AFRICA CARDIOVASCULAR JOURNAL OF AFRICA • PAFCIC 2021 Abstracts December 2021 22 Submission ID: 1135 ACUTE COMPLICATIONS DURING CHRONIC TOTAL OCCLUSIONS REVASCULARIZATIONS Houssem BEN AYED, Aymen NOAMEN, Sarra CHENIK, Salma BEN MBAREK, Nadhem HAJLAOUI, Wafa FEHRI Military Hospital of Tunis, Tunisia Introduction: Chronic total occlusion (CTO) represents a real challenge to percutaneous coronary intervention (PCI) because of the technical difficulties, the risk of failure, complications and high rate of restenosis. Thus, the PCI in this case is discussed based on the result of the benefit and risk of the procedure. Aim of the study: To determine the in hospital complications of PCI for CTO within 72 hours after angioplasty. Patients and Methods: This is a descriptive retrospective single-center study including 62 patients who received 65 PCI for CTO from December 2010 to March 2017 at Military Hospital of Tunis. CTO was defined by a complete occlusion of coronary vessel with TIMI 0 flow greater than a three month. The PCI CTO procedural complications can be classified as follows: vascular access related and procedure related. Results: Our patients mean age was 55.1 years with a sex ratio of 2.64. Diabetes and smoking were the more prevalent cardiovascular risk factors. 94% of patients were symptomatic before angioplasty and acute myocardial infarction was the most common presenting feature. Mean left ventricular ejection function was 49%, with extremes ranging from 20 to 70%. The revascularization-success-rate was 76.8%. The complications were: One case of vascular access related complication: a hematoma of four centimeter of diameter at the puncture site., 7 cases of procedure-related complications, a case of aortic dissection sealed by direct stenting of the right coronary artery ostium, three cases of a small coronary dissection repaired by ad hoc stenting, two cases of dissection complicated by an immediate and transient re-occlusion treated with additional stenting without clinical consequences, one acute thrombosis of the left main artery which required thrombo-aspiration and Gp IIb/IIIa inhibitors In our study, we reported neither death, nor cardiogenic shock, tamponade or myocardial infarctionwithin 72 hours after angioplasty, nor the skin lesions associated with patient X-ray irradiation Conclusion: In the hands of experienced operators, CTO angioplasty is an interesting therapeutic option with a suitable rate of success and a low complication rate. Submission ID: 1152 CLINICAL AND PROGNOSTIC FEATURES OF INFECTIVE ENDOCARDITIS IN WOMEN Nesrine Amdouni, Ikram Chamtouri, Asma Ben Abdallah, Wajih Abdallah, Jomaa Walid, Khaldoun Ben Hamda, Faouzi Maatouk Cardiology B department of Fattouma bourguiba University Hospital, Tunisia Background: The influence of sex on the prevalence of certain valve diseases is already known. But we have little information about gender differences in patients with infective endocarditis (IE). Aim: To study the clinical characteristics and prognostic features of IE in women compared to those in men. Submission ID: 1155 ATRIAL SEPTAL DEFECT MANAGEMENT IN THE ERA OF PERCUTANEOUS CLOSURE DEVICES Gribaa Rym, kacem marwen, Ouannes Sami, Kaddour Hella, Mekki Nouha, Ben Farhat Sameh, Elheraiche Aymen, Slim Mehdi, Neffati Elies Tunisia Background: Atrial septal defects(ASD) are among the most common congenital heart disease encountered at all ages. Nowadays, transcatheter closure of septum secundum atrial defects is the mainstay of treatment for patients with suitable defects. Nevertheless, there are defects that are nonamenable to this strategy in which surgery should be the appropriate option for closure Aim: Study the results of surgical and percutaneous techniques of closure of atrial septal defect Material and method: We reviewed the clinical course of 190 patients who underwent closure of atrial septal defect at Cardiology department of Sahloul Hospital between 2000 and 2020.The patients were assigned to either the device or surgical group depending on what treatment they received. Results: In our population,71,1% were females. The mean age was 20.7 years with a minimum being 2 years old and a maximum being 69 years old. 14.2% had a history of repeated pulmonary infection. The most frequent symptom was exertional dyspnea which was present in 47.4% of all the patients. In the group who received percutaneous closure, the average size of the atrial septal defect was 21.1 mm with a minimum being 5 mm and a maximum being 39 mm.66.4% had moderate right ventricle dilatation while 29.4 % had severe right heart dilatation. The average of systolic pulmonary pressure was 36.9 mmHg before closure. The mostly used device was Amplatzer septal occluder in 70.4% of the patients in this group.10,7 % had a first temptation of percutaneous closure device but they had surgery at a second time. After a successful implantation, the average of peak systolic pulmonary pressure significantly decreased from 36,8 to 27,8(P<0.001). Major complications occurred in 7.2% and embolization of the prosthesis was the most frequent complication MODERATED POSTER SESSION 1 Methods and patients: This is a retrospective mono-center study including 245 patients collected in the cardiology B department of Fattouma Bourguiba University hospital between January 2000 and December 2019, hospitalized for IE. The diagnosis of IEwas made according to Duke’s criteria. Results: In our study, 106 patients were female (43.3%). The mean age was similar in both sexes (36 ± 18.6 years in women vs. 38.45 ± 17.2 years in men; p = 0.2). For IE of the left heart, mitral valve disease was significantly higher in women (35.8% vs. 25.9%; p = 0.042). Infective endocarditis of the right heart was similar in both sexes (9.5% in women vs. 7.2% in men; p = 0.13). The occurrence of IE on prosthesis was significantly lower in women (19.4% vs. 29.5%; p = 0.047). Analysis of two groups did not show a significant difference in the incidence of peripheral embolism (23.6% in women vs. 16.5% in men; p = 0.11) and in-hospital death (19% in women vs 18.7% in men; p = 0.53). Indication for valvular surgery was similar in both groups (33% in women vs. 29.5% in men; p = 0.23). Conclusion: This descriptive study concluded that there is a difference in the location of IE according to sex without consequences in any particular clinical or prognostic outcomes.
