MRI of left ventricular function
Journal of Nuclear Cardiology, 2007Cardiac magnetic resonance imaging (CMR) is widely recognized as the most accurate noninvasive imaging modality for the assessment of left ventricular (LV) function. By use of state-of-the-art magnetic resonance imaging (MRI) scanners, electrocardiography (ECG)-gated cine images depicting LV function with high contrast and excellent spatial and ...

Assessment of Left-Ventricular Function
The Thoracic and Cardiovascular Surgeon, 1998There are three distinct phases of the cardiac cycle (contraction, active relaxation, and passive relaxation) which should be examined in order to perform a thorough assessment of global left-ventricular function. Accurate measurements of left-ventricular pressure and volume are necessary to assess these phases of the cardiac cycle.

Left ventricular diastolic function
Critical Care Medicine, 2007Cardiovascular morbidity and mortality resulting from congestive heart failure are major concerns for the critical care physician. Although heart failure is commonly associated with impaired systolic function, in up to one half of cases, heart failure occurs exclusively on the basis of an impairment of diastolic function.

Global left ventricular (LV) function is an important prognostic parameter and is useful for therapeutic decision-making. Since its introduction, twodimensional (2D) echocardiography has played an important role in the quantitation of LV function. However, the limitations of 2D echocardiography for the accurate determination of cardiac volumes and ...

TEE is widely used for intraoperative monitoring of global and regional left ventricular function during cardiac surgery. However, caution is necessary in assessing changes in left ventricular function before and after cardiopulmonary bypass because of the unequal loading conditions and the interference of catecholamine administration.

Many of the substitute endpoints used in clinical research on heart disease are parameters obtained using imaging techniques. The most frequently used endpoint is left ventricular ejection fraction (LVEF). At rest and at peak aerobic exercise, left ventricular contractility measurements can be obtained in a clinical setting by noninvasive methods [1 ...

Estimation of Left Ventricular Function in Patients With a Left Ventricular Assist Device
ASAIO Journal, 1995Patients with profound left ventricular (LV) dysfunction supported by a left ventricular assist device (LVAD) may have recovery of LV function, but current methods for assessing this are difficult or not readily available. A new method to estimate LV performance was tested in 6 patients on LVAD (age, 47 +/- 12 years).

Left Ventricular Function in Patients with Centrifugal Left Ventricular Assist Device
ASAIO Transactions, 1989We used blood pool radionuclide angiography to study the left ventricular (LV) ejection fraction (EF) in 17 patients with a centrifugal assist device (AD) placed because of severe postoperative LV dysfunction. During maximal LVAD flow, the 12 patients who could be weaned had a higher LV-EF than the 5 who could not be weaned (18 +/- 12% vs. 9 +/- 2%, p =

Improved Left Ventricular Function After Chronic Left Ventricular Unloading
The Annals of Thoracic Surgery, 1996This study assessed the effect of prolonged left ventricular unloading on native ventricular function.We reviewed data from 31 patients (30 men, 1 woman) supported more than 30 days (mean, 137 days; range, 31 to 505 days) with the HeartMate left ventricular assist system.

Left Ventricular Function and Regression of Left Ventricular Hypertrophy in Essential Hypertension
American Journal of Hypertension, 1993Although left ventricular hypertrophy (LVH) is an adaptive response to the increased load imposed on the heart in patients with hypertension, it ultimately is itself a major risk factor for cardiovascular disease. The influence of LVH on left ventricular function and on the coronary circulation, and the occurrence of serious ventricular arrhythmias are
