RESUMEN
Background: Patients undergoing cardiothoracic surgery frequently encounter perioperative neurocognitive disorders (PND), which can include postoperative delirium (POD) and postoperative cognitive decline (POCD). Currently, there is not enough evidence to support the use of electroencephalograms (EEGs) in preventing POD and POCD among cardiothoracic surgery patients. This meta-analysis examined the importance of EEG monitoring in POD and POCD. Methods: Cochrane Library, PubMed, and EMBASE databases were searched to obtain the relevant literature. This analysis identified trials based on the inclusion and exclusion criteria. The Cochrane tool was used to evaluate the methodological quality of the included studies. Review Manager software (version 5.3) was applied to analyze the data. Results: Four randomized controlled trials (RCTs) were included in this meta-analysis, with 1096 participants. Our results found no correlation between EEG monitoring and lower POD risk (relative risk (RR): 0.81; 95% CI: 0.55-1.18; p = 0.270). There was also no statistically significant difference between the EEG group and the control group in the red cell transfusions (RR: 0.86; 95% CI: 0.51-1.46; p = 0.590), intensive care unit (ICU) stay (mean deviation (MD): -0.46; 95% CI: -1.53-0.62; p = 0.410), hospital stay (MD: -0.27; 95% CI: -2.00-1.47; p = 0.760), and mortality (RR: 0.33; 95% CI: 0.03-3.59; p = 0.360). Only one trial reported an incidence of POCD, meaning we did not conduct data analysis on POCD risk. Conclusions: This meta-analysis did not find evidence supporting EEG monitoring as a potential method to reduce POD incidence in cardiothoracic surgery patients. In the future, more high-quality RCTs with larger sample sizes are needed to validate the relationship between EEG monitoring and POD/POCD further.
RESUMEN
BACKGROUND: The College of Surgeons of East, Central, and Southern Africa (COSECSA) comprises 14 countries, many of which currently grapple with an increasing burden of cardiothoracic surgical (CTS) diseases. Health and economic implications of unaddressed CTS conditions are profound and require a robust regional response. This study aimed to define the status of CTS specialist training in the region (including the density of specialists, facilities, and active training posts), examine implications, and proffer recommendations. METHODS: A desk review of COSECSA secretariat documents and program accreditation records triangulated with information from surgical societies was performed in May 2022 and September 2023 as part of education quality improvement. A modified nominal group process involving contextual experts was used to develop a relevant action framework. RESULTS: Only 6 of 14 (43%) of COSECSA countries offered active training programs with annual intake of only 18 trainees. Significant training gaps existed in Burundi, Botswana, Malawi, Rwanda, South Sudan, Zambia, and Zimbabwe. Country specialist density ranged from 1 per 400,000 (Namibia) to 1 per 8,000,000 (Ethiopia). Overall, the region had 0.2 CTS specialists per million population as compared with 7.15 surgeons per million in High-Income Countries. Surgical education experts proposed an action framework to address the training crisis including increasing investments in CTS education, establishing regional centers of excellence, retention incentives and opportunities for women, and leveraging international partnerships. CONCLUSION: Proactive investments in infrastructure, human resources, training, and collaborative efforts by national governments, regional intergovernmental organizations, and international partners are critical to expanding regional CTS training.
RESUMEN
Objective. To evaluate patient characteristics and 5-year outcomes after surgical mitral valve (MV) repair for leaflet prolapse at a medium-sized cardiothoracic center. Background. Contemporary reports on the outcome of MV repair at medium-sized cardiothoracic centers are sparse. Methods. Patients receiving open-heart surgery with MV repair due to primary mitral regurgitation caused by leaflet prolapse between 2015 and 2021, without active endocarditis, were included. Clinical data, complications, re-interventions, mortality, and echocardiographic data were retrospectively registered from electronical patient charts, both pre-operatively and from post-operative follow-ups. Results. One hundred and three patients were included, 83% male, with a mean age of 62 years. All-cause mortality was 9% during a median follow-up time of 4.9 years. Re-intervention rate on the MV was 4%. Post-operative complications before last available follow-up visit at median 3.0 years were infrequent, with new-onset atrial fibrillation/flutter in 16%, post-operative MV regurgitation grade II or above in 17% and post-operative tricuspid regurgitation grade II or above in 14%. Conclusions. These data demonstrate that surgical MV repair for leaflet prolapse at a medium-sized cardiothoracic center was associated with low re-intervention rate and few severe complications. The presented results are comparable to data from surgical high-volume centers, indicating that surgical MV repair can be safely performed at selected medium-sized cardiothoracic centers.

PURPOSE OF REVIEW: The purpose of this review is to synthesize and examine the literature on the use of neuraxial anesthesia and analgesia during cardiothoracic surgery. As cardiothoracic procedures often require systemic anticoagulation, neuraxial techniques are quite often underutilized due to the theoretical risk of epidural hematoma. In this review, we seek to examine the literature to review the indications and contraindications and to explore if neuraxial anesthesia and analgesia has a role in cardiothoracic surgery. RECENT FINDINGS: Neuraxial techniques have multiple advantages during cardiothoracic surgery including coronary vasodilation, decreased sympathetic surge, and a decreased cortisol level leading to overall reduction in stress response. Multiple studies have shown an improvement in pain scores, reduction in pulmonary complications, faster extubation times, with minimal complications when neuraxial techniques are utilized in cardiothoracic surgeries. Given the numerous advantages and minimal complications of neuraxial techniques in cardiothoracic surgeries, we hope its utilization continues to increase. Moving forward, we hope additional studies continue to reaffirm the benefits of neuraxial anesthesia and analgesia for cardiothoracic surgeries to improve its utilization.

Implementation science is a nascent field that aims to study the factors that influence the effectiveness of a given clinical intervention, such as the characteristics of the individuals involved, the internal and external settings, the process of implementation, and other factors. Overall, implementation science aims to increase the extent to which an intervention is practiced, and the quality of its delivery to a patient. Although still in its infancy, the applications of implementation science in anesthesiology and cardiothoracic surgery abound. Whether used to adopt novel innovations, avoid the use of obsolete practices, or redeploy existing interventions to improve quality, implementation science holds promise in optimizing how we bring the latest in clinical science to produce tangible benefits to patients and create sustainable change.

Cardiopulmonary bypass and extracorporeal membrane oxygenation have many similarities, but there are significant differences in managing hemostasis. Cardiopulmonary bypass includes shorter mechanical circulatory support times, blood stasis, higher flows, and an increased blood-air interface. These factors cause differences in the risk of coagulopathy, management of anticoagulation, monitoring of the hemostatic system, and management of coagulopathy. This article aims to identify these key differences in the hemostatic system between patients on cardiopulmonary bypass and those on extracorporeal membrane oxygenation.
RESUMEN
Hypertension after cardiothoracic surgery is common, often requiring pharmacologic management. The recommended first-line antihypertensives in pediatrics are angiotensin converting enzyme inhibitors. Captopril and enalapril are approved for infants and children; however, lisinopril is only approved for > 7 years of age. This study evaluated safety and efficacy of converting from captopril to lisinopril in patients utilizing a pre-defined conversion of 3 mg captopril to 1 mg lisinopril. This was a single center, retrospective study including patients less than 7 years of age admitted for cardiothoracic surgery who received both captopril and lisinopril from 01/01/2017 to 06/01/2022.The primary outcome was mean change in systolic blood pressure (SBP) from baseline for 72 h after conversion of captopril to lisinopril. A total of 99 patients were enrolled. There was a significant decrease in mean SBP (99.12 mmHg vs 94.86 mmHg; p = 0.007) with no difference in DBP (59.23 mmHg vs 61.95 mmHg; p = 0.07) after conversion to lisinopril. Of the 99 patients who were transitioned to lisinopril, 79 (80%) had controlled SBP, 20 (20%) remained hypertensive, 13 (13%) received an increase in their lisinopril dose, and 2 (2%) required an additional antihypertensive agent. There was a low overall rate of AKI (3%) and hyperkalemia (4%) respectively. This study demonstrates that utilizing lisinopril with a conversion rate of 3 mg of captopril to 1 mg of lisinopril was safe and effective for controlling hypertension in pediatric patients following cardiothoracic surgery.

Recent studies have suggested worse outcomes in patients exposed to hyperoxia while supported on veno-arterial extracorporeal membrane oxygenation (VA-ECMO). However, there are no data regarding the effect of reducing hyperoxia exposure in this population by adjusting the fraction of inspired oxygen (FiO2) of the sweep gas of the ECMO circuit. A retrospective review of 143 patients less than 1 year of age requiring VA-ECMO following cardiac surgery from 2007 to 2018 was completed. 64 patients had a FiO2 of the sweep gas < 100% with an average PaO2 of 210 mm Hg in the first 48 h of support [vs 405 mm Hg in the group with a FiO2 = 100% (p < 0.0001)]. There was no difference in mortality at 30 days after surgery or other markers of end-organ injury with respect to whether the FiO2 was adjusted. At least one PaO2 value < 200 mm Hg in the first 24 h on ECMO in patients with a FiO2 < 100% trended toward a significant association (OR = 0.45, 95% CI = 0.21-1.01) with decreased risk of 30-day mortality when compared to those patients with a FiO2 = 100% and all PaO2 values > 200 mm Hg. Only 47% of patients with a FiO2 < 100% had an average PaO2 less than 200 mm Hg which indicates that the intervention of reducing the FiO2 of the sweep gas was not entirely effective at reducing hyperoxia exposure. Future research is needed for developing clinical protocols to avoid hyperoxia and to identify mechanisms for hyperoxia-induced injury on VA-ECMO.

INTRODUCTION: CHD is a unique group of medical pathologies. Literature worldwide reports significant decrements in the case volume of patients with these conditions due to the recent global pandemic of coronavirus disease 2019. The only centre providing congenital cardiac care for Lithuanian population is in a hospital which was the main medical institution for the sickest coronavirus disease 2019 patients. Hence, this centre had to maintain its service alongside the mobilisation of resources to tackle the crisis. AIM OF STUDY: To evaluate the effect of the pandemic on the service of congenital heart surgery in Lithuania. METHODS: The activity of a single centre providing congenital heart care working in a main coronavirus 2019 pandemic hospital during the pandemic was analysed and compared to a matched period of pre-pandemic activity. RESULTS: The number of admitted patients was similar during both pre-pandemic and pandemic periods. During the pandemic period, younger patients were more often operated as urgent cases. Their postoperative length of stay was longer. However, there were no differences in early postoperative mortality between the two groups. CONCLUSIONS: It was possible to maintain an accessible and high-quality specialised congenital cardiac care for various age patients during global pandemic events, while working in the main pandemic hospital.
RESUMEN
OBJECTIVES: Cardiothoracic surgery has reported poor equality, diversity, and inclusion amongst its faculty [1-3]. We explored how gender, ethnicity, and disability influence medical students' interest in cardiothoracic surgery as a career choice, as well as overall exposure to cardiothoracic surgery in the undergraduate curriculum. METHODS: We distributed a 26-item Google Forms online survey to student members of a medical education group from all 37 UK medical schools via social media. Respondents were asked to rank different 'factors of interest' on a 1-5 Likert scale (1 â= ânot important at all, 5 â= âvery important) and were encouraged to add free-text comments. Quantitative data were analysed using SPSS. RESULTS: There were 258 respondents, 62% identifying as female and 38% male. Respondents' ethnicities were 45% White, 44% Asian or Asian British, and 11% from other ethnic groups. 11% of respondents confirmed 'long-standing illness or disability'. Men were almost twice as likely to consider a career in cardiothoracic surgery than women (33% vs 19%; p â< â0.001). Women were more likely than men to feel that their gender, lack of a similarly gendered mentor, and long working hours were important factors when considering cardiothoracic surgery as a career. Ethnicity of the respondent did not appear to affect how they perceived the challenges of a career in cardiothoracic surgery. Interestingly, 'long-standing illness or disability' did not significantly affect the decision making to consider this specialty as a career. Overall, 73% of respondents reported not having adequate exposure to cardiothoracic surgery at medical school and agreed they would benefit from more time. CONCLUSIONS: Female medical students felt their gender, lack of same-sex role models, and perceived long working hours were barriers in considering cardiothoracic surgery as a career. All students felt the need for more exposure to Cardiothoracic Surgery in the undergraduate curriculum.
RESUMEN
Background: Nitric Oxide (NO) is a naturally occurring modulator of inflammation found in the human body. Several studies in the pediatric cardiothoracic surgery literature have demonstrated some beneficial clinical effects when NO is added to the sweep gas of the cardiopulmonary bypass circuit.Purpose: Our primary aim was to determine the safety of incorporating nitric oxide into the oxygenator sweep gas of the extracorporeal membrane oxygenation (ECMO) circuit. Secondarily, we looked at important clinical outcomes, such as survival, blood product utilization, and common complications related to ECMO.Methods: We performed a single center, retrospective review of all patients at our institution who received ECMO between January 1, 2017 and March 31, 2023. We began additing NO to the ECMO sweep gas in 2019. Results: There were no instances of clinically significant methemoglobinemia with the addition of NO to the sweep gas (0% vs 0%, p = 1). The median daily methemoglobin level was higher in those who received NO via the sweep gas when compared to those who did not (1.6 vs 1.1, p = <0.001). Conclusions: The addition of NO to the sweep gas of the ECMO circuit is safe.
RESUMEN
INTRODUCTION: Over the past decade, there has been an increase in the use of recombinant Anti-Thrombin III (AT-III) administration during neonatal and pediatric short- and long-term mechanical support for the replacement of acquired deficiencies. Recombinant AT-III (Thrombate) administration is an FDA licensed drug indicated primarily for patients with hereditary deficiency to treat and prevent thromboembolism and secondarily to prevent peri-operative and peri-partum thromboembolism. Herein we propose further use of Thrombate for primary AT-III deficiency of the newborn as well as for acquired dilution and consumption secondary to cardiopulmonary bypass (CPB). METHODOLOGY: All patients undergoing CPB obtain a preoperative AT-III level. Patients with identified deficiencies are normalized in the OR using recombinant AT-III as a patient load, in the CPB prime, or both. Patient baseline Heparin Dose Response (HDR) is assessed using the Heparin Management System (HMS) before being exposed to AT-III. If a patient load of AT-III is given, a second HDR is obtained and this AT-III Corrected HDR is used as the primary goal during CPB. Once CPB is initiated, an AT-III level is obtained with the first patient blood analysis. A subtherapeutic level results in an additional dose of AT-III. During the rewarm period, a final AT-III level is obtained and AT-III treated once again if subtherapeutic. A retrospective, matched analysis review of practice analyzing two groups, a Study Group (Repeat HDR, May 2022 onward) and Matched Group (Without Repeat HDR, July 2019 to April 2022), for age (D), weight (Kg) and operation was conducted. The focus of the study was to determine any change in heparin sensitivity identified post AT-III patient bolus load in the HDR (U/mL), Slope (U/mL/s), ACT (s), and total amount of heparin on CPB (U) and protamine (mg) used in each group. RESULTS: No significance was seen in Baseline AT-III (%), post heparin load HDR (U/mL), first CPB ACT (s), first CPB HDR (U/mL), or total CPB heparin (u/Kg) between the two groups. Statistical significance was seen in Baseline ACT (s), Baseline HDR (U/mL), Baseline Slope (U/mL/s), Post Heparin Load ACT (s), first CPB AT-III (%), and Protamine (mg/Kg) (p < .05). No statistical significance was seen in the Study Intragroup between pre versus post AT-III patient load baseline sample in ACT (s), however significance was seen in HDR (U/mL) and Slope (U/mL/s) (p < .05). CONCLUSION: Implementation of AT-III monitoring and therapy before and during CPB in conjunction with the HMS allows patients to maintain a steady state of anticoagulation with overall less need for excessive heparin replacement and potentially thrombin activation. The result is obtaining a steady state of anticoagulation, a reduced fluctuation in the heparin and ACT levels and a potential for lower co-morbidities associated with prolonged CPB times.
RESUMEN
INTRODUCTION: For Jehovah's Witness (JW) patients requiring cardiac surgery, various strategies such as preoperative use of erythropoietin stimulating agents (ESAs), intravenous iron (IVI), and non-pharmacologic interventions have emerged to prevent complications from blood loss given transfusion is not acceptable in this population. METHODS: Retrospective case-control of cardiac surgeries performed by the same surgeon between 1/1/2011 and 8/30/2021. JW patients were matched to non-JW who received blood products and non-JW who did not receive blood products on a 1:2:2 basis. Patients were matched on procedure, age, gender, and Society of Thoracic Surgeons morbidity score. Eligible patients were aged >18 years and had a sternotomy procedure. The primary efficacy and safety outcomes included mean hematocrit values perioperatively and thrombotic events. RESULTS: A total of 27 JW, 52 non-JW transfused, and 53 non-JW not transfused patients were included in the analysis. JW patients had significantly higher mean hematocrits at every time point when compared to non-JW transfused patients and at all time points except clinic and the last recorded operating room value when compared to non-JW not transfused patients. No significant differences in thrombotic rates were found between groups, however there was a numerically higher incidence in the JW population (JW: 7.4%; non-JW transfused: 0%; non-JW not transfused: 1.9%; p = .106). CONCLUSION: A blood conservation protocol in a JW population was associated with higher perioperative hematocrit values when compared to matched controls. Further prospective study is warranted before applying similar protocols to other populations given the possibility for an increased rate of venous thromboembolism.
RESUMEN
BACKGROUND: Treatment for infective endocarditis (IE) is usually medical, with surgery reserved for those failing medical management or developing complications. Currently, 25%-50% of patients undergo surgery for IE with a 70%-80% immediate survival rate. However, there is controversy over the timing of surgery following cerebrovascular events, which occur in 15%-30% of IE patients. This study aimed to investigate whether surgical management is superior to medical management in patients with IE and to determine the optimal timing for surgery following the development of neurological symptoms. METHODS: Data were collected retrospectively between 2012 and 2018 from 436 patients diagnosed with IE and treated at our tertiary teaching hospital. The authors analysed the type of treatment, the timing of surgery, and the outcomes of these including mortality, IE recurrence, and length of hospital stay. RESULTS: A total of 421 patients were included in the analysis. More than two-thirds (69.1%) of patients underwent surgical intervention. The survival rate of patients having surgery for IE was 77.2%, compared to 50.7% in patients who did not undergo surgical intervention. 6.8% of patients presented with neurological symptoms; 73.3% of these patients had surgery within 14 days with a 90.9% survival. CONCLUSION: This study finds surgery to be safe with a seemingly higher survival rate compared to medical management alone, although this may be confounded by patients in the medical group being less likely to have surgery. Surgery in patients presenting with neurological symptoms is safe within 2 weeks from presentation with excellent outcomes.
RESUMEN
The aim of this study is to systematically evaluate the effects of quality nursing on wound infections and postoperative complications in patients undergoing cardiothoracic surgery. Computerised searches of the PubMed, Web of Science, Cochrane Library, Embase, China Biomedical Literature Database, China National Knowledge Infrastructure and Wanfang databases were conducted from database inception to October 2023 for randomised controlled trials (RCTs) on the application of quality nursing to patients undergoing cardiothoracic surgery. The studies were screened and evaluated by two researchers based on the inclusion and exclusion criteria, and data were extracted from the included studies. Stata software (version 17.0) was used for all analyses performed. A total of 18 RCTs and 1742 patients were included, including 972 in the quality nursing group and 870 in the routine nursing group. The analysis revealed that compared with routine nursing, patients undergoing cardiothoracic surgery who received quality nursing care were significantly less likely to experience postoperative wound infections (OR = 0.31, 95% CI: 0.19-0.51, p < 0.001) and complications (OR = 0.24. 95% CI: 0.17-0.33, p < 0.001). The implementation of quality nursing in clinical care after cardiothoracic surgery can effectively reduce the incidence of wound infections and postoperative complications, and is worthy of promotion and clinical application.

Surgical site infections (SSIs) following cardiothoracic surgery can pose significant challenges to patient recovery and outcome. This systematic review and meta-analysis aim to identify and quantify the risk factors associated with SSIs in patients undergoing cardiothoracic surgery. A comprehensive literature search adhering to Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines and based on the PICO paradigm was conducted across four databases: PubMed, Embase, Web of Science and the Cochrane Library, without any temporal restrictions. The meta-analysis incorporated studies detailing the risk factors for post-operative sternal infections, especially those reporting odds ratios (OR) or relative risks with 95% confidence intervals (CI). Quality assessment of the studies was done using the Newcastle-Ottawa Scale. Statistical analysis was executed using the chi-square tests for inter-study heterogeneity, with further analyses depending on I2 values. Sensitivity analyses were performed, and potential publication bias was also assessed. An initial dataset of 2442 articles was refined to 21 articles after thorough evaluations based on inclusion and exclusion criteria. Patients with diabetes mellitus have an OR of 1.80 (95% CI: 1.40-2.20) for the incidence of SSIs, while obese patients demonstrate an OR of 1.63 (95% CI: 1.40-1.87). Individuals who undergo intraoperative blood transfusion present an OR of 1.13 (95% CI: 1.07-1.18), and smokers manifest an OR of 1.32 (95% CI: 1.03-1.60). These findings unequivocally indicate a pronounced association between these factors and an elevated risk of SSIs post-operatively. This meta-analysis confirms that diabetes, obesity, intraoperative transfusion and smoking heighten the risk of SSIs post-cardiac surgery. Clinicians should be alert to these factors to optimise patient outcomes.

Surgical site infections (SSIs) post-cardiothoracic surgery represent a significant challenge in patient care. Understanding the risk factors contributing to SSIs is essential for improving surgical outcomes and patient safety. A comprehensive retrospective analysis was conducted at our institution from January 2021 to December 2022. This study included 30 patients with SSIs and 60 without, following cardiothoracic open surgery. Data were collected on various variables, including hypertension, anaemia, operation time, hospital stay, alcohol consumption, smoking habits, Body Mass Index, age, and drainage tube placement. Univariate and multivariate logistic regression analyses were employed using SPSS software to identify significant predictors of SSIs. Univariate analysis indicated a strong correlation between SSIs and factors like smoking, diabetes mellitus, drainage tube placement, anaemia, and significant intraoperative blood loss (≥800 mL). These factors were statistically significant with p-values < 0.05. Multivariate logistic regression further confirmed the impact of these factors, with high odds ratios indicating a substantial increase in SSI risk associated with these conditions. This study highlights intraoperative blood loss, anaemia, drainage tube placement, smoking, and diabetes mellitus as key risk factors for SSIs post-cardiothoracic surgery. Recognising and addressing these factors through targeted preventive measures is crucial in clinical practice to reduce the incidence of SSIs and improve postoperative care in cardiothoracic surgery.

Background: The benefits of utilizing internal thoracic arteries (ITAs) in coronary bypass surgery are well-known. However, the safety of this practice in elderly patients needs to be proven. Methods: We studied all patients who are 75 years of age and older, who received at least one ITA graft while undergoing isolated, conventional (median sternotomy) coronary artery bypass graft surgery (CABG) between Jan 1st 2002 and Dec 31st 2020 (19 years). Emergent surgeries were excluded. Propensity score matching was used to reduce the patient selection effect. Study outcomes were 30-days mortality, and two sets of dependent intraoperative parameters and postoperative parameters. Results: A total of 1855 patients undergoing CABG was included, of which 1114 received a single left (s)ITA and 741 received combined left and right (d)ITA grafts. 519 pairs were matched. The decision for sITA or dITA was made individually. Thirty-days mortality was low and similar in both groups (sITA 3.3%; dITA 2.9%, p = 0.859). The incidence of sternal wound healing disorder was higher after dITA (3.3 vs 6.9%; p < 0.011), which had also a longer skin-to-skin operative time (181 vs 205 min; p < 0.0001). Re-thoracotomy rates were similar (4.6 vs 6.2%; p = 0.340). There were no significant differences in other secondary parameters. Conclusions: harvesting both ITAs in elderly patients is safe and feasible. However, it increases the risk of sternal wound healing disorders. Long term benefit still needs to be proven.
RESUMEN
BACKGROUND: Impella 5.5 (Abiomed; Danvers, MA) (IMP5) is a commonly used, surgically implanted, tMCS device that requires systemic anticoagulation and purge solution to avoid pump failure. To avoid heparin-induced thrombocytopenia (HIT) from unfractionated heparin (UFH) use, our program has explored the utility of bivalirudin (BIV) for systemic anticoagulation and sodium bicarbonate-dextrose purge solution (SBPS) in IMP5.5. METHODS: This single center, retrospective study included 34 patients supported on IMP5.5 with BIV based AC and SBPS between December 1st 2020 to December 1st 2021.The efficacy and safety end points were incidence of development of HIT, Tissue Plasminogen Activator (tPA) use for suspected pump thrombosis, stroke, and device failure as well as clinically significant bleeding. RESULTS: The median duration of IMP5.5 support was 9.8 days (IQR: 6-15). Most patients were bridged to HTX (58%) followed by recovery (27%) and LVAD implantation (15%). Patients were therapeutic on bivalirudin for 64% of their IMP5.5 support. One patient (2.9%) suffered from ischemic stroke and 26.5% (9) patients developed clinically significant bleeding. tPA was administered to 7(21%) patients. One patient in the entire cohort developed HIT. CONCLUSIONS: Our experience supports the use of systemic BIV and SBPS as a method to avoid heparin exposure in a patient population predisposed to the development of HIT.

OBJECTIVES: To evaluate sodium-glucose cotransporter 2 inhibitors (SGLT2i) use and complications (euglycemic diabetic ketoacidosis [eDKA] rate, mortality, infection, hospital, and cardiovascular intensive care unit [CVICU] length of stay [LOS]) in patients undergoing cardiac surgery. DESIGN: A retrospective study. SETTING: At an academic university hospital. PARTICIPANTS: Adult patients undergoing cardiac surgery. INTERVENTIONS: SGLT2i use versus no SGLT2i use. MEASUREMENTS AND MAIN RESULTS: The authors evaluated patients undergoing cardiac surgery within 24 hours of hospital admission (between February 2, 2019 to May 26, 2022) for SGLT2i prevalence and eDKA frequency. The outcomes were compared using Wilcoxon rank sum and chi-square testing as appropriate. The cohort included 1,654 patients undergoing cardiac surgery, of whom 53 (3.2%) were prescribed an SGLT2i before surgery; 8 (15.1%) of 53 had eDKA. The authors found no differences between patients with and without SGLT2i use in hospital LOS (median [IQR]: 4.5 [3.5-6.3] v 4.4 [3.4-5.6] days, p = 0.46) or CVICU LOS (median [IQR]: 1.2 [1.0-2.2] v 1.1 [1.0-1.9] days, p = 0.22), 30-day mortality (1.9% v 0.7%, p = 0.31), or sternal infections (0.0% v 0.3%, p = 0.69). Among patients prescribed an SGLT2i, those with and without eDKA had similar hospital LOS (5.1 [4.0-5.8] v 4.4 [3.4-6.3], p = 0.76); however, CVICU LOS was longer in patients with eDKA (2.2 [1.5-2.9] v 1.2 [0.9-2.0], p = 0.042). Mortality (0.0% v 2.2%, p = 0.67) and wound infections (0.0% v 0.0%, p > 0.99) were similarly rare. CONCLUSIONS: Postoperative eDKA occurred in 15% of patients on an SGLT2i prior to cardiac surgery, and was associated with longer CVICU LOS. Future studies into SGLT2i management perioperatively are important.
