Cleft anterior mitral leaflet with supravalvular aortic stenosis a rare association

A 20 year old female was referred to us for evaluation of effort dyspnoea of NYHA class II with feeble left common carotid, left brachial and left radial artery as compared to other sides. Detail evaluation with two dimensional (2D) transthoracic echocardiographic, 2D transesophageal echocardiography and multidetector computed tomography (MDCT) delineated Cleft AML and diffuse type of supravalvular aortic stenosis. To the best of our knowledge, no such case have been described in the literature where these anomalies co-existed in the same patient.

Symptomatic complete heart block leading to a diagnosis of Kearns–Sayre syndrome

Kearns-Sayre syndrome (KSS) is a rare syndrome characterized by the triad of progressive external ophthalmoplegia, pigmentary retinopathy and cardiac conduction system disturbances; it is a mitochondrial encephalomyopathy with which usually presents before the patient reaches the age of 20. Here we present a case report of a patient with KSS who presented with symptomatic complete heart block.

Diabetes and myocardial infarction: revisiting the conundrum!

Establishment of prompt reperfusion of infarct related artery remains the goal in STEMI management. ST segment resolution is rapid and inexpensive tool to assess efficacy of reperfusion therapy in STEMI at bedside.7 Various studies have also documented the poor prognosis associated with non resolution of ST segment following thrombolysis.8,9 Thrombolytic therapy fails to achieve effective reperfusion in diabetic subset even in a setting of early presentation.10

Landmark Trials in Cardiology in 2017—Celebrating 40 Years of Angioplasty

Abstract Cardiovascular (CV) diseases continue to be the leading cause of morbidity and mortality worldwide. Significant progress has been made in the management of coronary artery disease (CAD) and acute coronary syndrome (ACS) over the past 3 decades. The year 2017 marks 40th anniversary of the first coronary angioplasty performed by Andreas Gruentzig in the year 1977. Evidence‐based medicine and research has been the key driving force of these positive outcomes. The year 2017 witnessed presentation of several landmark studies at major meetings and many of them getting published in literature simultaneously. These trials evaluated wide range of issues from novel percutaneous coronary intervention (PCI) strategies to newer drugs to innovative devices in management of CAD. We selectively discuss a few major landmark studies that have the potential to alter our daily practice in 2018.

Correlation between carotid ultrasonography findings and SYNTAX score in South Asian patients with coronary artery disease: A single-center study

Objective: The objective of the study was to examine the correlation between the carotid ultrasound findings (i.e., carotid intima-media thickness [IMT] and plaque score) and complexity of coronary artery disease (angiographic SYNTAX score) in Indian patients with stable ischemic heart disease. Materials and Methods: This was a hospital-based, prospective, consecutive comparative case series. The study population comprised 117 Indian patients with stable ischemic heart disease, who underwent carotid ultrasonography for the estimation of mean carotid IMT and plaque score and coronary angiography for the estimation of SYNTAX score. Groups comprising patients with low SYNTAX score (0–22; n = 88) and patients with intermediate (23–32) and high (≥33) SYNTAX score (n = 29) were compared for various demographic factors and carotid ultrasound findings. Results: Patients with intermediate or high SYNTAX score had significantly higher prevalence of diabetes (51.7% vs. 15.9%), hypertension (89.7% vs. 30.7%), and hypercholesterolemia (100% vs. 31.8%) as compared to patients with low SYNTAX score (P < 0.001). Further, the mean IMT and plaque scores increased with increasing SYNTAX score. Patients with intermediate and high SYNTAX score had significantly higher mean IMT (1.1 ± 0.1 vs. 0.9 ± 0.1 mm) and plaques score (6.6 ± 1.2 vs. 1.9 ± 1.9 mm) as compared to patients with low SYNTAX score. Significant correlation between SYNTAX score and mean IMT (r = 0.73; P < 0.01) and plaque score (r = 0.68; P < 0.01) was observed. Conclusions: Carotid ultrasound findings showed a significant correlation with the degree of complexity of coronary artery lesions.

Comparison of left internal mammary harvesting techniques for coronary artery bypass grafting: A prospective study

Introduction: Left internal mammary artery (LIMA) is the most common arterial conduit used for patients undergoing coronary artery bypass grafting (CABG) surgery. Maintaining pleural integrity during harvesting has been documented to have better patient outcomes. Hence, we evaluated postoperative outcomes using two different LIMA harvesting techniques, one with intact pleura and other with pleura opened. Methods: In this prospective study, we recruited a total of 110 patients undergoing CABG. Based on the pleural being intact or opened, the patients were divided in two groups. In Group 1, LIMA was harvested with pleura intact (extra-pleural approach) while in Group 2, LIMA was harvested with pleura being opened (intrapleural / pleurotomy). The primary objective was to evaluate the impact on various post-operative parameters like total ventilatory time, mediastinal drainage, need for Blood transfusions, post operative deterioration of lung function , post operative pain scores and duration hospital stay. Results: Out of 110 patients undergoing CABG, LIMA was harvested by extra-pleural approach in sixty-six while in the rest forty-four pleurotomy was needed. The baseline demographic attributes of patients were similar in both groups. The post operative parameters such as ventilatory time, blood loss, need for blood transfusions, and prolonged hospital stay were found to be significantly higher in the group with intrapleural LIMA harvest technique (P <0.05). Pulmonary complications like pleural effusion, atelectasis were more frequent with in the intrapleural harvest as compared to extra-pleural harvest technique.(P <0.001). Post operative pain scores as evaluated by NRS scale were also significantly higher after intrapleural harvest (P <0.001). Conclusions: Harvesting of LIMA for CABG extrapleurally has significant post-operative benefits and faster recovery compared to pleurotomy and intraplueral approach.

A comparative study of tirofiban plus enoxaparin versus enoxaparin alone along with dual antiplatelet blockade in the management of patients with non-ST elevation acute coronary syndrome

Introduction: Antithrombotic therapy in patients with non-ST elevation acute coronary syndrome (NSTE-ACS) includes dual antiplatelet therapy (DAPT) along with enoxaparin. However, resistance to antiplatelet action of aspirin and clopidogrel is well known and is about 27% (0-57%) and 30%, respectively. Hence the use of GPIIb/IIIa inhibitor appears to be a reasonable option as they act on the final common pathway of platelet aggregation. Though frequently used in patients undergoing percutaneous intervention (PC1), their use in patients not undergoing such procedure is not popular despite evidence in literature. Materials and Methods: This study was done on 44 patients of NSTE-ACS managed conservatively. The patients were randomized in a 1:1 fashion in two groups. The patients in group 1 received tirofiban(0.4μg/kg/min i.v for 30 min followed by 0.1μg/kg/min for 48 hours) in addition to aspirin (325 mg stat followed by 75 mg P.O. daily), clopidogrel (300 mg stat followed by 75 mg P.O. daily) and enoxaparin (1 mg/kg S.C bid for 5 days). The group 2 patients received DAPT and enoxaparin only, in similar doses. Both the groups received antianginal therapy as appropriate and statins. Results: The study showed the benefits of adding tirofiban to enoxaparin and DAPT irrespective of age, sex, presence or absence of diabetes and dyslipidemia, ECG changes, troponin positivity and TIMI score in patients with NSTE-ACS. There was a significant reduction {Risk reduction (RR) of 45.4% P <0.01} in composite of primary end points refractory ischemia myocardial infarction (MI) and death with Tirofiban. No major or minor bleeding episodes were seen in any patients. Conclusion: Thus, we conclude that tirofiban in addition to DAPT and enoxaparin reduces the risk of refractory ischemia, MI and death in patients with NSTE-ACS without any additional risk of major or minor bleeding. Therefore, we advocate this regimen in patients with NSTE-ACS managed conservatively. Large randomized study is needed to recommend this regimen.

Evaluation of short-term outcomes of impaired creatinine clearance in patients with acute coronary syndromes: A prospective cohort study at tertiary care center

Background: Chronic kidney disease is commonly seen in patients presenting with acute coronary syndrome (ACS), and it has been shown to have poor outcomes. We evaluated the prevalence of impaired creatinine clearance and its impact on short-term clinical outcomes in patients admitted with ACS without prior documented chronic renal disease. Materials and Methods: The present study was an observational, prospective cohort study conducted at a tertiary care center in North India. In patients admitted with a diagnosis of ACS, glomerular filtration rate was estimated (eGFR) by the Modification of Diet in Renal Disease Study Equation. Patients with eGFR <90 mL/min were taken as study group and those with values >90 mL/min comprised control group. The study group was further categorized into three subgroups on the basis of eGFR (<30 mL/min; 30–59 mL/min; 60–89 ml/min). The primary outcomes compared between study and control group were major adverse cardiac event (MACE) (composite of death, reinfarction, congestive heart failure, cardiogenic shock, and arrhythmia). The secondary outcome measures were individual components of primary outcome. Results: Among the 200 enrolled patients with ACS, the prevalence of impaired creatinine clearance was 29.5%. The study cohort had higher rates of MACE (28.8 vs. 9.2%, P ≤≤ 0.0001), in-hospital mortality (13.6 vs. 3.5%, P = 0.009), and overall mortality (15.3 vs. 5.1%, P = 0.014) as compared to control group. However, the 30-day mortality was not significantly different. The MACE in the study subgroups was higher in eGFR 30–60 mL/min (odds ratio [OR] 3.97) subgroup followed by eGFR <30 mL/min (OR 3.04) and eGFR 60–90 mL/min (OR 1.38). Using eGFR <90 mL/min as cutoff (as compared to serum creatinine [SCr] >1.5 mg/dl) enhances the ability to predict death by 33% and MACE events by 143%. The OR for predicting death with various cutoff of eGFR was as follows: eGFR <30 ml/min – 3.61, eGFR: 30–60 ml/min – 4.2 and eGFR: 60–90 ml/min – 0.5. Conclusion: Almost one-third of the patients presenting with ACS have impaired creatinine clearance. Patients with impaired creatinine clearance have worse outcome in hospital vis-a-vis their contemporary groups with normal eGFR. eGFR is a better risk assessment parameter than SCr for predicting MACE and overall mortality in ACS patients.
