    Postoperative cognitive dysfunction (POCD) is cognitive decline after surgery. The authors hypothesized that gene-level changes could be involved in the pathogenesis of POCD. The present study evaluated the incidence of POCD and its associated differentially expressed genes. This was a prospective cohort study conducted on high-risk coronary artery bypass graft patients aged 40 to 75 years. POCD classification was based on a one standard deviation decline in the postoperative scores compared to the preoperative scores. The differentially expressed genes were identified using microarray analysis and validated using quantitative RT-PCR. Forty-six patients were recruited and completed the study. The incidence of POCD was identified using a set of neurocognitive assessments and found to be at 17% in these high-risk CABG patients. Six samples were selected for the gene expression analyses (3 non-POCD and 3 POCD samples). The findings showed five differentially expressed genes in the POCD group compared to the non-POCD group. The upregulated gene was ERFE, whereas the downregulated genes were KIR2DS2, KIR2DS3, KIR3DL2, and LIM2. According to the results, the gene expression profiles of POCD can be used to find potential proteins for POCD diagnostic and predictive biomarkers. Understanding the molecular mechanism of POCD development will further lead to early detection and intervention to reduce the severity of POCD, and hence, reduce the mortality and morbidity rate due to the condition.

    Unrecognized chest tube entrapment by surgical closure is a technical error. We present a rare case of chest tube entrapment that was successfully treated with a simple and safe solution in an elderly man after coronary artery bypass grafting (CABG). We visualized the suture using a small endoscope through the chest tube and incised it with the help of thoracoscopic scissors. The tube was then removed without the need for surgical exploration.

    The best management of asymptomatic carotid artery disease in patient who needs coronary bypass remains controversial. We report the neurological outcome of four patients with asymptomatic unilateral significant carotid artery disease who underwent conventional coronary bypass without carotid revascularization. Our review highlighted the risk of perioperative stroke is not increased despite carotid revascularization was not performed. Asymptomatic carotid artery disease is not the cause for cerebral infarct but soft aortic atheroma encountered during surgery is the main culprit.

    Coronary artery surgery as we know it today, has undergone rapid evolution since its introduction in the late 1960's, resulting, not surprisingly, in much confusion. In an attempt to present the state of the art, a collective review of the literature, coupled with the experiences with 118 patients is presented and discussed. The modern surgical management of patients with obliterative coronary artery disease is designed to relieve symptoms, prolong life and identify patients at high risk of premature death or myocardial infarction if they were to continue with medical management. Though the most common indication for surgery is persistent limitation of life style by severe symptoms, management is influenced by the strong association between such symptoms and increased mortality. During the short history of coronary bypass surgery, other indications for operation have been influenced by a combination of lessons from the past and hopes for the future. In addition, advances in technology have produced an enormous impetus for improvements in patient evaluation, surgical technique and postoperative care. As these advances continue and as more and more late results of surgery become available, answers to questions about surgery may increasingly be deduced from lessons rather than from hopes. As a result of these changes, an aura of confusion has gradually crept into the scene. It is hoped that this collective review, together with experiences gained from a personal series of 118 patients over a 3 year period from 1984 to 1986, will put into proper perspective, the state of the art of surgical management of coronary artery disease today.

    INTRODUCTION: Preoperative dialysis-dependent renal failure is a strong independent risk factor for in-hospital mortality and morbidity after open heart surgery. This retrospective study analyses the early outcome in dialysis-dependent renal failure patients who underwent elective open-heart surgery in the Institut Jantung Negara (IJN).

    METHODS: We retrospectively analyse a series of 228 consecutive postoperative patients with dialysis-dependent (end stage renal failure (ESRF)) admitted to the adult cardiothoracic ICU in IJN between January 2012 and December 2016.

    RESULTS: The overall early mortality rate included 34 patients (15.8%). Patients with ESRF underwent combined procedure recorded a very high mortality rate at 56.3%. Twenty-four patients (11.2%) needed resternotomy for postoperative bleeding or cardiac temponade. Postoperative mediastinitis rate was high, involving 13 patients (6%). The neurological and gastrointestinal complications rate were recorded at 2.3% (5 patients) and 6% (13 patients) respectively. In the group of patients (n=199) with sinus rhythm during the preoperative period, 100 patients (50.3%) developed postoperative AF. 77 patients (35.8%) stayed in hospital for more than 14 days.

    CONCLUSIONS: dialysis-dependent patients undergoing cardiac surgery poses higher perioperative risk of mortality and morbidity of 3-4 times higher compared to those patients with normal renal function. IJN shows acceptable perioperative risk of mortality and morbidity which is comparable to other centres.

    A prospective study was carried out to compare the outcomes of patients with preexisting non-dialysis-dependent renal dysfunction who underwent coronary artery bypass grafting with or without cardiopulmonary bypass. Elective off-pump coronary artery bypass was performed in 29 patients with renal dysfunction. Their results were compared with those of a similar group of 35 patients who underwent the conventional on-pump coronary artery grafting. There was a significant deterioration in creatinine clearance in the on-pump group on days 1, 2, and 4 after surgery, while creatinine clearance in the off-pump group remained close to the baseline level. Both groups had improved to the preoperative creatinine clearance values on follow-up at 4 weeks. It was concluded that off-pump surgery provided better renal protection than the conventional on-pump technique in patients with preexisting non-dialysis-dependent renal dysfunction.

    Kawasaki disease is primarily a condition that affects young children and it is associated with cardiac morbidity and mortality. This disease has been known to cause coronary artery aneurysms which occurs as a sequelae of vasculitis. The progression of triple vessel disease in adult which results from cardiac complications from Kawasaki disease is rare. We report a case of a young man with history of Kawasaki disease at infancy presenting with triple vessel disease requiring cardiac bypass surgery at the age of 20 years old.

    We present a case report of a 60-year-old Malay man who was undergoing an urgent coronary artery bypass graft (CABG) operation when a well encapsulated thymoma-like tumor was found incidentally. Total thymectomy was performed together with the CABG. Histopathological report of the tumor, however, confirmed a rare thymic carcinoid. The clinical features, management, and outcome of surgery are discussed.

    A personal series of 163 patients who underwent coronary artery bypass surgery (CABG) in the University Hospital, Kuala Lumpur between March 1988 and December 1990 were reviewed retrospectively to determine factors affecting hospital morbidity and mortality. One hundred and thirty eight were elective cases while 25 patients underwent emergency CABG surgery. Of these, 15 patients had recent myocardial infarction, with unstable haemodynamics or post infarct angina; six had failed angioplasty procedures and four patients immediately following coronary angiogram. The elective hospital mortality rate was 2.2% (three cases) and there were two deaths in the emergency group. Pre-operatively 20 patients (13%) had very poor left ventricular function of less than 30% ejection fraction. Significant improvement in ejection fraction was observed following surgery. The follow-up periods were between three months to three years. Ninety eight percent of patients showed improvement in their functional status (NYHA classification) in relation to angina and exercise performance.

    We present an interesting but high-risk case of an obese male patient aged 56 years with dextrocardia and a left diaphragmatic hernia. Anterior myocardial infarction was diagnosed in 1994, and the patient later presented with a history of unstable angina. The diagnosis for this chronic smoker was triple-vessel disease, impaired left ventricular function, chronic renal failure, chronic bronchitis, impaired lung function, pulmonary hypertension, hypertension, diabetes, and chronic active gastritis (EuroSCORE of 10). The patient underwent successful off-pump coronary artery bypass grafting with 3 saphenous vein grafts to the left anterior descending, obtuse marginal, and right posterior descending arteries. He was discharged home 8 days later.

    The revision of an internal mammary artery graft anastomosis because of a technical error can be time-consuming and complicated and may lead to complications. Here, we describe the technical details and our early experience of using a standard transit-time flowmeter to exclude technical errors and facilitate rapid decision making for anastomosis revision in an arrested heart during aortic cross-clamping in the absence of ultrasound guidance.

    BACKGROUND: The Short Form 36 (SF-36) is a scoring system comprising of 36 items categorized into eight constructs corresponding to patients' health-related quality of life. It has been used extensively in various countries on different sub-populations and used to indicate the health status and help to ascertain the effect of clinical interventions on the particular population.

    OBJECTIVE: To examine the psychometric properties of the Malay version of SF-36 (Malay SF-36) summated rating scales and validate the scale among post-coronary artery bypass grafting surgery (CABG) patients at the National Heart Institute (IJN), Kuala Lumpur.

    METHODS: Five hundred and nine post-CABG patients at the IJN, Malaysia completed the questionnaires between 1 July and 31 December 2017. Psychometric tests endorsed by the "International Quality of Life Assessment Project" were utilised.

    RESULTS: The data quality was excellent with a high questionnaire completion rate (100%). As hypothesized, the ordering of item means within scales was clustered. In unison, scaling assumptions were satisfied. Good discriminant validity was shown between subsets of patients with various levels of health status. Notwithstanding, there were probably translation issues of the Physical Functioning scale which showed small ceiling effects. We clearly observed high ceiling and floor effects in both Role Physical and Role Emotional scale most probably attributed to the dichotomous style of their choice of responses. Cronbach alpha values of the eight scales ranged from 0.73 to 0.90, showing good internal consistency reliability. Confirmatory Factor Analysis (CFA) confirmed the 8-factor solution and Composite Reliability revealed internal consistency reliability except for Vitality and Social Functioning. Based on the Average Variance Extracted (AVE), convergent validity was adequate except for two domains. Discriminant Validity is good for the eight constructs as the √AVE are generally higher than the correlation coefficients between the latent constructs.

    CONCLUSION: The scoring for the Malay SF-36 based on the summated ratings method was proven to be valid to be applied in our local clinical population. The CFA, fitness estimates, reliability and validity assessments suggest that the Malay version of SF36 is a valid and reliable instrument. However, further work is warranted to further refine the convergent validity and reliability of some scales.
