Spatial heterogeneity of intracardiac 4D relative pressure fields during diastole
نویسندگان
چکیده
Background Blood flow within the cardiovascular system is driven by pressure differences, where blood accelerates from higher to lower pressure areas. Invasive methods of pressure measurement, which are commonly applied to assessment of diastolic function, may not capture the heterogeneity of regional intracardiac pressure differences. We utilized pressure fields based on time-resolved 3D CMR data to investigate the timing and distribution of intracardiac pressure gradients in the left heart throughout diastole.

Spatial heterogeneity of four-dimensional relative pressure fields in the human left ventricle.
PURPOSE To assess the spatial heterogeneity of the four-dimensional (4D) relative pressure fields in the healthy human left ventricle (LV) and provide reference data for normal LV relative pressure. METHODS Twelve healthy subjects underwent a cardiac MRI examination where 4D flow and morphological data were acquired. The latter data were segmented and used to define the borders of the LV for ...
متن کاملTransseptal pressure gradient and diastolic ventricular septal motion in patients with mitral stenosis.
Previous studies from our laboratory have shown that the position of the ventricular septum relative to the two ventricles at end-diastole is determined by the instantaneous transseptal pressure gradient (TSG) defined as left ventricular minus simultaneous right ventricular pressure. Since patients with mitral stenosis often have exaggerated leftward (paradoxic) motion of the ventricular septum...
متن کاملIntracardiac hemodynamic forces using 4D flow: a new reproducible method applied to healthy controls, elite athletes and heart failure patients
Background Blood flow in the left ventricle (LV) is closely linked to the function of valves, great vessels and the myocardium. Previous studies have used the Pressure Poisson Equation (PPE) to compute relative pressure fields from 4D flow data. However, the PPE may be numerically sensitive to errors in velocities and delineations. Hemodynamic forces is a quantitative measure similar to relativ...
متن کاملThree-dimensional, time-resolved (4D) relative pressure mapping using magnetic resonance imaging.
We describe here a method for generating relative pressure maps from magnetic resonance velocity data in three spatial and one temporal dimension (4D). The relative pressure map calculated for pulsatile flow in a compliant phantom was shown to be consistent with independent pressure transducer measurements. The feasibility of performing 4D pressure mapping in vivo is also demonstrated.
متن کاملThe aortic closure sound in pure aortic insufficiency.
The second sound in aortic insufficiency has been described as accentuated, normal, or moderately diminished. A study of intracardiac phonocardiograms was performed to evaluate its intensity and to eliminate extracardiac factors. Pressure and intracardiac sound measurements were made in 28 patients undergoing diagnostic cardiac catheterization. Recordings were obtained above the aortic valve an...
