Instanteous Pressure Distribution along the Human Aorta.
• The ejection of blood into the root of the aorta by the heart produces pressure changes which are transmitted peripherally through the vascular bed. The propagation of these pressure waves has been a topic of interest and conjecture for a number of years because of its importance in the study of the physical properties and energetics of the vascular bed. As a result many data have accumulated...

متن کاملArterial Wall Stiffness Variations Along the Canine Aorta using Pulse Wave Imaging with Validation in vitro
Introduction: The aortic stiffness has been proposed as an independent indicator of cardiovascular disease. Existing methods to estimate the aortic stiffness are either invasive, e.g. catheterization, or yield global (inaccurate) measurements, e.g., applanation tonometry. Pulse wave imaging (PWI) is an ultrasound-based method aiming at noninvasive and regional estimation of pulse wave velocity ...
متن کاملRegional wave travel and reflections along the human aorta: a study with six simultaneous micromanometric pressures.
The human aorta and its terminal branches were investigated in normal subjects during elective cardiac catheterization to evaluate regional wave travel and arterial wave reflections. A specially designed catheter with six micromanometers equally spaced at 10 cm intervals was positioned with the tip sensor in the distal external iliac artery and the proximal sensor in the aortic arch. Simultaneo...
متن کاملChanges in Arterial Stiffness and Wave Reflection With Advancing Age in Healthy Men and Women
With advancing age, arterial stiffness and wave reflections increase and elevate systolic and pulse pressures. An elevated central pulse pressure is generally ascribed to increased wave reflection and portends an unfavorable prognosis. Using arterial tonometry, we evaluated central (carotid-femoral) and peripheral (carotid-brachial) pulse wave velocity, amplitudes of forward and reflected press...
