ABSTRACT
INTRODUCTION: Heart valve disease comprises a cluster of conditions affecting the aortic, mitral, pulmonary and tricuspid valves. This paper reviews all the research on heart valve disease in Malaysia published between the years 2000- 2016. METHODS: The methodology was based on the search process described in the paper, "Bibliography of clinical research in Malaysia: methods and brief results". The search databases included PubMed, Scopus and several Malaysian journals such as MyJurnal and UKM Journal Repository, by using the following keywords: (heart valve disease OR infective endocarditis OR rheumatic heart disease) and (Malaysia). RESULTS: In all 94 papers were identified of which 39 papers were selected and reviewed on the basis of their relevance. The local studies contributed to the knowledge and understanding of the epidemiology, aetiology, pathophysiology, clinical presentations, investigations, treatment, and outcomes of heart valve disease in the country. DISCUSSION: The clinical relevance of the studies performed in the country is discussed along with recommendations for future research.

Anomalous Aortic Origin of a Coronary Artery (AAOCA) is a rare anomaly of the coronary artery with a considerable risk of sudden cardiac death due to ischaemia of the heart. Symptoms may include chest pain on exertion, breathlessness or dizziness. We encountered a case of a 46- year-old female who complained of exertional chest pain with a positive-stress test and subsequently diagnosed with AAOCA through CT angiography (CTA). She successfully underwent a coronary artery bypass graft (CABG) surgery using a saphenous vein graft with uneventful recovery. Right internal mammary artery (RIMA) was not used as it was flimsy and the flow was very poor.

INTRODUCTION: Aortic disease includes conditions such as chronic aortic aneurysms, acute aortic syndromes and congenital aortic abnormalities, amongst others. This paper reviews all research on aortic disease performed in Malaysia and published between 2000-2016. METHODS: A literature search was conducted in PubMed, Scopus, MyJurnal and the UKM Journal Repository. The search process was based on a previously published methodology. The medical subject headings (MeSH) search terms used were "aortic", "aorta" and "Malaysia". RESULTS: Two-hundred-thirteen papers were identified, of which 60 papers were selected and reviewed on the basis of their relevance. The epidemiology, pathophysiology, clinical presentations, case reports, investigations, treatment and outcomes of aortic disease in Malaysia were reviewed and summarised. The clinical relevance of the studies performed are discussed. CONCLUSION: The review provided an insight into the pathophysiology, prevalence and epidemiology of aortic diseases in Malaysia, how the condition is managed, and the outcomes of treatment. Limitations of the research performed in Malaysia to date were identified and recommendations for further research and improvement in clinical practice were recommended.

Coronary artery disease is the major cause of mortality and morbidity in Malaysia and worldwide. This paper reviews all research and publications on coronary artery disease in Malaysia published between 2000-2015. 508 papers were identified of which 146 papers were selected and reviewed on the basis of their relevance. The epidemiology, etiology, risk factors, prevention, assessment, treatment, and outcomes of coronary artery disease in the country are reviewed and summarized. The clinical relevance of the studies done in the country are discussed along with recommendations for future research.

Lung cancer is a major cause of mortality and morbidity in Malaysia and worldwide. This paper reviews all research and publications on lung cancer in Malaysia published between 2000-2015. 89 papers were identified, of which 64 papers were selected and reviewed on the basis of their relevance to the review. The epidemiology, risk factors, cell types, clinical presentation, diagnosis, treatment, outcomes, prevention, and the social impact of lung cancer in the country are reviewed and summarized. The clinical relevance of the studies done in the country are discussed along with recommendations for future research.

Increasing numbers of patients are being referred for repeat cardiac procedures and redo-sternotomy is technically more arduous as well as time consuming. We describe our unique technique to overcome this challenging task by hyperinflating the lungs as a useful manoeuvre.

Changes in pulmonary permeability provide a partial measure of the clinical impact of biocompatible oxygenator use during cardiopulmonary bypass surgery. Previous research has shown that the clearance rate of 99mTc-labelled diethylene triamine penta-acetic acid (99mTc-DTPA) aerosol from the lungs is increased following cardiopulmonary bypass, resulting from an increase in pulmonary permeability. The aerosol clearance rate has been shown to return to normal after a period of 7 days. A blind trial was set up to assess the clinical impact of a biocompatible, Trillium-coated oxygenator compared with a standard oxygenator. In a group of 25 patients 99mTc-DTPA aerosol studies were carried out prior to cardiopulmonary bypass surgery for mitral valve surgery. Repeat studies were undertaken 3-4 h and 24-28 h after surgery. Analysis of the rates of pulmonary clearance reproduced the trends seen in earlier research. There was however no statistically significant difference in the variation of serial clearance times between the groups of patients undergoing surgery using the Trillium-coated oxygenators and those using the standard oxygenators.
