the propagation of the pulse wave along the arterial segment and has already been used in human studies (Mirault et al, 2015; Marais et al, 2019).…”

AimsTo compare the carotid stiffness and flow parameters by ultrafast ultrasound imaging (UF), in bicuspid aortic valve (BAV) patients to first-degree relatives (controls).MethodsBAV patients (n = 92) and controls (n = 48) were consecutively included at a reference center for BAV. Aortic valve and ascending aorta were evaluated by echocardiography. Common carotid arteries were evaluated by UF with a linear probe. A high frame rate (2,000 frames/s) was used to measure the pulse wave velocity (PWV). The arterial diameter change over the cardiac cycle was obtained by UF-Doppler imaging. This allowed us to measure the distensibility and the maximal rate of systolic distension (MRSD). The wall shear stress (WSS) was measured based on the same acquisitions, by analyzing blood flow velocities close to the carotid walls.ResultsBAV patients had significantly larger aortic diameters (p < 0.001) at the Valsalva sinus and at the tubular ascending aorta but no larger carotid diameters. No significant differences were found in carotid stiffness parameters (distensibility, MRSD, and PWV), even though these patients had a higher aortic stiffness. Carotid stiffness correlated linearly with age and similar slopes were obtained for BAV patients and controls. No difference in carotid WSS was found between BAV patients and controls.ConclusionOur results clearly show that the carotid stiffness and flow parameters are not altered in case of BAV compared with controls.

“…14 The clinical potential of this approach has been demonstrated in various fields of medicine including breast lesions detection, 18 liver fibrosis staging, 19 and the assessment of arterial stiffness. 20 Due to technical challenges related to image depth, intercostal sector imaging and a continuously moving target, first implementations of cardiac SWI have occurred only recently and studies investigating the use of SWI to quantify myocardial stiffness were initially mainly performed in open-chest animal models. [21][22][23] Improvements in ultrasonography techniques demonstrated lately also the feasibility of this method in in vivo closed-chest animals and humans.…”

Concepts and applications of ultrafast cardiac ultrasound imaging

The concept of ultrafast echocardiographic imaging has been around for decades. However, only recent progress in ultrasound machine hardware and computer technology allowed to apply this concept to echocardiography. High frame rate echocardiography can visualize phenomena that have never been captured before. It enables a wide variety of potential new applications, including shear wave imaging, speckle tracking, ultrafast Doppler imaging, and myocardial perfusion imaging. The principles of these applications and their potential clinical use will be presented in this manuscript.
