A Case of Congenital Coronary Ostial Stenosis with Systemic Lupus Erythematosus.

Congenital coronary ostial stenosis or atresia (COSA) is a spectrum of rare developmental conditions with different pathophysiologic mechanisms and clinical implications. Although COSA includes various entities, these entities have two features in common. First the defect is congenital, although it may progress during pre-natal and post natal life. Second the developmental defect may cause ostial or proximal coronary obstruction (that is stenosis or atresia). Coronary ostial stenosis or atresia affects the left coronary (L-COSA) more frequently than it does the right coronary artery. Systemic Lupus Erythematosus (SLE) is not an uncommon disease in young female, but combination of congenital coronary ostial stenosis with systemic lupus erythematosus make the case very rarer. Here we presented A 17 years old girl got admitted to Bangabandhu Sheikh Mujib Medical University, Bangladesh for evaluation of on and off chest pain of CCS-III to CCS-IV for 1 day on 17 September 2019.

Echocardiographic Assessment of Valvular Involvement in Chronic Rheumatic Heart Disease in BSMMU, Bangladesh.

Rheumatic heart disease (RHD) is a disease of poverty, is almost entirely preventable, and is the most common cardiovascular disease worldwide in those under 25 years especially in the developing county like Bangladesh. RHD is caused by acute rheumatic fever (ARF) which typically results in cumulative valvular lesions that may present clinically after a number of years of sub-clinical disease. It has a progressive course and patients usually may require valve repair/replacement in future. Echocardiography is an easily available, non-invasive, widely used, standard tool for diagnosis and evaluation of RHD. But there is scarcity of echocardiographic study of Valvular Involvement in Chronic Rheumatic Heart Disease (CHRD) in Bangladesh. This study was aimed to utilize echocardiography as a tool to evaluate patients of CRHD in Bangabandhu Sheikh Mujib Medical University (BSMMU), Dhaka, Bangladesh. This observational study was conducted in the Department of Cardiology, BSMMU from September 2018 to August 2019. Echocardiography was done in each patient only once with VividE9®machine. Among 1350 echocardiography, 101 patients (7.5%) were diagnosed as RHD including post valve replacement patients. The mean age of the patients was 40±14 years and 64.34% were female. Mitral stenosis (MS) was the commonest lesion in 84.15% followed by mitral regurgitation (MR) in 66.33%, tricuspid regurgitation (TR) in 57.43%, aortic regurgitation (AR) in 49.51%, aortic stenosis (AS) in 26.74% and pulmonary regurgitation in 10.89%. The frequency of complications like pulmonary hypertension, heart failure, atrial fibrillation (AF), LA thrombus, stroke and infective endocarditis was 67.33%, 61.05%, 18.81%, 6.93%, 3.96% and 0.99% respectively. History of Rheumatic fever was present only in 10.89% patient. Mitral stenosis was the commonest lesion seen mostly in female and most common complication was pulmonary hypertension. Mean age of patients in this study was higher than other contemporary studies and frequency as well as severity of complications was also more in female.

Feasibility and Safety of Distal Transradial Access in the Anatomical Snuffbox for Coronary Angiography and Intervention.

Distal transradial access in the anatomical snuffbox has advantages over standard proximal access in terms of patient and operator comfort levels and risk of ischemia. Radial artery preservation could be a relevant issue in patients requiring multiple radial artery procedures and coronary bypass with the use of a radial graft or construction of Arterio-Venous fistula in patient of chronic kidney disease. One relevant drawback is the challenging puncture of a small and weak artery, with a steeper learning curve. The study was aimed at proving feasibility and safety of distal transradial access in the anatomical snuffbox. A total of 100 patients were assigned to perform coronary angiogram or intervention through distal transradial access in the anatomical snuffbox from January 2018 to June 2018 in this unit of the University Cardiac Center (UCC), Bangabandhu Sheikh Mujib Medical University (BSMMU), Dhaka, Bangladesh. All of them had normal pulse in their distal radial artery. Both right and left distal radial artery were used and demographic features & complications were recorded during hospital stay. Statistical analysis was done through SPSS version 19. The overall feasibility was 98%, greater than expected in this early clinical experience, with 98 successful accesses out of 100 patients. There was failure to access of distal radial artery in two cases which may be due to hypoplastic/vasospastic distal radial artery. Despite all it can be said that it was very much safe as there was no hand ischemia, hematoma, numbness or proximal radial arterial occlusion. Distal transradial access in the anatomical snuffbox for coronary angiography and intervention is a safe and feasible option for both patients and operators.

Visceral Adiposity Index Score is the Better Predictor of Clinical and Coronary Angiographic Severity Assessment than Other Adiposity Indices in Patients with Acute Coronary Syndrome.

Acute coronary syndrome (ACS) is one of the leading causes of death throughout the world and obesity especially visceral adiposity is one of the important concerns globally due to its huge impact on coronary artery disease particularly on ACS. There are several traditional methods like BMI, WC, WHR, WHtR etc. but none of these can measure visceral fat accurately. In this regard visceral adiposity index (VAI) is a novel sex specific index which has significant correlation with visceral adiposity and can express the distribution as well as function of visceral fat precisely. This cross sectional study was done in the Cardiology Department of National Institute of Cardiovascular Diseases, Dhaka, Bangladesh from August 2015 to July 2016 to compare the VAI with other adiposity indices for clinical and coronary angiographic severity assessment in patients with acute coronary syndrome. A total of 200 patients (Case 100 patients of ACS and Control 100 patients of non ACS) were included. Afterward clinical, biochemical, echocardiographic and coronary artery angiographic indexes determined by Gensini score were acquired. Adiposity indices like BMI, Waist and Hip circumference, Waist Hip and Waist Height ratio (WHR, WHtR) and finally VAI were calculated using appropriate formula. Patient with ACS had more severe form of clinical features like severe chest pain & shortness of breath (p=0.001), pulse, BP, abnormal precordial findings, BMI, WC, WHR, WHtR, HC, VAI (p=0.001) and angiographic severity (p=0.001) than non ACS group. Multivariate binary logistic regression analysis for clinical and coronary angiographic severity assessment (GS>36) by adiposity indices showed VAI was the better predictor of clinical and coronary angiographic severity assessment with OR's being 5.61 than others. An ROC curve was plotted for each adiposity indices for clinical and coronary angiographic severity assessment showed VAI to have the maximal AUC. A VAI of OR-5.61 was provided as the cutoff value which had a sensitivity of 73.3% and specificity of 76.6% (AUROC=0.839, CI-0.760-0.918, p<0.001) which indicates better than other adiposity indices in patients under study. VAI is an excellent, simple, noninvasive tool to detect the visceral adipose mass & was markedly associated with the clinical and coronary angiographic severity assessment in patients with ACS.

Comparison between Glyceryl Trinitrate and Trimetazidine in Ischaemic Cardiomyopathy Patients.

Ischaemic cardiomyopathy (ICM) remains a major health problem, both in developed and developing countries like Bangladesh where it causes a significant number of morbidity and mortality. The treatment and outcome of ICM chiefly depends on the presence and extent of hibernating myocardium. In this regard addressing anginal symptoms is the key to patients' comfort as well to achieving the goal of treatment. Glyceryl trinitrate (GTN) and trimetazidine (TMZ) are two widely used drugs for relieving angina. This pilot study was designed to answer some of the confusions and controversies regarding their use and to bring precision in decision making in the treatment of ICM. Here, comparison of GTN and trimetazidine were done by assessing the symptoms by NYHA and CCS class following their use in ICM patients, admitted in Bangabandhu Sheikh Mujib Medical University (BSMMU), Dhaka, Bangladesh from 15th October, 2015 to 15th April, 2016, who were randomly placed in two groups in a prospective manner. Most of the patients were in age group 51-60 years and were male in both the groups. It was observed that there was no significant difference in NYHA and CCS class at base line and at discharge between two groups (p>0.05). But statistically significant (p<0.05), improvement noted at 6 weeks and 12 weeks in GTN group in comparison to trimetazidine group. GTN stood out to be a better option than TMZ in the treatment of ICM. Moreover GTN is a cheaper option than TMZ.
