CARDIOVASCULAR JOURNAL OF AFRICA • PAFCIC 2021 Abstracts December 2021 37 AFRICA MODERATED POSTER SESSION 3 Submission ID: 1030 PREVALENCE OF ARRHYTHMIAS AND CONDUCTION DISTURBANCES POST-TAVR SARRA CHENIK, Amira Talhaoui, Aymen Noomen, Taha Yassine Jabloun, Abdeddayem Haggui, Nadhem Hajlaoui, Wafa Fehri Cardiology department, Military Hospital of Tunis, Tunisia Introduction: Percutaneous or transcatheter aortic valve replacement (TAVR) represents a real revolution in the treatment of symptomatic patients with severe calcified aortic stenosis (ACR) at high risk or having a contraindication for surgery. However, cardiac conduction disturbances and arrythmias remain a frequent complication of TAVR. Methods and objective: This is a retrospective single-center study describing the prevalence of arrhythmias and conduction complications for the 51 patients who underwent TAVR with a balloon-expandable valve and selfexpanding valve conducted in the military hospital of Tunis between November 2013 and February 2020. Results: The average age was 78.88 ± 8 years with a sex ratio of 1.21 for the entire workforce. In our population, 27 patients presented arrhythmias and conduction disturbances after TAVR implantation. For arrhythmias, four percent of the population developed atrial fibrillation and two percent developed ventricular tachycardia. In terms of conductive disorders, we noted the occurrence of right bundle branch block in four patients, left bundle branch block in five patients and left anterior hemi block in two patients. Four patients developed a high degree conductive disorder and only one patient required pacemaker implantation. Conclusion: The appearance or increase of conductive disorders is a common complication after TAVR. However, the development of pre, per and post procedural planning strategies and the availability of new devices have made it possible to prevent them and quickly manage these complications. Submission ID: 1036 PREDICTORS OF SMOKING CESSATION AFTER ACUTE CORONARY SYNDROME Sarra Chenik, Sabrine Soudani, Sana Said, Taha Yassine Jabloun, Nadhem Hajlaoui, Wafa Fehri Cardiology department, Military Hospital of Tunis, Tunisia Background: Smoking is a major risk factor for coronary heart disease. Indeed, smoking cessation is recommended after an ACS. After a first infarction, the life expectancy of smokers is significantly reduced compared to that of non-smokers. The aim of this study was to identify the main predictive factors for smoking cessation after ACS. Methods: This study was retrospective and included 244 patients who had been hospitalized for ACS in the cardiology department of the main military training hospital in Tunis. Results: This study included 244 patients. The mean age was 62 years with a male predominance (sex ratio 1.65). 44.9% of the patients were considered a big smoker. We were able to achieve smoking cessation in 83%. According to the results of the sub-analysis, smoking cessation six months after an acute coronary syndrome had a statistically significant effect on the duration of hospitalization in the cardiology department (p=0.01), on the occurrence of major cardiovascular events (p=0.02) and on one-year mortality (p=0.05). Conclusion: Behavioral risk factor accompanied by a strong dependence, which often makes its management difficult. Better control of this factor would allow, in primary prevention, to avoid the earliest and most unfair cardiovascular events, and in secondary prevention, to reduce major cardiovascular events. Submission ID: 1069 MORTALITY AFTER 6 MONTHS OF FOLLOW UP OF AN ALGERIAN POPULATION PRESENTING WITH ACUTE HEART FAILURE Djermane Dalila, Djouhri Messaouda, Haddad Assia, Ouldbessi Nadia, Saidouamer Dalila, Salim Benkhedda Mustapha Bacha A2 cardiology, Algeria Background Prevalence of heart failure patients (HF) is increasing worldwide due to the aging of the population and improvement in managing coronary artery disease and hypertension, which remain the main etiologies. The prognosis of this pathology remains bad especially in acute heart failure with represents its worse feature. Objectives and method A monocentric prospective study enrolling consenting patients over 18 years old admitted presenting with acute heart failure from January 2018 to September 2019 is performed in order to determine their prognosis and epidemiologic profile with a follow up of 6 moths. The primary endpoint is all causes death. Results 221 patients are enrolled. Mean age is 63 years old. Sex ratio is 1.63. Hypertension (59%) is the main cardiovascular risk factor, 45% are diabetics and 16% unveiled active smokers. Ischemic etiology (34%) is the most common followed by hypertensive heart disease (19.5%), cardiomyopathies (13%), and valvular heart disease (12%). Acute coronary syndromes (18.6%) and infections (18.1) are the main precipitating factors. “De novo” type is more common (68%) than chronic decompensated HF (33%) and the global forms are predominant (53.4%). The 6 months mortality is 41 % using the Kaplan Meier method. Prognostic factors were a high level of NTProBNP and liver transaminases and dilation of inferior vena cava. Conclusion Despite all the efforts made to improve the outcome of HF syndroms, AHF remains a challenge. New therapeutics in this field have shown a lowering in the incidence of death and rehospitalitions . A better knowledge of HF should bring other answers to many issues met in our daily practice.
