Fulltext Left atrial myxoma: three case reports

Siew TY, Zambahari R

Med J Malaysia, 1986 Sep;41(3):229-32.

The left atrial myxoma is important not only because of its relative frequency and diagnostic difficulty but because it can be successfully removed by surgery. However, if untreated, it invariably leads to death. We report three cases seen at the Cardiology Department, General Hospital, Kuala Lumpur in 1985.

Fulltext Retrieval of detached fragment of central venous pressure catheter (CVP) lodged in the right ventricle and pulmonary artery: a case report

Sakijan AS, Zambahari R, Annuar Z, Yahya O, Ali J

Med J Malaysia, 1990 Dec;45(4):340-3.

PMID: 2152057

A successful retrieval of a detached segment of a CVP catheter by percutaneous right transfemoral venous route, using a Dotter intravascular retriever basket, is reported. The procedure was monitored under fluoroscopy. Only local anaesthesia, which was infiltrated around the puncture site, was given to the patient. No significant complication was encountered. Successful retrieval of the detached catheter fragment by percutaneous means obviates the need for thoracotomy.

Alwi M, Hamid ZA, Zambahari R

Br Heart J, 1992 Jul;68(1):6-8.

PMID: 1515294

Continuous wave Doppler recordings of the turbulent jet through the restrictive orifice of a left atrial partition in a patient with corrected transposition of the great arteries and cor triatriatum showed alternate bands of high intensity diastolic and low intensity systolic signals with preservation of the normal configuration of the diastolic E and A peaks. It is thought that Doppler studies in cor triatriatum will provide useful complementary haemodynamic information in the echocardiographic diagnosis of this anomaly.

Percutaneous transvenous mitral commissurotomy in patients with severe kyphoscoliosis

Ramasamy D, Zambahari R, Fu M, Yeh KH, Hung JS

Cathet Cardiovasc Diagn, 1993 Sep;30(1):40-4.

PMID: 8402863

Because transseptal catheterization is felt to be contraindicated in patients with severe kyphoscoliosis, there have been no reports of percutaneous transvenous mitral commissurotomy performed in such patients. This report describes percutaneous transvenous mitral commissurotomy in three patients with severe thoracic kyphoscoliosis, with special emphasis on the transseptal puncture technique. Biplane right atrial angiography and the contrast septal flush method are very useful in landmark selection for a safe transseptal puncture.

Am J Cardiol, 1997 May 15;79(10):1430-2.

PMID: 9165178 DOI: 10.1016/s0002-9149(97)00160-4

Two hundred eleven patients with small- to moderate-sized native patent ductus arteriosus underwent closure using Gianturco coils, employing the transvenous multiple catheter approach. Short-term results showed a high rate of complete occlusion and a potential long-term complication of mild left pulmonary artery stenosis in a small number of patients.

Transcatheter closure of multiple muscular ventricular septal defects using Gianturco coils

Latiff HA, Alwi M, Kandhavel G, Samion H, Zambahari R

Ann Thorac Surg, 1999 Oct;68(4):1400-1.

PMID: 10543517

A 10-month-old boy underwent operation to close a large secundum atrial septal defect and multiple muscular ventricular septal defects. Closure of the ventricular septal defects was unsuccessful and led to worsening cardiac failure and inability to wean the patient from mechanical ventilation. Transcatheter closure of the ventricular septal defects using Gianturco coils was undertaken. This technique is an effective alternative for closure of multiple muscular ventricular septal defects in infants and small children.

PMID: 17313616

Several therapeutic approaches have been developed to improve the outcome among patients with acute coronary syndrome (ACS). However, treatment with antithrombotic therapies such as oral glycoprotein IIb/IIIa inhibitors has been limited by the lack of efficacy and excess bleeding complications. As the publication of the landmark study Clopidogrel in Unstable Angina to Prevent Recurrent Events (CURE), the clinical benefit of early and intermediate-term use of combined antiplatelet agents--clopidogrel plus aspirin--in non-ST-segment elevation myocardial infarction (NSTEMI) patients became evident. Pretreatment and intermediate-term therapy with clopidogrel in NSTEMI ACS patients undergoing percutaneous coronary intervention (PCI) was further supported by the PCI-CURE trial. Recently, the results of two major trials Clopidogrel as Adjunctive Reperfusion Therapy-Thrombolysis in Myocardial Infarction 28, Clopidogrel and Metoprolol in Myocardial Infarction Trial established the pivotal role of clopidogrel in the other spectrum of ACS-STEMI. Coupled with the results from previous multicentre trials, these two studies provide a guide for the early and long-term use of clopidogrel in the whole spectrum of ACS. A review summarising the results of the recent clinical trials and a discussion on its implications for the clinical management of ACS is presented.

Current status of cholesterol goal attainment after statin therapy among patients with hypercholesterolemia in Asian countries and region: the Return on Expenditure Achieved for Lipid Therapy in Asia (REALITY-Asia) study

Kim HS, Wu Y, Lin SJ, Deerochanawong C, Zambahari R, Zhao L, et al.

Curr Med Res Opin, 2008 Jul;24(7):1951-63.

PMID: 18547466 DOI: 10.1185/03007990802138731

BACKGROUND: Data on achieving National Cholesterol Education Program Adult Treatment Panel III (ATP III) goals in Asia are limited.

OBJECTIVE: To examine treatment patterns, goal attainment, and factors influencing treatment among patients in 6 Asian countries who were taking statins.

METHODS: A retrospective cohort study was conducted in China, Korea, Malaysia, Singapore, Taiwan, and Thailand, where 437 physicians (41% cardiologists) recruited adults with hypercholesterolemia newly initiated on statin monotherapy.

RESULTS: Of 2622 patients meeting inclusion and exclusion criteria, approximately 66% had coronary heart disease (CHD)/diabetes mellitus, 24% had no CHD but > or =2 risk factors, and 10% had no CHD and <2 risk factors. Most patients ( approximately 90%) received statins at medium or lower equipotency doses. Across all cardiovascular risk categories, 48% of patients attained ATP III targets for low-density lipoprotein cholesterol (LDL-C), including 38% of those with CHD/diabetes (goal: <100 mg/dL), 62% of those without CHD but with > or =2 risk factors (goal: <130 mg/dL), and 81% of those without CHD and <2 risk factors (goal: <160 mg/dL). Most patients who achieved goals did so within the first 3 months. Increasing age (odds ratio (OR)=1.015 per 1-year increment; 95% confidence interval (CI)=1.005-1.206; p=0.0038) and initial statin potency (OR=2.253; 95% CI=1.364-3.722; p=0.0015) were directly associated with goal attainment, whereas increased cardiovascular risk (OR=0.085; 95% CI=0.053-0.134; p<0.0001 for CHD/diabetes mellitus at baseline compared with <2 risk factors,) and baseline LDL-C (OR=0.990; 95% CI=0.987-0.993); p<0.0001 per 1-mg/dL increment) were inversely associated with LDL-C goal achievement. Limitations of this study include potential differences in treatment settings and cardiovascular risk factors between different countries and centers. In addition, the effects on cholesterol goal achievement of concomitant changes in lifestyle were not assessed.

CONCLUSION: LDL-C goal attainment is low in Asians, particularly those with CHD/diabetes. More effective patient monitoring, treatments, including combining regimens and dose titration, and adherence to these treatments along with therapeutic lifestyle counseling may facilitate goal attainment.

PMID: 22525668 DOI: 10.1038/nrcardio.2012.59

Cardiovascular disease (CVD) is an under-recognized major health problem among women in South-East Asia. The prevalence of cardiovascular risk factors such as hypertension, diabetes mellitus, dyslipidemia, physical inactivity, and being overweight or obese has shown a significantly increasing trend among women in the region, with the exception of Singapore. The problem is compounded by low awareness that CVD is a health problem for women as well as for men, by misconceptions about the disease, and by the lack of suitable, locally available health literature. Efforts have been made by the national heart associations and other organizations to increase heart health awareness and promote healthy lifestyles. Singapore initiated these prevention programs in the early 1990s and has been successful in reducing the prevalence of cardiovascular risk factors. The governments of the region, in accordance with the Noncommunicable Disease Alliance, have begun implementing appropriate preventive strategies and improving health-delivery systems. However, psychological, social, and cultural barriers to cardiovascular health awareness in women need to be addressed before these programs can be fully and successfully implemented.
