CARDIOVASCULAR JOURNAL OF AFRICA • PAFCIC 2021 Abstracts December 2021 57 AFRICA (14%). It should be noted that 11% were explored as part of a general pre-anesthesia assessment. Resting electrocardiogram at admission was pathological in 84%of the cases. Echocardiography at admission revealed segmental kinetic disorders in 87% of cases, indicating the presence of ischemic cardiomyopathy. The average of the ejection fraction of the left ventricle was 44 ± 17%. Coronarography showed significant stenosis in 79% of cases, and for the rest, the coronary network was infiltrated as a whole. The most common pathological aspect was mono-truncular stenosis of the anterior interventricular artery (62%), left main coronary artery was affected in 8% of cases . Sixty-two percent of patients had coronary revascularization (angioplasty or aorto-coronary bypass surgery). Revascularization was correlated with better short- and long-term outcomes. Conclusion: Because of its diagnostic difficulty and lack of consensus on its treatment, SMI remains an important cause of cardiovascular morbi-mortality. It is good practice to consider the profile of at-risk patients and use screening in order to establish an early diagnosis and adopt appropriate therapeutic management: revascularization. Submission ID: 1084 TWO AND THREE-DIMENSIONAL ECHOTOMOGRAPHY OF THE LEFT ATRIAL Fares Araiez, Nour Cherif, Rym Hentati, Rym Ben Romdhane, Sofien Zayed, Kaouther Bachraoui, Rami Tlili, Youssef Ben Ameur Monji Slim Hospital, Tunisia Background: The left atrial is the elective site of formation of 90% of thrombi in non valvular atrial fibrillation. Its study by two-dimensional transesophageal echocardiography, the glod standard imaging method, faces several types of difficulties. The relatively recent advent of three-dimensional real-time mode has broadened the technical arsenal. Objectives of the work: To carry out a morphological and functional transesophageal echocardiographic study of the left atrium and its anatomical variants, and to clarify the contribution of the three-dimensional mode in real time in this study. Methods: We carried out a retrospective descriptive study on a population of 70 patients from the cardiology department of Mongi Slim hospital, who underwent transesophageal echocardiography in both twodimensional and three-dimensional modes in real time, regardless of the indication. We have identified the clinical and ultrasound characteristics relating to the morphology and activity of the left atrial as well as their implications in intraauricular thrombogenesis. Results: The mean volume of the left auricles analyzed was 3.83 ± 3.79 ml and the mean ejection fraction was 53%. Most of the left auricles had ellipsoid rather than circular ostia (mean eccentricity index: 1.26). Patients, who were in atrial fibrillation at the time of the ultrasound examination, had more dilated left atrias characterized by a lower ejection fraction and sawtooth pulsed Doppler flow with average filling and emptying velocities very low (36 cm/s and 35 cm/s respectively). In two-dimensional transesophageal echocardiography, we have shown that the dimensions of the left atrial can be deduced particularly from two views: 45° and 135°. In addition, the three-dimensional mode allowed us to study the auricle with more precision, to identify its different anatomical variants, to differentiate more easily the trabeculae from the thrombi and to calculate the ejection fraction by volume. Conclusion: Transesophageal echocardiography, through its two-dimensional and three-dimensional modes, allows a precise and reliable morpho-anatomical and functional study of the left atrium and thus provides valuable information for the understanding and prevention of thromboembolic events of cardiac origin. The recently introduced three-dimensional mode improves the diagnostic and therapeutic technical capabilities of echocardiography. Submission ID: 1085 THE TIME OF CONSULTATION COMPARED TO THE ONSET OF CHEST PAIN IN CASE OF STEMI IN WOMEN IN TUNISIA Fares Azaiez, Elyes Lagha, Rym Hentati, Rym Ben Romdhan, Sofien Zayed, Rami Tlili, Youssef Ben Ameur Monji Slim Hospital, Tunisia Background: Coronary artery disease remains the leading cause of death in women around the world. Current recommendations for ST Elevation Myocardial Infarction (STEMI) apply to both sexes, although women have been underrepresented in randomized clinical trials of primary angioplasty, with noted differences between the sexes in presentation, physiopathology and treatment of STEMI. The aim of this study is to investigate the consultation time of women in case of STEMI. Methods: This was a retrospective study of 111 patients collected within the cardiology department at the “Mongi Slim” university hospital in Tunisia, for a period of 3 years, between January 1, 2016 and January 31, 2019, hospitalized in the acute phase (within the first 24 hours) of an acute coronary syndrome with ST segment elevation and all treated with urgent primary angioplasty. Results: In our study, the mean time to consult compared to the onset of chest pain was 8 hours and 38 minutes with extremes ranging from 0 to 24 hours. According to this criterion, our population was divided into 4 groups (Figure 1): group1: Primary angioplasty in the first 3 hours: 23 patients (20.9%), group 2: primary angioplasty between 3 and 6 hours: 42 patients (38.2%), group 3: primary angioplasty between 6 and 12 hours: 31 patients (28.2%) and group 4: primary angioplasty between 12 and 24 hours: 14 patients (12.7%). In our study we noticed also that patients over 50 years consult earlier compared to those under 50 years old, 8.7% of patients under 50 years old consult before the third hour against 91.3% at the third hour in those over 50 years old. Conclusion: Myocardial infarction in women has a particular epidemiological profile and a reserved prognosis. as our study has shown, delay in consultation and age are two determining factors in the prognosis of female patients in case of STEMI. This may be because women underestimate their cardiovascular risk or misinterpret symptoms, which are considered atypical.
