INTRODUCTION In spite of significant recent advances in imaging modalities for studying cardiac hemodynamics, present day in vivo measurement techniques can only resolve large scale blood flow features. Understanding flow patterns in the heart at physiological conditions and scales sufficiently fine for establishing quantitatively links between disease and patientspecific hemodynamics continues...

Bicuspid aortic valve (BAV) can be both sporadic and hereditary, is phenotypically variable, and genetically heterogeneous. The clinical presentation of BAV is diverse and commonly associated with a high prevalence of valvular dysfunction producing altered hemodynamics and aortic abnormalities (e.g., aneurysm and dissection). The thoracic aortic aneurysm (TAA) in BAV frequently involves the pro...

Background-—Little is known about the hemodynamic response to exercise in heart failure patients at various ages before and after heart transplantation (HT). This information is important because postoperative hemodynamics may be a predictor of survival. To investigate the hemodynamic response to HT and exercise, we grouped our patients based on preoperative age and examined their hemodynamics ...

or more implants providing collaterals to coronary arteries, and 10 had no evidence of collaterals from the implant. Only two patients, both with functioning implants, showed a return to normal of left ventricular end-diastolic pressure at rest and during exercise. There was no correlation between clinical improvement and hemodynamics at the time of the postoperative study. It is concluded that...

Background 4D flow CMR analysis of main pulmonary artery (MPA) flow in pulmonary arterial hypertension (PAH) has demonstrated vortical formations whose existence time correlates with mean pulmonary arterial pressure (MPAP). Vorticity can quantitate the rotation of these vortices and may represent a novel way to assess pulmonary arterial hemodynamics. We aimed to determine if MPA vorticity corre...

INTRODUCTION An aneurysm is a vascular disease characterized by local ballooning of an arterial wall. The etiology of aneurysm formation is thought to be due to long-term remodeling of blood vessel wall in response to hemodynamics [1]. Changes in vessel geometry and mechanical properties of blood vessel wall induce alteration in the pattern of hemodynamics which then provides new mechanical sti...

The formation of urine is a process that begins with glomerular filtration and is greatly influenced by changes in renal hemodynamics. Selective filtration of the blood is possible because of the unique characteristics of the glomerulus and renal circulation. Many factors interact to maintain a consistent blood flow allowing filtration and urine formation to continue despite systemic changes in...

Aggressive large volume resuscitation is obligatory to achieve necessary tissue oxygenation. An adequate venous preload normalizes global hemodynamics and avoids multiorgan failure (MOF) and death in patients with multiple injuries. Large volume resuscitation is associated with complications in minimally monitored patients. A properly guided resuscitation procedure will finally prevent MOF and ...
