Coumadin ridge: An incidental finding of a left atrial pseudotumor on transthoracic echocardiography

World Journal of Clinical Cases 2015年第9期3卷 831-834页

作者： aadil mubeen lodhi Tin Nguyen Christopher Bianco Assad Movahed Department of Cardiovascular Sciences East Carolina UniversityBrody School of MedicineEast Carolina Heart Institute

Coumadin ridge is a normal anatomic variant that is occasionally found in the left atrium. It can present as a linear or nodular mass which can undulate with cardiac motion and if particularly prominent, can easily be mistaken for a tumor or thrombus. Careful evaluation and consideration of the common variants discussed in this review can help limit misdiagnosis, as well as unnecessary workup and treatment. We present a case of coumadin ridge that was found on a patient using two-dimensional transthoracic echocardiography.

Bandgap tuning using rare earth metals as dopants in ferrite-based photocatalytic materials has received a lot of interest because the Fermi 4f energy of these metals generates a sub-energy state in the bandgap generated by the overlapping of Fe-3d and O-2p ***,dysprosium-doped cobalt-nickel mixed ferrite(D-CNFO)and its graphene-reinforced composite(D-CNFO@G)were prepared and an ideal photocatalyst material for azo dye mineralization was proposed.A cost-effective combination of wetchemical and ultrasonication methods was used to prepare the doped and composite *** characterization methodologies were used to scrutinize the optical,compositional,structural,morphological,and photocatalytic characteristics of as-prepared *** X-ray diffraction analysis identified the spinel phase's(cubic)structure,while the electronic spectroscopy examination confirmed the prepared samples'rod-like *** UV/visible absorbance spectrum shows the higher light harvesting behavior of the D-CNFO@G in the visible *** mineralization performance of the DCNFO and D-CNFO@G composites was analyzed using Congo-red(an anionic dye),a well-known azo *** D-CNFO@G sample removes Congo-red dye at a rate almost 2.4%faster than the D-CNFO *** experiment involving trapping free radicals indicates that hydroxyl radical play s a crucial role in dye *** the D-CNFO@G catalyst is magnetic and can be isolated easily from the photocatalytic system,it shows an awkward cycle activity of more than 96%after five mineralization *** asprepared D-CNFO@G composite is proved as an excellent option for azo dye mineralization because of the combined impacts of rare earth doping,graphene reinforcement and nanotechnology.

Atrium of stone:A case of confined left atrial calcification without hemodynamic compromise

引用

World Journal of Clinical Cases 2014年第5期2卷 142-145页

作者： Christopher Jones aadil mubeen lodhi Long Bao Cao Arjun Kumar Chagarlamudi Assad Movahed Department of Cardiovascular Sciences East Carolina Heart InstituteBrody School of MedicineEast Carolina UniversityGreenvilleNC 27858United States

Dystrophic cardiac calcification is often associated with conditions causing systemic inflammation and when present,is usually extensive,often encompassing multiple cardiac chambers and *** present an unusual case of dystrophic left atrial calcification in the setting of end stage renal disease on hemodialysis diagnosed by echocardiography and computed *** calcium deposition is confined within the walls of the left atrium with no involvement of the mitral valve,and no hemodynamic effects.
