I welcome to all our readers of Heart India on the publication of second issue of Heart India and would like to thank everybody on overwhelming response to scientific community at the publication of first issue of Heart India.
The contrast induced acute kidney injury (CIAKI) or more commonly known as contrast induced nephropathy (CIN) is a well-known cause of acute renal failure in a hospital setting. CIAKI is defined as an abrupt (within 48 h) reduction in kidney function, evidenced by an increase in the serum creatinine (Cr) concentration of at least 0.3 mg/dL or at least 50% from baseline or a reduction in urine output (documented oliguria of <0.5 mL/kg/h for >6 h).  In first review article Sudarshan et al. reviewed contrast induced nephropathy in very detail but concise way.
Second article is an original research article by Dr Jyoti about variation in coronary artery anatomy based on cadaveric heart autopsy. Variations of coronary arteries can cause important clinical manifestation, including sudden death of the individual. In 100% of cases, the right coronary artery (RCA) and main left coronary artery (LCA) were found to arise from anterior aortic sinus and left posterior aortic sinus, respectively. In 8% of cases, the conus were found to have independent origin from the anterior aortic sinus. The RCA was found to be dominant in 90% of cases. In 10% of cases, the circumflex coronary artery was found to be dominant. In 10% of cases, LCA trifurcated, into ramus intermedius branch along with left anterior descending coronary artery and left circumflex artery. Also, 43.3% of LAD showed myocardial bridging predominantly in the middle 1/3 rd segment, and 6.7% of cases of RCA showed myocardial looping. In this study incidence of myocardial bridge is quiet high in comparison to angiographic studies, this is probably because of deference in definitions used.
Again third article is an original research article by Pakkala et al. short term effects smokeless tobacco on cardio-respiratory fitness. Smokeless tobacco has been advocated as a substitute for cigarette smoking. On the contrary, the use of smokeless tobacco is fraught with health risk and needs to be discouraged. Although previous reports have described long-term harmful effects of smokeless tobacco on various body parameters, little is known about short-term effects of smokeless tobacco on cardio-respiratory parameters. Very few studies have been undertaken on the effect of short-term use of smokeless tobacco in India on cardio-respiratory parameters of youngsters. The present study has been undertaken to study the effect of smokeless tobacco on cardio-respiratory fitness tests in young healthy tobacco chewers compared to age- and sex-matched nontobacco chewing healthy controls. Various cardio-respiratory parameters like resting HR, delta HR, MVV, VE max, VO 2 max were studied by using treadmill exercise testing and computerized spirometry. In this study no statistically significant difference was found in any parameter studied that can be attributed to the residual effect of short-term use of smokeless tobacco.
Three case reports are being published in this issue. Transvenous pacing is the most common practiced way of permanent pace maker implantation. Complication can occur during or after the procedure and they are easily diagnosed by electrocardiogram (ECG), fluoroscopy, and echocardiography. Usually, a left bundle branch block (LBBB) pattern in surface ECG recording is observed after a right ventricular (RV) endocardial pacing. The presence of a right bundle branch block (RBBB) pattern raises the suspicion of lead perforation, which necessitates further intervention. However, it can be a normal finding in RV apical pacing. In first case report Ranjith, et al. have reported a case of a RBBB pattern in ECG after RV endocardial permanent pace maker implantation, suggesting a complication.
Angioplasty of anomalous coronary arteries can be technically challenging because of the difficulty in selectively cannulating the aberrant vessel. Dr Nagori has published her experience of angioplasty of an anomalous right coronary artery from left aortic sinus with the use of 6-Fr amplatz left 1 (AL-1) guiding catheter in second case report published in this issue.
In third case report Kinsara et al. have reported a rare complication post-bioprosthetic aortic valve replacement. A middle age man presented with the clinical features of pyrexia of unknown etiology and found out that he had endovascular infection, with septic emboli to the spleen. Authors have presented two interesting images as a quiz and discuss in brief the clinical data of the infected pseudo aneurysm of the aortic root and ascending aorta.
