Percutaneous trans-mitral commissurotomy (PTMC) has been practiced with good results in the world since Inoue introduced it in 1982. \u0000Objective: The aim of this study was to audit the procedural success, in- hospital outcome in patients undergoing PTMC in our set up. Study Design: Observational cross sectional study. Place and Duration: The study was conducted in northern division of Bangladesh with the collaboration of department of cardiology, Rangpur Medical College Hospital, Rangpur & Zia Heart Foundation, Dinazpur from February 2018 to November 2019. \u0000Materials and Methods: Total Thirty patients who fulfill the inclusion and exclusion criteria for PTMC was enrolled in this study. Among them the procedural success & immediate results were assessed. \u0000Results: Among 30 patients , 22(73.33%) were female and 8(26.66%) were male showing a female predominance. The mean age was 28.28±8.4.The procedure was successful in 29(96.66%) patients. In 1(3.3%) patient, we failed due to inability to puncture the septum for unfavourable anatomy. There was no mortality related to the procedure, no systemic embolization but one patient (3.33%) had significant MR(G II ). Pre PTMC mean MVA (cm2) was 0.801± 0.1325 and post PTMC it was 1.545± 0.292 cm2. Mean MVPG pre PTMC was 27.108±5.94 mmHg and post PTMC , 6.61±5.008 mmHg with significant p value 0.0001. Mean LA pressure before procedure was 28.65±8.456 mmHg and post PTMC, 11.27±6.34 and p value was 0.0001. Most of the patients 25(83.3%) before PTMC were in severe pulmonary hypertension and after PTMC most of the patients 21(70%) were in mild pulmonary hypertension.We successfully done 7 special cases like pregnancy, re do cases, H/O CVD etc. \u0000Conclusions: We conclude that PTMC is a safe procedure in experienced hand with good success rate and optimal results even in patients with special problems like pregnancy, previous CVA and redo cases. \u0000University Heart Journal Vol. 17, No. 1, Jan 2021; 47-54","PeriodicalId":23424,"journal":{"name":"University Heart Journal","volume":"299 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2020-12-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"88404185","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Clinical importance of hyponatremia in ST-elevated acute myocardial infarction (STEMI) is an important topic of study among present researchers. \u0000Objective: To assess the outcomes and prognostic implications of early development of hyponatremia inhospitalized acute ST-elevated myocardial infarction patients. \u0000Methods: This is a prospective observational study performed in the department of Cardiology, Combined Military Hospital (CMH), Dhaka from July 2018 to June 2019. A purposive sampling technique was used on 82 patients with ST-elevated acute myocardial infarction admitted in CCU and treated with thrombolysis. They were evaluated for serum sodium level at admission and at 48 hours after admission. Here sodium concentration <135 mmol/L is defined as Hyponartemia. Fourty one patients with hyponatremia were included in Group-I and 41 patients with normal sodium level were included in Group-II. Then the in-hospital outcome variables were analyzed. \u0000Results: Among the study population 86.58% were male and 13.42% were female. Age range was 25 years to 74 years. Considering risk factors highest percentage of study population in group- I had hypertension (60.97%) followed by dyslipidemia (51.21%), diabetes mellitus (51.21%), history of smoking (53.60%), and family history of Coronary Artery Disease (CAD) (31.14%). There were five outcome variables such as heart failure, cardiogenic shock, arrhythmia, duration of hospital stay and death. 10 patients died in Group-I and 2 patients died in Group-II. Among the outcome variables death, heart failure and hospital stay was more in Group-I and was statistically significant. hospital outcome of study population according to serum sodium level. Considering in hospital outcome heart failure occurred in 14 patients (p= .001), arrhythmia developed in 17 patients (p=0.108), cardiogenic shock occurred in 9 patients (p=0.354) and death occurred in 10 patients (p=0.002).

The present research was aimed at assessment of myocardial viability and prediction of left ventricular functional recovery in patients after acute anterior ST-elevated myocardial infarction using Tissue Doppler strain. \u0000Methods: In this prospective observational research, 47 patients admitted into the hospital with acute anterior ST-elevated myocardial infarction were included. All patients underwent two-dimensional and strain echocardiography within 48-72 hours of admission. Follow up two-dimensional echocardiography had performed at 6 months after baseline examination. \u0000Results: Total 47 patients (mean age, 57±5 years) underwent two-dimensional and strain echocardiography within 48-72 hours of admission. Significant relations were observed between baseline global systolic lengthening strain and wall motion score index (r=0.67), change in left ventricular ejection fraction (LVEF, r= -.844), Global Ses (r=.441) and on admission troponin I (r =0.397). At 6-months follow-up, LV ejection fraction was reassessed. Patients with absolute improvement in LV ejection fraction ≥5% at 6-months follow-up (n=24; 51%) had a higher (more negative) baseline global Ses strain (P<0.001) and lower global systolic lengthening (P<.001).

The number of CAD is also increasing in Bangladesh. Rangpur Medical College & Hospital is also providing cardiovascular services to populations from urban, semiurban and rural population of northern region of the country. It started coronary angiography services from June 2011. This paper aims to analyze pattern of coronary artery occlusion in patients undergoing coronary angiography during January to October 2019. \u0000Methods: This was a retrospective observational study conducted in the cardiology department. There were a total of 308 cases of diagnostic angiography and coronary interventions done in Rangpur Medical College & Hospital from January to October 2019. Among them 308 cases of coronary angiography done for Acute Coronary Syndrome and Stable Angina, were analyzed using SPSS (Statistical Package for Social Science), version 17. \u0000Results: Males were higher in number than females and majority of the patients were at or above 50 years of age. Out of 308 cases 225 had Acute Coronary Syndrome (ACS) and 83 had Stable Angina. 54 out of 308 were found to have normal coronaries. 25 patient with ACS had normal coronary. Out of all the patients with coronary stenosis, 19 had left main disease, 59 had SVD, 62 has DVD, 71 patient had TVD. 9 patients had CTO. 159 patients had severe coronary stenosis. 117 out of 225 ACS patient had more than one coronary artery involved, which is significantly higher than the stable angina group ( p<0.01). Severe stenosis was found to be more common in ACS group (p<0.003) when compared to the stable angina group. \u0000Conclusion: There has been a change with regard to clinical presentation and onset of risk factors for CAD at young age, but the load of atherosclerotic burden and pattern of involvement of coronary arteries have not changed in Elder group. Coronary angiography is a useful diagnostic and therapeutic tool for CAD. Coronary status is significantly different in ACS and stable angina. ACS has more chance of having multivessel stenosis whereas stable angina has single vessel, less severe or normal coronaries. Severity of stenosis is also high in ACS than in stable angina. \u0000University Heart Journal Vol. 17, No. 1, Jan 2021; 55-59","PeriodicalId":23424,"journal":{"name":"University Heart Journal","volume":"11 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2020-12-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"81829389","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
