Assessment of left ventricular function by three-dimensional echocardiography.
Accurate determination of LV volume, ejection fraction and segmental wall
motion abnormalities is important for clinical decision-making and
follow-up assessment. Currently, echocardiography is the most common used
method to obtain this information. Three-dimensional echocardiography has
shown to be an accurate and reproducible method for LV quantitation,
mainly by avoiding the use of geometric assumptions. In this review, we
describe various methods to acquire a 3D-dataset for LV volume and wall
motion analysis, including their advantages and limitations. We provide an
overview of studies comparing LV volume and function measurement by
various gated and real-time methods of acquisition compared to magnetic
resonance imaging. New technical improvements, such as automated
endocardial border detection and contrast enhancement, will make accurate
on-line assessment with little operator interaction possible in the near
future
Ultrasound Imaging Versus Morphopathology in Cardiovascular Diseases: The Heart Failure
This review article summarizes the results of histopathological studies to assess heart failure in humans. Different histopathological features underlying the clinical manifestations of heart failure are reviewed. In addition, the present role of echocardiographic techniques in assessing the failing heart is briefly summarized
