title: Use of contrast enhancement for the assessment of left ventricular function.
abstract: Endocardial visualization is essential for accurate interpretation of regional wall thickening abnormalities, which constitute the diagnostic hallmark of coronary artery disease, and for reproducible assessment of left ventricular (LV) ejection fraction. Unfortunately, in many cardiac patients, poor image quality does not allow consistent visualization, let alone automated detection, of the endocardial boundary in all segments throughout the cardiac cycle. Continuing efforts directed towards improving endocardial visualization made by both echocardiographic imaging equipment manufacturers and researchers have recently produced new objective, quantitative approaches for the assessment of global and regional LV function. Although these developments have not been integrated into routine clinical practice, they may have a positive impact on endocardial visualization and, thus, eventually improve the ability to accurately and objectively evaluate LV performance. In this review, we discuss some of the latest developments in the use of contrast for the evaluation of LV function.
