The impact of COVID-19 on a South African pediatric cardiac service: implications and insights into service capacity.

Background and Objectives: The Western Cape public pediatric cardiac service is under-resourced. COVID-19 regulations are likely to have long-term effects on patient care but may provide insight into service capacity requirements. As such, we aimed to quantify the impact of COVID-19 regulations on this service. Methods: An uncontrolled retrospective pre-post study of all presenting patients over two, one-year periods; the pre-COVID-19 period (01/03/2019-29/02/2020) and the peri-COVID-19 period (01/03/2020-28/02/2021). Results: Admissions decreased by 39% (624 to 378) and cardiac surgeries decreased by 29% (293 to 208) in the peri-COVID-19 period, with an increase in urgent cases (PR:5.99, 95%CI:3.58-10.02, p < 0.001). Age at surgery was lower in the peri-COVID-19 period, 7.2 (2.4-20.4) vs. 10.8 (4.8-49.2) months (p < 0.05), likewise, age at surgery for transposition of the great arteries (TGA) was lower peri-COVID-19, 15 (IQR:11.2-25.5) vs. 46 (IQR:11-62.5) days (p < 0.05). Length of stay 6 (IQR:2-14) vs. 3 days (IQR:1-9) (p < 0.001), complications (PR:1.21, 95%CI:1.01-1.43, p < 0.05), and age-adjusted delayed-sternal-closure rates (PR:3.20, 95%CI:1.09-9.33, p < 0.05) increased peri-COVID-19. Conclusion: Cardiac procedures were significantly reduced in the peri-COVID-19 period which will have implications on an overburdened service and ultimately, patient outcomes. COVID-19 restrictions on elective procedures freed capacity for urgent cases, demonstrated by the absolute increase in urgent cases and significant decrease in age at TGA-surgery. This facilitated intervention at the point of physiological need, albeit at the expense of elective procedures, and also revealed insights into capacity requirements of the Western Cape. These data emphasize the need for an informed strategy to increase capacity and reduce backlog whilst ensuring minimal morbidity and mortality.Graphical Abstract.

A case series evaluating the effect of esmolol therapy to treat hypoxemia in COVID-19 patients on VV-ECMO.

When COVID-19 ARDS abolishes pulmonary function, VV-ECMO can provide gas exchange. If oxygenation remains insufficient despite maximal VV-ECMO support, the addition of esmolol has been proposed. Conflict exists, however, as to the oxygenation level which should trigger beta-blocker initiation. We evaluated the effect of esmolol therapy on oxygenation and oxygen delivery in patients with negligible native lung function and various degrees of hypoxemia despite maximal VV-ECMO support. We found that, in COVID-19 patients with negligible pulmonary gas exchange, the generalized use of esmolol administration to raise arterial oxygenation by slowing heart rate and thereby match native cardiac output to maximal attainable VV ECMO flows actually reduces systemic oxygen delivery in many cases.

Intraoperative ventricular septal rupture: A case report.

Ventricular septal rupture (VSR) is a rare complication of myocardial infarction that requires surgical repair. Herein, we describe a case of intraoperative VSR requiring patch repair and postoperative extracorporeal membrane oxygenation (ECMO) support. This case highlights the risk factors, patient presentation, and management recommendations for this potentially lethal pathology.

An Unusual cause of Endocarditis.

A man in his 20s attended the emergency department with three days of fever, headache, reduced appetite and a sore throat. COVID-19 point-of-care test was negative. Blood cultures grew a gram-negative coccobacillus, Neisseria elongata Following an episode of confusion, MRI head revealed septic emboli. Prolapse of the mitral valve with regurgitation was noted on echocardiography. Infection was found to have originated from multiple dental caries and treatment required a combination of dental extraction, prolonged antibiotic therapy and surgery for mitral valve repair.N. elongata is part of the normal oropharyngeal flora but is also a rare cause of endocarditis. There are no established treatment guidelines for endocarditis of this aetiology. N. elongata endocarditis may present atypically, with a murmur only developing several days later. 'Classical' stigmata should not be relied on to make a diagnosis. N. elongata predominantly affects the left side of the heart and predisposes to embolic events.

A rare care of Lomentospora prolificans sternal wound infection post aortic valve replacement-an approach to surgical management.

A 77-year-old woman underwent surgical aortic valve replacement via hemisternotomy. Her post-operative course was unremarkable. Owing to travel and contact restrictions during the COVID pandemic, she was unable to attend routine follow up. She continued review with her local medical officer in regional New South Wales. Post 6 months following her index surgery, she was referred to the Infectious Disease Clinic of her local hospital with a non-healing lesion at the base of her hemi-sternotomy wound. Computed tomography revealed a deep sternal wound infection which extended deep to bone. She was admitted to hospital for treatment. The primary pathogen identified was Lomentospora prolificans-a dangerous fungus that affects immunosuppressed patients. Strong antifungal and adjunctive antibiotics did not contribute much to clearance of infection. Radical surgical debridement was required to obtain clean tissue margins.

Multidisciplinary paper on patient blood management in cardiothoracic surgery in the UK: perspectives on practice during COVID-19.

The coronavirus (COVID-19) pandemic disrupted all surgical specialties significantly and exerted additional pressures on the overburdened United Kingdom (UK) National Health Service. Healthcare professionals in the UK have had to adapt their practice. In particular, surgeons have faced organisational and technical challenges treating patients who carried higher risks, were more urgent and could not wait for prehabilitation or optimisation before their intervention. Furthermore, there were implications for blood transfusion with uncertain patterns of demand, reductions in donations and loss of crucial staff because of sickness and public health restrictions. Previous guidelines have attempted to address the control of bleeding and its consequences after cardiothoracic surgery, but there have been no targeted recommendations in light of the recent COVID-19 challenges. In this context, and with a focus on the perioperative period, an expert multidisciplinary Task Force reviewed the impact of bleeding in cardiothoracic surgery, explored different aspects of patient blood management with a focus on the use of haemostats as adjuncts to conventional surgical techniques and proposed best practice recommendations in the UK.

An unusual site of a pericardial cyst in a child: A case report.

Pericardial cysts are rare congenital anomalies, often clinically silent and incidentally found on imaging. However, patients with pericardial cysts may present with chest pain, tachypnea, and, rarely, symptoms secondary to cardiac tamponade. Echocardiography (transthoracic or transesophageal) and chest computed tomography (CT) scan with contrast are diagnostic modalities of choice in patients with pericardial cysts. Conservative management is justified in asymptomatic patients, while a surgical approach is recommended in symptomatic patients. Here, we describe the case of a 12-year-old boy who underwent imaging during the coronavirus disease 2019 (COVID-19) pandemic and was incidentally found to have a pericardial cyst.

Increased social media utilization and content creation by cardiothoracic surgery programs during the coronavirus disease 2019 pandemic.

Objectives: The coronavirus disease 2019 (COVID-19) pandemic has changed the landscape of professional activities, emphasizing virtual meetings and social media (SoMe) presence. Whether cardiothoracic programs increased their SoMe presence is unknown. We examined SoMe use and content creation by cardiothoracic surgery programs during the COVID-19 pandemic. Methods: We searched the Accreditation Council for Graduate Medical Education to identify all cardiothoracic surgery residency programs (n = 122), including independent (n = 74), integrated (n = 33), and congenital (n = 15) training programs at 78 US cardiothoracic surgery teaching institutions. We then manually searched Google, Facebook, Instagram, LinkedIn, and Twitter to identify the associated residency and departmental accounts. The timeline for our search was between 10/2021 and 4/2022. March 2020 was used as the starting point for the COVID-19 pandemic. We also contacted the account managers to identify account content creators. The data are descriptively reported and analyzed. Results: Of 137 SoMe accounts from 78 US cardiothoracic surgery teaching institutions, 72 of 137 (52.6%) were on Twitter, 34 of 137 (24.8%) on Facebook, and 31 of 137 (22.6%) on Instagram. Most accounts were departmental accounts (105/137 = 76.6%) versus 32 of 137 (23.4%) training program accounts. Most training program-specific SoMe accounts across all platforms were created after the COVID-19 pandemic, whereas departmental accounts were pre-existing (P < .001). The most pronounced SoMe growth was on Instagram at the training program level, with 91.7% of Instagram accounts created after the pandemic. Trainees are the content creators for 94.4% of residency accounts and 33.3% of departmental accounts. Facebook's presence was stagnant. Congenital training programs did not have a specific SoMe presence. Conclusions: SoMe presence by cardiothoracic surgery training programs and departments has increased during the pandemic. Twitter is the most common platform, with a recent increased trend on Instagram. Trainees largely create content. SoMe education and training pathways may be needed for involved trainees to maximize their benefits.

Narrative Review of New Insight into the Influence of the COVID-19 Pandemic on Cardiovascular Care.

Background and Objectives: The purpose of this paper was to perform a literature review on the effects of the COVID-19 pandemic on cardiothoracic and vascular surgery care and departments. Materials and Methods: To conduct this evaluation, an electronic search of many databases was conducted, and the resulting papers were chosen and evaluated. Results: Firstly, we have addressed the impact of COVID-19 infection on the cardiovascular system from the pathophysiological and treatment points of view. Afterwards, we analyzed every cardiovascular disease that seemed to appear after a COVID-19 infection, emphasizing the treatment. In addition, we have analyzed the impact of the pandemic on the cardiothoracic and vascular departments in different countries and the transitions that appeared. Finally, we discussed the implications of the cardiothoracic and vascular specialists' and residents' work and studies on the pandemic. Conclusions: The global pandemic caused by SARS-CoV-2 compelled the vascular profession to review the treatment of certain vascular illnesses and find solutions to address the vascular consequences of COVID-19 infection. The collaboration between vascular surgeons, public health specialists, and epidemiologists must continue to investigate the impact of the pandemic and the response to the public health issue.

Acute COVID-19 Pneumonia Unmasking a Large Left Atrial Myxoma

This is a case of acute coronavirus disease 2019 pneumonia that revealed an incidental large atrial myxoma with obstructive physiology that ultimately required emergent treatment with a definitive atriotomy and resection of the underlying myxoma.

Massive lung necrosis due to microwave ablation in an octogenarian required urgent lobectomy.

We present a rare complication of microwave ablation (MWA) in a male patient in his 80s. His massive pulmonary necrosis and tension pneumothorax required urgent surgery. However, the damage to the lung tissue was too large, deep and fragile. We failed to suture or conduct wedge resection on the lung lesion, so, left upper lobectomy was necessary. Therefore, we suggest that it is probably possible to reduce the frequency and time threshold when performing MWA for the elderly with comorbidities.

Treatment of a pneumatocele in a COVID-19 patient with endobronchial valves.

A man in his 40s was admitted to his local hospital 6 days after the first vague symptoms of COVID-19. His general condition deteriorated, and he was treated in the intensive care unit but did not require mechanical ventilation. During his recovery, he experienced a cough spell, after which his dyspnoea recurred and rapidly increased. CT pulmonary angiogram showed a 10×18 cm cavitary lesion with an air-fluid level and surrounding atelectasis of the right lower lobe. A one-way valve mechanism had developed, leading to the formation of a pneumatocele. The patient was treated by occlusion of all bronchial segments of the right lower lobe with endobronchial valves, and the pneumatocele was evacuated with a pigtail catheter. The valves were removed 4 weeks after insertion, and the right lower lobe re-expanded. Six months after treatment, the patient had recovered completely and almost regained his former lung function.

Fear of COVID-19 leading to late presenting myocardial infarction complicated by cardiogenic shock due to ventricular septal rupture.

Post myocardial ventricular septal rupture (VSR) is one of the most fatal complications of acute myocardial infarction (AMI) in spite of percutaneous and surgical closure. With the advancement of percutaneous coronary interventions in a timely manner, incidence of post MI VSR has declined remarkably. However, the COVID-19) pandemic-related late hospital presentations with AMI increases the possibilities of a potential upward shift in the incidence of post MI VSR. This case report aimed to increase awareness of negative contributions of the current pandemic to AMI and its fatal complications.

Digital communication platforms in cardiothoracic surgery during COVID-19 pandemic: keeping us connected or isolated?

During the COVID-19 pandemic, performing a surgeon's duties has become challenging while adhering to social distancing mandates. To aid in the continuity of healthcare services, rapid implementation of digital communication tools became a necessity. This is an account of experiences using digital communication platforms, namely Microsoft Teams and Zoom, for clinical and educative purposes in the field of Cardiothoracic Surgery in the UK. While enabling ongoing virtual clinical meetings, conferences and learning opportunities for residents with little face-to-face contact, are these digital communication platforms keeping us connected or isolated?

Challenges of remote consultations: a delayed diagnosis of aortic valve endocarditis complicated by recurrent intracranial events.

Embolic events causing stroke and intracranial haemorrhage are among the most catastrophic complications of infective endocarditis (IE).A female patient presented with acute unilateral weakness following a 3-month history of fever, for which she had multiple remote consultations with her general practitioner. A brain MRI confirmed a left sided infarct with haemorrhagic transformation. Blood cultures grew Streptococcus mitis and her cardiac imaging showed an aortic valve vegetation with severe aortic regurgitation. Following 2 weeks of antibiotics she developed a new cerebral haemorrhage associated with a mycotic aneurysm which was treated with two coils. After discussions within the multidisciplinary meeting, she underwent aortic valve replacement 3 weeks later. She made a remarkable recovery and was discharged.Our case highlights the importance of face-to-face clinical review in the post-COVID era. It stresses that the management of patients with infective endocarditis and neurological complications is challenging and requires a multidisciplinary approach.

Is it time to incorporate hands-on simulation into the cardiothoracic surgery curriculum?

The COVID pandemic has had huge implications for training in cardiothoracic surgery. The reduction in training opportunities has led to concerns from trainees globally regarding the impact on their learning and their training progression. Surgical simulation is effective in the development of technical skills in cardiothoracic surgery with numerous examples of low and high-fidelity simulators. Despite this the incorporation of such methods into training curricula worldwide is seldom. Core fundamentals are required to successfully implement surgical simulation into training programmes, which includes; commitment from trainers, regular sessions and structured feedback. Few programmes have demonstrated the successful incorporation of surgical simulation and there is a growing acceptance of its place in the speciality. As we recover from this challenging period it may be the right opportunity to evolve how we train our current and future trainees by incorporating hands-on simulation as a fundamental part of the cardiothoracic curriculum.

Efficacy of Transcutaneous Electrical Nerve Stimulation for Postoperative Pain, Pulmonary Function, and Opioid Consumption Following Cardiothoracic Procedures: A Systematic Review.

OBJECTIVE: Transcutaneous electrical nerve stimulation (TENS) is a minimally invasive method for treating pain. In the most recent review published in 2012, TENS was associated with increased pain relief following cardiothoracic surgery when compared to standard multimodal analgesia. The purpose of this systematic review and meta-analysis is to determine if adding TENS to current pain management practices decreases pain and analgesic use and improves pulmonary function for postcardiothoracic surgery patients. MATERIALS AND METHODS: CINAHL, MEDLINE, Cochrane Database of Systematic Reviews, PubMed, and ClinicalTrials.gov were searched using specific keywords. Covidence was used to screen, select studies, and extract data by two independent reviewers. The Cochrane Risk of Bias tool assessed risk of bias. Visual analog scale (VAS) and pulmonary function data were exported for meta-analysis using a random effects model. RESULTS: The search yielded 38 articles. Eight randomized controlled trials met inclusion criteria for the literature review. Five studies were included in the meta-analysis of pain at 24, 48, and 72 hours postoperatively. Data were analyzed using the standard mean difference (SMD). TENS had a significant impact on VAS at rest (-0.76 SMD [95% confidence interval, CI = -1.06 to -0.49], p < 0.00001) and with coughing (-1.11 SMD [95% CI = -1.64 to -0.56], p < 0.0001). FEV1 improved after 72 hours (1.00 SMD [95% CI = 0.66-1.35], p < 0.00001), as did forced vital capacity (1.16 SMD [95% CI = 0.23-2.10], p = 0.01). CONCLUSION: The addition of TENS therapy to multimodal analgesia significantly decreases pain following cardiothoracic surgery, increases the recovery of pulmonary function, and decreases the use of analgesics.
