RESUMO
INTRODUCTION: Socioeconomic disparities impact outcomes after cardiac surgery. At our institution, cardiac surgery cases from the safety-net, county funded hospital (CH), which primarily provides care for underserved patients, are performed at the affiliated university hospital. We aimed to investigate the association of socioeconomic factors and CH referral status with outcomes after coronary artery bypass grafting (CABG). METHODS: The institutional Adult Cardiac Surgery database was queried for perioperative and demographic data from patients who underwent isolated CABG between January 2014 and June 2020. The primary outcome was major adverse cardiovascular event (MACE), a composite of postoperative myocardial infarction, stroke, or death. Secondary outcomes included individual complications. Chi-square, Wilcoxon rank-sum, and logistic regression analyses were used to compare differences between CH and non-CH cohorts. RESULTS: We included 836 patients with 472 (56.5%) from CH. Compared to the non-CH cohort, CH patients were younger, more likely to be Hispanic, non-English speaking, and be completely uninsured or require state-specific financial assistance. CH patients were more likely to have a history of tobacco and drug use, liver disease, diabetes, prior myocardial infarction, and greater degrees of left main coronary and left anterior descending artery stenosis. CH cases were less likely to be elective. The incidence of MACE was significantly higher in the CH cohort (16.3% versus 8.2%, P = 0.001). There were no significant differences in 30-d mortality, home discharge, prolonged mechanical ventilation, bleeding, sepsis, pneumonia, new dialysis requirement, cardiac arrest, or multiorgan system failure between cohorts. CH patients were more likely to develop renal failure and less likely to develop atrial fibrillation. On multivariable analysis, CH status (odds ratio 2.39, 95% confidence interval 1.25-4.55, P = 0.008) was independently associated with MACE. CONCLUSIONS: CH patients undergoing CABG presented with greater comorbidity burden, more frequently required nonelective surgery, and are at significantly higher risk of postoperative MACE.

INTRODUCTION: Patients with abdominal aortic aneurysms (AAAs) who are deemed unacceptable candidates for open repair (UNFIT) pose a clinical challenge. The EVAR2 Trial randomized UNFIT patients to endovascular aortic repair (EVAR) vs no intervention from 1999 to 2003, concluding that survival was not improved by EVAR. However, outcomes after EVAR over the last 2 decades have dramatically changed. Thus, the purpose of this study was to evaluate outcomes after EVAR in UNFIT patients using more contemporary data and to determine which subsets of UNFIT patients may potentially benefit from EVAR. METHODS: The Vascular Quality Initiative database (2003-2020) was used to identify elective EVARs for AAAs. Patients were categorized as UNFIT or suitable (SUITABLE) for open repair by the operative surgeon. Predicted 1-year mortality of untreated AAAs was calculated via a modified Gagne Index adjusted for AAA size. The primary outcome for the study was 30-day mortality. Secondary outcomes included perioperative major adverse cardiac events (a composite of clinically significant arrhythmia, congestive heart failure, and myocardial infarction), length of stay, and 1-year mortality. RESULTS: A total of 31,471 patients met study criteria with 27,036 (85.9%) deemed SUITABLE and 4435 (14.1%) UNFIT. UNFIT patients were more likely to experience a perioperative major adverse cardiac event (5.1% vs 2.2%, P < .001) and had longer lengths of stay (1 day [interquartile range, 1-3 days] vs 1 day [interquartile range, 1-2 days], P < .001). The 30-day mortality was significantly higher for UNFIT patients (0.8% vs 0.4%, P < .001). UNFIT patients had worse 1-year survival compared with SUITABLE patients. However, UNFIT and SUITABLE patients had significantly improved actual 1-year mortality with EVAR compared with predicted 1-year mortality without EVAR: 9.5% vs 15.6% (P < .001) and 4.0% vs 11.7% (P < .001), respectively. The mortality benefit after EVAR in UNFIT patients was primarily restricted to those with smaller Gagne Indices and larger aneurysm diameters. Patients deemed unsuitable for open repair due to frailty or multiple reasons had significantly higher 30-day mortality rates after EVAR when compared with SUITABLE patients (1.3% vs 1.6% vs 0.4%, P < .001). Those deemed unsuitable for open repair due to frailty or multiple reasons had worse 1-year cumulative survival compared with all other UNFIT patients. CONCLUSIONS: Despite being high risk with higher perioperative morbidity and mortality, UNFIT patients have lower actual 1-year mortality with EVAR than predicted 1-year mortality without EVAR. However, this potential benefit is reserved to those with small Gagne Indices, larger AAA diameters, and lack of frailty.

PURPOSE: Treatment decisions for the elderly with abdominal aortic aneurysms (AAAs) are challenging. With advancing age, the risk of endovascular aneurysm repair (EVAR) increases while life expectancy decreases, which may nullify the benefit of EVAR. The purpose of this study was to quantify the impact of EVAR on 1-year mortality in patients of advanced age. MATERIALS AND METHODS: The 2003-2020 Vascular Quality Initiative Database was utilized to identify patients who underwent EVAR for AAAs. Patients were included if they were 80 years of age or older. Exclusions included non-elective surgery or missing aortic diameter data. Predicted 1-year mortality of untreated AAAs was calculated based on a validated comorbidity score that predicts 1-year mortality (Gagne Index, excluding the component associated with AAAs) plus the 1-year aneurysm-related mortality without repair. The primary outcome for the study was 1-year mortality. RESULTS: A total of 11 829 patients met study criteria. The median age was 84 years [81, 86] with 9014 (76.2%) being male. Maximal AAA diameters were apportioned as follows: 39.6% were <5.5 cm, 28.6% were 5.5-5.9 cm, 21.3% were 6.0-6.9 cm, and 10.6% were ≥7.0 cm. The predicted 1-year mortality rate without EVAR was 11.9%, which was significantly higher than the actual 1-year mortality rate with EVAR (8.2%; p<0.001). The overall rate of perioperative MACE was 4.4% (n = 516). Patients with an aneurysm diameter <5.5cm had worse actual 1-year mortality rates with EVAR compared to predicted 1-year mortality rates without EVAR. In contrast, those with larger aneurysms (≥5.5cm) had better actual 1-year mortality rates with EVAR. The benefit from EVAR for those with Gagne Indices 2-5 was largely restricted to those with AAAs ≥ 7.0cm; whereas those with Gagne Indices 0-1 experience a survival benefit for AAAs larger than 5.5 cm. CONCLUSION: The current data suggest that EVAR decreases 1-year mortality rates for patients of advanced age compared to non-operative management in the elderly. However, the survival benefit is largely limited to those with Gagne Indices 0-1 with AAAs ≥ 5.5 cm and Gagne Indices 2-5 with AAAs ≥ 7.0 cm. Those of advanced age may benefit from EVAR, but realizing this benefit requires careful patient selection.

BACKGROUND: Cerebrovascular accidents (CVA) are a source of postoperative morbidity. Existing data on CVA after lung transplantation (LT) are limited. We aimed to evaluate the impact of CVA on LT survival. METHODS: A retrospective analysis of LT recipients at the University of Texas Southwestern Medical Center was performed. Data was obtained from the institutional thoracic transplant database between January 2012 and December 2018, which consisted of 476 patients. Patients were stratified by the presence of a postoperative CVA. Univariate comparisons of baseline characteristics, operative variables, and postoperative outcomes between the cohorts were performed. Survival was analyzed by Kaplan-Meier method. Aalen's additive regression model was utilized to assess mortality hazard over time. RESULTS: The incidence of CVA was 4.2% (20/476). Lung allocation score was higher in the CVA cohort (46.2 [41.7, 57.3] vs. 41.5 [35.8, 52.2], p = 0.04). There were no significant differences in operative variables. CVA patients had longer initial intensive care unit (ICU) stays (316 h [251, 557] vs. 124 [85, 218], p < 0.001) and longer length of stay (22 days [17, 53] vs. 15 [11, 26], p = 0.007). CVA patients required more ICU readmissions (35% vs. 15%, p = 0.02) and had a lower rates of home discharge (35% vs. 71%, p < 0.001). Thirty-day mortality was higher in the CVA cohort (20% vs. 1.3%, p < 0.001). Overall survival was lower in the CVA cohort (log rank p = 0.044). CONCLUSIONS: Postoperative CVA following LT was associated with longer ICU stays, more ICU readmissions, longer length of stay, and fewer home discharges. Thirty day and long-term mortality were significantly higher in the CVA group.

BACKGROUND: Adult congenital heart disease (CHD) transplant recipients historically experienced worse survival early after transplantation. We aim to review updated trends in adult CHD transplantation. METHODS: We performed a single center case series of adult cardiac transplants from January 2013 through July 2020. Outcomes of patients with CHD were compared to non-CHD. The primary outcome was overall survival. Secondary outcomes included a variety of post-operative complications. RESULTS: 18/262 (7%) transplants were CHD recipients. CHD patients were younger with median age 41 (32-47) versus 58 (48-65) (P < .001). Fontan circulation for single ventricle physiology was present in 4/18 (22%) of CHD recipients, while 16/18 (89%) had systemic right ventricles. CHD recipients had higher rates of previous cardiovascular operations (94% vs. 51%, P < .001). 9/18 (50%) of CHD patients required reconstructive procedures at the time of transplant. Operative and cardiopulmonary bypass times were longer for the CHD cohort (7.5 h [6.6-8.5] vs. 5.6 h [4.6-7] P < .001) and (197 min [158-240] vs. 130 [105-167] P < .001), respectively. There were no differences in operative complications or survival between CHD and non-CHD recipients. CONCLUSIONS: These data highlight the added technical challenges of performing adult CHD transplants. However, similar outcomes can be achieved as for non-CHD recipients. SUMMARY: Modern advances in palliation of congenital heart defects (CHD) has led to increased survival into adulthood. Many of these patients require heart transplantation as adults. There are limited data on adult CHD transplantation. Historically, these patients have had worse perioperative outcomes with improved long-term survival. We retrospectively analyzed 262 heart transplants at a single center, 18 of which were for adult CHD. Here, we report our series of 18 CHD recipients. We detail the palliative history of all CHD patients and highlight the added technical challenges for each of the 18 patients at transplant. In our analysis, CHD patients had more prior cardiovascular surgeries as well as longer transplant operative and bypass times. Despite this, there were no differences in perioperative and long-term outcomes. We have added patient and institution specific data for transplanting patients with adult CHD. We hope that our experience will add to the growing body of literature on adult CHD transplantation.

BACKGROUND: Cardiopulmonary bypass (CPB) is often used to support patients undergoing lung transplantation who are intolerant of anatomic manipulation or single lung ventilation during the procedure. However, CPB may be associated with adverse outcomes. We evaluated the hypothesis that CPB is associated with increased acute kidney injury (AKI) and postoperative mortality after lung transplantation. MATERIALS AND METHODS: This was a retrospective review of our institutional lung transplant database at the University of Texas Southwestern Medical Center from 2012 to 2018. Patients were grouped based on their need for CPB. The primary outcome was AKI within 48 h of transplantation, which was defined as Kidney Disease Improving Global Outcomes stage 1 or greater. Secondary outcomes included all-cause mortality. RESULTS: A total of 426 patients underwent lung transplantation with 39.0% (n = 166) requiring CPB. There were no differences in demographics and comorbidities, including baseline renal function, between CPB and no CPB. CPB use was higher in recipients with interstitial lung diseases and primary pulmonary hypertension. Median lung allocation score was higher in those needing CPB (47 [interquartile range, 40-59] versus 39 [interquartile range, 35-47]). Patients requiring CPB were significantly more likely to experience AKI (61.44% versus 36.5.3%, P < 0.01) and postoperative hemodialysis (6.6% versus 0.4%, P < 0.01). On multivariable analysis, CPB was significantly associated with postoperative AKI (odds ratio, 1.66; 95% CI, 1.01-2.75; P = 0.04). Thirty-day mortality was higher in patients undergoing CPB (4.2% versus 0.8%, P = 0.03). CONCLUSIONS: CPB for lung transplantation is associated with a higher incidence of AKI, renal failure requiring hemodialysis, and 30-d mortality. CPB should be used selectively for lung transplantation.

BACKGROUND: Necrotizing soft tissue infections (NSTIs) are life-threatening surgical emergencies associated with high morbidity and mortality. Fungal NSTIs are considered rare and have been largely understudied. The purpose of this study was to study the impact of fungal NSTIs and antifungal therapy on mortality after NSTIs. METHODS: A retrospective chart review was performed on patients with NSTIs from 2012 to 2018. Patient baseline characteristics, microbiologic data, antimicrobial therapy, and clinical outcomes were collected. Patients were excluded if they had comfort care before excision. The primary outcome measured was in-hospital mortality. RESULTS: A total of 215 patients met study criteria with a fungal species identified in 29 patients (13.5%). The most prevalent fungal organism was Candida tropicalis (n = 11). Fungal NSTIs were more prevalent in patients taking immunosuppressive medications (17.2% versus 3.2%, P = 0.01). A fungal NSTI was significantly associated with in-hospital mortality (odds ratio, 3.13; 95% confidence interval, 1.16-8.40; P = 0.02). Furthermore, fungal NSTI patients had longer lengths of stay (32 d [interquartile range, 16-53] versus 19 d [interquartile range, 11-31], P < 0.01), more likely to require initiation of renal replacement therapy (24.1% versus 8.6%, P = 0.02), and more likely to require mechanical ventilation (64.5% versus 42.0%, P = 0.02). Initiation of antifungals was associated with a significantly lower rate of in-hospital mortality (6.7% versus 57.1%, P = 0.01). CONCLUSIONS: Fungal NSTIs are more common in patients taking immunosuppressive medications and are significantly associated with in-hospital mortality. Antifungal therapy is associated with decreased in-hospital mortality in those with fungal NSTIs. Consideration should be given to adding antifungals in empiric treatment regimens, especially in those taking immunosuppressive medications.

Atrial fibrillation (AF) is the most prevalent arrhythmia and is often found during times of other cardiac pathologies that require surgical management including coronary revascularization and valve surgery. Surgical ablation of AF, most frequently performed through the Cox-Maze IV procedure, is highly effective in restoring sinus rhythm. Despite robust society guideline recommendations for concomitant surgical ablation (CSA) for AF, the practice has yet to be widely adopted. In this review, we discuss the current indications for CSA, its efficacy in maintaining freedom from atrial tachyarrhythmias, stroke, and adverse long-term outcomes, the safety profile of SA when performed alongside cardiac surgical cases, and challenges with its implementation across the most common concomitant cardiac operations. In conclusion, we present a reminder to multidisciplinary heart teams to consider CSA when indicated for their patients.

BACKGROUND: Cardiopulmonary resuscitation (CPR) is widely used in response to cardiac arrest. However, little is known regarding outcomes for those who undergo multiple episodes of cardiac arrest while in the hospital. OBJECTIVES: The purpose of this study was to evaluate the association of multiple cardiac events with in-hospital mortality for patients admitted to our tertiary care hospital who underwent multiple code events. METHODS: We performed a retrospective cohort study on all patients who underwent cardiac arrest from 2012 to 2016. Primary outcome was survival to discharge. Secondary outcomes included post-cardiac-arrest neurologic events (PCANE), non-home discharge, and one-year mortality. RESULTS: There were 622 patients with an overall mortality rate of 78.0%. Patients undergoing CPR for cardiac arrest once during their admission had lower in-hospital mortality rates compared to those that had multiple (68.9% versus 91.3%, p<.01). Subset analysis of those who had multiple episodes of CPR revealed that more than one event within a 24-hour period led to significantly higher in-hospital mortality rates (94.7% versus 74.4%, p<.01). Other variables associated with in-hospital mortality included body mass index, female sex, malignancy, and increased down time per code. Patients that had a non-home discharge were more likely to have sustained a PCANE than those that were discharged home (31.4% versus 3.9%, p<.01). A non-home discharge was associated with higher one-year mortality rates compared to a home discharge (78.4% versus 54.3%, p=.01). CONCLUSION: Multiple codes within a 24-hour period and the average time per code were associated with in-hospital mortality in cardiac arrest patients.

Coronary artery disease requiring surgical revascularization is prevalent in United States Veterans. We aimed to investigate preoperative predictors of 30-day mortality following coronary artery bypass grafting (CABG) in the Veteran population. The Veterans Affairs Surgical Quality Improvement (VASQIP) national database was queried for isolated CABG cases between 2008 and 2018. The primary outcome was 30-day mortality. A multivariable logistic regression was performed to assess for independent predictors of the primary outcome. A P-value of <0.05 was considered statistically significant. A total of 32,711 patients were included. The 30-day mortality rate was 1.37%. Multivariable analysis identified the following predictors of 30-day mortality: African-American race (OR 1.46, 95% CI 1.09-1.96); homelessness (OR 6.49, 95% CI 3.39-12.45); female sex (OR 2.15, 95% CI 1.08-4.30); preoperative myocardial infarction within 7 days (OR 1.49, 95% CI 1.06-2.10) or more than 7 days before CABG (OR 1.34, 95% CI 1.04-1.72); partially/fully dependent functional status (OR 1.44, 95% CI 1.07-1.93); chronic obstructive pulmonary disease (OR 1.54, 95% CI 1.24-1.92); mild (OR 1.48, 95% CI 1.04-2.11) and severe aortic stenosis (OR 2.06, 95% CI 1.37-3.09); moderate (OR 1.88, 95% CI 1.31-2.72), or severe (OR 2.99, 95% CI 1.71-5.22) mitral regurgitation; cardiomegaly (OR 1.73, 95% CI 1.35-2.22); NYHA Class III/IV heart failure (OR 2.05, 95% CI 1.10-3.83); and urgent/emergent operation (OR 1.42, 95% CI 1.08-1.87). The 30-day mortality rate in US Veterans undergoing isolated CABG between 2008 and 2018 was 1.37%. In addition to established clinical factors, African-American race and homelessness were independent demographic predictors of 30-day mortality.
RESUMO
A woman with a history of congenital heart disease status post multiple valve operations including mitral valve repair presented with 2 months of low back pain and general malaise. Blood cultures returned positive for Gram-positive cocci. While transthoracic echocardiography did not identify vegetations, transoesophageal echocardiography visualised vegetations on the patient's mitral valve, which had previously undergone repair with annuloplasty. The patient was found to have infectious endocarditis (IE), caused by Gemella morbillorum The patient was treated with over 6 weeks of intravenous antibiotics. Cases of Gemella-associated IE are rare and largely relegated to case reports. This report aims to contribute to the literature regarding this subject, and to further characterise the presentation and treatment of Gemella-associated IE. Additionally, this report emphasises the importance of maintaining a high suspicion of IE in a patient with non-specific malaise in the setting of prior cardiac valve operation.

BACKGROUND: Esophagectomies are known to be technically challenging operations that create significant physiologic changes. These patients often require assisted care postoperatively that necessitates a nonhome discharge. The purpose of this study was to assess factors associated with nonhome discharge after esophagectomy for neoplastic disease. METHODS: The 2016 to 2017 American College of Surgeons National Surgical Quality Improvement Program Esophagectomy database was queried to identify patients who underwent esophagectomy for a neoplasm. Patients were excluded if they died within 30 days of their operation, the index operation was considered emergent, or had missing data for the variables of interest. Multivariable analysis was performed to identify which factors were predictive of nonhome discharge. RESULTS: One thousand seven patients were included. Of those, 121 (12.0%) had a nonhome discharge. Multivariable analysis showed that the following factors were associated with nonhome discharge: Modified Charlson comorbidity index (adjusted odds ratio [aOR], 2.04; 95% confidence interval [CI], 1.49-2.86), partially dependent preoperative functional status (aOR, 13.18; 95% CI, 1.07-315.67), urinary tract infection (aOR, 5.25; 95% CI, 1.32-20.41), and length of stay (aOR, 1.12; 95% CI, 1.08-1.16). CONCLUSIONS: We identified various factors associated with nonhome discharge. Early identification of patients who are at risk for nonhome discharge is important for early discharge planning, which may decrease nonmedical delays and healthcare costs.

Colorectal cancer (CRC) is the third most common malignancy and the second most common cause of cancer-related mortality worldwide. A total of 20% of CRC patients present with distant metastases, most frequently to the liver and lung. In the primary tumor, as well as at each metastatic site, the cellular components of the tumor microenvironment (TME) contribute to tumor engraftment and metastasis. These include immune cells (macrophages, neutrophils, T lymphocytes, and dendritic cells) and stromal cells (cancer-associated fibroblasts and endothelial cells). In this review, we highlight how the TME influences tumor progression and invasion at the primary site and its function in fostering metastatic niches in the liver and lungs. We also discuss emerging clinical strategies to target the CRC TME.
