Left ventricular vortex formation is unaffected by diastolic impairment.
Normal left ventricular (LV) filling occurs rapidly early in diastole caused by a progressive pressure gradient within the ventricle and with a low left atrial pressure. This normal diastolic function is altered in patients with heart failure. Such impairment of diastolic filling is manifested as an abrupt deceleration of the early filling wave velocity. Although variations within the early fil...
متن کاملThree dimensional right ventricular diastolic vortex rings: characterization and comparison with left ventricular diastolic vortex rings from 4D flow MRI
Background Efficient right ventricular (RV) pumping function requires optimal blood flow dynamics. In the left ventricle (LV), diastolic vortex ring formation distal to the mitral valve (MV) has been reported to be an important mechanism for such blood flow optimization. Earlier work based on computational fluid dynamics (CFD) simulations using simplified RV geometry modeling have reported vort...
متن کاملVortex Ring Formation in Diastolic Dysfunction: Phase Contrast MRI of Left Ventricular Filling
Introduction The formation of vortices during left ventricular (LV) filling (Fig. 1) has been noted in several investigations using phase contrast (PC) MRI [1,2], but the effect of diastolic dysfunction (DD) on vortex formation has not been investigated. We hypothesize that impaired relaxation (IR) and increased stiffness of the LV wall in DD, will substantially alter the kinetics of the vortic...
متن کاملLeft Ventricular Diastolic Performance
We used first-pass radionuclide angiocardiography to assess filling fraction during the first third of diastole, peak filling rate and peak filling rate during the first third of diastole as indexes of left ventricular diastolic performance at rest and after upright bicycle exercise in 32 normal patients and 68 patients with coronary artery disease. The mean filling fraction was unchanged from ...
متن کاملechocardiographic assessment of inappropriate left ventricular mass and left ventricular hypertrophy in patients with diastolic dysfunction
background: early diagnosis of left ventricular mass (lvm) inappropriateness and left ventricular hypertrophy (lvh) can result in preventing diastolic left ventricular dysfunction and its related morbidity and mortality. this study was performed to determine if diastolic dysfunction is associated with lvh and inappropriate lvm. methods: one hundred and twenty five uncomplicated hypertensi...
