CARDIOVASCULAR JOURNAL OF AFRICA • SMC-PAFCIC Abstracts October 2022 25 AFRICA coronary aneurysm are diverse and dominated by atherosclerosis, it can also be caused in rare cases by vasculitis, autoimmune diseases (polyarteritis nodosa, systemic lupus erythematosus, scleroderma), trauma (including coronary angioplasty), coronary artery dissection, rheumatic, mycotic coronary emboli, syphilis. it is most often asymptomatic but in rare cases it may manifest itself as chest pain related to an acute coronary syndrome with or without ST-segment elevation. In this context, we report the case of a 66-year-old patient with active smoking (25YP) as a cardiovascular risk factor and no medical or surgical history. He was admitted to the emergency room for acute chest pain related to an ACS with ST-segment elevation, and coronary angiography revealed a giant aneurysm of the right coronary artery. Submission ID: 1441 LASER LEAD EXTRACTION EXPERIENCE: YES, WE CAN! HOUDA DAHMANI, MERYEM BENNANI, JAOUAD NGUADI, AMINE ALAOUI MALIKI, J. KHEYI, HICHAM BOUZELMAT, ALI CHAIB, AATIF BENYASS MOROCCO Background: Pacing and defibrillation leads may need to be removed for several reasons including infection, interference with others leads, lack of vascular access or redundancy. However, the removal of chronically implanted leads is a major technical challenge because of the extensive adhesions that develop along the course of the leads over time. The techniques to remove chronic leads have been greatly facilitated by the development of an excimer laser sheath. Figure 1: Laser lead extraction of the RV lead Figure 2: Representative lead extraction procedure. Objective: The purpose of this study is to evaluate the safety and efficiency of the Excimer laser sheath in extracting chronically implanted pacemaker leads. Methods and results: We undertook an analysis of the first moroccan experience with laser extraction in 11 patients from July 2013 to June 2021. A total of seventeen lead were removed completely. Infection was the most common indication. Lead age was 7,2 years. The mean time of procedure is 3 hours. There were no complications. Conclusion: The Excimer laser sheath appears to be an effective and safe technique for extracting chronically implanted pacemaker leads. It can be used in combination with the currently available techniques for successful lead extraction. Submission ID: 1444 EPIDEMIOLOGICAL STUDY OF INFECTIVE ENDOCARDITIS AT THE IBN ROCHD UNIVERSITY HOSPITAL IN CASABLANCA MAHOUNGOU MACKONIA NOEL MASCHELL, SALIM AROUS, BENOUNA GHALI, ABDENASSER DRIGHIL, LEILA AZZOUZI, RACHIDA HABBAL MOROCCO Introduction: Infective endocarditis is a serious and rare disease with a changing epidemiological profile over the years. Objective: To study the clinical, echographic, bacteriological, therapeutic and prognostic characteristics of patients in the cardiology department of the Chu Ibn Rochd of Casablanca. Material and method: We conducted a retrospective, cross-sectional study in the Chu-Ibn Rochd endocarditis database from 2021-2022. Results: We included 110 patients of whom 68 were men and 42 were women with a sex ratio of (M/F=1.6), predominantly young in 65.5%. Infectious endocarditis occurred: - in 90% on a native valve, including 8% of patients with known valvulopathy - in 8% on a prosthetic valve - in 1.8% on pacemaker equipment - in 6.3% on congenital heart disease. The most common portal of entry was a central line in 3.6% of cases, followed by skin and oral entry in 2.7%. MODERATED POSTER SESSION
