Ebstein’s anomaly is a rare congenital heart disease. We report a series of 4 cases of Ebstein’s anomaly discovered in adolescents. The mean age was 13.75 ± 0.96, with 3 boys and one girl. Three were in heart failure. The EKG showed atrial hypertrophy (1 case), right bundle branch block (1 case), Wolff-Parkinson-White (1 case), and atrial fibrillation (1 case). Cardiomegaly was present in all patients with a mean cardiothoracic index of 0.77 ± 0.03. On echocardiography, the mean apical displacement of the tricuspid septal leaflet was 22.5 ± 3.30 mm/m2, the Celermajer index was Grade 2 in 2 patients and Grade 4 in 2 patients. Depletive medical treatment was prescribed to 3 patients. Anticoagulant therapy was initiated in one patient. Two are awaiting surgery. One death was recorded, it was at Grade 4 of the Celermajer index.

The sub-mitral annular aneurysm is a rare cardiac pathology. The etiologies are diverse, ranging from the congenital form to the idiopathic form, including the acquired form. The clinical case we report is that of a 27-year-old young man, with no particular history, admitted with a picture of global heart failure. A cardiac ultrasound diagnosed a ruptured mitral sub-annular aneurysm in the pericardium. The difficulty lies in the surgical management of this condition, due to the lack of an adequate cardiac surgery service in most of the countries in Africa south of the Sahara.

Introduction: Hypertrophic cardiomyopathy (HCM) belongs to the very heterogeneous group of cardiomyopathies. This study aimed to study myocardial perfusion abnormalities on scintigraphy and assess the risk of sudden death from ventricular arrhythmia in hereditary sarcomeric HCM. Patients and Methods: This is a retrospective and prospective descriptive study over 18 months (January 01, 2021, to July 31, 2022) on the records of patients over 18 with the diagnosis of hypertrophic sarcomeric cardiomyopathy with or without ventricular rhythm disorders and who have undergone myocardial scintigraphy. Results: Three patients were included. The average age of our patients was 66 years old. Dyspnea is the primary symptomatology found in our patients. One patient presented with syncope and unsustained ventricular tachycardia. His risk score for sudden death from ESC at five years is estimated at 6.45%, and the patient received an ICD in primary prevention. The average sudden death risk score of our patients was 3.78%. The mean LV wall thickness was 20 mm. The mean maximum left intraventricular gradient was 39 mmHg. Myocardial fibrosis was present in all our patients. Myocardial scintigraphy was normal in all cases. Conclusion: Hypertrophic cardiomyopathy is a very heterogeneous group of cardiomyopathies. The rhythmic risk is multifactorial and constitutes a significant prognostic factor.

Introduction: High blood pressure is a real public health problem affecting more than one in three adults. The objective of this study was to evaluate the level of knowledge, attitudes and practices of health care personnel in the management of hypertension in Conakry. Methods: Descriptive transversal study of 6 months, from April 20, 2018 to September 20, 2018, which took place in the internal medicine departments of the two university hospital centers (CHU) of Conakry (Donka and Ignace Deen). The study population consisted of general practitioners and specialists, practicing in both departments for at least two years and who agreed to submit to our questionnaire. Results: At the end of the study, we included 140 doctors, 61% at Donka University Hospital and 39% at Ignace Deen University Hospital. The predominance was male with 113 men for 27 women with a sex ratio H/F = 4.18. General practitioners were the most represented with 95% against 5% specialists. Sixty-four percent of physicians gave an exact definition of hypertension, 56% of physicians confirmed the diagnosis of hypertension after 2 to 3 consultations. 19% offered monotherapy as first-line treatment, only 72% said that the duration of Antihypertensive treatment was for life. Conclusion: Theseresults demonstrate that it is essential to reflect on our daily practices for a good improvement in the quality of care for patients.

Introduction: Rheumatoid arthritis (RA) is the most common chronic inflammatory rheumatic disease. It is a systemic disease with extra-articular manifestations that can be life-threatening. In sub-Saharan Africa, there is little published information on cardiovascular manifestations in RA. Objective: The objective is to determine the asymptomatic cardiac manifestations during rheumatoid arthritis in Conakry. Patients and Methods: This was a cross-sectional study lasting 6 months from January 1, 2020 to June 30, 2020 in the rheumatology and cardiology departments of the Ignace Deen National Hospital. Patients with RA diagnosed according to the 2010 ACR/EULAR criteria, asymptomatic at the cardiovascular level, which had an ECG and echocardiography, were included in the study. Left ventricular diastolic dysfunction was considered in any patient with an E/A ratio 1, an E/E’ ratio > 10, and an LVEF = 50%, assessed by the Simpson biplane method and classified according to Redfield. Epidemiological, clinical and paraclinical data were analyzed using SPSS statistics 21.0 software. Results: Seventeen cases of rheumatoid arthritis (5.9%) were collected. There was a predominance of women with 14 cases (82.4%). The mean age of patients was 48.2 ± 11.9 years. The average duration of RA was 7.2 ± 4.2 years. Cardiovascular risk factors were dominated by overweight and obesity (58.8%) and sedentary lifestyle (35.3%). RA was predominantly high activity (DAS 28 ≥ 5.1) in 82.4% of patients. Anti-CCP antibodies were positive in 76.9% of cases. Fourteen patients (82.4%) had abnormal cardiac results. The electrocardiogram showed left atrial hypertrophy in 29.4% of cases, left ventricular hypertrophy (11.8%) and ventricular extrasystole (11.8%). The cardiac Doppler scan showed diastolic dysfunction of the left ventricle (47.1%) and moderate pericardial effusion in 11.8% of cases. Conclusion: The study found asymptomatic cardiac manifestations of rheumatoid arthritis. They were dominated b

Takayasu disease is a chronic vasculitis of the large vessels. It is rare in sub- Saharan Africa and probably under-diagnosed. Arterial hypertension (AH) is a frequent finding. We report the case of a 46-year-old man with Takayasu disease revealed by hypertension. The American College of Rheumatology (ACR) criteria were used for diagnosis, with 4 out of 6 criteria. Echodoppler and angioscanner showed signs of left subclavian stenosis and circumferential, regular arterial thickening. He had a biological inflammatory syndrome. He was treated with prednisone and amlodipine. After 6 months of follow-up, he was diagnosed with tuberculosis and put on anti-tuberculosis treatment.

Introduction: Obliterative arterial disease of the lower limbs is a marker of advanced atherosclerosis. It is one of the world’s most common cardiovascular diseases, present in one in five people over the age of 60, and carries an increased risk of morbidity and mortality. The aim of this study was to assess the knowledge of patients and their carers about obliterative arteriopathy of the lower limbs at Conakry University Hospital. Material and Methods: We conducted a descriptive cross-sectional study lasting 3 months, from March 12 to June 12, 2022 in the hospitals of the University Hospital of Conakry (Donka and Ignace Deen). Following free and informed consent, they were interviewed on the basis of a pre-established questionnaire. Socio-demographic data (age, gender, level of education) were collected, and knowledge of obliterative arterial disease of the lower limbs. Results: The study involved 159 people, comprising 106 patients (66.66%) and 53 accompanying persons (33.34%) in the hospitals of the University Hospital of Conakry (Donka and Ignace Deen). The 60 to 79 age group was the most represented (44.7%), with an average age of 55.4 ± 15.9 years and extremes of 20 to 84 years. Half (47.8%) had not attended school, and almost all (96.4%) of those who had attended school had a low level of education (primary and secondary). Almost all of them (91.2%) had never heard of AOMI. Only 5% identified at least one risk factor, diabetes, hypertension and smoking. Amputation was the most frequently identified complication. About 98% did not know that AOMI is associated with myocardial infarction and stroke, and 93.7% did not know of any complications. Almost all the participants (99.4%) had poor knowledge of the following complications. Conclusion: Obliterative arterial disease of the lower limbs could be prevented or delayed by screening and controlling risk factors. Our results show a huge deficit in knowledge of this pathology, including risk factors, preventive meas

Inter auricular communication (AIC) is the most common congenital heart disease after aortic bicuspid disease with an incidence of 5%?-?10% in children and 30%?-?40% in adults. It represents 6% to 10% of congenital heart defects with septal defect. Inter auricular communications (AIC) are the most common cardiac malformations in adults. This was a retrospective study of 5 cases of inter-auricular communication discovered in adulthood in the cardiology department of the Ignace Deen National Hospital between 01 November 2018 and 31 May 2019. The diagnosis was made by the Cardiac Doppler ultrasound. During the study period,?5 cases of AIC were registered at the cardiac department Ignace Deen. The average age of our patients was 51.8 years with extremes of 20 and 70 years. This average age is comparable to that of the literature that reports most develop symptoms after 40 years. In this study, male dominance was noted with 60% versus 40% of female cases. The evolution was marked by a death case of 20% who had AIC associated with an?inter ventricularcommunication (CIV) with signs of global heart failure and four cases had a favorable evolution or 80%.
