Coarctation of the aorta is one of the five main congenital cardiovascular failures, accounting for 6–8 percent of these failures. This research aimed to simulate the blood flow of a seventeen-year-old male teen with a mild coarctation at one-third of his aorta's descending branch. The simulation was performed by extracting the domain and the input pulsatile velocity signal as the boundary cond...

Pulse wave analysis (PWA) allows estimation of cardiac output (CO) based on continuous the arterial blood pressure (AP) waveform. We describe physiology AP waveform, basic principles PWA algorithms for CO estimation, and technologies available clinical practice. The waveform is a complex physiological signal that determined by interplay left ventricular stroke volume, systemic vascular resistan...

BACKGROUND Alterations in the elastic behavior of arteries is an early sign of vascular damage in atherogenesis and may be promoted by oxidative stress (OxS). However, studies designed for simultaneous assessment of arterial elasticity and OxS status in patients with peripheral arterial disease (PAD) are absent. The purpose of this study was to assess large (C1) and small artery elasticity (C2)...

Poor fidelity invasive arterial blood pressure (IABP) traces are a frequent practical problem. It is common practice to describe any such trace as being 'damped'; the resonance behaviour of IABP measurement systems having been extensively described in the literature. However, as poor quality arterial blood pressure signals are seen even with optimal pressure transduction circuits, this cannot b...

Techniques for Studying Arterial Elastic Properties To the Editor: I applaud the effort of Rietzchel and colleagues1 to compare two techniques in wide use for studying arterial elastic properties. This is a study long in need of performance because of the controversial claims in the literature relating to the theory of systolic and diastolic waveform analysis. As we had anticipated and predicte...
