AFRICA CARDIOVASCULAR JOURNAL OF AFRICA • SMC-PAFCIC Abstracts October 2022 56 Submission ID: 1683 SURGICAL OUTCOMES OF PATIENTS WITH SEVERE AORTIC REGURGITATION WITHIN MARKEDLY REDUCED LEFT VENTRICULAR FUNCTION: WHY SHOULD WE OPERATE ZINEB AGOUMY, SAMAH EL_MHADI, ZINEB FASSI FEHRI, HAMZA CHRAIBI, NESMA BENDAGHA, ADIL BENSOUDA, AIDA SOUFIANI, SAID MOUGHIL MOROCCO Background: Surgical management of patients with severe aortic regurgitation (AR) in the setting of significantly impaired left ventricle (LV) function generally carries very high operative risk. The aim of this study is to assess the short and long-term outcomes of aortic valve replacement (AVR) in a selected young Moroccan population. Therefore, optimistic results should encourage surgical approach for those patients. Patients and methods: Between January 2008 and June 2022, 127 patients in the Cardiovascular Surgery Department B of Rabat underwent AVR for massive isolated AR. This is a retrospective study that included all patients (overall 42 of 127 patients) operated for major AR with an ejection fraction ≤35%. Results: The average age was 44 years old with a male prevalence. Only two deaths are noted in immediate postoperative. At the 15 years follow-up, the survival in the 38 patients controlled is 86.8%. Clinical improvement was present in the majority of patients. The ventricular diameters have significantly decreased and the EF has increased by an average of 16%. Conclusions: In this case series, the patients benefited largely from AVR, as it has significantly improved their functional state as well as the LVEF in a majority of patients. The global operative mortality was acceptable (4.7%), due to the preponderance of young patients with rheumatic valve disease. The long-term survival (86.8%) better than described in the West. Key-words: Aortic regurgitation, left ventricular dysfunction, aortic valve replacement, prognosis, survival, long term. Submission ID: 1684 SPECTRUM OF CARDIOVASCULAR INVOLVEMENT IN BEHÇET DISEASE: NOT ONLY THROMBOSIS! EL-MHADI SAMAH, FASSI FEHRI ZINEB, AGOUMY ZINEB, EL HAJJAJ BELGHAIT, FELLAT NADIA, BENDAGHA NESMA, BENSOUDA ADIL, TAZI MEZALEK ZOUBIDA, SOUFIANI AIDA, FELLAT ROKYA MOROCCO Background: Behçet disease, also known as “Silk Road Disease”, is a chronic auto inflammatory disorder triggered by infectious and/or environmental factors in genetically predisposed individuals. It is characterized by a triple-symptom complex of recurrent oral ulcers, genital ulcers and uveitis. Despite the high incidence of vascular damage in Behçet disease, cardiac involvement is still uncommon. Cardiac imaging techniques such as Echocardiography, Computed Tomography Scan and Magnetic Resonant Imaging play an important role for both diagnosis and assessment of complications. Objective: The aim of our work is to report rare manifestations of cardiovascular Behçet disease and the place of multimodality noninvasive imaging in diagnosis, detection of complications and follow-up. Methods: Throughout a series of six real cases, we will emphasize heterogeneous cardiovascular manifestations of Behçet disease. Beyond intracardiac thrombosis, we will report uncommon cases of coronary artery involvement, left ventricular pseudo-aneurysm and endo myocardial fibrosis. Results: Our six patients were all male between the second and fourth decades of life, in whom Behcet disease was previously confirmed according to the International Criteria for Behçet Disease. Cardiovascular manifestations were non-specific, dominated by dyspnea, chest pain and fever. Even if intracardiac thrombosis is the most frequently reported lesion in literature, we herein report six various cardiovascular manifestations of Behçet disease, including: one case of classical right atrial thrombosis, two cases of right ventricular thrombosis associated to endo myocardial fibrosis, two cases of coronary artery involvement and one case of giant left ventricular pseudoaneurysm. Transthoracic echocardiography and cardiac MRI are two useful and noninvasive diagnostic tools that allowed us to detect all cardiac lesions and ensure good follow-up. Conclusion: Cardiac involvement in Behçet disease is uncommon but lifethreatening. A multidisciplinary approach can reduce morbidity mortality and rates. We suggest that echocardiography and other cardiac imaging techniques be routinely considered for early diagnosis and long-term follow-up. Submission ID: 1690 RELATIONSHIP BETWEEN CARDIOVASCULAR RISK AND NOCTURNAL SYSTOLIC-DIASTOLIC ARTERIAL PRESSURE IN HYPERTENSIVES AT CHU-IBN ROCHD. MAHOUNGOU MACKONIA NOEL MASCHELL, EL MOUSAID MERIEM, NASSOUR BRAHIM, HABOUB MERIEM, SALIM AROUS, BENOUNA GHALI, ABDENASSER DRIGHIL, LEILA AZZOUZI, RACHIDA HABBAL MOROCCO Introduction: Arterial hypertension is a real major public health problem in the world. Blood pressure (BP) has been shown to be associated with cardiovascular risk. However, clinical blood pressure measurement has several disadvantages, such as a limited number of blood pressure readings and the inability to assess blood pressure variability over a period of time. A nocturnal drop in blood pressure is a normal physiological regulation, called dipper-like blood pressure, and no drop in it is considered non-dipper; which was found to be significantly associated with adverse cardiovascular outcomes. The character of blood pressure dipper or not, their condition of variability in association with cardiovascular risk have not been sufficiently studied. Methods: We conducted a retrospective study on 35 patients with arterial hypertension for at least 2 years, in whom we performed an ambulatory blood pressure measurement and associated cardiovascular events, namely: coronary syndrome, stroke. Results: The average age of the patients was 64.5 ± 10 years, mainly men at 64% against 36% of women. The dipper trait was more important than the non-dipper at 56% versus 54%. The cardiovascular risk factors were objectified as follows: tobacco in 33% of cases, alcohol in 7% of cases, in 62% of cases the patients were diabetic, in 65% of cases they presented a metabolic syndrome and in 5 % of cases patients had coronary heredity. Arterial hypertension (HTA) associated with other risk factors was more frequent in the order MODERATED POSTER SESSION
