OBJECTIVES The aim of this study was to explore the left ventricular (LV) deformation changes and the potential impact of deformation on outcome in patients with proven light-chain (AL) amyloidosis and LV hypertrophy. BACKGROUND Cardiac involvement in AL amyloidosis patients is associated with poor outcome. Detecting regional cardiac function by advanced(More)
OBJECTIVES Since diastolic abnormalities are typical findings of cardiac amyloidosis (CA), we hypothesized that speckle-tracking-imaging (STI) derived longitudinal early diastolic strain rate (LSRdias) could predict outcome in CA patients with preserved left ventricular ejection fraction (LVEF >50%). BACKGROUND Diastolic abnormalities including altered(More)
Image segmentation is an ubiquitous task in medical image analysis, which is required to estimate morphological or functional properties of given anatomical targets. While automatic processing is highly desirable, image segmentation remains to date a supervised process in daily clinical practice. Indeed, challenging data often requires user interaction to(More)
Cardiovascular disease is the leading cause of death worldwide and for this reason computer-based diagnosis of cardiac diseases is a very important task. In this article, a method for segmentation of aortic outflow velocity profiles from cardiac Doppler ultrasound images is presented. The proposed method is based on the statistical image atlas derived from(More)
When comparing experimental data obtained from different subjects, a standard approach is to display results on an atlas , as a common anatomical substrate. Through time, different methodologies for atlas constructions have been developed. A lot of works on this topic discuss the selection of the " best " atlas, using different criteria. In this article we(More)
