Abstract
Anomalies of the coronary arteries are reported in 1-2% of patients among diagnostic angiogram. Ectopic origin of right coronary artery (RCA) from opposite sinus is one of the most common and they are mainly benign, but at times may be malignant. We report a case of a 69-year-old male who underwent early invasive percutaneous coronary intervention for non-ST-segment elevation myocardial infarction (NSTEMI) where RCA arising from left sinus at the root of left main artery was culprit and various technical challenges were encountered while intervening in form of cannulation to tracking of hardwares. RCA was cannulated with floating wire technique using hockey stick guide catheter and revascularized by deployment of 3.5 × 38 mm Promus Premier Everolimus eluting stent (Boston Scientific, USA). To the best of our knowledge, this is the first ever report of ectopic RCA being revascularized by using hockey stick catheter.

Abstract
The nanometer scale lattice deformation brought about by the dopants in the high temperature superconducting cuprate La_{2-x}Sr_{x}CuO_{4} (x=0.08) was investigated by measuring the associated x-ray diffuse scattering around multiple Bragg peaks. A characteristic diffuse scattering pattern was observed, which can be well described by continuum elastic theory. With the fitted dipole force parameters, the acoustic-type lattice deformation pattern was reconstructed and found to be of similar size to lattice thermal vibration at 7 K. Our results address the long-term concern of dopant introduced local lattice inhomogeneity, and show that the associated nanometer scale lattice deformation is marginal and cannot, alone, be responsible for the patched variation in the spectral gaps observed with scanning tunneling microscopy in the cuprates.

Abstract
A 72-year-old male with diabetes and smoking as coronary risk factors was evaluated for chronic stable angina - Canadian Cardiovascular Society III - despite guideline directed medical treatment which revealed a diffuse, tortuous, calcified narrowing (90% stenosis) in left circumflex (LCx) coronary artery. After predilatation, a 3.0 - 2.5 × 60 mm BioMime Morph stent - long tapering stent (Sirolimus eluting stent, Meril life Sciences, India) - was tracked which failed and dislodged to right deep femoral artery during its pullback. It was successfully retrieved by EN snare: 6 - 10 mm (Merit Medical, USA) by contralateral femoral approach. Lesion was further dilated and successfully stented with another 3.0 - 2.5 × 60 mm BioMime Morph stent at 10 atm pressure showing proper stents expansion with TIMI-3 coronary flow. Our case highlights trackibility issues and importance of adequate lesion preparation before stent deployment in a tortuous and calcified vessel especially with very long stent. To the best of our knowledge, this is the first such case report demonstrating dislodgement and successful retrieval of long, tapered Morph stent.

Abstract
Congenital coronary artery anomalies are rare and usually an incidental finding during coronary angiography. Most of the anomalies are benign in nature; however, some are malignant and may result in sudden cardiac death. A 46-year-old woman with diabetes and hypertension underwent coronary angiography for evaluation of exertional angina, which revealed an unusual trifurcation of a single left coronary artery with an anomalous origin of the right coronary artery from the left anterior descending artery but no significant coronary narrowing. The patient was managed conservatively.

Abstract
IgG4-related kidney disease (IgG4 RKD) is increasingly reported with varied manifestations. The present study was carried out to study the spectrum of IgG4 RKD. All patients with renal manifestation associated with conditions known to be associated with IgG4-related diseases (IgG4 RDs), or renal imaging or histology suggestive of IgG4 RKD were included and evaluated further. Patients with known extrarenal IgG4RD were also screened for renal involvement. Out of 40 patients screened over a period of 15 months, IgG4 RKD was diagnosed in 8. Majority were male (87.5%) with mean age being 56 years. Disease spectrum ranged from normal renal function in one to renal failure requiring dialysis in another two patients. Significant proteinuria was uncommon (12.5%) while hematuria was not seen in any patient. Tubulointerstitial nephritis was seen in all four patients who underwent kidney biopsy. Two patients had associated glomerular lesions in the form of immune complex crescentic glomerulonephritis. The most common imaging abnormality was hypodense renal lesions seen in 2 patients. Elevated IgG4 levels had 87.5% sensitivity and 78.3% specificity for IgG4 RKD and levels did not correlate with disease severity. Of 4 patients treated with steroids, 3 showed improvement in renal function. IgG4 RKD is an uncommon disease even at a referral tertiary care center. Elevated IgG4 levels alone are neither sensitive nor specific for the diagnosis of IgG4 RKD, and a combination of clinical, imaging, serological, and histological features are required for diagnosis.

Abstract
Transcatheter therapy of valvular pulmonary stenosis is one of first catheter interventions facilitating its application in field of structural heart disease and now treatment of choice for significant pulmonary stenosis. Myriads of balloon catheter have been used for this purpose starting from Diamond (Boston Scientific,Natick, MA USA), Marshal (Medi-Tech,Watertown MAUSA), Innoue balloon, Tyshak I and currently Tyshak II. Diameter and length of balloon depend on size of annulus and age group, respectively. Problem with shorter balloon is difficulty in keeping it across the annulus while inflation as it tends to slip distally whereas with longer balloon, potential of tricuspid leak or conduction block as it may impinge on adjacent structures. Potential advantage of Accura balloon over Tyshak balloon lies in its peculiar shape while inflation and variable diameter, making stepwise dilatation possible. Here, we report a case of successful balloon pulmonary valvuloplasty using Accura balloon (Vascular Concept, UK) with little modification of conventional technique.

Abstract
Background Limited data are available regarding safety and feasibility of transcatheter interruption of ruptured sinus of Valsalva aneurysm (RSOVA) using the Cocoon duct occluder (CDO) with immediate and mid-term follow-up result. Methods Transcatheter closure (TCC) was successfully done among eight patients, whereas five cases, not amenable to TCC, were referred for surgical correction among 13 consecutive patients of RSOVA at LPS Institute of Cardiology, Kanpur between January 2010 and March 2015. Results Their mean age was 26.1 ± 6.9 years. Sites of rupture were from right coronary sinus (RCS) to right atrium (RA) in one (12.5%), right ventricle in one (12.5%), and non-coronary sinus to RA in six patients (75%). The defects (9 - 17 mm) were closed by CDO (12/10 - 20/18 mm) with 100% procedural success. During follow-up (9 - 26 months), there was no residual shunt, progression of AR, infective endocarditis or device embolization. Conclusion TCC of RSOVA appears to be a safe and feasible alternative to surgical therapy, with high technical success and excellent mid-term follow-up.

Abstract
We report an x-ray photon correlation spectroscopy method that exploits the recent development of the two-pulse mode at the Linac Coherent Light Source. By using coherent resonant x-ray magnetic scattering, we studied spontaneous fluctuations on nanosecond time scales in thin films of multilayered Fe/Gd that exhibit ordered stripe and Skyrmion lattice phases. The correlation time of the fluctuations was found to differ between the Skyrmion phase and near the stripe-Skyrmion boundary. This technique will enable a significant new area of research on the study of equilibrium fluctuations in condensed matter.

Abstract
Aim:: A comparative study was conducted on crossbred cattle and buffaloes to investigate the effect of feeding high and low roughage total mixed ration (TMR) diets on rumen metabolites and enzymatic profiles. Materials and Methods:: Three rumen-fistulated crossbred cattle and buffalo were randomly assigned as per 3×3 switch over design for 21-days. Three TMR diets consisting of concentrate mixture, wheat straw and green maize fodder in the ratios of (T1) 60:20:20, (T2) 40:30:30, and (T3) 20:40:40, respectively, were fed to the animals ad libitum. Rumen liquor samples were collected at 0, 2, 4, 6, and 8 h post feeding for the estimation of rumen biochemical parameters on 2 consecutive days in each trial. Results:: The lactic acid concentration and pH value were comparable in both species and treatments. Feed intake (99.77±2.51 g/kg body weight), ruminal ammonia nitrogen, and total nitrogen were significantly (p<0.05) higher in buffalo and in treatment group fed with high concentrate diet. Production of total volatile fatty acids (VFAs) was non-significant (p>0.05) among treatments and significantly (p<0.05) greater in crossbred cattle than buffaloes. Molar proportions of individual VFAs propionate (C3), propionate:butyrate (C3:C4), and (acetate+butyrate):propionate ([C2+C4]:C3) ratio in both crossbred cattle and buffalo were not affected by high or low roughage diet, but percentage of acetate and butyrate varied significantly (p<0.05) among treatment groups. Activities of microbial enzymes were comparable among species and different treatment groups. A total number of rumen protozoa were significantly (p<0.05) higher in crossbred cattle than buffaloes along with significantly (p<0.05) higher population in animal fed with high concentrate diet (T1). Conclusion:: Rumen microbial population and fermentation depend on constituents of the treatment diet. However, microbial enzyme activity remains similar among species and different treatments. High concentrate diet increases number of rumen protozoa, and the number is higher in crossbred cattle than buffaloes.

Abstract
Background and aim The purpose of this study was to assess incidence, predictors and outcome of radial artery occlusion (RAO) after transradial catheterization (TRC) based on clinical and Doppler ultrasound study. Methods A total of 1,945 consecutive patients undergoing transradial catheterization for diagnostic evaluation or intervention were included. Radial artery examination was based on palpation and colour Doppler study on the day before, 1 day (D1), 1 month (D30) and 6 months (D180) following the procedure. RAO was defined as absence of pulse on palpation and forward flow on Doppler study. Predictors of RAO were found by logistic regression analysis. Results Baseline demographic and procedural data were recorded. The mean radial arterial diameter was 2.56 ± 0.29 mm. On D1, radial artery Doppler examination revealed RAO in 339 patients (17.4%) but pulse was still palpable in 115 (34%) of them. At D30, these were 221 (11.4%) and 114 (52%), respectively, as no new RAO were noted. Interestingly, 118 (34.8%) patients had spontaneous recanalization of their radial artery as shown by catch-up in patency rate. At D180, these were 99 (5.1%) and 68 (69%), respectively, meaning further new catch-up implying further recanalization. Patients with persistent RAO remained asymptomatic. On multivariate analysis, female sex, diabetes, lower BMI, radial artery diameter ≤2.2 mm and radial artery-to-sheath ratio (AS ratio) < 1 were predictors of RAO. Conclusion TRC for coronary angiography, ad hoc and staged angioplasty can be performed with similar efficacy and safety though RAO occurs more frequently in patients with prior radial artery cannulation and with larger sheath size. Persistent RAO remains asymptomatic.

Abstract
Dual left anterior descending (LAD) artery is a rare coronary anomaly. We present a patient with a rare case of dual LAD, smaller one arising from the left main coronary stem and larger one from right coronary artery who presented with acute anterior wall myocardial infarction with complete heart block (CHB). Temporary pacemaker was implanted and coronary angiogram revealed critical occlusion of proximal LAD which was subsequently revascularized by primary angioplasty using drug-eluting stent (Xience prime, 2.75 × 23 mm) leading to recovery of CHB and restoration to normal rhythm. To the best of our knowledge, this is the first reported case of dual LAD presenting with CHB treated by primary angioplasty reported in the literature.

Abstract
Anomalies of the coronary arteries are reported in 1-2% of patients among diagnostic angiogram. Dual origin of a circumflex from both sinuses is extremely rare among them. We report a case of a patient who underwent primary percutaneous coronary intervention for acute inferior wall myocardial infarction where left coronary injection demonstrated normal obtuse marginal and right coronary injection demonstrated normal right coronary artery (RCA). On further probing, an anomalous left circumflex (LCx) artery was seen arising from RCA ostium which was subsequently cannulated and revascularized by deployment of 2.75 × 26 mm Xience Prime drug-eluting stent (Abott Vascular, USA). Herein, we report for the first time primary percutaneous coronary intervention of twin circumflex and also illustrate that anomalous circumflex can be missed if it arises from RCA ostium and if not probed carefully.
