Bland-White-Garland syndrome or ALCAPA is an abnormality of birth of the left coronary artery from the pulmonary artery. It is a diagnostic and therapeutic emergency because it is a curable cause of hypokinetic dilated heart disease in infants. We report through this clinical case, the fourth case of infantile ALCAPA diagnosed in Senegal in a 7-month-old infant. The symptomatology began around the age of 2 months, with a grumpy state associated with more marked crying and moaning during feedings and bowel movements. The mother reported hospitalization for a severe lung infection when she was 6 months old. The examination noted an infant in poor general condition, retarded growth and weight, and a 3/6th holosystolic murmur at the apex. Troponinemia was positive at 43.90 ng/L. The electrocardiogram showed Q waves on the lower side, a sub endocardial lesion on the upper side and a ST segment elevation in aVR. Doppler echocardiography showed dilated cardiomyopathy with a mean alteration of systolic function of the left ventricle at 37%, a mean mitral insufficiency and a strong suspicion of a birth anomaly of the left coronary artery. The CT scan confirmed the diagnosis of ALCAPA. Surgicalreimplantation of the left coronary artery at the aortic level was performed at 10 months of life with a favourable outcome at D50 postoperative.

INTRODUCTION: Mitral valve abnormalities in hypertrophic cardiomyopathy (HCM) are becoming increasingly well defined, and their role in intra-ventricular obstruction is well defined. The aim of this study was to evaluate mitral valve abnormalities in patients with HCM. PATIENTS AND METHODS: We conducted a descriptive cross-sectional study from May 1 to July 1, 2022 in the Cardiology Department of Aristide Le Dantec Hospital. All patients with HCM aged at least 18 years old were included. The parameters studied concerned mainly the mitral valvular apparatus (papillary muscles abnormalities, leaflet length, mitral insufficiency). RESULTS: A total of 10 patients were included. Mean age was 58.3. On Doppler echocardiography, mean interventricular septal thickness was 20.6 mm. The mean maximum intra-ventricular gradient was 21.06 mmHg. Two patients had significant intraventricular obstruction. The mean length of the anterior mitral valve leaflet was 28.7 ± 3.55 mm, with extremes of 22 and 33 mm. The posterior mitral leaflet averaged 14.8 ± 3.16 mm. Nine (9) out of 10 patients had an elongated anterior valve leaflet. Elongation of the posterior leaflet was noted in 6 patients. With regard to papillary muscle position, 6 patients had an anterolateral ascending pillary muscle. These patients had a mean intra-ventricular gradient of 25 mmHg, compared with 16.5 mmHg in the others cases. We found no direct insertion on the mitral valve. Mitral insufficiency was noted in 9 patients, including 5 with mild insufficiency and 4 with moderate one. CONCLUSION: Mitral valve abnormalities in HCM appear to be frequent. They should be analyzed for a better diagnostic and therapeutic approach.

Background: Ischaemic heart disease is the cause of 7.4 million deaths per year. Their prevention is based on the management of cardiovascular risk factors, but also on the early detection and management of chronic coronary syndromes (CCS), for which few data are available in Africa. The main objective of our study was to determine the factors related to significative coronary artery disease in patients undergoing coronarography for suspected chronic coronary syndrome (CCS). Methodology: We conducted a retrospective descriptive and analytical study over 2 years (from January, 1st, 2018 to December 31st, 2019) in the Cardiology Department of the University Hospital Aristide Le DANTEC in Dakar. All patients admitted for coronary angiography for suspected chronic coronary syndrome were included. Results: One hundred and fifty-two patients were included with a mean age of 60.79 ± 9.73 years, the most represented age group was 60 - 69 years. Advanced age was the most frequent risk factor (77.63%) followed by sedentary lifestyle (56.58%) and hypertension (41.45%). Diabetes was present in 17.1% of cases. A history of angioplasty was found in 1.97% of patients. Typical pain was found in 71.05% of cases, atypical pain in 19.74% and exertional dyspnoea in 2.63%. The pre-test probability was intermediate in 67.1% of cases, low in 25% and high in 7.9%. Significative coronary lesion was found in 52.63% of the patients, while coronary angiography was normal in the remaining cases. Tritroncular status was observed in 37.50%, it was bitroncular in 26.25% and monotroncular in 36.25% of cases. Factors associated with significative coronary artery disease were age (p = 0.0001), diabetes (p = 0.006), previous angioplasty (p = 0.023), previous myocardial infarction (p = 0.018), typical angina (p = 0.001), intermediate pretest probability (p = 0.001). Low pretest probability was significantly correlated with the absence of a coronary lesion with a p = 0.001. Conclus

Introduction: The purpose of cardiac rehabilitation is to improve the effects of aging and maintain a good quality of life for older individuals. This study aims to assess how cardiac rehabilitation affects the autonomy and quality of life of older adults. Patients and Method: This was a longitudinal, descriptive and comparative before-and-after cardiovascular rehabilitation study conducted over a two-year period from January 2019 to December 2021. This study was conducted at four cardiac rehabilitation units in Dakar: the Aristide Le Dantec Hospital (HALD), National Dalal Jamm Hospital, and the General Idrissa Pouye Hospital (HOGIP). We compared the degree of autonomy, dependence and quality of life of subjects aged over 65 before and after the cardiac rehabilitation program using the Katz index, the Lowton index and the SF12 quality-of-life questionnaire. Results: Over a two-year period, a total of 345 patients had benefited from a complete cardiovascular rehabilitation program in the four cardiovascular rehabilitation units in Dakar, and 86 patients, or 24.92% of the population, were at least 65 years old. The patients were predominantly male (sex ratio M/F = 4.73). The mean age was 70.35 ± 4.55 years for men and 69.27 ± 4.59 years for women. The main pathology motivating cardiac rehabilitation was ischemic heart disease, which was found in 73 patients (84.88%). Initial assessment revealed exertional dyspnea in 35 patients (40.69%), followed by residual exertional angina in 21 patients (4.41%). Mean functional capacity increased from 5.81 ± 2.38 Mets in pre-cardiac rehabilitation to 8.68 ± 2.28 Mets in post-cardiac rehabilitation (p < 0.001). The mean distance covered in the 6-minute walk test increased from 330.42 ± 170.50 m in pre-cardiac rehabilitation to 524 ± 98.54 m in post-cardiac rehabilitation (p = 0.119). The Lowton dependency index in pre-cardiac rehabilitation was 44.18% versus 36.04% in post-cardiac rehabilitation (p = 0.0156). The mental quality of

Introduction: The improvement of survival in patients with cancer and the expansion of therapeutic options have led to the emergence of a new profile of cardiotoxicity, specifically associated with antimitotic agents. our study aimed to assess the incidence of chemotherapy-induced myocardial toxicity in patients with cancer. Patients and Methods: We conducted a looking-forward longitudinal cohort study including all patients admitted to the Cardiology departments of Aristide le Dantec Hospital and Dalal Jamm National Hospital Centre for apre-chemotherapy check-up. The included patients did not undergo any pre-existing cardiopathy. Results: Over a period of two years ranging from January 2019 to December 2021, a total of 37 patients were included in the study. Notably, there was a female predominance (92%) with an average age of 49.7 years ± 13.69. Breast cancer accounted for 70% of the neoplasms. Laboratory findings revealed moderate anemia in 19 patients (51%). At inclusion, the left ventricle (LV) was of normal size (LV diastole at 44.46 ± 4.97 mm). The systolic function of the left ventricle was normal in all patients, with an average ejection fraction (EF) of 63.1% ± 5.80 and a mean global longitudinal strain (GLS) of −20.4% ± 2.58. The most commonly used agents were anthracyclines. During follow-up, 3 patients (8.1%) developed clinical symptoms of left heart failure, and LV dysfunction on echocardiography was observed in 5 (13.5%) patients, with a significant decrease in EF Conclusion: The incidence of cardiac toxicity is not negligible, hence the importance of early screening. Strain imaging is an essential tool that should be performed as part of the assessment before chemotherapy and re-evaluated during treatment.
