Evaluation of concentric left ventricular geometry in humans: evidence for age-related systematic underestimation.
There might be limitations in identifying concentric left ventricular (LV) geometry by ratio of diastolic posterior wall thickness (WT(p)) to cavity radius, defined as relative wall thickness (RWT(p)). This study has been designed to evaluate age effects on RWT(p). WT(p), mean of septal thickness and WT(p) (WT(m)), and cavity radius were cross-sectionally evaluated in 766 1- to 85-year-old, nor...
متن کاملDoes defibrillation threshold increase as left ventricular ejection fraction decreases?
AIMS Advanced cardiac disease, entailing more hypertrophy, fibrosis, scarring, dilatation and conduction delays, poses the question of whether defibrillation thresholds (DFTs) increase as left ventricular ejection fraction (LVEF) decreases. This question has been approached indirectly or insufficiently in previous studies. In this study we add and expand on our previous work, stratifying DFT fo...
متن کاملLeft ventricular ejection fraction calculated from volumes and areas: underestimation by area method.
The ejection fraction is one of the most widely used measurements of left ventricular systolic function. Angiographic measurement of ejection fraction is based on determination of roentgenographic magnification and calculation of end-diastolic and end-systolic volumes, assuming a prolated ellipse. Because it is simple and radiographic magnification may not have been determined, some laboratorie...
متن کاملHigh myocardial 18F-FDG uptake after chemotherapy in the presence of left ventricular dysfunction as well as 3-month later with no left ventricular dysfunction
Diffusely increased glucose metabolic activity in the right and left ventricles using 2-deoxy-2-(F-18) fluoro-D-glucose positron emission tomography/computed tomography (18F-FDGPET/CT) and global left ventricular hypokinesia at echocardiography can be evident in acute myocarditis. But, there has been no case report that the ventricular 18F-FDGuptake remains unchanged even ...
متن کاملa case report of left ventricular wall rupture
cardiac rupture, particularly rupture of the left ventricular wall, has a very high mortality rate. in this occasion, even if injured patients being alive when carried to the hospital, many of them will die due to following possible reasons: severe bleeding, cardiac tamponade, wasting time for routine and usual diagnostic procedures or transferring the injured to other hospital equipped for car...
