Spanish Society of Cardiovascular & Endovascular Surgery registry of interventions in patients with congenital heart disease: 2021, and retrospective of the previous decade

The Spanish Society of Cardiovascular & Endovascular Surgery presents the 2012-2021 report of the activity in congenital cardiovascular surgery, based on a voluntary and anonymous registration involving most of Spanish centres. This article is complementary to the 2021 cardiovascular surgery annual report, and they are published together. In 2021, still marked by the aftermath of the COVID-19 pandemic, the decline in our 2020 congenital activity persists, compared with previous years. We included data from the previous 10 years, in order to obtain real information related to our activity with these relatively scarce pathologies. In the last decade, a total of 20,139 congenital heart surgeries were performed, accounting for 9.5% of all major surgery (congenital + acquired) performed in Spain during that period. Of these surgeries, 81.5% of them required extracorporeal circulation and 18.5% not. We highlight the interventions in neonates and adult patients, which mean respectively 18% and 21% of our whole activity and are a real challenge. The most prevalent congenital heart pathologies operated on were: septal defects in cases requiring extracorporeal circulation, and ductus in patients without extracorporeal circulation. The presented data are adjusted to the basic Aristotle score of preoperative surgical risk. The observed mortality of surgeries with extracorporeal circulation was 3.07% (Aristotle: 6.29), and without cardiopulmonary bypass 2.25% (Aristotle: 4.82). Our national registry of surgical activity in congenital heart disease shows good results, allows us to compare ourselves within a national and international framework, design improvement strategies, set objectives and improve the quality of our actions.Copyright © 2023 Sociedad Espanola de Cirugia Cardiovascular y Endovascular

The Effect of the COVID- 19 Outbreak on Intensive Care in Northern Saitama, Japan

Background: The 2020 COVID- 19 pandemic had various effects on local healthcare. The aim of this study was to assess the extent to which local healthcare and healthcare workers were affected by the COVID- 19 pandemic. Method(s): In this observational study we examined and compared intensive care units (ICUs) before (2019) and during (2020) the COVID- 19 pandemic to assess its effects. Emergency patient data were obtained from the Saitama Prefecture Emergency Medical Information System. The effect of COVID- 19 on emergency care responses was compared with the admission and refusal of patients in 2019 and 2020. We also examined the number of patients who were admitted to ICUs and required surgery. The effect on ICUs was examined with the number of Nurses' incident reports and severity percentages calculated from the integrated team medical care and safety system. We also compared the overtime hours of physicians on the basis of employment records. Result(s): In 2019, 2,136 emergency requests were made to admit patients, and 1,811 patients (85%) were admitted. In contrast, in 2020, 2,371 emergency requests were made, and 1,822 patients (76%) were admitted, representing a decrease to 76% (p = 0.931). The percentage of patients for whom admission was refused was significantly greater in 2020 (506 patients, 21.3%) than in 2019 (303 patients, 14.1%;p = 0.0004). In 2020, the number of neurosurgical, cardiac, and vascular operations increased and, over time, the number of operations increased for all surgical units. The number of incidents reported in ICUs increased significantly from 396 in 2019 to 510 in 2020 (p = 0.001). Conclusion(s): Although intensive care management was restricted, the numbers of patients and physician overtime hours were greater during the COVID- 19 pandemic than before, and the resulting environment led to an increase in the number of incidents. The ICU environments must be proactively improved to prepare for more severe situations in the future.Copyright © 2022 Jikei University School of Medicine. All rights reserved.

How to Maintain a Cardiac Surgery Service Amidst a Global Pandemic?

Objectives: 1) What is the SARS-CoV-2 virus?2) How has the COVID-19 pandemic affected cardiac surgery globally?3) How did a leading cardiac surgery centre in England cope and endure the pandemic?4) What suggestions have been looked into for future planning and service protection? Methods: In this report, the tangible effect withstood by this cardiac surgery service was assessed by analysing data collected in the fashion of an audit from four different time points: Pre-COVID, England's 1st Peak, England's 2nd Peak and the Present Day. Parameters included: total surgeries conducted, cancellations, cancellations due to a shortage of cardiothoracic critical care unit (CTCCU) beds and weekly averages for the aforementioned. Result(s): Results showed a significant drop in surgical output during the first peak (79.6% decreased output from Pre-COVID) and a large increase in cancellations both generally (from 25.1% to 28.2%) and due to CTCCU bed shortage (from 36.2% to 45.5%). However, a strong comeback was seen during the second peak (47.8% decreased output from Pre- COVID and 2.4% fewer cancellations), and an almost complete optimisation of service was observed in the Present day (45.1% increased output from Pre-COVID and 8.9% fewer cancellations). Conclusion(s): This trust's cardiac surgery service has adapted immensely;this audit has reported the list of measures taken to achieve this and the recommendations to achieve future surgical optimisation. The Trust managed to optimise its service and outperformed itself both from Pre- COVID and internationally. With further refining using PLECS and Canadian Society of Cardiac Surgeons guidance, full optimisation is feasible.

Minimally Invasive Coronary Artery Revascularization During Current Pandemics, New Hope! - Our Experience in a Third World Country

Objective: Since the last decade, the notion of minimally invasive cardiac surgery (MICS) has gained worldwide rapid popularity. Bangladesh is not far from mastering this technique due to the increasing interest of both patients and surgeons. Meanwhile, during this COVID-19 era could it help patients, remains the main question. In this context, we have operated on a total of 523 patients from October 2020 to November 2021 including, 89 patients who were MICS and among them, 17 were coronary artery bypass grafting. Method(s): We have included all patients who underwent minimally invasive coronary artery surgery in our hospital from October 2020 to November 2021 irrespective of single (MIDCAB) / multi-vessel disease (MICAS) or combined valve replacement with coronary revascularization. Data were collected from the hospital database, telephone conversations, and direct clinic visits. All data were analyzed statistically and expressed in the form of tables. Result(s): In the last 14 months of pandemics we have operated on a total of 89 MICS patients, among them 10 were Minimally Invasive Direct Coronary Artery Bypass (MIDCAB), 6 were double or triple vessels coronary artery surgery (MICAS), 1 patient underwent upper-mini aortic valve replacement along with coronary revascularization. One of our patients needed re-exploration for chest wall bleeding on the same day. Mean ICU and hospital stay in our series were less than conventional revascularization. There was no in-hospital or 30 days' mortality in our series. Conclusion(s): Cardiac surgery these days is headed toward less invasive approaches with the aid of technology, advanced instruments, and pioneer's lead. But from our in-hospital results we conclude that by avoiding median sternotomy, these minimal invasive revascularization techniques can provide hope to the patients by alleviating symptoms with restored vascularity, reduced morbidity, preventing sudden cardiac death. Health costs reduction with shorter hospital and ICU stay are the added benefits.

Epidemiological and pathogenetic mechanisms of atrial fibrillation depending on concomitant pathology, coronary bypass grafting and post-new coronavirus infection

Postoperative atrial fibrillation (POAF) is a common complication of cardiac surgery, including coronary artery bypass grafting, which has great clinical and economic importance for the healthcare system. Despite the improvement of surgical tactics, anesthetic and care benefits, POAF incidence has been increasing over the past decade. The mechanisms of POAF are different. Chronic coronary artery disease and its frequent comorbidities such as arterial hypertension, obesity, diabetes mellitus and heart failure, - are associated with various structural and functional changes in the heart, contributing to electrical atrial remodeling. Today, such risk factors for POAF as age, enlarged left atrium, post heart valve surgery, and obesity are well known. A new coronovirus infection that occurred in the early postoperative period can also be a trigger for atrial fibrillation. Postoperative arrhythmias can worsen both hospital and long-term results of treatment, increase the length of the patient's stay in the hospital, and the risk of complications. This review updates the data on the pathogenesis, incidence and complications of POAF, taking into account the current epidemiological situation.Copyright © 2022 Authors. All rights reserved.

Venovenous extracorporeal membrane oxygenation and late ductal stenting for infant with transposition of the great arteries, pulmonary stenosis and SARS, -CoV-2 pneumonia

Introduction: The SARS-CoV-2 pandemic has affected medical decision-making in all practice areas, including the pediatric cardiac intensive care unit (CICU), sometimes necessitating the use of innovative management strategies. Venovenous extracorporeal membrane oxygenation (VV-ECMO) and, particularly, late ductal stenting are infrequently applied interventions in the CICU. Here we present a critically ill infant with d-transposition of the great arteries (d-TGA), ventricular septal defect (VSD), pulmonary stenosis (PS), and patent ductus arteriosus (PDA), in which VV-ECMO and late ductal stenting were utilized successfully in the setting of active SARS-CoV-2 infection to treat worsening PS and pulmonary venous desaturation, thereby delaying surgical intervention and its associated risks during active infection. Case Description: A 3 month old male with d-TGA, VSD, and PS, initially managed with a balloon atrial septostomy at birth, was admitted to the CICU after presenting with respiratory distress and hypoxemia. He was found to be SARS-CoV-2 positive, requiring only nasal cannula initially. Admission echocardiogram demonstrated known d-TGA, VSD, severe pulmonary stenosis (peak gradient 95-110mmHg), unrestrictive atrial communication, and preserved systolic function. A tiny, hemodynamically insignificant PDA was also noted. While admitted, the patient exhibited intermittent, severe desaturations requiring escalating respiratory support. He was started on a prostaglandin infusion with aim to promote additional pulmonary blood flow through the PDA, thereby limiting the severity and frequency of desaturations. However, the patient ultimately became severely hypoxemic, despite multiple interventions to improve oxygenation. Echocardiogram at this time demonstrated preserved ventricular function, so the decision was made to escalate to VVECMO therapy. Following ECMO cannulation, the patient's hypoxemia quickly resolved, and he remained hemodynamically stable. Given the persistence of his PDA and the desire to avoid the risks of cardiac surgery in the setting of acute COVID infection, percutaneous intervention to augment pulmonary blood flow was attempted. Despite its diminutive size, his PDA was able to be successfully cannulated and stented the day after ECMO initiation. He was able to be quickly weaned from ECMO support and was decannulated the following day. He was subsequently extubated and ultimately discharged home with planning for definitive surgical intervention underway. Discussion(s): Here we present an interesting case of an infant with d-TGA, VSD, PS, and PDA in which VV-ECMO and PDA stenting were successfully applied to treat acute hypoxemia in the setting of SARS-CoV-2 infection and severe pulmonary stenosis. These therapies may be considered in appropriate patients for whom the risks of cardiac surgery are significant.

Incidental findings arising from targeted lung health checks: a GP practice perspective

Introduction: Newcastle Gateshead is a phase one Targeted Lung Health Checks site. Walker Medical Group GP practice serves a deprived population and is a designated Deep End practice. We report on the experience of Targeted Lung Health Checks at this practice. Method(s): Invitations were sent to eligible participants registered at the practice. Lung health checks were carried out by telephone according to Standard Protocol in the context of the COVID 19 pandemic. Those meeting criteria for Low Dose CT were invited to a mobile scanner located in the community near to the practice. Scans were reported according to the Standard Protocol. Result(s): Of 1481 eligible patients, 736 (50.44%) attended a telephone lung health check. 458 (63.6%) met criteria for a CT scan, of whom 33 declined a scan and 2 were unable to lie flat. 11 lung cancers (2.6%) and one other cancer were diagnosed. 71 (16.8%) had nodules requiring follow-up. These cases were managed by the TLHC programme and lung cancer MDT. Incidental findings had the greatest impact on general practice. 72.3% of scans showed coronary artery calcification. Of these, over 1 in 4 was not currently prescribed a Statin. New diagnoses of bronchiectasis (8 patients = 2%) and interstitial lung disease (7 patients = 1.6%) required GP action. 5 new cases of undiagnosed thoracic aortic aneurysm were identified, requiring referral for further action (1%). Conclusion(s): Incidental findings of Targeted Lung Health Checks CT scans require substantial input from a GP team. Coronary artery calcification is numerically most significant. Participants and practices should be supported by information and resources. Thoracic aortic aneurysm cases are also found in significant numbers and TLHC projects are advised to work with cardiology and cardiac surgery units when setting up. We plan to explore the reasons for participant refusal of CT scanning. Disclosure: No significant relationships.Copyright © 2023 Elsevier B.V.

Copper Deficiency Mimicking Myelodysplastic Syndrome: Zinc Supplementation in the Setting of COVID-19

While copper deficiency is rare, it can have serious consequences, including pancytopenia and neuropathy. This treatable micronutrient deficiency can present very similarly to myelodysplastic syndrome (MDS), a group of myeloid neoplasms which can carry devastating prognoses. Copper deficiency is an essential differential diagnosis in suspected MDS, as it can present with similar laboratory findings, bone marrow biopsy, and clinical picture. While copper deficiency has multiple potential causes, it typically occurs in patients with a predisposing gastrointestinal pathology. One possible cause of copper deficiency is zinc overload. Interestingly, zinc over-supplementation has been prevalent during the COVID-19 pandemic, as some believe that zinc can help prevent COVID-19 infection. Multiple case reports have illustrated the similarities between copper deficiency and MDS. They have also highlighted zinc over-supplementation as a potential cause. The following case report is unique in that our patient lacked gastrointestinal pathology. He still presented with the clinical and laboratory findings of MDS in the setting of copper deficiency. These include anemia, leukopenia, fatigue, and neuropathy. Further, this deficiency was caused by zinc over-supplementation in efforts to prevent COVID-19. The deficiency and the accompanying symptoms were treated with copper supplementation and cessation of zinc intake.

Year 2022 in review - Cardiac anesthesia and postoperative care.

Cardiac anesthesia and postoperative care in cardiac surgery have their specifics, which differ from other specialties. The last two years marked by the COVID-19 pandemic were associated with a slowdown in elective cardiac surgery. Currently, the number of procedures is increasing again. New drugs are tested, new guidelines are published, innovative and hybrid procedures are performed, with the goal of reducing invasiveness for the patients. The aim of this review is to present readers with the important outputs of publications related to cardiac anesthesia, postoperative care in cardiac surgery, and the use of extracorporeal circulatory support over the past year.Copyright © 2022, Czech Medical Association J.E.

Cardiac surgery during the COVID-19 pandemic.

The COVID-19 pandemic had several specific as well as general implications on cardiac surgery. Acute respiratory distress made extracorporeal oxygenation necessary in a significant number of patients and accordingly many patients were treated in anesthesiological and even more in cardiac surgical intensive care units, which left only a limited number of beds in the intensive care units available for elective surgery cases. Moreover, the necessary availability of intensive care beds for severely diseased COVID-19 patients in general posed a further limit, as did the relevant number of diseased personnel. Specific emergency plans were developed for many heart surgery units, limiting the number of elective cases. Increasing waiting lists were of course stressful for numerous elective-surgery patients and the decreased number of heart operations also meant a financial burden for many units.

Cold Agglutinin Detected in the Intraoperative Period: A Case of Coronary Bypass.

Cold agglutinin disease(CAD) is an autoimmune disease that occurs against erythrocyte antigens. It is usually idiopathic, but some infections can also be a trigger. CAD becomes active in the peripheral circulation at lower temperatures more easily when exposed to cold, causing hemolysis or agglutination. In this article, the management of a coronary bypass case with CA formation in intraoperative period is presented. A 46-year-old diabetic and hypertensive male patient had COVID-19 2 months ago. Cardiopulmonary bypass(CPB) was initiated with adequate heparinization, and the patient was cooled to 32degreeC. It was noticed that there were clots in the cardioplegia delivery line(+1degreeC). Agglutinations were observed in the autologous blood of the patient whose ACT values were normal. After CPB, the operation was completed without any problems and the patient was discharged on the 5th day with recovery. A diagnosis of CAD was made with the results of peripheral smear and immunologic tests. Determination of antibody concentration and thermal amplitude in the preoperative period in patients with CAD is very important. While preparing such patients for surgery, heating of room, patient, fluids, planning of normothermic CPB, and using warm cardioplegia are required. The relationship between CAD and COVID has started to take place in the literature. The patient we presented had a COVID 2 months ago, cold agglutinin may have been induced by COVID or may have arisen idiopathic. Considering that many people may have had a COVID nowadays, care should be taken especially in the perioperative period of cardiac surgery.Copyright © Telif hakki 2022 Gogus-Kalp-Damar Anestezi ve Yogun Bakim Dernegi Dergisi - Available online at www.gkdaybd.org.

Cardiac rehabilitation results among patients who have undergone cardiac surgery after covid-19 infection

Background: Coronavirus disease 2019 (Covid-19) has become a global pandemic. Covid-19 increases morbidity in patients with underlying cardiovascular disease. The six-minute walk test (6MWT) is a simple test for assessing cardiopulmonary fitness and has been applied to assess post-surgical recovery in cardiac populations. Decreased heart rate recovery (HRR) over 1 or 2 minutes after exercise shows autonomic dysfunction and is associated with an increased risk of mortality. We conducted a cross sectional study to determine if Covid-19 affects cardiac rehabilitation parameters, such as 6MWT distance, HRR-1, and HRR-2 among patients who have undergone cardiac surgery. Method(s): This analysis included 155 adults who had elective cardiac surgery at the National Heart Center Harapan Kita (NHCHK) from January to June 2022. Each participant performed a 6MWT and treadmill evaluation in phase II cardiac rehabilitation (CR) program. To analyze the association of 6mwt distances and heart rate recovery among patients with covid-19 and without covid-19 who had undergone elective cardiac surgery using Mann Whitney and Chi-Square tests. Result(s): Forty-Seven (30.3%) patients had a history of Covid-19. The mean 6MWT was 339.53 +/- 59.90 m in the pre-CR program, increased to 415.37 +/- 46.46 m in the post-CR program. The mean HRR1 was 15.16 +/- 9.44, and HRR2 was 56.59+/- 35.47. There were no differences in 6MWT distance, HRR1, and HRR2 among patients with a history of Covid-19 and without a history of Covid-19 (P= 0.48, p=0.56, p=0.12). Conclusion(s): The cardiac rehabilitation (CR) program improves the 6MWT distance. Covid-19 does not affect the ability of patients to do six-minute walk tests;neither HRR-1 nor HRR-2 among patients who have undergone cardiac surgery.

The SWISS PCI Survey - coronary and structural heart interventions in Switzerland 2020

For almost 35 years, the Swissworking Group for interventional Cardiology of the Swiss Society of Cardiology has evaluated and assessed the invasive diagnostic and therapeutic heart interventions performed annually in Switzerland.the aim of this survey, which was completed by 36 centres using a standardised questionnaire, was to report the data for the year 2020. Overall, 53,088 coronary angiographies with 48.8% subsequent percutaneous coronary interventions, i.e., 8.6% less than in 2019, were performed. regarding structural interventions, there were 1790 transcatheter aortic valve implantations, with a decrease of 6.4% compared with 2019.this decrease was most likely due to the coronavirus disease (COvid-19) pandemic and its consequences on the Swiss healthcare system.Copyright © 2021 Edizioni Minerva Medica.

Forging clinical collaborations and cooperation in overcoming challenges for non-COVID-19 patients during COVID-19 times: Surgical case studies requiring a multidisciplinary and inter-agency approach in Malaysia

The COVID-19 pandemic has brought global health services to a standstill. National healthcare systems and medical staffing in many countries have reached crisis levels due to the phenomenal outbreak. Healthcare resources have been strained to meet the unprecedented numbers of patient admissions with a significant amount of funding and manpower being channelled towards tackling this global pandemic. Despite the rollout of vaccinations, the development of new viral strains has now presented a new challenge. With the inevitable conversion of tertiary public hospitals to specialized COVID-19 centres with 'Full Covid Status' and the mobilization of its doctors from all specialities to care for these patients, the non-COVID-19 patients are becoming more neglected. The lack of elective surgeries performed and non-emergent admissions due to the unavailability of beds and personnel to care for this group of patients are concerning. As most of the focus and resources are now aimed at COVID-19 patients, the need to forge collaborations and cooperation between hospitals, agencies and healthcare systems are pertinent to ensure the provision of quality treatment for those suffering from non-COVID-19 diseases. To highlight this effort in Malaysia, we would like to present 2 case studies of non-COVID-19 patients undergoing elective surgeries through intergovernmental ministerial collaborations and a public-private partnership.Copyright © The Author(s) 2022.

Impact of Type of Enteral Feeds on Early Postoperative Outcomes After Congenital Heart Surgery in Neonates and Young Infants: A Single Center Experience in a Limited Resource Environment.

Background: Breast milk is known to prevent infections and is recommended for enteral feeding of infants after congenital heart surgery (CHS). During the Covid-19 pandemic, expressed breast milk (EBM) was not always available; hence, feeding after CHS was maintained with EBM or infant formula (IF) or both; we evaluated the impact of enteral feed type on early postoperative outcomes after CHS. Methods: In a prospective observational study, consecutive neonates and infants <4 months undergoing CHS were divided into EBM, IF, or EBM+IF groups; incidences of postoperative infections, ventilation duration, intensive care unit (ICU) stay, and mortality were studied. Results: Among 270 patients; 90 (33.3%) received EBM, 89 (32.9%) received IF, and 91 (33.7%) received EBM+IF. IF group had more neonates (78.7%[IF] vs 42.2%[EBM] and 52.7%[EBM+IF], P < 0.001) and greater surgical complexity. Postoperative infections were 9 (10.0%) in EBM; 23 (25.8%) in IF; and 14 (15.4%) in EBM+IF (P = .016). IF group (OR 2.58 [1.05-6.38], P = .040), absence of preoperative feeding (OR 6.97 [1.06-45.97], P = .040), and increase in cardiopulmonary bypass time (OR 1.005 [1.001-1.010], P = .027) were associated with postoperative infection. Ventilation duration in hours was 26 (18-47.5) in EBM; 47 (28-54.5) in IF; and 40 (17.5-67) in EBM+IF (P = .004). ICU stay in days was 4 (3-7) in EBM; 6 (5-9) in IF; and 5 (3-9) in EBM+IF (P = .001). Mortality did not differ (P = .556). Conclusion: IF group had a greater proportion of neonates with higher surgical complexity. Patients who received EBM after CHS had fewer postoperative infections and better postoperative outcomes compared to those receiving IF or EBM+IF.
