ABSTRACT: Background: Coronary artery disease is increasing in Senegal as a result of epidemiological transition and the growing burden of cardiovascular risk factors. Since 2019, coronary artery bypass grafting (CABG) has been progressively structured within the local surgical team. Following the first Senegalese series reporting 10 cases performed between 2019 and 2022, surgical activity has significantly expanded between 2023 and 2025. Objective: To describe the current status, early outcomes, and development perspectives of CABG in Senegal based on an expanded institutional experience. Methods: This study is based on a combined analysis of historical series, recent operative records, and institutional registries, including a total of 55 patients who underwent CABG between 2019 and 2025. Results: A total of 55 CABG procedures were performed, providing for the first time a sufficient operative volume for robust epidemiological and technical analysis. The patient profile was dominated by advanced multivessel coronary artery disease, with triple-vessel involvement observed in approximately 65% - 70% of cases. Cardiovascular risk factors were highly prevalent, including hypertension (60% - 70%), diabetes (30% - 40%), dyslipidemia (≈30%), and smoking in nearly half of the patients. Left ventricular systolic function was generally preserved, with a mean ejection fraction ranging from 50% to 60%, although segmental wall motion abnormalities were present in 30% - 40% of cases. Surgically, the left internal mammary artery was used in more than 90% of procedures, associated or not with saphenous vein grafts. The recent period has been marked by the introduction of off-pump CABG, performed in 5 patients (9.1%), reflecting the initial adoption and progressive diversification of surgical techniques. Conclusion: CABG in Senegal has entered a phase of expansion and consolidation, with encouraging early results. This study provides a comprehensive national overview based on the integration of published data, prospective registry analysis, and recent operative experience. Continued development of surgical expertise, infrastructure, and access to care is essential to meet the growing burden of coronary artery disease in this setting.
