Common Coronary Anomalies on MDCT

Coronary artery anomalies are rare, and the incidence is around 1 to 2% in the general population. Majority of the patients are asymptomatic and detected while investigating another clinical issue. A few anomalies may be life-threatening due to the malignant course with potential for ischemia and even sudden death. Multidetector computed tomography (MDCT) has high accuracy in detecting these anomalies because of volume rendering (VR) and multiplanar reconstruction (MPR). ‘High take-off’, origin of the coronary artery from the opposite or noncoronary cusp with anomalous course and coronary artery fistula are three most frequent anomalies. MDCT can be a useful screening tool in the study of coronary anomalies

Coffin-Siris syndrome with the rarest constellation of congenital cardiac defects: A case report with review of literature

We report a case of type-A Coffin-Siris syndrome (CSS) with a unique constellation of congenital heart defects. A 17-year-old Indian boy was referred to our hospital for central cyanosis with features of right heart failure. The cardiac abnormalities included biventricular outflow tract obstruction, small atrial septal defect (ASD), subaortic ventricular septal defect, drainage of left superior venacava to left atrial appendage, and aortic arch anomaly. Patient underwent successful right ventricular infundibular resection, subaortic membrane resection, closure of atrial and ventricular septal defect, rerouting left superior vena cava to left pulmonary artery and aortic valve replacement

Fabrication of the Mesoporous Fe@MnO₂NPs–MCM-41 Nanocomposite: An Efficient Photocatalyst for Rapid Degradation of Phenolic Compounds

Incorporation of nanoparticles in the extraframework of MCM-41 and its effect on the photocatalytic degradation of phenol has been studied. Mesoporous MnO₂ nanoparticles (meso-MnO₂NPs) are incorporated <i>in situ</i> into the extraframework of MCM-41 during its synthesis to obtain mesoporous MnO₂NPs–MCM-41­(MM) materials. Three samples of mesoporous MnO₂NPs–MCM-41 have been prepared with Si/Mn ratios 10, 50, and 90. The sample with Si/Mn ratio 10 shows better textural properties compared to the other two samples. Formation of meso-MnO₂NPs, reversible coordination of Mn ⇄ Si, and formation the Fe-modified MM-10 nanocomposite (mesoporous Fe@MM–10 NC) are the crucial steps involved in the present investigation. The role of CTAB, NH₃, and (NH₄)₂S₂O₈ are the key ingredients for the fabrication of meso-MnO₂NPs and mesoporous Fe@MM–10 NC. The materials are characterized by LXRD, N₂ sorption, and HRTEM to evaluate the mesoporosity, morphology, and textural properties. Mesoporous Fe@MM–10 NC was treated as an efficient photocatalyst for degradation of phenolic compounds, an exemplary move. Nearly 100% degradation of concentrated phenolic compounds (100 mg L^–1) has been achieved within 45 min by mesoporous 5Fe@MM–10 NC. Intraparticle mesoporosity, small particle sizes of the nanocomposite, the formation of a large number of ^•OH radicals, and the generation of high photocurrent are important factors for swift degradation of phenolic compounds by mesoporous 5Fe@MM–10 NC material
