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

Orthopedic surgical scoring in asymptomatic COVID-19 patients

Aim: The purpose of this study is to create a scoring system to decide which patient will take maximum precautions while the covid 19 disease continues. Taking maximum precautions is not always possible in all surgical procedures. Therefore, surgical scoring in asymptomatic patients, selecting patients who need maximum precautions, and taking the necessary precautions for these patients will prevent unnecessary use of the equipment. Material(s) and Method(s): A total of 347 who were surgically treated for emergency or elective procedures between March 11 and November 11, 2020 were included in the study. Of these patients, 277 patients whose data could be accessed were included in the study. A scoring system has been created. Patients were divided into 2 groups: bearing low and high risk. Patients with a score above 10 were identified as having a high surgical risk, and those with a score below 10 were identified as having a low surgical risk. Result(s): There were 132 patients in Group 1 and 145 patients in Group 2. It was observed that 29 of 277 patients became positive within the first month. Two of these patients were in Group 1 and 27 of them were in Group 2. It was observed that COVID-19 antibody or PCR tests gave more positive results in patients in Group 2 in the first month compared to two patients in Group 1. The highest positivity rate in Group 2 was observed in the arthroscopy group. Discussion(s): Advanced precautions should be taken in patients with high surgical risk scores. In patients with low surgical risk scores, less strict precautions can be taken.Copyright © 2023, Derman Medical Publishing. All rights reserved.

Frail Scale as Predictor of 30-Day Postoperative Outcomes in Geriatric Surgical Patients at a Tertiary Hospital in the Philippines from June 2020 to June 2021

Introduction: The geriatric population is a growing subset of surgical patients. Specialized surgical risk management is important since physiologic changes are only loosely associated with age. Searching for better risk assessment tools, we come across the 5-point FRAIL scale, a validated measure of weakness and physiologic malfunction resulting to vulnerability to stressors like surgery. Method(s): Our objective was to assess the effectiveness of FRAIL scale in predicting 30-day complications in geriatric surgical patients. We conducted this research at a tertiary hospital in the Philippines from June 2020 to June 2021. Patients were classified preoperatively as frail or robust, and they were monitored 30 days post-surgery for adverse outcomes. Result(s): Out of 100 patients, fifty-seven were frail. Postoperatively, 20% had complications, while 18% expired, with 76% of all adverse outcomes belonging to frail group. FRAIL scale had a significantly better predictive value as compared with Charlson comorbidity index and ACS surgical risk calculator in cases of mortality, but there was no significant difference in predicting morbidity for the three assessment tools. The increase in adverse outcomes compared with previous years was attributed to (1) the proportion of colorectal procedures, and (2) patients were probably in a more advanced stage of illness due to the delays in treatment caused by the COVID-19 pandemic. Conclusion(s): In conclusion, FRAIL scale is an easy-to-use and effective risk assessment tool for geriatric surgical patients. Since most frail patients admit of weakness, resistance training and aerobic exercises may be an appropriate strategy to improve surgical outcomes.

When and What to Consider Knee Arthroscopy Surgery in Post-COVID 19 Infected Patients

Coronavirus disease 19 (COVID-19) is the worst pandemic ever recorded in history, as of this day more than 545 million people infected and more than 6 million cumulative deaths. COVID 19 is primarily respiratory disease, however non-respiratory presentations that could be manifested are venous and arterial thromboembolic events. Both pulmonary embolism (PE) and deep vein thrombosis (DVT) are the most frequently thrombotic events in COVID-19. Knee arthroscopy surgery is the one of the most common orthopedic surgical procedures nowadays, with the most common procedures are meniscectomy, meniscal repair and cruciate ligament reconstruction. Although knee arthroscopy is known to be a safe procedure, several complications could be found with the 3 most common complications are DVT, effusion and synovitis, and PE. We reported a case series of four patients with DVT post knee arthroscopy anterior cruciate ligament reconstruction during 2021. The DVT diagnosis was retained on clinical presentation and elevated of D-dimer testing. The patient's mean age was 35,25 years, and all of the patients had no risk factors of DVT, although they had COVID-19 infection within 3 months before surgery. The most common clinical presentation was swelling on the lower leg (around the ankle) with slightly pain and numbness. Only one patient had severe pain around the thigh. All of the patients had elevated D-dimer testing result with mean of D-dimer 1250 (normal value < 500). Only one patient had sonography testing and found proximal DVT. One of the patients had DVT at post operative day (POD) 3, one at POD 4 and the other two at POD 5. Three of the patients improved with oral anticoagulant therapy using rivaroxaban (XARELTO). In one patient the symptom was not improved after two days oral anticoagulant therapy and underwent thrombectomy by vascular surgeon. DVT is the most common complication of knee arthroscopy and also the most common non-respiratory events of COVID-19 infection. Routinely administration of thromboprophylaxis agent was not recommended, pre-operative risk assessment of DVT should be used, especially in post-COVID 19 patients.

Utility of multidisciplinary meetings in paediatric and adolescent oncofertility

Study objective: Multidisciplinary meetings (MDMs) are increasingly implemented in complex care based on the principle that they lead to evidence-based treatment recommendations, foster adherence to clinical guidelines, induce better team performance and improve medical care. In oncofertility, the uncertain outcomes of fertility preservation procedures in children contribute to the complexity of decision-making. There is limited published information on the influence of MDMs on paediatric and adolescent oncofertility care. Aim(s): To describe the implementation, characteristics & outcomes of multidisciplinary meetings (MDMs) in a paediatric oncofertility setting. Method(s): A retrospective medical records review of oncofertility MDMs held between April 2020 and March 2021 at the Royal Children's Hospital Melbourne. Inductive content analysis of the reasons for MDM was undertaken. MDM documentation was scored out of 24, according to a Victorian Paediatric Integrated Cancer Service quality assurance checklist for MDMs, (1)) which included consent for MDM, nature of attendees, quality of discussion and documentation. Result(s): Of the 169 oncology patients treated at the Royal Children's Hospital between 1st April 2020 and 31st March 2021, MDMs were required for 40 patients (23.7%). The median number of clinical attendees was 10, and included craft groups from both paediatric and adult centres (oncology, oncofertility, gynaecology, clinical ethics, endocrinology, paediatric surgery, anaesthetics, haematology, fertility specialists and reproductive scientists). Fifty-four percent (n=22) of MDMs were for male patients (median age 8.4 [0.1-16.5] years) and 46% for females (n=18, median age 8.1[0.4-16.3] years). The commonest diagnoses presented at MDM were brain tumours (27.5%), leukemia (25%), and non malignant conditions (19.5%). Approximately 77% of all MDM patients were going to receive treatment that put them at high infertility risk and 62.5% had co-morbidities. MDMs included the following themes (i) likelihood of successful parenthood: disease progression, prognosis, neurocognitive decline;(ii) certainty or otherwise of planned treatment and infertility risks;(iii) mitigation of anaesthetic and surgical risks;(iv) ethical concerns;(v) organizational capacity and logistics in the face of covid restrictions or high dependent care between centres (vi) child and family of risks, expectations and their values regarding fertility preservation. In 87.5% of cases, it was deemed permissible to offer fertility preservation. The median score for the MDMs derived from the quality assurance checklist was 16. Conclussion: MDMs acted as a valuable educational and communication tool improving situational awareness, building shared mental models, assisting with risk mitigation and oncofertility planning.Copyright © 2023

Finding an Answer for an Adolescent with Back Pain

Case report - Introduction: This is the case of an adolescent referred to rheumatology following 5 years of back pain. After years of trying a number of treatments without much success, the cause was found to be a previously undiagnosed urological pathology. The case highlights awareness of non-rheumatological causes and incidental findings which can redirect a patient towards more appropriate treatment and reduce the potential for long-term adverse health issues and anxiety. Case report - Case description: B was referred age 16 to rheumatology with a 5-year history of lower back pain. She had previously seen paediatricians with symptoms initially attributed to constipation due to intermittent straining and hard stool. However, constipation remedies had not relieved the pain which progressed gradually to a more persistent dull ache with impact on daily activities. Various analgesics (including paracetamol and non-steroidal anti-inflammatories), exercises and acupuncture had not helped. There was no history of recurrent urinary tract infections or symptom correlation with fluid intake, menstruation or bowel habit. No inflammatory features or connective tissue disease symptoms were noted and family history was unremarkable Clinical examination was normal apart from mild tenderness in the lumbar region. Rheumatoid factor was borderline positive (15 iu/mL) with the rest of blood tests normal including renal function, inflammatory markers (CRP, ESR), anti CCP and ANA. She had minimal microscopic haematuria without proteinuria. MRI spine in 2015 was normal. In view of her young age and symptoms affecting daily activities, STIR sequence spinal MRI was requested. This excluded any new or old inflammatory changes but incidentally identified a dilated left pelvi-calyceal system. Renal ultrasound confirmed a grossly hydronephrotic left kidney with hydroureter and minimal renal tissue suggesting longstanding obstruction. No calculi were seen. The patient was referred to urologists. Further investigations (including MRI abdomen) confirmed similar findings and a distal ureteric stricture. A MAG 3 renogram showed a normal right kidney but only 12% functioning of the left kidney. Urologists have advised surgery (removal of left kidney and ureter) which may relieve symptoms or a conservative non-surgical approach (continue analgesia, physiotherapy and monitoring). The patient and her family are relieved to have a possible cause identified and are considering the surgical option due to ongoing flank discomfort. Case report - Discussion: This was an interesting finding of hydroureter and hydronephrosis causing longstanding back pain presenting to rheumatologists. Until completion of the spondyloarthropathy protocol MRI (STIR images), aetiology had been unclear. Hydronephrosis and hydroureter has no specific age or racial predilection. Signs and symptoms may depend on whether obstruction is acute/chronic. Chronic cases may be asymptomatic or present as a dull discomfort (like this case). Some cases may only present in adulthood with pain precipitated by fluid intake. Blood tests may show impaired kidney function. Post-mortem studies suggest 50% of people have at least one renal abnormality (e.g., renal cysts, duplex ureters) with autopsy series incidence of hydronephrosis reported as 3.1%. Causes include anatomical abnormalities such as vesico-ureteric reflux, urethral strictures (usually present in childhood), calculi, benign prostatic hyperplasia, or intrapelvic neoplasms, pregnancy and infections (e.g., TB). Sudden onset unilateral renomegaly was reported in one case of primary Sjogren's with lymphocytic interstitial nephritis and positive Sjogren's autoantibodies. Our patient has no clinical or serological evidence of connective tissue disease. Minor pelvi-calyceal distension can occur as a normal finding in wellhydrated patients and pregnancy. However, significant hydronephrosis requires assessment to determine cause as it may affect long term renal function. Imaging via computed tomography, ultrasound and urograms can help guide further management. In this case the preceding cause and duration of pathology is unknown. Sterile, giant hydronephrosis treatment options include observation and ureteric stent or nephrostomy in patients unfit for surgery. Nephrectomy is advised for pain and recurrent infection in a non-functioning kidney. Complications may include bowel perforation, vascular injury and urine leakage. Both open and minimally invasive procedures have good reported outcomes. The COVID-19 pandemic and exams have affected timing of any elective procedures and the patient understands surgery may or may not offer complete symptom resolution. Case report - Key learning points: . Non-inflammatory causes of back pain should always be considered in cases of persistent back pain, particularly in young people to ascertain if there is a treatable cause . Hydronephrosis cases can be asymptomatic or present with vague, intermittent, non-specific abdominal symptoms with normal physical examination with or without haematuria. This can cause diagnostic uncertainty and delay referral to urology and appropriate renal investigations . Assessment of renal function (including MAG 3 renogram) is important to guide further management . Surgical interventions (pyeloplasty/nephrectomy) may ease symptoms long term but there is no guarantee of a successful outcome and operative risks need to be considered too . Left undiagnosed, potentially this patient could have had further disruption to daily activities and both physical and mental well being.

CHRONIC EMPYEMA MANAGED WITH TUBE THORACOSTOMY

SESSION TITLE: Problems in the Pleura Case Posters 2 SESSION TYPE: Case Report Posters PRESENTED ON: 10/17/2022 12:15 pm - 01:15 pm INTRODUCTION: Hematologic malignancies can often be complicated by pleural effusion due to leukemic infiltration of the pleura (1). Long term management of resulting chronic plural effusion can be complicated when there is evidence of trapped lung. Subsequent infection may lead to development of chronic empyema which can be difficult to manage in chronically ill patients (2). CASE PRESENTATION: A 65-year-old male with history of chronic myeloid leukemia status post stem cell transplant was admitted with dyspnea and cough. Computed tomography (CT) chest imaging revealed increased volume loss on the left with new air fluid level in a chronic left pleural effusion. (Image 1) Patient's history was significant for chronic left pleural effusion, which was first identified in 2015 and found to be a malignant effusion with evidence of leukemia involvement. Repeat imaging in 2018 (Image 2) revealed continued chronic pleural effusion. Patient was admitted in August 2021 with COVID-19 pneumonia and CT Chest showed chronic loculated left sided pleural effusion. Patient elected to continue to monitor the chronic effusion, which was completed as outpatient every 4 to 6 weeks (Image 3). He remained clinically stable until the presentation to a hospital in January 2022. The chronic empyema was initially managed with tube thoracostomy, intrapleural fibrinolytics and antibiotics. Cultures were significant for Moraxella catarrhalis and Streptococcus pneumoniae. He was determined to be a poor surgical candidate for decortication and treatment with empyema tube was initiated. The empyema tube was incrementally withdrawn as an outpatient and subsequently removed with good clinical recovery. DISCUSSION: Chronic empyema is characterized by thickened parietal and visceral pleura which limits the ability of the lung to re-expand. Surgical management with decortication is the definitive management, however, in poor surgical candidates, management becomes more complicated. Open pleural drainage with an open pleural window can be considered. An alternative option converts tube thoracostomy to open pleural drainage, as was utilized in this patient (2). While comparison of surgical vs non-surgical management of empyema suggests similar mortality (3), non-surgical management of chronic empyema needs more investigation to determine the optimal treatment modality. CONCLUSIONS: Empyema remains a difficult condition to manage. Treatment modalities of chronic empyema are limited in those patients who remain poor surgical candidates.

The impact of the COVID-19 pandemic on the decrease in the use of intensive care units in the postoperative period of anatomic lung resections. A retrospective analysis

Objective: COVID-19 pandemic required optimization of hospital institutional flow, especially regarding the use of intensive care unit (ICU) beds. The aim of this study was to assess whether the individualization of the indication for postoperative recovery from pulmonary surgery in ICU beds was associated with more perioperative complications. Method: retrospective analysis of medical records of patients undergoing anatomic lung resections for cancer in a tertiary hospital. The sample was divided into: Group-I, composed of surgeries performed between March/2019 and February/2020, pre-pandemic, and Group-II, composed of surgeries performed between March/2020 and February/2021, pandemic period in Brazil. We analyzed demographic data, surgical risks, surgeries performed, postoperative complications, length of stay in the ICU and hospital stay. Preventive measures of COVID-19 were adopted in group-II. Results: 43 patients were included, 20 in group-I and 23 in group-II. The groups did not show statistical differences regarding baseline demographic variables. In group-I, 80% of the patients underwent a postoperative period in the ICU, compared to 21% in group-II. There was a significant difference when comparing the average length of stay in an ICU bed (46 hours in group-I versus 14 hours in group-II-p<0.001). There was no statistical difference regarding postoperative complications (p=0.44). Conclusions: the individualization of the need for ICU use in the immediate postoperative period resulted in an improvement in the institutional care flow during the COVID-19 pandemic, in a safe way, without an increase in surgical morbidity and mortality, favoring the maintenance of essential cancer treatment.

Transatrial Balloon-Expandable Valve Implantation for Symptomatic Mitral Stenosis With Severe Annular Calcification—A Hybrid Solution

Background: Treatment of symptomatic mitral valve stenosis in severe mitral annular calcification is a surgical challenge. Transcatheter options include transfemoral transcatheter mitral valve replacement (TMVR), which poses its own risks, the most significant is left ventricular outflow tract (LVOT) obstruction. Transatrial hybrid TMVR optimizes advantages of both traditional open-heart surgery and transcatheter valve replacement. Methods: Retrospective review of seven high-risk patients (deemed ineligible for traditional surgery) undergoing transatrial implantation of a SAPIEN 3 valve (Edwards Lifesciences, Irvine, CA) in the mitral position for severe symptomatic mitral stenosis. Laceration of the Anterior Mitral leaflets to Prevent Outflow ObstructioN procedure was not considered due to heavy leaflet calcifications. Results: Seven patients treated consecutively from June 2020 to July 2021 were included in this analysis. Mean age was 77 years;six were females, one was male. Average STS score was 9.8. Three patients had New York Heart Association (NYHA) class IV heart failure. Mean left ventricular ejection fraction was 62%. Dominant mitral valve pathology included mitral stenosis in all patients. Mean mitral valve gradient was 12 mmHg. All patients had circumferential annular calcification except one, who had predominantly anterior calcification. All patients received the Edwards SAPIEN 3 valve and had anterior leaflet resection. Surgical approach was at the discretion of the attending cardiac surgeon. Mean cardiopulmonary bypass time was 85 minutes;mean cross-clamp time was 36 minutes. No anchoring felt was used. Technical success was 100%, with no device embolization. There was no clinically significant LVOT obstruction. There were two deaths: one occurred during index hospitalization due to worsening heart failure secondary to torrential tricuspid regurgitation, and the second was 2 months later due to COVID-19 infection. Conclusion: Surgical hybrid transatrial TMVR for patients at high surgical risk is technically feasible with high procedure success. A relatively shorter cardiac ischemic duration, direct visualization and resection of the anterior mitral leaflet can allow for safe TMVR without risk of LVOT obstruction.

COVID-19 in the perioperative setting: A review of the literature and the clinical landscape.

The COVID-19 pandemic has dramatically affected societies and healthcare systems around the globe. The perioperative care continuum has also been under significant strain due to the pandemic-tasked with simultaneously addressing surgical strains and backlogs, infection prevention strategies, and emerging data regarding significantly higher perioperative risk for COVID-19 patients and survivors. Many uncertainties persist regarding the perioperative risk, assessment, and management of COVID-19 survivors-and the energy to catch up on surgical backlogs must be tempered with strategies to continue to mitigate COVID-19 related perioperative risk. Here, we review the available data for COVID-19-related perioperative risk, discuss areas of persistent uncertainty, and empower the perioperative teams to pursue evidence-based strategies for high quality, patient-centered, team-based care as we enter the third year of the COVID-19 pandemic.

Early Outcomes of Elderly Hip Fracture Management during the COVID-19 Pandemic: A Report from the Philippines

Introduction: The multidisciplinary model of management for fragility hip fractures has only been recently introduced in the Philippines. Its development at the national and local level is made more difficult by the COVID-19 pandemic. To our knowledge, this is the first study to provide a comprehensive report on the clinical characteristics, current management and early outcomes of fragility hip fracture patients admitted during the COVID-19 pandemic in the setting of a country with an emerging economy. Methods: A multicenter prospective cohort study was conducted in the Philippines involving 12 hospitals from June 16, 2020 to February 28, 2021 during the Extended Community Quarantine Period during the COVID-19 pandemic. The clinico-demographic characteristics, treatments, and follow-up data at 30 days post-injury were gathered using the Research Electronic Data Capture (REDCAP) database system, using a minimum common data (MCD) which was adopted from the FFN MCD. Results: A total of 158 elderly patients (>60 years old) with fragility hip fractures were eligible for the study. 9 patients (5.7%) were confirmed or suspected to have COVID-19 infection. The median time of injury-to-admission was at least 3 (IQR: 1.0-13.7) days. 80% of the patients underwent surgical intervention with a median time from admission-to-surgery of at least 5 (IQR: 2.5-13.6) days. Notably, all non-COVID admitted patients had not been reported to have contracted the virus during their hospital stay. The 30-day mortality and morbidity rate for acute fragility fractures were 3.7%. Only the presence of a COVID-19 infection was found to be an independent and poor predictor for early mortality (P = 0.010). Conservatively managed patients had a significantly higher morbidity rate than surgically treated patients (13.6% vs 1.8%;P = 0.031). All five deaths occurred in non-surgical patients with an ASA grade of at least III. Conclusion: We recommend prompt admission and multidisciplinary care for elderly hip fracture patients even during the COVID-19 pandemic. Short-term outcomes remain favorable for non-COVID patients with acute fragility fractures treated with surgery. While a suspected or confirmed COVID-19 infection was the only significant and independent pre-operative risk factor for early mortality, there is evidence in the literature as well as in this study that the benefit of surgery may well outweigh the risk of conservatively treating COVID-19 patients provided that they can be optimized appropriately for surgery.

Spanish Society of Cardio & Endovascular Surgery registry of interventions in patients with congenital heart disease: 2020, and retrospective of the previous 9 years

The Spanish Society of Cardiovascular & Endovascular Surgery presents the 2012-2020 report of the activity in congenital cardiovascular surgery, based on a voluntary and anonymous registration involving the most of Spanish centres. This article is complementary to the 2020 cardiovascular surgery annual report, and they are published together. In 2020, seriously damaged by the COVID-19 pandemic related to all sanitary fields, we observe a 14% drop in our congenital activity compared with 2019. Data from the previous 9 years are included, in order to obtain real information related to our activity in these relatively scarce pathologies. In the last nine years, a total of 18526 congenital heart surgeries were performed, accounting for 9.6% of major surgery (congenital + acquired) performed in Spain during that period. Of these surgeries, 81% of them required extracorporeal circulation and 19% not. We highlight the interventions in neonates and adult patients, which represent respectively 19% and 21% of the 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 not requiring 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 3.1% (Aristotle-6.48), and without cardiopulmonary bypass 2.41% (Aristotle-4.81). This data analysis shows accurate and reliable information about our surgery for congenital heart disease and allow us to compare ourselves within an international framework, and to organize strategies directed to improve our results.

Thrombosis of Mechanical Mitral Valve Prosthesis Treated With Fibrinolysis

Background: Mechanical prosthetic valve thrombosis is an uncommon but serious complication associated with high mortality and morbidity. Conventionally, prosthetic valve thrombosis is treated with surgical intervention, but recent literature has shown that slow-infusion of low-dose fibrinolytic therapy could be of equal efficacy. Case: A 27-year-old lady presented to the emergency department with a three-week history of worsening shortness of breath on background of mechanical mitral valve replacement for rheumatic mitral stenosis. She had recently been non-compliant with international normalised ratio (INR) checks for warfarin dosing in the setting of local lockdown for the COVID-19 pandemic. Transthoracic echocardiography revealed mechanical mitral valve thrombosis resulting in an immobile medial disc and severely restricted lateral disc, associated with severely elevated mitral inflow gradient (mean 42mmHg at 98 beats per minute) and severe pulmonary hypertension (right ventricular systolic pressure of 92mmHg). After discussion in a multidisciplinary cardiology and cardiothoracic surgical conference, the patient was treated with three daily doses of slow-infusion low-dose fibrinolytic therapy (25mg alteplase over six hours). On day three, there was complete resolution of symptoms, associated with resolution of valve thrombosis on repeat echocardiography. There were no bleeding or embolic complications, and the patient was discharged home three days later. Conclusions: This case highlights the utility of slow-infusion low-dose fibrinolytic therapy in the management of mechanical prosthetic valve thrombosis. This conservative approach may be a useful alternative in patients with high pre-operative surgical risk.

European Association of Urology COVID intermediate prioritisation group is poorly predictive of pathological high-risk among patients with renal tumours

Introduction & Objectives: The purpose of prioritisation is to minimise harm while safeguarding access to health care in times of reduced clinical resources. The EAU Guideline Office Rapid Reaction Group (GORRG) issued priority recommendations for use during the COVID-19 pandemic. We evaluated if the clinical prioritisation for suspected renal cell carcinoma (RCC) planned for surgery matched final pathological risk. Materials & Methods: From 23 March 2020 at the beginning of the first lock-down in the UK, patients with suspected RCC were prioritised according to GORRG recommendations until 10 October 2020. To increase statistical power, GORRG prioritisation was also retrospectively assigned to pre-lockdown RCC surgical cases, dating back to April 5 2019. Patient and tumour characteristics were assessed, as was priority group according to GORRG, TNM, and postoperative risk according to 2003 Leibovich scores. We assessed concordance between pre-operative GORGG prioritisation group and post-operative risk, and if stratification could be further improved by subgrouping of size. Results: 351 patients with suspected RCC were prioritised and underwent surgery, of which 16 were benign and 335 were RCC after specimen analysis. The intermediate priority group did not match the pathological risk group in 47.7%, with 25.7% and 16.4% of the group being pathological low and high risk, respectively. The low GORRG priority group harboured 14.9% intermediate and 1.06% high risk RCC, and the high GORRG priority group 27.9% intermediate and no low risk RCC respectively. Within the GORRG intermediate group, 34.2% of cT1b tumours were low risk, and 32.3% of cT2a tumours high risk. Analysing at 1 cm increments, 45.1% of 4-5cm tumours were low risk. The area under the receiver operating characteristics curve for priority groups in predicting matched postoperative risk group was 0.60 (95% CI 0.55-0.65). The sankey diagram shows patients categorised according to EAU GORGG guidelines (left) and pathological risk (right).(Figure Presented)Conclusions: The recommended prioritisation system can be error prone and should be prudently applied based on the centre’s needs. Particularly amongst the intermediate group, centres with clinical capacity should not defer intervention of cT2a tumours for longer than absolutely necessary and in severely limited resources may consider intermediate priority tumours <5cm as low priority.

Regional anaesthesia for infra-inguinal revascularisation in patients with symptomatic peripheral arterial disease

Introduction: General anaesthesia is considered to be an aerosol generating procedure. The global Covid-19 pandemic has resulted in review of practice to reduce risk to both patients and health care workers. The outcome of regional anaesthesia (RA) for infra-inguinal arterial reconstruction in patients with symptomatic occlusive atherosclerotic has been explored and compared with patients managed with general anaesthesia (GA). Methods: Patients undergoing infra-inguinal revascularisation between 2019-2020 were identified from a prospectively maintained administrative theatre dataset. Case-linkage was used to complete the dataset. Specific end points included to critical care admission and peri-operative mortality. Results: There were 204 patients identified (46 RA and 158 GA). The mean age of patients in both groups was 67-years and procedures were commonly performed in male patients (although the male:female ratio was higher in the RA group 2.8:1 than in the GA group 1.4:1). More patients in the RA had intervention for chronic limb threatening ischaemia (80% versus 59%). The interventions performed were comparable in both groups. The mean length of procedure was less in the RA group (142-minutes versus 160-minutes). No patients in the RA required admission to critical care (10 patients managed with GA required admission to critical care). The 30-day mortality was comparable in the RA and GA groups (2.2% and 1.9% respectively). Conclusions: Regional anaesthesia would appear to be feasible for patients undergoing infra-inguinal arterial reconstruction with a reduction in operating time and critical care admission without increased peri-operative risk.

Why do people remain in hospital after mastectomy?

Aims: Mastectomy is established as a safe day-case procedure. Amidst the ongoing COVID-19 pandemic it is essential to find ways to continue elective surgery with greater efficiency. The aim of this study is to establish factors associated with overnight admission after simple mastectomy, enabling more effective pre-operative planning. Methods: All patients undergoing simple mastectomy in our unit between January and October 2020 were included. Those undergoing immediate reconstruction were excluded. The electronic case notes were reviewed to include procedure performed and patient characteristics. Basic statistical analysis was performed. Results: 95 patients underwent simple mastectomy (28 with axillary clearance and 58 with sentinel node biopsy). 56% of procedures were day-case. Axillary clearance was more common in the inpatient compared to the day-case surgery group (24% vs 45%). Both average age and ASA were significantly lower in the day-case compared to the inpatient group (p<0.05). There was no significant difference in BMI or specimen weight between groups. 16 patients underwent simple mastectomy without drain insertion, none required admission. Of the patients admitted overnight following surgery, 50% were pre-planned admissions. 57% of these were for patients identified as high surgical or anaesthetic risk at pre-operative assessment. Overall 5 patients stayed in hospital due to patient preference. Conclusions: In addition to axillary surgery performed, age, ASA and perceived pre-operative risk are associated with overnight admission following simple mastectomy. Knowledge of these factors can better inform pre-operative planning. Providing enhanced post-operative support at home may enable more patients to be discharged on day of surgery.

An audit of surgical consent standards in patients undergoing elective ent surgery

Aim: Good Surgical Practice (RCS England) and GMC guidelines inform a surgeon's practice in the consent process for an operation. Since the Covid-19 pandemic, many surgical departments have converted from face-to-face to telephonic consultations. The clinic letter is of increased importance given that it forms a key part of the medical record which the patient should receive to ensure sufficient time and information to make an informed decision. Method: Clinic letters of patients undergoing elective ENT surgery at our trust over a four-week period were examined in this retrospective audit of compliance with RCSEng and GMC guidelines. Additional data was collected on clinician grade and proportion of letters sent to patients. Patients rated satisfaction with consultation on a five-point Likert scale. Results: 135 eligible patients were included in our audit and the majority were listed by a consultant (57%). In all domains, consultant letters were more likely to be comprehensive as compared to registrars. Overall quality of clinic letters was highly variable regarding documentation of diagnosis (52%), surgical risks (50%), discussion of alternative or no treatment (30%) and registrar discussion with consultant (31%). There was also a stark difference between registrars and consultants sending patients copies of clinic letters (10% vs 47%). Only 10% of patients received a leaflet on their condition. 90% of patients were either satisfied or very satisfied with their clinic consultation. Conclusions: Refresher sessions on consent, updated template letters and increased provision of patient information leaflets will be introduced to the ENT department, and improvements monitored with further re-audit.

Predictors of left ventricular ejection fraction recovery after transcatheter aortic valve replacement (TAVR)

Introduction: Transcatheter aortic valve replacement (TAVR) has proven benefits in patients with reduced left ventricular ejection fraction (LVEF). A significant proportion of them shows recovery of systolic function Objective: To analyse the main baseline, electrocardiographic and echocardiographic characteristics that may predict LVEF recovery after TAVR. Methods: A cohort study was conducted. Consecutive patients undergoing TAVR in our center from January 2012 to December 2020 were included. Baseline clinical profile, electrocardiographic (EKG), echocardiographic (ECH) parameters were recorded, as well as MACE during followup (major adverse cardiovascular events including: all-cause mortality, myocardial infarction, cerebrovascular accident and heart failure hospitalization). Reduced systolic function was defined as LVEF <50%. We considered recovery of systolic function as LVEF ≥50% at follow-up. Results: A total of 292 patients were included. 48% were women and the median age was 81.07 years (77.63-86.22). 22.6% (66 patients) had reduced LVEF at baseline. Half of them showed recovered systolic function during follow-up. Patients who did not recovered LVEF had a higher prevalence of dyslipidemia and peripheral artery disease. History of cardiac surgery was more frequently found in this group, and they showed a higher surgical risk estimated by EuroScore II. They had lower LVEF and aortic valve mean gradient, and more frequently presented non-synus rhythm (NSR), left bundle branch block and right ventricular dysfunction (RVD). These characteristics are shown in figure 1. In univariate analysis lower Euroscore II, presence of synus rhythm, absence of LBBB and RVD, as well as higher aortic valve mean gradient were predictors of LVEF recovery. In multivariate analysis RVD and mean aortic gradient were independent predictors. Among all patients included in our study, those presenting with RV dysfunction were significantly associated with lower LVEF mean values (46,0% vs 57,2%;p<0,01) After a median follow-up of 21.3 (8.52-38.94) months, MACE were lower in recovered LVEF group (HR 0.25 95% CI: 0.05-1.21). There were no statistically significant differences in all-cause mortality, nevertheless there was a trend towards a higher non-cardiovascular mortality in this group, essentially at the expense of deaths from malignant neoplasms and SARS-COV- 2 infections. Survival curves for MACE are represented in figure 2. Conclusion: In our study, half of the patients with impaired ventricular function undergoing TAVR showed recovery of ejection fraction. Right ventricular function and aortic valve mean gradient at baseline were independent predictors of recovery. Identifying predictors of LVEF recovery is fundamental in the evaluation of potential candidates for TAVR, and can help clinicians assess risks and benefits, as well as long-term prognosis of these patients.
