Cerebral and cardiac blood flow are important to the pathophysiology and development of cerebro‐ and cardiovascular diseases. The purpose of this study was to investigate the age dependence of normal ...

Blood vessels are like big-city highways; full of curves, branches, merges, and congestion. Yet for years, lab models ...

Background In intracranial atherosclerotic stenosis (ICAS), low fractional flow (FF ... pressure sensor placed at 1 cm and 2 cm distally to the ICAS lesion. The blood flow was simulated with ...

Objective Fractional flow (FF) reserve has been developed as a gold standard for coronary intervention. Intracranial FF is also a valuable hemodynamic index to assess the severity of narrowing in ...

In patients in whom echocardiography has shown relatively moderate aortic stenosis with or without flow reserve, the literature suggests that surgery should not be performed. However, in individual ...

Four-dimensional flow cardiovascular MRI (4D flow CMR) can more accurately estimate peak aortic valve velocities (V Peak) than traditional transthoracic echocardiography (TTE) in patients with aortic ...

Coronary microvascular function and hemodynamics may play a role in coronary circulation and myocardial remodeling in patients with aortic stenosis (AS). We aimed to evaluate the relationship between ...

“Aortic stenosis is a common yet dangerous heart condition. It happens when the aortic valve, the main outflow valve of the heart, stiffens and narrows. This causes reduced blood flow from the heart ...

Researchers from the University of Sheffield and the University of East Anglia have implemented a cutting-edge 4D flow MRI technology to diagnose aortic stenosis more effectively. This advanced ...

“Aortic stenosis is a common yet dangerous heart condition." “It happens when the aortic valve, the main outflow valve of the heart, stiffens and narrows. This causes reduced blood flow from the heart ...

Aims Four-dimensional flow cardiovascular MRI (4D flow CMR) has emerged as a promising technique for assessing aortic stenosis (AS). This study aimed to evaluate the agreement between 4D flow CMR and ...
