The new educational project Televascular Games during the Coronavirus Disease 2019 pandemic.

Objective: To report methodology and first-year results of a new educational project called Televascular Games," which took place during coronavirus disease 2019 pandemic. Methods: Complex aneurysmal aortic disease was discussed during a 2-hour competition webinar, according to three modalities. (1) Planning case competition (PCC): Two to four preoperative computed tomography angiography (CTA) scans of an already performed selected case were submitted for the competition. CTA scans were uploaded anonymously, without any reference to the center or the surgeon who performed the case. The competitor had to prepare a presentation of how he or she would have diagnosed, sized, planned, treated, and followed up the case, of the medical therapy and of the bail-out maneuvers. (2) Challenging case competition (CCC): The competitor elaborates a presentation of an already treated case concerning an aortic topic and discusses sizing, planning, treatment, possible bail-out maneuvers and obtained results. For the CCC and PCC, the competitors with the best score were preselected to present and discuss their plan during the webinars. (3) Quiz competition: Two to six CTA scans of already performed selected aortic cases were submitted for the competition. A quiz with multiple choice questions was answered by the competitors. The top four competitors were selected for the webinars and then they discussed the cases during the webinar. Finally, at the end of the case discussion, the effective case resolution and follow-up were shown. A final winner was voted via televoting, based on six preestablished criteria. The project was endorsed by different national and international societies. Results: Between October 2020 and December 2021, there were 12 Italian and 1 international webinars with 1695 participants overall (mean, 130; range, 86-177). Competitors were 54 years of age (mean, 27 years; range, 22-38 years). Two editions were CCCs, two quiz competitions, and nine PCCs. The reliability of the interobserver sizing of competitors was κ = 0.43 and κ = 0.62 for the proximal and distal sealing measurements respectively and very good (κ = 0.88-0.95) in the evaluation of orientation of the vessels, presence of angulations, calcifications, and thrombus. The sizing discrepancy resulted in a significant variability of the planning (κ = 0.45). The project ranked 9.6 on a 10-point rating scale by all the participants and competitors. Conclusions: The formula of gaming and collegial discussion of aortic cases herein reported has proved valid and attractive during coronavirus disease 2019 pandemic period. The variability of the results on sizing and planning suggested to confer with a second opinion, especially for less experienced surgeons.

THE IMPACT of SARS-COV-2 in VASCULAR SURGICAL ACTIVITY in A TERTIARY HOSPITAL

Introduction/Objectives: The Corona Virus Disease 0/2019 (COVID-19) has taken a major toll on the public health system, with restrictions in all clinical activity, from consultations and exams to number and type of surgeries. Patients apprehension to resort to medical aid and hospitals leads to late admissions and, in our perception, more severe presentations of the underlying pathology, namely, in Chronic limb threatening ischemia (CLTI). Need for testing prior to non-emergent surgery causes larger delays in the referral of patients, and this, added to the reduction of surgical times andlCU availability, potentially results in worse outcomes. The aim of this study was to objectively evaluate the type pathology that was treated during the emergency state and to compare the outcome of the surgical procedures with the same period of 2018 and 2019. Methods: A retrospective analysis of the patient charts from patients submitted to surgery in the months of March and April of the year 2020 was conducted and compared to the same period on the previous two years. The primary endpoint was death at 30 days or during hospital stay and the secondary endpoints were pathology classification, grade of ischemia, amputation, amputation level, type of surgery (endovascular, conventional or hybrid), time of hospital stay and reintervention. Results: There were 98 patients submitted to surgery in the COVID period (CP), compared to 286 in the Non-COVID period (NCP). There was no significant difference in the age (70 years (17-98) in the CP vs. 69 (17-92) in the NCP, p=.i3) or sex profile of the patients (76% male (n=74) in the CP vs. 70% (n=i96) in the NCP, p=.26). There was no statistical differ¬ence in mortality (5% (n=5) in the CP vs. 5% (n=i3) in the NCP, p=.88). There was a statistically significant decrease in conventional surgery (43% (n=u2) in the CP vs. 57% (n=i6 4) in the NCP, p=.04), but no statistically significant difference in length of hospital stay(io (0-77) days in the CP vs. 7 (0-118) in the NCP, p=.6), and reintervention (18% (n=i8) in the CP vs. 16% (n=45) in the NCP, p=.s8). PAD corresponded to 75% (n=73) of the admissions in the CP vs. 48% (n=i37) in the NCP, p=.02. CLTI corresponded to 99% (n=70) of the PAD population in the CP, vs. 93% (n=n 4) in the NCP, p=.i, with a significant increase in the number of patients presenting with Rutherford Grades 5 and 6 (81% (n=57) in the CP, vs. 68% (n=77) in the NCP, p=.03). There was a non-significant decrease in amputation rate (35% (n-25) vs. 40% (n=49J, P-49) and increase of major limb amputation (52% (0=13) vs. 39% (n=i9), p=.27). The second mostfrequent pathology was aneurysmal aortic and iliac disease, but there was a statistically significant reduction in the number of patients treated (5% (n=s) in the CP vs. 13% (n=36) in the NCP, p=.os). All aortic aneurysms treated in 2020 were ruptured (100% (n=s) vs. 42% (n=is) in the NCP, p=o.2). There was no significant difference in mortality in urgent aortic aneurysm repair between groups (60% (n=3) in the CP vs. 47% (n-7) in the NCP, p-.77). Conclusions: COVID-19 restrictions manifested mainly in the type of pathology treated and the number of patients operated on. The gravity of the underlying pathology, manifested by more serious wounds and advanced CLTI at presentation, did not increase mortality nor was reflected on limb amputations rates. Aortic and iliac aneurismal disease was the second most common pathologytreated but with a significant decrease in total number of cases and no significant difference in mortality.

Secondary prevention of rheumatic heart disease in ethiopia

Introduction: Acute rheumatic fever (ARF) and rheumatic heart disease (RHD) are significant causes of morbidity and mortality. Ethiopia has a high RHD prevalence but has no national strategic guidelines for preventing RHD and no data on the status of secondary prevention in children with RHD. Generating local information is essential to designing effective prevention and control strategies. This study describes the status of secondary RHD prevention in Ethiopian children. Methods: A multicenter, cross-sectional study was performed in children aged 5-17 years with an echocardiogram-based RHD diagnosis. Participants with congenital heart disease and a recent RHD diagnosis (<1 year) were excluded. Good adherence was defined as at least 80% completion of intramuscular benzathine penicillin (BPG) or oral Amoxicillin within the previous year. The primary outcome measure was adherence to prophylaxis, expressed as a proportion. Covariates included socio-demographics, type and severity of RHD, and ARF recurrence. Chi-square test and Student's t-test were used to assess differences. Multivariate logistic regression was performed. Results: We included 337 participants with a mean age (±standard deviation) of 12.9±2.6 years. The majority were females (54%) and 73% had severe aortic/mitral disease. BPG (80%) and Amoxicillin (20%) were the prophylaxis of choice. Predictors of good adherence were female sex (P=0.04), use of BPG (0.03), and shorter mean duration of prophylaxis in months (48.5±31.5 vs. 60.7±33, P<0.008). Running out of medicines (35%), interrupted follow-up (27%), and the COVID pandemic (26%) were the three most common reasons for missing prophylaxis. Recurrence of ARF was higher in participants on Amoxicillin (40% vs. 16%, P<0.001) and in those with poor adherence (36.8% vs. 17.9%, P=0.005). Type and duration of prophylaxis (OR 0.5, P=0.02;OR=1.1, P=0.04, respectively), and sex (OR=1.9, P=0.03) were independent predictors of poor adherence. Conclusion: Poor adherence is prevalent in Ethiopian children with RHD. Amoxicillin is a suboptimal option for prophylaxis associated with lower adherence and a higher rate of ARF recurrence.

Type A aortic syndromes in COVID-19 positive patients: Case series from a UK multicentre study.

OBJECTIVE: The coronavirus disease (COVID-19) increases the respiratory complications and carries a higher mortality in the immediate postoperative period. The aim of this study was to analyze the outcomes of patients with type A acute aortic syndromes (AAS) diagnosed with COVID-19 in the perioperative period. METHODS: Retrospective analysis of prospectively collected data between March and August 2020 from 20 participating cardiac surgery centers in the United Kingdom. RESULTS: Among 122 patients who underwent emergency surgical repair for type A AAS at the participating centers, 3 patients (2.5%) tested positive for COVID-19 in the preoperative screeing, and 4 cases turned to be positive in the postoperative period having been operated on an unknown COVID-19 status. Another patient was diagnosed of COVID-19 disease based on radiological features. These eight patients had increased postoperative complications, including respiratory failure, longer ventilation times, and Intensive Therapy Unit (ITU) stay and increased mortality when compared with COVID-19 negative patients. CONCLUSION: COVID-19 disease in the perioperative period of type A AAS poses a challenge. Despite the increasing morbidity and mortality associated with the virus, the prognosis of the aortic disease is poorer and emergency surgery should not be contraindicated based on the COVID-19 diagnosis alone.

Management of acute and chronic aortic disease during the COVID-19 pandemic-Results from a web-based ad hoc platform.

BACKGROUND: To share the results of a web-based expert panel discussion focusing on the management of acute and chronic aortic disease during the coronavirus (COVID-19) pandemic. METHODS: A web-based expert panel discussion on April 18, 2020, where eight experts were invited to share their experience with COVID-19 disease touching several aspects of aortic medicine. After each talk, specific questions were asked by the online audience, and results were immediately evaluated and shared with faculty and participants. RESULTS: As of April 18, 73.3% answered that more than 200 patients have been treated at their respective settings. Sixty-four percent were reported that their hospital was well prepared for the pandemic. In 57.7%, the percentage of infected healthcare professionals was below 5% whereas 19.2% reported the percentage to be between 10% and 20%. Sixty-seven percent reported the application of extracorporeal membrane oxygenation in less than 2% of COVID-19 patients whereas 11.8% reported application in 5%-10% of COVID-19 patients. Thirty percent of participants reported the occurrence of pulmonary embolism in COVID-19 patients. Three percent reported to have seen aortic ruptures in primarily elective patients having been postponed because of the anticipated need to provide sufficient ICU capacity because of the pandemic. Nearly 70% reported a decrease in acute aortic syndrome referrals since the start of the pandemic. CONCLUSION: The current COVID-19 pandemic has-besides the stoppage of elective referrals-also led to a decrease of referrals of acute aortic syndromes in many settings. The reluctance of patients seeking medical help seems to be a major driver. The number of patients, who have been postponed due to the provisioning of ICU resources but having experienced aortic rupture in the waiting period, is still low. Further, studies are needed to learn more about the influence that the COVID-19 pandemic has on the treatment of patients with acute and chronic aortic disease.
