The role of vortex ring formation and pressure drop on dynamics of the left ventricle during diastole

Rheumatoid arthritis (RA) is a systemic autoimmune condition that chronic, inflammatory, and can affect any joint in the body. defined by symmetric inflammation of synovial joints, which eventually lead to erosion cartilage bone. The objective this study was measure CCN3, CRP, I.R, Insulin .F.G, Lipid profiles patients with arthritis. current comprised total 120 participants, who were separated...

The purpose of this study is to elucidate the role, which Wall Shear Stress (WSS) differentiation between diastole and systole plays in coronary atherosclerosis. A finite-element analysis of the 3D, pulsatile, nonNewtonian, heamodynamics of the normal human left main coronary artery bifurcation, based on published data, is performed. The time averaged mean WSS in the entire left coronary artery...

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 d...

taut stream throughout diastole, sometimes actually increasing the diastolic murmur in later diastole. Despite the intensity of the murmur of catheter-induced pulmonic valve rupture in our patient, he appeared to suffer no immediate untoward effects. Similar benign consequences of pulmonic valve regurgitation have been reported by In addition, one of the two other reported patients with cathete...

Diastolic bulging of the interventricular septum (IVS) toward the left ventricle was observed by real-time cross-sectional echocardiography in three patients with primary pulmonary hypertension and one patient with secondary pulmonary hypertension after closure of an atrial septal defect. M-mode echocardiography showed a characteristic abnormal pattern of septal motion in diastole and in systol...
