The art and science of predicting postrevascularization improvement in left ventricular (LV) function in patients with severely depressed LV function.
Left ventricular (LV) dysfunction is a well-established and powerful predictor of adverse outcomes (1). Indeed, the occurrence of severe LV systolic dysfunction (i.e., LV ejection fraction [LVEF] 35%), especially in the setting of clinical heart failure (HF), is associated with very poor survival if treated with medical therapy alone (2). In selected high-risk patients with severe LV dysfunctio...
متن کاملReduced Left Ventricular Torsion Early After Myocardial Infarction is Related to Left Ventricular Remodeling Running title : LV torsion in AMI
Background-Left ventricular (LV) torsion is emerging as a sensitive parameter of LV systolic myocardial performance. Aim of the present study was to explore the effects of acute myocardial infarction (AMI) on LV torsion, and to determine the value of LV torsion early after AMI in predicting LV remodeling at 6-month follow-up. Methods and Results-A total of 120 patients with first ST-elevation A...
متن کاملA systematic evaluation of left ventricular (LV) models for estimating LV volumes in children using cardiac cine (MRI)
Results Commonly used biplane[1] and triplane[1] ellipsoid models have significant mean percentage error (at least 9%) for EDV/ESV/EF (Table 1), and triplane model was more reproducible than bi-plane model. A linear-weighted model of biplane and parabola substantially diminishes percentage error for EDV, ESV and EF to 0.3±6.0%, 0.5±10.7% and 0.0±6.4% (aEDV = 0.4, bEDV=0.7; aESV = 0.9, bESV=0.2)...
متن کاملLeft ventricular torsional dynamics post exercise for LV diastolic function assessment
AIMS 2D speckle tracking echocardiography allows for assessment of left ventricular (LV) torsional deformation as a composite function of the radial, longitudinal and circumferential fibres. We test the hypothesis that post-exercise LV torsional dynamics are more sensitive markers for myocardial dysfunction than resting measures, and better predictors for exercise capacity compared to post-exer...
متن کامل3D Strain helps relating LV function to LV and structure in athletes
INTRODUCTION The evaluation of cardiac contraction could benefit from a connection with the underlying helical structure of cardiac fibers in athletes either completely healthy or with minor common cardiopathies like Bicuspid Aortic Valve (BAV). This study aims to exploit the potential role of 3D strain to improve the physiological understanding of LV function and modification due to physical a...
