Abstract: For many years, cardiovascular disease (CVD) was regarded as a lifestyle disease primarily affecting ageing, affluent populations. This is reflected in the virtual absence of global policies concerned with CVD control in poor and rich countries alike. However, CVD and other non-communicable diseases (NCDs), including cancer, chronic respiratory disease and diabetes, account for nearly two-thirds (63%) of global deaths, with the majority of deaths from NCDs (80%) occurring in low- and middle-income countries (LMICs).

Abstract: Aim : To describe dietary habits and potential nutritional deficiencies in black African patients diagnosed with heart failure (HF).
Methods and Results : Dietary intake in 50 consecutively consenting HF patients (mean age: 47 ± 18 years, 54% female) attending a major hospital in Soweto, South Africa were surveyed using validated quantitative food frequency questionnaires. Food intakes, translated into nutrient data were compared with recommended values. In women, food choices likely to negatively impact on heart health included added sugar [consumed by 75%: median daily intake (interquartile range) 16 g (10-20)], sweet drinks [54%: 310 ml (85-400)] and salted snacks [61%: 15 g (2-17)]. Corresponding figures for men were added sugar [74%: 15 g (10-15)], sweet drinks [65%: 439 ml (71-670)] and salted snacks [74%: 15 g (4-22)]. The womens' intake of calcium, vitamin C and vitamin E was only 66, 37 and 40% of the age-specific requirement, respectively. For men, equivalent figures were 66, 87 and 67%. Mean sodium intake was 2 372 g/day for men and 1 972 g/day for women, 470 and 294% respectively, of recommended consumption levels.
Conclusions : The nutritional status of black African patients with HF could be improved by recommending healthier food choices and by reducing the intake of sweet drinks and excess salt.

Abstract: Background : We evaluated the patients who had had a Damus-Kaye-Stansel (DKS) operation for single-ventricular physiology with the aorta originating from a hypoplastic ventricle and the pulmonary artery from the systemic ventricle.
Methods : Seven patients who were operated on between May 2007 and November 2010 were evaluated retrospectively. The patients had been diagnosed with a transposed double-inlet left ventricle and triscuspid atresia, and had been waiting for a Fontan operation. Systemic outflow stenosis was defined echocardiographically as those with a gradient greater than 20 mmHg, and angiographically those with greater than 5 mmHg in the subaortic region.
Results : The mean age and weight of the patients was 15 ± 9.7 months and 8 ± 3.3 kg, respectively. The mean gradient between the systemic ventricle and the aorta was 35 ± 25 mmHg. This gradient decreased to 14.3 ± 4 mmHg postoperatively. The early hospital mortality was 14% (one patient). The mean extubation time and mean time in the intensive care unit (ICU) were 13 ± 7.3 hours and 2.2 ± 0.5 days, respectively. The mean follow-up time was 11 ± 2 months. No mortality and semi-lunar valve insufficiency were observed after discharge.
Conclusions : One of the major problems that occur while waiting for a Fontan operation is systemic ventricular hypertrophy and deterioration in the compliance of the ventricle due to systemic ventricular outflow stenosis. When the disadvantages of outflow resection are encountered, a DKS proves to be a good alternative.

Abstract: Background : Some studies have suggested that diastolic dysfunction precedes the clinical manifestation of hypertension. Whether changes in cardiac structure and function predate the clinical manifestation of hypertension later in life is now being investigated. The aim of this study was to assess the differences in cardiac structure and function between the offspring of hypertensive and normotensive parents.
Methods : Eighty normotensive offspring of hypertensive parents (OHyp) (41 females and 39 males) and 62 normotensive offspring of normotensive parents (ONorm) (31 males and 31 females) were recruited for echocardiography.
Results : The mean age was 25.0 (5.31) and 24.3 (3.60) years in the OHyp and ONorm participants, respectively (p = 0.369). Other baseline parameters were comparable between the two groups. Septal wall thickness in systole was higher in the OHyp than the ONorm subjects [1.3 (0.35) vs 1.1 (0.25), p = 0.0173]. Indexed left ventricular mass [28.1 (7.33) vs 27.5 (7.23), p = 0.631] and relative wall thickness [(0.3 (0.10) vs 0.3 (0.90), p = 0.280] were similar in the two groups. The offspring of hypertensives had lower deceleration time [149.9 (38.89) vs 169.0 (50.08) ms, p = 0.012], prolonged duration of pulmonary A reverse flow [113.5 (70.69) vs 81.7 (38.31) ms, p = 0.024], increased myocardial isovolumic relaxation time [173.4 (47.98) vs 156.1 (46.74) ms, p = 0.033] and a lower myocardial Em [0.2 (0.05) vs 0.3 (1.38), p = 0.037] and myocardial Em/Am ratio [1.6 (0.01) vs 2.1 (0.01), p = 0.019] than the offspring of normotensives.
Conclusion : This study showed that offspring of OHyp subjects had early diastolic functional abnormalities when compared with offspring of ONorm participants. Longitudinal studies are needed to determine the implications of this finding in this African population.

Abstract: Background : We determined the prevalence of general and central obesity and their relationship with blood pressure levels among adolescents in Abeokuta, Nigeria.
Methods : We selected 423 adolescents from seven schools in Abeokuta, Nigeria, using a multistage random-sampling technique. Body mass index (BMI), waist circumference (WC) and blood pressures were measured.
Results : Twenty-one (5%) children had general obesity and 109 (24.5%) had central obesity. Of those with general obesity, 20 (95.1%) children were centrally obese. With simple linear regression analysis, BMI and WC explained 10.7 and 8.4%, respectively of the variance in systolic blood pressure (SBP), and 3.6 and 2.7%, respectively of the variance in diastolic blood pressure (DBP). Following logistic regression analysis, BMI was the major factor determining SBP levels (OR 0.8, 95% CI: 0.65-0.99, p < 0.05).
Conclusion : BMI remains an important anthropometric screening tool for high blood pressure in Nigerian adolescents.

Abstract: Background : Older adults are disproportionately affected by hypertension, which is an established risk factor for cardiovascular disease. Despite these facts, no study on the prevalence, awareness, treatment and control on arterial hypertension in Senegal has been conducted, specifically among elderly people.
Methods : Five hundred people aged 50 years and older, living in the city of Dakar were interviewed. This sample was constructed using the combined quota method in order to strive for representativeness of the target population.
Results : Prevalence of hypertension was 65.4% in our sample. Half of those suffering from high blood pressure were aware of their problem and among the latter, 70% said they were on treatment. However, of these, only 17% had controlled arterial blood pressure. The only factor associated with awareness, treatment and control of hypertension was the frequency of doctor visits.
Conclusion : Improving follow-up health checks of older adults are necessary to limit the consequences of hypertension in Dakar.

Abstract: Introduction : Morbidity and mortality from diabetes are compounded by associated cardiovascular risk factors. For this reason, taking care of these risk factors is a public health goal.
In this study we evaluated the level of control of cardiovascular risk factors in black Africans with type 2 diabetes in Senegal.
Methods : Between March 2007 and July 2008, we recruited type 2 diabetes patients from outpatient care in a specialised hospital in Senegal. Data were collected on a survey form designed for this purpose. An electrocardiogram and laboratory examinations were also performed. The level of control of diabetes and associated cardiovascular risk factors were assessed, as recommended by the American Diabetes Association (ADA).
Results : A total of 318 type 2 diabetes subjects (237 women) were recruited. The average age was 58.2 ± 9.2 years (40-85). The mean duration of diabetes was 6.9 ± 5.9 years. The average glycaemic level was 1.4 ± 0.5 g/l and glycated haemoglobin was 7.6 ± 3.2%. The average length of patient follow up was 6.7 ± 6.1 years with a single annual consultation; 63.2% of the patients were on an insulin + biguanide combination, with good diabetes control (HbA1c < 7%) in 25% of cases. Antihypertensive drugs were prescribed in 28.1% of hypertensive patients. More than half (51.9%) of these hypertensive patients were treated with angiotensin converting enzyme inhibitors. Their blood pressure was well controlled (< 130/85 mmHg) in 5.4% of the hypertensive patients (10/185). The low-density lipoprotein (LDL) cholesterol goal was achieved in 18.5% of cases (5/27).
Conclusion : This study shows that the prevalence of cardiovascular risk factors is higher among black Africans suffering from type 2 diabetes. The control of these factors was not optimal in our study.
Introduction: La morbidité et la mortalité du diabète sont aggravées par l'association de facteurs de risque cardiovasculaire dont la prise en charge est un objectif de santé publique. Nous évaluons dans cette étude le niveau de contrôle des facteurs de risque cardio-vasculaire dans une population de diabétiques de type 2 noirs africains au Sénégal.
Méthodologie : Nous avons recruté, entre mars 2007 et juillet 2008, des diabétiques de type 2 suivis en ambulatoire en milieu hospitalier spécialisé au Sénégal. Les données ont été recueillies sur une fiche d'enquête conçue à cet effet. Un électrocardiogramme et des examens biologiques ont été aussi réalisés. Le niveau de contrôle du diabète et des facteurs de risque cardio-vasculaire associés a été évalué selon les recommandations de l'American Diabetes Association (ADA).
Résultats : Un total de 318 diabétiques de type 2 (237 femmes) ont été colligés. L'âge moyen était de 58.2 ± 9.2 ans (40-85). La durée moyenne d'évolution du diabète était de 6.9 ± 5.9 ans avec un taux moyen de glycémie de 1.4 ± 0.5 g/l et d'hémoglobine glyquée de 7.6 ± 3.2%. La durée moyenne du suivi des patients était de 6.7 ± 6.1 ans avec une seule consultation annuelle; 63.2% des patients étaient sous l'association biguanide + insuline avec un bon contrôle du diabète (HbA1c < 7%) dans 25% des cas. Les antihypertenseurs étaient prescrits chez 28.1% des hypertendus dont plus de la moitié (51.9%) sous inhibiteurs de l'enzyme de conversion de l'angiotensine avec un bon contrôle de la tension artérielle (< 130/85 mmHg) dans 5.4% des cas (10/185). L'objectif de LDL-cholestérol était atteint dans 18.5% des cas (5/27).
Conclusion : Cette étude montre que la prévalence des facteurs de risque cardio-vasculaire est élevé chez les diabétiques de type 2 noirs africains. Le contrôle de ces facteurs n'était pas optimal dans notre étude.

Abstract: The letter by Mullier in response to our article titled 'The grapefruit: an old wine in a new glass? Metabolic and cardiovascular perspectives' refers. The author states that amiodarone is not only a prodrug but also has inherent pharmacodynamic effects, just like its metabolite N-desethyamiodarone (N-DEA), which he correctly suggests could have even greater pharmacological effects than the parent compound. However, we need to emphasise that even though N-DEA has similar class III anti-arrythmic effects, it has faster sodium channel blockade and lower class IV effects than amiodarone.

Abstract: Background : We report the first single-centre experience in Africa with the Sensei X robotic navigation system in an unselected subset of patients with atrial fibrillation (AF).
Methods : Data were recorded prospectively of all consecutive patients who underwent robotically assisted catheter ablation therapy using the Sensei X robotic navigation system at the Christiaan Barnard Memorial Hospital, Cape Town, South Africa, from July 2009 to July 2010. Outcomes were defined at one and nine months.
Results : A total of 95 patients were included: 63% had only AF and 37% had AF plus atrial flutter. AF was of the persistent type in 81% of patients. The mean procedure, fluoroscopy and ablation times were 220.6 ± 89.6 min, 31.0 ± 20.4 min, and 61.3 ± 28.1 min, respectively. Both fluoroscopy and procedure times were significantly longer for the first 19 patients compared with the remaining 76 patients (43.5 ± 22.7 vs 27.8 ± 18.5 min and 274.7 ± 90.2 vs 207.1 ± 84.7 min, respectively, p = 0.002). The procedural endpoint of the study was successfully achieved in all patients. After one attempt, 27% were discharged from hospital off anti-arrhythmic drugs (AADs). At a median of nine months' follow up, 74% were AF-free off AADs, and 11% were AF-free on AADs, yielding a total freedom from AF of 84% without any redo procedures. Freedom from relapse after 1.12 procedures was 88%.
Conclusion : The Sensei X™ robotic navigation system offers a safe and effective approach for the treatment of AF. There was a learning curve with regard to fluoroscopy and procedure time, after which point reduction in radiation exposure and operator strain, as well as improvement in procedure throughputs were even more pronounced.

Abstract: There is sparse information on the epidemiology of effusive constrictive pericarditis (ECP). The objective of this article was to review and summarise the literature on the prevalence and outcome of ECP, and identify gaps for further research. The prevalence of ECP ranged from 2.4 to 14.8%, with a weighted average of 4.5% [95% confidence interval (CI) 2.2-7.5%]. Sixty-five per cent (95% CI: 43-82%) of patients required pericardiectomy regardless of the aetiology. The combined death rate across the studies was 22% (95% CI: 4-50%). The prevalence of ECP is low in nontuberculous pericarditis, while pericardiectomy rates are high and mortality is variable. In this review, of 10 patients identified with tuberculous ECP, only one presumed case had a definite diagnosis of ECP. Appropriate studies are needed to determine the epidemiology of ECP in tuberculous pericarditis, which is one of the leading causes of pericardial disease in the world.

Abstract: It was with interest that I read the article titled 'A systematic overview of prospective cohort studies of cardiovascular disease in sub-Saharan Africa' by André Pascal Kengne, et al., which was published recently in this journal. In this excellent article, the author introduced the association between cardiovascular diseases and related risk factors by performing a systematic review. However, we feel the article did not cover all aspects of the relationship between cardiovascular disease and related risk factors.

Abstract: Acetylsalicylic acid (aspirin) may have been around for over 100 years, but this 'cheap and cheerful' agent continues to surprise with new indications for its use. Prof Gordon McInnes feels that this 'old drug with new tricks' has an important ongoing role to play in both the primary and secondary prevention of cardiovascular disease (CVD). He was speaking at a meeting hosted by Bayer Healthcare in Johannesburg in May. 'Aspirin was developed in 1897 and is still going strong, with new indications for its use continuing to appear', he said.

Abstract: Severe haemoptysis due to infective subclavian arteritis has, to our knowledge, never been documented. We report a case of subclavian arterial vasculitis that eroded into the left lung apex, causing a large intraparenchymal mycotic pseudoaneurysm. The patient presented with high fever and blood expectoration. An emergent left lateral thoracotomy was performed. The inflamed segment of the subclavian artery was resected and continuity was restored with a reversed saphenous vein graft. The postoperative course was uneventful and the patient was discharged on the 10th postoperative day.

Abstract: Aneurysms of the left atrial appendage are extremely rare. Enlargement of the left atrial appendage can be congenital or acquired. Dysplasia of the left atrial muscles leads to congenital left atrial appendage aneurysm and usually presents as atrial tachyarrhythmia or embolic events in the second or third decade of life. We report a case of an asymptomatic 12-year-old child with a congenital left atrial appendage aneurysm. Transthoracic and transoesophageal echocardiography demonstrated a large left atrial appendage aneurysm without thrombus or spontaneous echo-contrast. The patient was successfully treated with surgical resection of the aneurysm.

Abstract: Dehiscence of a mitral annuloplasty ring is a rare occurrence. We present a young patient with long-standing gross dehiscence of a Duran annuloplasty ring secondary to suture dehiscence, occurring three years after mitral valve surgery. It was detected by transthoracic echocardiography. This case emphasises the importance of clinical and echocardiographic follow-up examinations after mitral valve surgery to detect any unexpected complications.

Abstract: We present here the fourth patient in the literature, over the age of 50 years old, with an abnormal right coronary artery arising from the pulmonary artery, who was successfully treated with surgery. Pre-operative computerised tomography (CT) angiography revealed an abnormal right coronary artery arising from the pulmonary artery. The right coronary artery was surgically transposed from the pulmonary artery to the ascending aorta with the aid of cardiopulmonary bypass. The patient had an uneventful postoperative course and the corrected anatomy was documented by postoperative CT angiography.
