0380: Study of anatomical features of pulmonary veins assessed by computed tomography according to age
IntroductionPulmonary veins (PV) play a crucial role in triggering and generating atrial fibrillation (AF). Isolation of PVs is fundamental in the AF ablation whether paroxysmal or persistent. The presence of four distinct pulmonary veins (two left PVs and two right PVs) has been described as the normal variant.AimThe purpose of our study was to investigate whether the age of the patients had an influence on the incidence of anatomical abnormalities of PVs.MethodsOur study was a prospective study which has included 38 patients followed for AF in the cardiology’s department of our hospital. All patients underwent a CT scan of PVs in order to characterize their anatomy. PVs’ size was represented by the largest diameter. We have divided our cohort into two groups: group 1: patients aged more than 50 years and group 2: patients aged less than 50 years.ResultsOur patients had a mean age of 50.5±13 years. The majority of our patients had paroxysmal AF (65%), 4 had persistent AF (10%), 9 had prolonged persistent AF (25%).CT Scan of PV results according to age are summarized in table.ConclusionIn our study, we found no significant relationship between age and anatomical abnormalities of the PVs. Hence, it is important to look for these anatomical anomalies whatever was the age of the patients to increase the success rate and to avoid complications during the AF ablation procedures.Abstratct 0380 – Table: Comparison of PV features evaluated by CT scan according to ageGroup 1 Age>50 years old N=20 patientsGroup 2 Age≤50 years old N=18 patientsPThe average left atrium volume140.8±75.78ml75.72±29.10mLP=0.01Mean number of PV3.85±0.484±0.65NSAverage diameter of left PV26.82±8.6825.03±12.29NSAverage diameter of right PV20.58±5.3522.81±6.05NSLeft single ostium forming a core collector4 (20%)3 (16.6%)NSRight single ostium forming a core collector1 (5%)4 (22%)N
The Effectiveness of Governmental Policy Measures on Controlling the Spread of Covid-19: Empirical Evidence from Around the World
The rapid spread of COVID-19 in China and the world dramatically affected the development in China and many countries worldwide. Different governments applied various policy measures to control the virus and prevent its spreading inside their countries. These policy measures combined with this global health crisis have serious consequences on the health system in different countries and the world economy. This thesis aims to quantitatively measure the effectiveness of the governmental policy measures that are taken during the risk management of the coronavirus across different countries on controlling the spread of the virus. Also, this thesis highlights the different policies implemented to control the COVID-19 virus in 48 countries which represent a quarter of the member countries in the United Nations. I chose 8 countries from each region that implemented different preventive policy measures to control the COVID-19 virus. This thesis provides empirical evidence for the effectiveness of each policy using quantitative analysis known as time serious analysis. To achieve this objective, we use both quantitative and qualitative data to evaluate the effectiveness of governmental policy measures to combat COVID-19 in different countries. This data was analysed using both descriptive analysis and regression analysis to correlate the various policy measures and their impacts on the spreading of the virus. R software was used to produce different graphs to show the descriptive analysis, while STATA software was used to show the quantitative analysis. This study used the random-effect model to analyze the quantitative panel data. The results show that lockdown, curfew, airport shutdown, banning public transportation, closing places of worships, compulsory quarantines for travelers, random community testing, the use of the modern health technology were effective in identifying and controlling the spread of COVID-19 virus. We prove that most of the governments’ implemented policies were effective in controlling the spread of the COVID-19 virus
Using of Virtual Reality Techniques in Education to Achieve Physical and Intangible Heritage for Historical Buildings
The main objective of the research is to use the virtual reality to serve the heritage environment and to build a complete and correct mental image of the architectural heritage through virtual reality techniques as a mechanism of documentation, preservation and utilization of virtual reality techniques in the educational process of students in university education and schools, preservation of heritage, The importance of heritage buildings and the value of values and raise the awareness of the community and benefit from them economically. It was therefore necessary to use virtual reality to help preserve the historical heritage and community awareness through the use of the descriptive approach in the theoretical part where the reality is identified and explain the importance and how to use it when reviving the heritage buildings and study the methods used to implement the analytical and applied method through the presentation of models This technique was used when reviving its heritage building

0222: The information provided by the monitoring of recovery during a treadmill test
IntroductionThe diagnosis of myocardial ischemia on exercise testing (ET) is typically based on ST segment during exercise and its recovery. However, according to recent studies attention should be paid on exercise capacity but also the heart rate profile, particularly its recovery in the first minute with a diagnostic and especially prognostic value. The importance of these variables is more pronounced in women posing positive diagnostic problem in the ET.MethodsThis study included 350 women with type 2 diabetes (TD2), with mean age of 58.84 years. It consisted of practicing a maximum treadmill test (TT) according to the Bruce protocol.ResultsAfter a positive TT, coronary angiography was proposed to135 cases. The results are in favor of a truly positive TT in 35 patients (25.62%), in 33.51% it is infiltrations and in 40.31% coronaries appear healthy. Univariate analyses according to the variables of the TT, the ones who have a statistically significant positive correlation, are: HRR 1’ (p=0.008), the reservation of HR (HR max – HR rest) (p=0.02), and recovery time of ST depression (p=0.006). Multivariate analysis in confrontation with coronary angiography, those among others predicts significant coronary lesions: -amplitude ST segment (p=107 5) and its recovery time (p=0.08) -the HRC 1 ’(p=0.02), the global recovery time (p=0.02). The prediction performance of coronary anomaly is 87.88%.ConclusionWomen in the interpretation of ST shift can lead to misinterpretation and necessitate the study of parameters which include those in recovery. This work by using exercise testing may therefore allow stratification of coronary risk and especially to avoid the practice of coronary angiography after weakly positive effort
