[Coronarography and etiologies of heart failure with impaired left ventricular ejection fraction in Senegal].

Introduction: Heart failure is a major public health problem because of the number and duration of hospitalizations. Patients with heart failure may have mixed etiologies that are not mutually exclusive, and etiologies vary between high-income and developing countries. The aim of our work was to study the contribution of coronary angiography in the etiological investigation of heart failure with impaired LVEF in the cardiology department of HPD.

Rare Coronary Artery Anomaly: Single Coronary Artery from Distal Circumflex Detected by CT.

BACKGROUND A single coronary artery is a rare congenital anomaly of the coronary arteries distribution, with an incidence of only 0.03% in the general population undergoing coronary angiography. RCA arising from the distal circumflex artery is an extremely rare variety.

Cardiac pacing: indications, modalities, complications, and challenges (results of a multicenter cross-sectional study in four hospitals in Dakar, Senegal).

Introduction: cardiac pacing is the only lifesaving procedure which is effective for major cardiac conduction disorders. In sub-Saharan Africa, few pacemakers are implanted, compared to Western countries. This study aimed to describe the indications for cardiac pacing in four hospitals in Senegal, to evaluate its practical modalities, to identify pacemaker's complications and their predisposing factors and to evaluate the main challenges for cardiac pacing in Senegal.

[Atrial fibrillation at the Principal Hospital of Dakar, Senegal: outcomes and limits of management].

Objectives: The aim of the study was to determine the prevalence of AF in the cardiology department of the Hospital Principal of Dakar, then to evaluate the clinical, paraclinical, etiological and evolutionary profiles of AF and finally to identify the limits of its management in our context.

Patients And Methods: This was a retrospective, descriptive, analytical, mono-centric study carried out at Hospital Principal of Dakar from January 2019 to August 2021. Were included, all patients admitted for atrial fibrillation, or patients who presented an atrial fibrillation during hospitalization, confirmed by electrocardiogram or long-term electrocardiographic recording during the study period.

[Percutaneous coronary intervention in the management of acute coronary syndromes in Senegal : Challenges and results].

Introduction: Percutaneous coronary intervention (PCI) remains a major therapeutic tool in the management of acute coronary syndromes (ACS). However, it is not widely practiced in sub-Saharan Africa, particularly for the management of ACS. The availability of a catheterization laboratory for 24-hour management of ACS in Dakar is an important step in improving the prognosis of patients.
