Methods 30 patients (21 male, 9 female; median age 69.5 years) with diagnosis of TTR amyloidosis (wild-type n=13, hereditary n=17) were evaluated by cardiac MRI (CMR; Achieva Intera Philips Medical Systems, Best, The Netherlands), and Technetium-DPD scintigraphy. EDV, ESV, EF and myocardial mass were analyzed on a standard workstation (Philips Viewforum). Longitudinal function was assessed by m...

Background Cardiac Magnetic Resonance (CMR) imaging is increasingly recognized as the gold standard for evaluating left ventricular function (LVF). Measurement of LVF is typically done manually by tracing endocardial and epicardial borders on a stack of short axis (SA) cine images of the heart and is based on the modified Simpson assumption that the left ventricle approximates a spherical shape...

The thermal radiative transfer (TRT) equations form an integro-differential system that describes the propagation and collisional interactions of photons. Computing numerical solutions TRT accurately efficiently is challenging for several reasons, first which defined on a high-dimensional phase space includes independent variables time, space, velocity. In order to reduce dimensionality classic...

conclusions these findings emphasize the potential clinical benefits of therapeutic procedures such as cardiac resynchronization therapy (crt) or apex-sparing volume-reduction surgery in dcm. a better definition of the role and implications of reverse apical torsion in dcm and its importance and effectiveness in making therapeutic decisions like crt implantation requires further studies. case p...

(1) An incised wound semi-circular in shape, 4|inches in length, near the crown of the head, ou tiie left side of the median line; a portion of the skull (left parietal bone at its posterior inferior angle) by 2" having been entirely cut off in a slanting way, and the brain substance protruding through the cavity thus created. (2) Another wound, similar in shape and length to the above, but sit...

The importance of loss in the field solution for left-handed media, and in particular, the impact on what would otherwise be a purely evanescent field, is addressed. Using an equivalent electric current source, field solutions are constructed in semi-infinite and finite thickness left-handed media. In the slab case, field growth and power dissipation metrics with uniform amplitude and uniform p...

While a 74-year-old man with a past history of cerebral infarction was undergoing surface echocardiography due to transient atrial fibrillation, an unstable, pedunculated tumor was detected in the left ventricular outflow tract. As the results of transesophageal echocardiography suggested a left ventricular tumor, semi-emergency surgery was performed. Based on pathological findings, the tumor w...
