ABSTRACT
INTRODUCTION: The reuse pacemakers is a beneficial technique for patients in countries with a low economic standard of living where health care is almost non-existent. We offered to share the experience of Senegal on the reconditioning of pacemakers. METHODOLOGY: We conducted a retrospective study over a period from January 2015 to December 2020 including all patients who benefited from a reconditioned pacemaker for primary implantation or reimplantation. The criteria for reconditioning pacemakers are the absence of dysfunction or damage and a residual battery life of more than 5 years of the pacemaker. Refurbished pacemakers are acquired either from deceased families or from extraction centers. Sterilization is carried out using phenoxypropanol + benzalkonium chloride solution, 70% ethanol and ethylene oxide. RESULTS: We collected 161 patients during the study period, including 77 men (48%) and 84 women (52%), i.e. a M/F sex ratio of 0.94. The average age of the population was 65 years. Functional symptomatology was dominated by syncope in 54%. Electrocardiographically, 72% of patients were in complete atrioventricular block. A primary implantation was noted in 91.5% of patients. The vascular approach most used during implantation was cephalic in 49.5% of cases. In our series, we noted that 58% of patients had benefited from temporary stimulation before implantation. At implantation, single-chamber stimulation was used in 60% of patients and 46.5% of patients had programming in VVI mode. We had 5.5% major complications with 3% box infection occurring between 3 and 6 months post-implantation and 2.5% pacemaker syndrome. We noted 1 case of death linked to underlying heart disease. CONCLUSION: Reconditioning of cardiac pacemakers is a safe and beneficial therapeutic strategy for patients. In Senegal, reconditioning has shown satisfactory results. In our countries this technique can be an alternative for certain patients.

INTRODUCTION: Acute circulatory failure is a life-threatening emergency whose prognosis depends on early management and aetiological diagnosis. The aim of our study was to assess the epidemiological, aetiological, therapeutic and prognostic aspects of acute circulatory failure in two cardiology departments in Dakar. METHODS: This was a longitudinal, multicentre, descriptive study over a period of six months from October 2014 to March 2015. We included all patients with acute circulatory failure (systolic blood pressure < 90 mmHg, oligoanuria, tachycardia, tachypnoea, onset of altered consciousness) either on admission or during hospitalisation during the study period. A long-term survival survey (six months to one year) was conducted on all included patients. RESULTS: Forty-four patients were enrolled. The average age was 54.9 years, ranging from 20 to 83 years. The gender ratio was 1.1. Acute circulatory failure occurred most often during hospitalisation (63%), with known cardiomyopathy in 47.7% of cases. Consciousness was impaired in 11 patients while oligoanuria was present in 27.3% of cases. Inflammatory syndrome was mostly found in 63.6% of cases and renal insufficiency and acute liver failure were reported in 45.5 and 29.5% of patients, respectively. Left ventricular dysfunction was the most common echocardiographic feature (70%). Acute circulatory failure was cardiogenic in most cases, with a predominance of advanced dilated cardiomyopathy (44.9%). Septic shock was found in 25% of patients, with pulmonary infection as the main location (20%). Nine per cent of patients had hypovolaemic shock. The most used inotropic drug was dobutamine in 79.5% of cases, followed by adrenaline (18.2%) and norepinephrine (4.5%). Intra-hospital mortality rate was high (52.3%) and one-year survival rate was 27.2%. Poor prognostic factors such as advanced age and renal impairment were associated with a higher overall mortality rate of 18 to 90%, with no statistical significance. CONCLUSIONS: Acute circulatory failure is a diagnostic and therapeutic emergency with a high mortality rate.

Hydatidosis, an anthropozoonosis caused by the development of the Echinococcus granulosus larva in human, is a parasitic infection that is endemic in many countries. Pericardial localization in the absence of other cardiac involvement is extremely rare. Its spontaneous evolution is serious because of the risk of rupture. We report the case of a 65-year-old patient, who received limb edema that had been going on for 4 months, and in whom the physical examination noted a 3/6 tricuspid regurgitation and a right heart failure syndrome. Transthoracic echocardiography revealed an intra-pericardial mass whose contents appeared fluid with hyperechogenic area. It measured 86x61 mm and significantly compressed the straight cavities. Thoracic computed tomography showed an appearance in favor of an aged intrapericardic hydatid cyst (GHARBI V) with mass effect on the right cavities. The hydatid serology was negative. The patient did not accept the surgical cure. She had been put on albendazole and diuretic treatment. Fatal outcome was reported after two-month follow-up.
La localisation péricardique d'Echinococcus granulosus en l'absence d'une autre atteinte cardiaque est extrêmement rare. Son évolution spontanée est grave du fait du risque de rupture du kyste hydatique. Nous rapportons le cas d'une patiente de 65 ans, reçue pour des ÅÅdèmes des membres inferieurs qui évoluaient depuis 4 mois. L'examen physique notait un souffle d'insuffisance tricuspide 3/6 et un syndrome d'insuffisance cardiaque droite. L'échocardiographie transthoracique a objectivé une masse intra-péricardique dont le contenu paraissait liquidien avec des plages hyperéchogènes. Elle mesurait 86x61 mm et comprimait de manière importante les cavités droites. La tomodensitométrie thoracique a conclu à un aspect en faveur d'un kyste hydatique (GHARBI V) intrapéricardique vieilli avec effet de masse sur les cavités droites. La sérologie hydatique était négative. La patiente n'a pas accepté la cure chirurgicale. Elle a été mise sous albendazole et traitement diurétique. L'évolution a été fatale après deux mois de suivi.

High blood pressure (HTA) is a public health problem. It affects more than one billion people around the world, more than a quarter of the world's population. In recent years the ABPM (Ambulatory Blood Pressure Measurement) has become a valuable and widely used tool for the diagnosis and management of hypertension. The aims of this study were to determine the indications of MAPA to the cardiology department of Aristide le Dantec Hospital; to determine the results and to evaluate the blood pressure profile of our patients. METHODS: We carried out a retrospective study, over 37 months from December 2010 to December 2013 covering all the results of the ABPMs recorded during this period. Was included any patient over 18 years of age with an ABPM. All ABPMs with less than 50 good measures per 24 hours were not included. RESULTS: A total of 204 MAPA results were included of a total of 307. The mean age was 49.6 ± 11.5 years with extremes of 25 years and 78 years. The sex ratio was 1.5 in favour of women. Indications were dominated by labile HTA (34.8%); masked HTA (27.9%) and suspicious of the white coat effect (12.3%). The analysis of the results showed that MAPA was normal in 49.5%. The white coat effect was found in 32% (65 patients) of ABPM. In patients with abnormal ABPM, permanent systolic-diastolic hypertension predominated (57%). HTA masked was noted in 25.7% of our patients and HTA white coat was found in 3.8% of cases. In the hypertensive patients treated, MAPA revealed a poor blood pressure balance in 42.1%. Among the HTA prognostic factors we noted32.4% of patients were "Non Dippers", a pulse pressure greater than or equal to 60 mmHg in 59%. CONCLUSION: The use of this exploration is an important aid to practitioners in the diagnostic, therapeutic and prognosis phase of the management of hypertension. It should become more important as it provides better information on the blood pressure profile for the patients.
INTRODUCTION: L'hypertension artérielle(HTA) représente un problème de santé publique. Elle concerne plus d'un milliard d'individus à travers le monde, soit plus du quart de la population mondiale. Ces dernières années la MAPA (mesure ambulatoire de la pression artérielle) est devenue un outil précieux et largement utilisé pour le diagnostic et la prise en charge de l'HTA. Les objectifs de ce travail étaient de déterminer les indications de la MAPA au service de cardiologie de l'hôpital Aristide le Dantec ; d'en déterminer les résultats et d'évaluer le profil tensionnel de nos patients. MÉTHODES: Nous avons réalisé une étude rétrospective, sur 37 mois allant de Décembre 2010 à Décembre 2013 portant sur l'ensemble des résultats des MAPA enregistrées durant cette période. Était inclus tout patient âgé de plus de 18 ans chez qui une MAPA a été enregistré Toutes les MAPA ayant moins de 50 bonnes mesures par 24 heures n'ont pas été inclus. RÉSULTATS: Au total 204 résultats de MAPA ont été inclus sur un total de 307. L'âge moyen était de 49,6 ± 11,5 ans avec des extrêmes de 25 ans et 78 ans. Le sex ratio était de 1,5 en faveur des femmes. Les indications étaient dominées par l'HTA labile (34,8%) ; l'HTA masquée (27,9%) et la recherche de l'effet blouse blanche (12,3%). L'analyse des résultats avait montré que la MAPA était normale dans 49,5% des cas. L'effet blouse blanche était retrouvé dans 32% (65 patients) des MAPA réalisées à visée diagnostique. Chez les patients dont les résultats étaient anormaux l'HTA systolo-diastolique permanente prédominait (57%) avec une différence significative (p=0,003). L'HTA masquée étaient notée chez 25,7% de nos patients et l'HTA blouse blanche était retrouvée dans 3,8% des cas. Chez les hypertendus traités, la MAPA avait révélé un mauvais équilibre tensionnel dans 42.1% des cas et cela au dépens de la systolique avec une différence significative (p=0,02). Parmi les facteurs pronostiques on retrouvait 32,4% de patients « Non Dippers ¼, une pression pulsée supérieure ou égale à 60 mm Hg dans 59%. Le caractère adrénergique était retrouvé chez 65,7% de nos patients. CONCLUSION: L'utilisation de cette exploration constitue une aide importante aux praticiens à la phase diagnostique, thérapeutique, et pronostique de la prise en charge de l'HTA. Elle devrait occuper de plus en plus de place car elle donne de meilleurs renseignements sur le profil tensionnel dans l'environnement quotidien habituel du patient.
ABSTRACT
BACKGROUND: Congenital heart diseases in adults include malformations treated in childhood that decompensate secondarily and those asymptomatic at birth, appear later. This study aims to identify congenital heart diseases in adults in general cardiology department of Senegal and to assess clinical presentations, treatment and outcomes. METHODS: We conducted a cross-sectional and descriptive study based on the records of patients aged at least 16 years and followed for congenital heart disease in the cardiology department of the General Hospital of Grand-Yoff in Dakar between May 2003 and March 2015. Diagnosis of heart disease was based on echocardiography. RESULTS: We have registered 50 dossiers of patients equivalent to a prevalence of 0.75%, with a female predominance (64%). The average age of patients was 36.2±18.4 years (16-79 years), and mean age of diagnosis was 29.76±22.58 years. Dyspnea was the main sign (60%). Main malformations were the atrial septal defect (38%), pulmonary stenosis (14%), the ventricular septal defect (12%) and patent ductus arteriosus (10%). According to the classification of Bethesda, heart disease was simple complexity (42%), intermediate (58%) or severe (10%). The treatment was medical in 43 patients and 7 patients had surgical repair. Main complications were infective endocarditis (10%), atrial fibrillation (12%), heart failure (24%) and pulmonary arterial hypertension (50%). CONCLUSION: Congenital heart diseases in adults seem underestimated in our countries. Surgical repair is rare. It is necessary to ensure a good management of the transition between pediatric and adult age.

The aim of this study was to compare the features of coronary artery disease between diabetic and non-diabetic patients. PATIENTS AND METHODS: A case-control study was carried out from 1 May 2013 to 31 July 2015 in the department of cardiology of Aristide le Dantec university hospital. Forty-five diabetic patients and forty-five non-diabetic patients who underwent coronary angiography and / or angioplasty were included. RESULTS: There was a male predominance with a sex ratio of 1.6 in both groups. The mean age was 62.26 years for diabetics and 59.06 years for non-diabetics (p = 0.6). In diabetics, symptomatology was dominated by silent ischemia (48.9%) versus typical angina pain (68.9%) in non-diabetics. Myocardial infarction was the most common indication of coronary angiography in both groups. Coronary angiography revealed one-vessel disease (46.6% versus 41.7% p = 0.822), double vessel disease (26.7% versus 41.7% p = 0.091) and triple vessel disease (26.7% versus 16.6% p = 0.561). Angioplasty was indicated in 37.8% of diabetics versus 63.9% of non-diabetics. Nine diabetic patients and three non-diabetic patients had an indication of coronary artery bypass grafting. CONCLUSION: Our study confirms the greater frequency of silent ischemia and multiple-vessel disease in diabetics as well as a more frequent indication of coronary artery bypass grafting in these patients.
L'objectif de cette étude était de comparer les aspects de la maladie coronaire entre les patients diabétiques et non diabétiques. PATIENTS ET MÉTHODES: Une étude cas-témoins a été réalisée du 1er mai 2013 au 31 juillet 2015 au service de cardiologie du CHU Aristide le Dantec. Quarante cinq patients diabétiques et 45 patients non diabétiques ayant bénéficié d'une coronarographie et/ou d'une angioplastie avaient été inclus. RÉSULTATS: Nous avions retrouvé une prédominance masculine avec un sex ratio de 1,6 dans les deux groupes. L'âge moyen était de 62,26 ans pour les diabétiques et de 59,06 ans pour les non diabétiques (p=0,6). Chez les diabétiques, la symptomatologie était dominée par l'ischémie silencieuse (48,9%) et la douleur angineuse typique (68,9%) chez les non diabétiques. L'infarctus du myocarde était l'indication de la coronarographie la plus fréquente dans les deux groupes. La coronarographie retrouvait respectivement chez les diabétiques et non diabétiques une atteinte mono-tronculaire (46,6% versus 41,7% p=0,822), une atteinte bi-tronculaire (26,7% versus 41,7% p=0,091) et une atteinte tri-tronculaire (26.7% versus 16,6 % p=0,561). Une angioplastie avait été indiquée chez (37,8%) des diabétiques et (63,9%) des non diabétiques. Neuf patients diabétiques et trois patients non diabétiques avaient eu une indication de pontage coronaire. CONCLUSION: Notre étude confirme une plus grande fréquence de l'ischémie silencieuse et de l'atteinte multi tronculaire chez les diabétiques ainsi qu'une indication plus fréquente de pontage aorto coronaire.
ABSTRACT
Systemic lupus erythematosus is a non-specific inflammatory disorder of an organ of unknown cause and autoimmune origin. Visceral injuries, including those cardiovascular, determine the prognosis of this disease primarily affecting women. The objectives of this study were to determine the frequency and describe the cardiovascular manifestations in systemic lupus erythematosus in a lupus population of the Dakar region. This is a multicenter prospective study descriptive and analytical conducted in the region of Dakar (Senegal) from 14 February 2011 to 2 July 2012. Patients were either hospitalized or monitored as outpatients. Included were all patients with lupus and meeting at least four criteria of the American College of Rheumatology of lupus disease classification 1997. All patients underwent physical examination, an electrocardiogram and an echocardiogram looking for cardiovascular damage. The collected data were entered into the Epi Info version 3.5.1 and processed with SPSS 16.0 software. Quantitative variables are described in the median and the qualitative workforce, percentage and frequency. We have included 50 patients. The average age of the population was 36.18 years. A female predominance is noted with a sex ratio man/woman of 0.09. Cardiovascular functional symptoms were dominated by dyspnea stage II to IV NYHA (26%) and palpitations (22%). The physical signs we have found were mainly tachycardia (40%), spontaneous turgor of the jugular veins (29%), a muffling of the heart sounds (29%) and a infandibulopulmonairy shock (18%). The frequency of cardiovascular events was 46%. Electrical cardiac events were dominated by sinus tachycardia (40%) of repolarization disorders (16.3%) type of ischemia, injury, ischemia injury, necrosis and hypertrophy with 18% atrial and left ventricular hypertrophy each. Furthermore, one case of BAV first degree at 280 ms was recorded. We found 19 cases of pericarditis including 2 tamponade, 3 cases of dilated cardiomyopathy hyperkinesias with impaired ejection fraction less than 35% and 8 patients with mild PAH important. In systemic lupus erythematosus, cardiovascular events are worrying and may remain asymptomatic for awhile. Their research must be systematic in order to treat early.

Congenital heart diseases are one of the major cardiovascular diseases in developing countries. Most prevalence studies were based on clinical examination of children with echocardiographic confirmation of suspected cases and underestimate its prevalence. The objective of this study was to investigate the prevalence of congenital heart disease in "daara" (Koranic schools) in the city of Dakar and its suburbs on the basis of clinical examination and Doppler echocardiography in school children. This cross-sectional survey was carried out from 9(th) August to 24(th) December 2011, and included a population of 2019 school children aged 5 to 18 years in 16 selected "daaras" under the Academic Inspectorate of Dakar and its suburbs. Anamnestic, clinical and echocardiographic data were recorded in a validated questionnaire. A p < 0.05 was considered to be statistically significant in bivariate analysis. 2 019 school children were included out of which 60.1% were male (sex-ratio: 0.66). The average age was 9.7 years (± 3.3 years). 18 cases of congenital heart diseases were detected being a prevalence of 8.9 per 1 000 (95 % CI: 1.8 to 7.9). This included 6 cases of inter-atrial septal aneurysm, 5 cases of peri-membranous ventricular septal defects, 4 cases of patent ductusarteriosus and 3 cases of tetralogy of Fallot. Factors correlated with the presence of congenital heart disease were ageless than 8 (p <0.001) and residence in the suburbs of Dakar (p <0.001). We also detected 10 cases of rheumatic valvular disease, a prevalence of 4.9 per 1 000 (95% CI: 2.4 to 9.1). Our study shows a high prevalence of congenital heart diseases, which is almost identical to the WHO estimates and that ultrasound screening is more sensitive than clinical screening. Reducing the prevalence of these diseases requires implementation of appropriate policies, focusing on awareness and early detection.
