Flow chemistry is the development and study of chemical reactions whereby reactants are combined by pumping fluids, including solutions of reagents, through tubes at known rates. The relative ...

Detection of sclerodegenerative changes of the aortic cusps in an older asymptomatic individual may be associated with normal blood flow velocity. A mild increase in blood flow velocity (1.5-1.7 m ...

Background Cardiogenic shock (CS) induced by severe aortic stenosis (AS) is a life-threatening condition with high mortality. Despite advancements in emergency interventions, the optimal treatment ...

Abstract: Precise measurement of the blood flow velocity in major arteries is important for the assessment of circulation dysfunction but challenging when using a one-dimensional (1D) ultrasound ...

Aortic stenosis (AS) was historically considered a disease of the left side of the heart, with the main pathophysiological impact being predominantly on the left ventricle (LV). However, progressive ...

Vascular rings with left aortic arch (LAA ... the Doppler flow pattern in the descending aorta shows low velocity systolic and diastolic flow. The difference in amplitude of the waveform during ...
