    Ruptured sinus of Valsalva (RSOV) is a rare lesion in a paediatric age group. A right sinus of Valsalva aneurysm usually ruptures into the right ventricle, while aneurysms of non-coronary sinus do so into the right atrium. RSOV usually presents in the third decade of life with congestive heart failure and is more common among Asians with male predominance. It may present as acute cardiogenic shock and sudden death or may remain completely asymptomatic with incidental detection by a murmur. Surgery is indicated as early as possible, once the diagnosis is made as without surgery, most cases will eventually succumb to uncontrollable congestive heart failure. This article reports an 11 year old child with the diagnosis of ruptured sinus of Valsalva.peer-reviewe

    The Plasma Electrolysis Phenomenon in a Two-Compartment Reactor for Chlor-Alkali Production

    Chlor-alkali is one of the most important processes in the chemical industry. It produces chlorine and caustic soda, which become the main feedstock of daily products. The aim of this study is to report the phenomenon of plasma electrolysis and how it can be used in chlor-alkali production for more efficient energy consumption. When the plasma is formed, the current fluctuates and gradually declines. Plasma electrolysis begins with the process of electrolysis itself. Due to Joule heating, gas bubbles are formed and a sheath is made on both electrodes, resulting in the plasma field. Plasma electrolysis can be identified by its radical production. The higher the voltage and concentration, the greater the production of radicals. In 10 minutes or less, the number of OH radicals produced can reach 4 ppm at 400 V and 0.1 M. This amount is relatively small and is caused by other reactions consuming OH radicals to form other radicals such as chlorine. The energy consumption of plasma electrolysis in this study can reach 16 kJ/mmol Cl2 at 0.5 M NaCl solution

    RCC prolapse causing Aortic regurgitation in a restrictive VSD

    The incidence of aortic right coronary cusp (RCC) prolapse in outlet ventricular septal defect (VSD) is reported at 5%- 16%. Detection of RCC prolapse is critical in patients with outlet VSD because this complication may cause permanent aortic regurgitation. Aortic regurgitation occurs due to a poorly supported RCC combined with the venturi effect due to the VSD jet resulting in cusp prolapse. This is an indication for VSD closure even if VSD is small and restrictive.peer-reviewe

    Profile and risk factors for congenital heart defects: A study in a tertiary care hospital

    Introduction: Congenital heart defects (CHDs) are an important cause of mortality and morbidity in children representing a major global health burden. It is thus important to determine their prevalence and spectrum and identify risk factors associated with the development of heart defects. Materials and Methods: A case-control study was carried out in the Department of Pediatrics and Center of Cardiology, Jawaharlal Nehru Medical College, Aligarh Muslim University, Aligarh, Uttar Pradesh, India, from February 2014 to August 2015. All patients referred with complaints or clinical examination suggestive of CHDs were further evaluated with echocardiography. On Echocardiography, patients having CHDs were included as cases and those having a normal echocardiographic study were included as controls. Healthy controls were also included. 400 cases and 400 controls were thus identified; preterms having patent ductus arteriosus and patent foramen ovale and those with acquired heart defects were excluded. Risk factors among cases and controls were further studied. Results: Acyanotic heart defects were 290 (72.50%) of the total heart defects, whereas the contribution of cyanotic heart defects was 110 (27.50%). Out of all CHDs, ventricular septal defect was the most common lesion with contribution of 152 (38%) cases, whereas among the cyanotic heart defects, Tetralogy of Fallot was the most common lesion (18% of total cases). Out of the total 400 cases, 261 were males (65.25%). On univariate analysis, paternal age (odds ratio, OR, 2.01), bad obstetric history (OR, 2.65), antenatal febrile illness (OR, 4.12), and advanced maternal age (OR, 3.28) were found to increase the risk of CHD whereas intake of multivitamin (OR, 3.02) was found to be protective. The risk factors were further analyzed with multivariate logistic regression analysis and all the above factors were found to be significantly associated. Conclusion: We noted that the profile of CHD in our population was similar to the published literature although many were missed during infancy and detected later in life. Several antenatal factors were found to be associated with the incidence of congenital heart disease emphasizing the need to prioritize antenatal care and counseling to pregnant mothers along with good maternal nutrition and folic acid supplementation
