Right coronary artery after origin from right coronary sinus traverses horizontally to run in right atrioventricular groove till the crux of the heart where it divides into posterior descending artery and posterior left ventricular branch. When the right coronary artery after its origin takes an acute high take off from the ostium and then abruptly descends down making a hairpin loop to run in the right atrioventricular groove, it is known as Shepherd's crook right coronary artery which is extremely rare to encounter in routine clinical practice. This interesting coronary artery deformity has great significance per se so far as the coronary physiology and intervention is concerned. We present a case of Shepherd's crook right coronary artery in the most elderly patient of 84 years of age in world literature and detailed review of this peculiar anatomy. Review literature about Shepherds Crook deformity is yet not there in the literature except some case reports and this review article will be providing the interventional cardiologists a detailed insight into the right coronary ischemia secondary to this interesting anomaly.

Objective: The objective is to evaluate the pattern for use of triple-drug therapy (dual antiplatelet therapy [DAPT] and statin) in the management of patients with postacute coronary syndrome (ACS) and associated risk factors in Indian settings. Materials and Methods: This was a retrospective multi-centric (n = 63), real-world, cross-sectional study which included patients (aged ≥18 years) diagnosed with an ACS, post-ACS patients from 3 months to 3 years, and receiving DAPT and lipid-lowering agents for ACS. Demographics, baseline characteristics, risk factors, medical history, and therapy details were retrieved from medical charts. Descriptive and comparative analysis for qualitative and quantitative variable was performed. Results: A total of 1548 patients with a mean age of 57.4 years were included. Male preponderance was observed across all the age groups. A total of 973 patients were on triple-drug therapy, and the most common triple fixed-dose combination prescribed was rosuvastatin, clopidogrel, and aspirin, among all the groups (age-wise: 76.1%–88.6%; sex-wise: 78.5% and 79.2%; clinical status-wise: 75.7%–81.4%). The majority of patients with non-ST-segment elevation myocardial infarction (43.0%), ST-segment elevation myocardial infarction (42.7%), and unstable angina (40.8%) received triple-drug therapy for >6 to ≤12 months duration. Adverse effect observed in patients receiving triple-drug therapy were skin rash (n = 5), bleeding (n = 2), facial puffing (n = 2), and hematuria (n = 2). A total of 357 patients were undergone switch in DAPT therapy (prasugrel to clopidogrel or ticagrelor to clopidogrel). Conclusion: DAPT and statin were the standard of care in majority of ACS patients. Triple fixed-dose combination therapy of aspirin, clopidogrel, and rosuvastatin was the most preferred choice of physicians, for optimal management post-ACS patient in Indian setting.

Context: Catheter-directed thrombolysis (CDT) is a novel mode of thrombolysis where thrombolytic agents are directed through catheter to a specific area of interest; hence, low-dose thrombolytic agent will be required to produce satisfactory thrombolysis results. This will subsequently decrease the bleeding complications. With this postulation, a study was conducted to compare the outcome of CDT versus systemic thrombolysis (ST) in patients with massive and submassive pulmonary embolism (PE). Methods: The present study prospectively included the cases of massive and submassive (high-risk) PE and randomly distributed 25 patients into two groups each: Group A underwent CDT, whereas Group B underwent ST. The outcomes of both the groups were studied including mortality and bleeding complications, and patients were followed up for 6 months. At the end of the study, data were analyzed, and outcomes of both the groups were compared. Results: Baseline characteristics were similar in both the groups. The success rate was 90.4% in Group A (CDT) and 75% in Group B (ST) among patients with massive PE (P = 0.95). The mortality rate was numerically higher in the ST group (12%) than in the CDT group (8%). Bleeding complications were higher in the ST group (20%) than in the CDT group (8%). Conclusion: CDT was found to be noninferior to ST with respect to primary outcomes of mortality and success rate of thrombolysis. CDT had lower occurrence of bleeding episodes. CDT can be considered viable alternative to ST in patients with high bleeding risk.

Background: The goal of this study is to look at the safety and efficacy of angiotensin receptor-neprilysin inhibitors (ARNI) (valsartan/sacubitril), a combination of angiotensin II receptor blocker and neprilysin inhibitor ARNI, in patients with heart failure with preserved ejection fraction (HFpEF). Materials and Methods: Between June and December 2020, retrospective research was conducted on a study participant of primarily angiographically confirmed computer-aided design patients who underwent complete revascularization. A total of 154 HFpEF patients (87 females and 67 males) were treated with ARNI, which was subsequently titrated up to a maximum tolerable dose and monitored in an outpatient clinic. Fifty-six patients were given ARNI while in the hospital for decompensated heart failure before being discharged. Results: Patients were categorized as the New York Heart Association (NYHA) class III (71.4%) and NYHA class II (28.6%). Diabetes mellitus was identified in 52% of patients, while hypertension was found in 78%. Symptomatic clinical improvement was observed, with a substantial decrease in NYHA class down to NYHA class II (P = 0.018). A considerable decrease in NYHA class resulted in symptomatic clinical improvement as well as the rales and peripheral edema had resolved (P < 0.001). The NT-pro-BNP levels were considerably lowered (P < 0.001). The echocardiographic parameters for diastolic function (E/A, E/E' ratios) improved. In individuals with HFpEF, ARNI resulted in significant clinical benefits. Conclusion: In individuals with HFpEF, sacubitril/valsartan, ARNI resulted in significant clinical benefits. A randomized research is also required to see if it results in beneficial outcomes for a wider sample.

Introduction: This study was planned to compare postoperative hemodynamics, blood loss, platelet count, and coagulation parameters in patients undergoing intracardiac repair for tetralogy of Fallot with and without hemofiltration and, in addition, to determine whether hemofiltration during cardiopulmonary bypass (CPB) reduces cytokines in children undergoing intracardiac repair for tetralogy of Fallot. Methods: Thirty children suffering from tetralogy of Fallot were enrolled in the study and randomly divided into two groups: one group had hemofiltration from beginning of rewarming till weaning off CPB, whereas in the other group, hemofiltration was not used during CPB. In the hemofiltration group, samples were taken for the comparison of tumor necrosis factor-α, interleukin-6 (IL-6), and IL-8 levels, before and after hemofiltration. Platelet count, coagulation parameters, postoperative blood loss, extubation time, hemodynamic parameters were recorded for hemofiltration as well as non-hemofiltration group and analysed. Results: The extubation time in the hemofiltration group was 15.6 h (mean), whereas that in the control group was 28.6 h (mean), and the difference, when compared, was significant between the two groups (P = 0.05). The cumulative postoperative blood loss at 24 h was significantly less in the hemofiltration group compared to the control group, 97.4 ml (80–114 ml) versus 159 ml (100–210 ml), respectively, with P = 0.001. No other statistically significant difference could be appreciated in the parameters analyzed. Conclusion: There was a significant reduction in postoperative blood loss and extubation time in the hemofiltration group. There was no significant reduction in cytokines. No significant difference was observed in requirement of inotropic agents, hemodynamic status, and intensive care unit stay between the two groups. Small sample size and shorter ultrafiltration time during rewarming phase were limitations of the study.

We report a case of primary angioplasty of right coronary artery (RCA) through right radial artery access in a patient with aberrant right subclavian artery (arteria lusoria) and anomalous origin of RCA. Major challenges in such cases are difficulty in hooking coronary ostia and getting enough support from the guide catheters. However, another challenge confronted in this patient was the anomalous origin of RCA from the left sinus. Herein, we discuss key aspects of management in this scenario. Arteria lusoria with anomalous RCA can be confronted during the transradial intervention. Use of an appropriate guide catheter to facilitate the procedure in this scenario can help interventionists to manage such a situation, and this can be a useful alternative in those patients with unfavorable transfemoral access along with this rare anomaly.

Introduction: Higher fasting blood glucose level plus raised glycated hemoglobin (HbA1c) levels is one of the major risk factors for cardiovascular (CV) events in nondiabetic population. HbA1c levels have low intra-individual variability especially in nondiabetic patients. Studies have shown that coronary artery disease (CAD) and HbA1c are predictors of CV mortality. In this study, we have evaluated the association between HbA1c and severity of CAD in nondiabetic patients. Materials and Methods: This is a hospital-based observational study done on 300 patients in Department of Medicine and Department of Cardiology, Mahatma Gandhi Medical College and Hospital, Jaipur. Prior approval was taken before the start of study from the Institute Ethics Committee. Gensini score was used to estimate the CAD severity. This score is based on the sum of scores for all 3 coronary arteries to assess the entire extent of CAD. Data were analyzed and appropriate statistical tests were used. P < 0.05 were considered statistically significant. Results: This study showed that the majority of cases (59.33%) were seen in 51–70 years of age group. The maximum number of patients (66.66%) had 5.6–6.5 HbA1c level and 29.36 ± 19.50 Gensini score in our study. Mean Gensini score showed a linear relationship with HbA1c. Conclusion: HbA1c level has a prognostic value for predicting the severity of CAD among nondiabetic patients and can act as a useful marker in risk stratification of nondiabetic patients presenting with acute coronary syndrome and indicated for angiographic evaluation.
