Severe reversible dilated cardiomyopathy associated with a large left ventricular thrombus in a young child with middle aortic syndrome
this article reports a case of a seven-year girl who presented with severe dilated cardiomyopathy (DCM)
associated with a large thrombus in the left ventricle (LV). She had a long segment stenosis of the
lower thoracic descending aorta, possibly due to non-specific aortitis and underwent successful
stent angioplasty. The LV thrombus resolved after heparin without sequelae.peer-reviewe
Scalar Levin-Type Sequence Transformations
Sequence transformations are important tools for the convergence acceleration
of slowly convergent scalar sequences or series and for the summation of
divergent series. Transformations that depend not only on the sequence elements
or partial sums but also on an auxiliary sequence of so-called remainder
estimates are of Levin-type if they are linear in the , and
nonlinear in the . Known Levin-type sequence transformations are
reviewed and put into a common theoretical framework. It is discussed how such
transformations may be constructed by either a model sequence approach or by
iteration of simple transformations. As illustration, two new sequence
transformations are derived. Common properties and results on convergence
acceleration and stability are given. For important special cases, extensions
of the general results are presented. Also, guidelines for the application of
Levin-type sequence transformations are discussed, and a few numerical examples
are given.Comment: 59 pages, LaTeX, invited review for J. Comput. Applied Math.,

Hypoplastic left heart syndrome with coronary-cameral fistulas: Echocardiographic demonstration of coronary artery steal and successful interventional treatment
We report a case of a patient with hypoplastic left heart syndrome with significant coronary-cameral fistulas and exertional symptoms from coronary steal. Symptoms resolved following successful coil occlusion of his left ventricle
