Cardiac surgery in patients with confirmed COVID-19 infection: Early experience

The novel coronavirus, now termed SARS-CoV-2, has caused a significant global impact in the space of 4 months. Almost all elective cardiac surgical operations have been postponed in order to reduce transmission and to allocate resources adequately. Urgent and emergency cardiac surgery is still taking place during the pandemic. The decision to operate in urgent patients with active/recent COVID-19 infection is difficult to make, particularly as it is still an unknown disease entity in the setting of emergent cardiac surgery. We present a case series of three patients who underwent urgent cardiac surgery and who have had recent or active COVID-19 infection.     

Eating behaviors and weight outcomes in bariatric surgery patients amidst COVID-19

BackgroundRecent studies suggest that eating habits are an area particularly affected by the lockdown imposed by many countries to curb the COVID-19 epidemic. Individuals that received bariatric surgery may represent a particularly susceptible population to the adverse effects of lockdown for its potential impact on eating, psychological, and weight loss outcomes.ObjectivesThis study seeks to investigate the incremental impact of COVID-19 lockdown on treatment outcomes of postbariatric patients in the risk period for weight regain.SettingMain hospital center.MethodsThis work uses data from an ongoing longitudinal study of bariatric patients assessed before surgery (T₀), 1.5 years after sugery (T₁), and 3 years after surgery (T₂). Two independent groups were compared: the COVID-19_Group (n = 35) where T₀ and T₁ assessments were conducted before the pandemic started and T₂ assessment was conducted at the end of the mandatory COVID-19 lockdown; and the NonCOVID-19_Group (n = 66), covering patients who completed T₀, T₁, and T₂ assessments before the epidemic began. Assessment included self-report measures for disordered eating, negative urgency, depression, anxiety, stress, and weight outcomes.ResultsGeneral linear models for repeated measures showed that the COVID-19_Group presented significantly higher weight concern (F = 8.403, P = .005, ?²_p = .094), grazing behavior (F = 7.166, P = .009, ?²_p = .076), and negative urgency (F = 4.522, P = .036, ?²_p = .05) than the NonCOVID-19_Group. The COVID-19_Group also showed less total weight loss (F = 4.029, P = .05, ?²_p = .04) and larger weight regain at T₂, with more COVID-19_Group participants experiencing excessive weight regain (20% versus 4.5%).ConclusionThese results show evidence for the impact of the coronavirus outbreak on eating-related psychopathology and weight outcomes in postbariatric surgery patients.     

Cardiac surgery considerations and lessons learned during the COVID-19 pandemic

The COVID-19 pandemic has transformed cardiac surgical practices. Limitations in intensive care resources and personal protective equipment have required many practices throughout the globe to pause elective operations and now slowly resume operations. However, much of cardiac surgery is not elective and patients continue to require surgery on an urgent or emergent basis during the pandemic. This continued need for providing surgical services has introduced several unique considerations ranging from how to prioritize surgery, how to ensure safety for cardiac surgical teams, and how best to resume elective operations to ensure the safety of patients. Additionally, the COVID-19 pandemic has required a careful analysis of how best to carry out heart transplantation, extra-corporeal membrane oxygenation, and congenital heart surgery. In this review, we present the many areas of multidisciplinary consideration, and the lessons learned that have allowed us to carry out cardiac surgery with excellence during the COVID-19 pandemic. As various states experience plateaus, declines, and rises in COVID-19 cases, these considerations are particularly important for cardiac surgical programs throughout the globe.     

The impact of COVID-19 on the provision of cardiac surgical services

The global pandemic caused by COVID-19 has had a significant global impact on healthcare systems. One implication of this pandemic is the cancellation of elective cardiac surgeries and the centralization of services. As a result, hospitals in Europe, North America, and the United Kingdom have had to alter the services offered to patients to be able to cope with service provision for COVID infected patients. Data should be collected during this period to provide a good insight following the lockdown period to understand the implication of such service alteration. Future research should also focus on the effects on long-term mortality and morbidity as well as financial implications on hospitals as a result of these changes.     

Bariatric surgery in patients with previous COVID-19 infection

BackgroundThe process of reintroducing bariatric surgery to our communities in a COVID-19 environment was particular to each country. Furthermore, no clear recommendation was made for patients with a previous COVID-19 infection and a favorable outcome who were seeking bariatric surgery.ObjectivesTo analyze the risks of specific complications for patients with previous COVID-19 infection who were admitted for bariatric surgery.SettingEight high-volume private centers from 5 countries.MethodsAll patients with morbid obesity and previous COVID-19 infection admitted for bariatric surgery were included in the current study. Patients were enrolled from 8 centers and 5 countries, and their electronic health data were reviewed retrospectively. The primary outcome was to identify early (<30 d) specific complications related to COVID-19 infection following bariatric surgery, and the secondary outcome was to analyze additional factors from work-ups that could prevent complications.ResultsThirty-five patients with a mean age of 40 years (range, 21–68 yr) and a mean body mass index of 44.3 kg/m² (±7.4 kg/m²) with previous COVID-19 infection underwent different bariatric procedures: 23 cases of sleeve (65.7 %), 7 cases of bypass, and 5 other cases. The symptomatology of the previous COVID-19 infection varied: 15 patients had no symptoms, 12 had fever and respiratory signs, 5 had only fever, 2 had digestive symptoms, and 1 had isolated respiratory signs. Only 5 patients (14.2 %) were hospitalized for COVID-19 infection, for a mean period of 8.8 days (range, 6–15 d). One patient was admitted to an intensive care unit and needed invasive mechanical ventilation. The mean interval time from COVID-19 infection to bariatric surgery was 11.3 weeks (3–34 wk). The mean hospital stay was 1.7 days (±1 d), and all patients were clinically evaluated 1 month following the bariatric procedure. There were 2 readmissions and 1 case of complication: that case was of a gastric leak treated with laparoscopic drainage and a repeated pigtail drain, with a favorable outcome. No cases of other specific complications or mortality were recorded.ConclusionMinor and moderate COVID-19 infections, especially the forms not complicated with invasive mechanical ventilation, should not preclude the indication for bariatric surgery. In our experience, a prior COVID-19 infection does not induce additional specific complications following bariatric surgery.     

Impact of COVID-19 on cardiac surgical training: Our experience in the United Kingdom

The current evolving global pandemic caused by coronavirus disease-2019 (COVID-19) has dramatically impacted global health care systems, resulting in governments taking unprecedented measures to contain the spread of the infection, with adaptations by health care organizations. Research into understanding the pathophysiology behind this virus, to ascertain best medical management and treatment, has been accelerated to keep up with the rapidly evolving situation. There has been redeployment of medical and nursing staff to the frontlines and redistribution of health care resources. In addition, the cancellation of elective surgery and centralization of services to treat high-risk surgical cases will all, undeniably, have an impact on current surgical training with possible future implications. We aim to explore the impact COVID-19 is having on cardiac surgical training in the UK and what future implications this may have.     

Bariatric surgery and COVID-19 outcomes: a systematic review and meta-analysis

BackgroundObesity and its associated complications have a negative impact on human health. Metabolic and bariatric surgery (MBS) ameliorates a series of clinical manifestations associated with obesity. However, the overall efficacy of MBS on COVID-19 outcomes remains unclear.ObjectivesThe objective of this article is to analyze the relationship between MBS and COVID-19 outcomes.SettingA meta-analysis.MethodsThe PubMed, Embase, Web of Science, and Cochrane Library databases were searched to retrieve the related articles from inception to December 2022. All original articles reporting MBS-confirmed SARS-CoV-2 infection were included. Outcomes including hospital admission, mortality, intensive care unit (ICU) admission, mechanical ventilation utilization, hemodialysis during admission, and hospital stay were selected. Meta-analysis with fixed or random-effect models was used and reported in terms of odds ratios (ORs) or weighted mean differences (WMDs) along with their 95% confidence intervals (CIs). Heterogeneity was assessed with the I² test. Study quality was assessed using the Newcastle-Ottawa Scale.ResultsA total of 10 clinical trials involving the investigation of 150,848 patients undergoing MBS interventions were included. Patients who underwent MBS had a lower risk of hospital admission (OR: .47, 95% CI: .34–.66, I² = 0%), mortality (OR: .43, 95% CI: .28–.65, I² = 63.6%), ICU admission (OR: .41, 95% CI: .21–.77, I² = 0%), and mechanical ventilation (OR: .51, 95% CI: .35–.75, I² = 56.2%) than those who did not undergo surgery, but MBS did not affect hemodialysis risk or COVID-19 infection rate. In addition, the length of hospital stay for patients with COVID-19 after MBS was significantly reduced (WMD: −1.81, 95% CI: −3.11–.52, I² = 82.7%).ConclusionsOur findings indicate that MBS is shown to improve COVID-19 outcomes, including hospital admission, mortality, ICU admission, mechanical ventilation, and hospital stay. Patients with obesity who have undergone MBS infected with COVID-19 will have better clinical outcomes than those without MBS.     

Cardiac tamponade as a presentation of COVID-19 after cardiac surgery

We present two patients who turned positive for coronavirus disease 2019 (COVID-19) after elective cardiac surgery, developing postoperative pericardial effusion with tamponade. One of the patients who presented with tamponade had no other symptoms of COVID-19 infection. COVID-19 can rarely present with cardiac manifestations including pericardial effusion and tamponade. In the post cardiac surgery setting, this effect of the virus may be accentuated. Hence, a high index of suspicion and prompt management are the keys for a successful outcome.     

Early outcomes of lung resections in non-small cell lung cancer after COVID-19 pneumonia

ObjectiveThere is limited literature on patients with a history of COVID-19 pneumonia who underwent anatomical lung resection for non-small cell lung cancer (NSCLC). This study was aimed to share the early postoperative outcomes in patients who underwent lung resection after COVID-19 pneumonia.Materials and methodsWe retrospectively evaluated 30 patients who underwent lobectomy with thoracotomy and systematic mediastinal lymph node dissection due to NSCLC in a single center between November 2018 and September 2021. The patients were divided into two groups regarding COVID-19 pneumonia history; the COVID-19 group consisted of 14 patients (46.7%) and the non-COVID-19 group 16 (53.3%) patients. The patients’ age, gender, comorbidity, Charlson Comorbidity Index (CCI) score, forced expiratory volume in 1 s (FEV1) value, tumor type and size, resection type, postoperative air leak duration, total drainage volume, drain removal time, postoperative complications, and length of stay (LOS) were recorded.Results9 (30%) patients were female, and 21 (70%) were male. The mean age was 62.1 ± 8.91 years. Our comparison of postoperative air leak duration, total drainage volume, time to drain removal, postoperative complications, and LOS between the COVID-19 and non-COVID-19 groups revealed no statistically significant difference.ConclusionAnatomical lung resection can be performed safely in NSCLC patients with a history of COVID-19 pneumonia without significant difference in early postoperative morbidity and mortality.     

Prosthetic aortic valve endocarditis complicated by COVID-19 and hemorrhage

The novel coronavirus, now termed SARS-CoV-2, has caused a significant global impact in the space of 4 months. Almost all elective cardiac surgical operations have been postponed with only urgent and emergency operations being considered in order to maximise resource utilisation. We present a case of a 69-year old lady with an infected prosthetic aortic valve for consideration of urgent inpatient surgery. Despite being asymptomatic and testing negative initially for COVID-19 RT-PCR swab, further investigations with CT revealed suspicious findings. She subsequently tested positive on a repeat swab and unfortunately deteriorated rapidly with complications including gastro-intestinal and intracerebral haemorrhage.     

The Pan London Emergency Cardiac Surgery service: Coordinating a response to the COVID-19 pandemic

Over the last 4 months, the novel coronavirus, SARS-CoV-2, has caused a significant economic, political, and public health impact on a global scale. The natural history of the disease and surge in the need for invasive ventilation has required the provision of intensive care beds in London to be reallocated. NHS England have proposed the formation of a Pan-London Emergency Cardiac surgery (PLECS) service to provide urgent and emergency cardiac surgery for the whole of London. In this initial report, we outline our experience of setting up and delivering a pan-regional service for the delivery of urgent and emergency cardiac surgery with a focus on maintaining a COVID-free in-hospital environment. In doing so, we hope that other regions can use this as a starting point in developing their own region-specific pathways if the spread of coronavirus necessitates similar measures be put in place across the United Kingdom.     

Successful mobile extracorporeal membrane oxygenator for COVID-19 severe respiratory failure

High volume extracorporeal membrane oxygenation (ECMO) centers have developed mobile ECMO programs in recent years to facilitate the implementation of ECMO support at hospitals with lower capabilities, and transfer these patients for further care. We report a case of mobile ECMO on a patient with coronavirus disease 2019-related acute respiratory distress syndrome, and discuss the potential application in the current severe acute respiratory syndrome coronavirus 2 pandemic.
