Thoracic aortic infection (TAI), including infections of the native aorta, prosthetic graft infections, aortoesophageal fistula, and aortobronchial fistula, remains among the most challenging and fatal diseases. This study aimed to review our 25-year experience with surgical management of TAI.
Methods
This retrospective study included 106 participants with TAI from January 2000 to September 2024. The primary end point was hospital mortality. Secondary end points included 30-day mortality, trends in TAI management, overall survival, freedom from infection-related death, and freedom from infection-related events. Subgroup analyses were also conducted. The current surgical strategy has been in use since 2008.
Results
Among 106 participants, 33 (31.1%) had aortoesophageal fistula, 7 (6.6%) had aortobronchial fistula, and 66 (62.2%) had TAI without fistula. Eighty-four participants underwent surgery after 2008. In situ replacement was performed in 85 (80.1%), thoracic endovascular aortic repair in 15 (14.1%), and extra-anatomical bypass in 6 (6%). The 30-day mortality rate was 3.7% (n = 4), and hospital mortality was 16.0% (n = 17). At 10 years, overall survival was 55.4% ± 5.9%, freedom from infection-related death was 78.7% ± 4.3%, and freedom from infection-related events was 76.1% ± 4.4%. Participants who underwent surgery after 2008 had significantly better outcomes than those treated before 2008.
Conclusions
Despite the continued high hospital mortality associated with surgical treatment of TAI, the strategy implemented since 2008 has resulted in improved outcomes. The long-term outcomes were acceptable.

Objectives
The study objectives were to analyze trends in bilateral internal thoracic artery grafting during isolated coronary artery bypass grafting over a 35-year interval and compare outcomes between bilateral internal thoracic artery and non–bilateral internal thoracic artery strategies.
Methods
A cohort of 15,991 patients underwent isolated multivessel coronary artery bypass grafting at our institution between 1990 and 2024. Trends in bilateral internal thoracic artery, radial artery, and left internal thoracic artery + saphenous vein graft were assessed using chi-square tests with Bonferroni correction. Changes in obesity and diabetes prevalence across intervals were also analyzed. Propensity score matching (1:1) yielded 2013 pairs for outcome comparisons between bilateral internal thoracic artery and non–bilateral internal thoracic artery groups.
Results
Between 1990 and 2024, use of bilateral internal thoracic artery and radial artery increased (11.0% and 13.2%, respectively), although bilateral internal thoracic artery declined during 2020 to 2024 as radial artery and left internal thoracic artery + saphenous vein graft use increased. This decline was unrelated to rising obesity or diabetes rates. Matched analysis revealed longer operative times for bilateral internal thoracic artery (+51 minutes, P < .001), whereas cardiopulmonary bypass and crossclamp durations remained similar. Wound-healing complication rates did not increase with bilateral internal thoracic artery grafting. Kaplan–Meier analysis showed superior 30-year survival for bilateral internal thoracic artery compared with other grafting strategies.
Conclusions
Bilateral internal thoracic artery grafting remains underused, particularly in recent years, despite demonstrated survival benefits and comparable wound-healing risks. The decline is not explained by patient risk factors, highlighting the need for broader adoption of bilateral internal thoracic artery grafting and further randomized trials to optimize coronary artery bypass grafting strategies.

Objective
Laboratory abnormalities related to hepatic function are common after cardiac surgery and may reflect transient physiologic stress or early organ dysfunction. This study aimed to evaluate how postoperative liver-related laboratory abnormalities inform prognosis for 30-day mortality after adult cardiac surgery.
Methods
This retrospective cohort study analyzed 16,236 adults undergoing coronary artery bypass grafting or left-sided valve surgery between 2010 and 2022 at a single institution. Receiver operating characteristic analysis was conducted to assess discriminatory performance of laboratory values for 30-day mortality. Peak postoperative aspartate aminotransferase, total bilirubin, and lactate were analyzed as markers of hepatic dysfunction. Patients were stratified by combinations of laboratory abnormalities and timing of peak elevation. Unadjusted logistic regression was used to generate probability plots illustrating the relationship between peak laboratory values and mortality. Multivariable logistic regression adjusted for postoperative complications.
Results
Aspartate aminotransferase and lactate (area under the curve = 0.85) demonstrated the highest discrimination for 30-day mortality. Aspartate aminotransferase remained independently associated with mortality after multivariable adjustment (odds ratio, 1.03 per 100 U/L, P < .001). Isolated laboratory elevations were not associated with substantial mortality risk. However, patients with concurrent elevations in aspartate aminotransferase, total bilirubin, and lactate experienced significantly greater (25.5% vs 1.2%, P < .001) 30-day mortality compared with those with no abnormalities. Mortality was significantly higher when laboratory abnormalities persisted more than 48 hours postoperatively.
Conclusions
Postoperative elevations in liver-related laboratory values—particularly when occurring in combination or peaking beyond 48 hours after surgery—identify patients at markedly increased risk of 30-day mortality. These markers provide valuable insight into physiologic stress and should be carefully managed after cardiac surgery.
目的心脏手术后肝功能相关的实验室异常很常见,可能反映了短暂的生理应激或早期器官功能障碍。本研究旨在评估成人心脏手术后肝脏相关实验室异常对30天死亡率预后的影响。方法本回顾性队列研究分析了2010年至2022年在同一机构接受冠状动脉搭桥术或左侧瓣膜手术的16,236名成年人。进行受试者工作特征分析,以评估30天死亡率实验室值的歧视性表现。术后峰值天冬氨酸转氨酶、总胆红素和乳酸作为肝功能障碍的标志物进行分析。根据实验室异常和峰值升高时间对患者进行分层。使用未经调整的逻辑回归生成概率图,说明峰值实验室值与死亡率之间的关系。多变量logistic回归校正术后并发症。结果天冬氨酸转氨酶和乳酸(曲线下面积= 0.85)对30天死亡率的判别性最高。多变量调整后,天冬氨酸转氨酶仍然与死亡率独立相关(优势比为1.03 / 100 U/L, P < 0.001)。孤立的实验室升高与大量死亡风险无关。然而,与未出现异常的患者相比,伴有天冬氨酸转氨酶、总胆红素和乳酸水平升高的患者30天死亡率明显更高(25.5% vs 1.2%, P < 0.001)。术后48小时实验室检查异常,死亡率明显增高。结论:术后肝脏相关实验室值升高,特别是合并出现或术后48小时后达到峰值时,可识别30天死亡风险显著增加的患者。这些指标提供了有价值的洞察生理应激和应小心处理心脏手术后。

Objective
Kommerell diverticulum is an embryologic remnant of the dorsal fourth aortic arch. It often presents as part of vascular rings with a right dominant arch. Historically, these have been treated by dividing the ligamentum arteriosum. In recent years, some centers have adopted Kommerell diverticulum resection with subclavian translocation as a primary approach. However, no long-term studies have directly compared outcomes with simple ligamentum division. To address this, we conducted a 21-year dual-institution review comparing short- and long-term outcomes across surgical strategies.
Methods
A retrospective review of 131 patients who underwent vascular ring repair at 2 institutions was performed. Of these, 93 underwent simple ligamentum division and 38 underwent Kommerell diverticulum resection with subclavian artery translocation. Anatomic subtypes, symptoms, perioperative outcomes, and follow-up data were compared.
Results
There were no significant differences in intraoperative or postoperative complication rates between groups. Short-term symptoms such as dyspnea (P = .56), cough (P = .72), and dysphagia (P = .55) were comparable. Rates of recurrent laryngeal nerve injury (P = .67), chylothorax (P = .18), infection (P = .62), hospital stay (P = .49), and 30-day readmission (P = .63) were also similar. Four patients in the simple division group required reoperation; none did in the Kommerell diverticulum group (P = .32). Symptom recurrence at long-term follow-up did not differ significantly (P = .30).
Conclusions
Kommerell diverticulum resection with arterial translocation is safe and effective, with favorable outcomes comparable to simple ligamentum division.

Objective
Esophagectomy remains the mainstay of treatment for patients with end-stage esophageal neuromotor diseases, yet there are limited data on outcomes after esophagectomy in this population. We sought to characterize the safety and efficacy of esophagectomy for esophageal neuromotor disease.
Methods
We retrospectively queried a prospectively collected database of all esophagectomies performed at our institution from 1975 to 2023 for patients without cancer diagnosed with end-stage esophageal neuromotor disease. Operative characteristics, perioperative and functional outcomes, and mortality were evaluated. Patients with and without a previous esophageal operation were compared using χ2 for categorical variables and t test for continuous variables.
Results
We identified 237 patients for analysis. The majority were female (57.0%), White (82.7%), and nonsmokers (83.7%). Mean age was 52.4 years. In total, 185 (78.1%) patients had a diagnosis of achalasia, and 72.2% of patients underwent a previous esophageal operation. The majority of esophagectomies (91.6%) were transhiatal, and a gastric conduit was used in 228 patients (96.2%). Anastomotic leak rate was 9.7% (23/237). One-year mortality was 2.5% (6/237). There were no differences in outcomes between patients who had and had not had a previous esophageal operation. Postoperative functional symptoms were reported in 69.7% of patients at first follow-up, and 97 (40.9%) patients required postoperative dilation for symptom management. The majority of patients reported that they felt better (72%) and would undergo esophagectomy again (72%).
Conclusions
Esophagectomy for esophageal neuromotor disease is safe and feasible with a gastric conduit, regardless of prior esophageal operations. Despite persistent postoperative functional symptoms, patients have high satisfaction after the procedure.

Objective
Failure to rescue, defined as death after a postoperative complication, is a key metric for evaluating hospital performance and surgical quality. We hypothesized that both patient characteristics and hospital performance are associated with failure to rescue risk after esophagectomy.
Methods
We analyzed esophagectomy cases from the Society of Thoracic Surgeons General Thoracic Surgery Database (2012-2023), excluding emergency surgeries and colonic interpositions. The primary outcome was failure to rescue, defined as death within 30 days or during the index hospitalization after a complication. Hospitals were grouped into quintiles based on their risk-adjusted standardized mortality ratio using hierarchical logistic regression. We compared failure to rescue rates between hospitals in the top (very low standardized mortality ratio) and bottom (very high standardized mortality ratio) quintiles using generalized estimating equations to account for clustering. Failure to rescue rates were further stratified across patient risk categories using established Society of Thoracic Surgeons risk metrics.
Results
A total of 28,626 patients from 318 hospitals were included. Top-tier hospitals performed more procedures than bottom-tier hospitals (10,431 vs 3527, P < .001) and had significantly lower unadjusted mortality (1.2% vs 6.6%, P < .001). Adjusted odds of failure to rescue were 4.4 times higher in bottom-tier hospitals (95% CI, 3.6-5.3), with similar trends after major complications (odds ratio, 3.83) and esophagectomy-specific complications (odds ratio, 7.27). Across all patient risk strata, bottom-tier hospitals had higher failure to rescue rates; high-risk patients had an odds ratio of 5.94 (95% CI, 3.6-9.6).
Conclusions
Hospital performance is strongly associated with failure to rescue after esophagectomy, even after adjusting for patient risk. System-level interventions are needed to reduce variation in rescue capacity.

Objective
The use of extracorporeal cardiopulmonary resuscitation (ECPR) in older patients is a controversial practice. The historically high mortality associated with elderly patients who require extracorporeal support frequently dampens the enthusiasm for expending limited, cost-intensive resources on patients of advanced age. We evaluated outcomes in Medicare patients who had suffered sudden acute cardiac arrest and received extracorporeal support.
Methods
We used the United States Medicare Inpatient Analytical Files (2018-2023) to evaluate beneficiaries with cardiac arrest who were placed on venoarterial extracorporeal membrane oxygenation (VA-ECMO). International Classification of Diseases, Tenth Revision codes were used to define comorbidities and frailty using validated metrics.
Results
Of the 5810 Medicare beneficiaries who were placed on VA-ECMO, 1174 experienced cardiac arrest during the same admission and were categorized as the “ECPR cohort.” Their mean Charlson Comorbidity Index score was 2.66 ± 1.36. Approximately one-third had a history of diabetes, liver disease, and chronic renal failure; 52.9% had coronary artery disease, and 65.4% had heart failure. Mortality during hospitalization was 63.8%. Age-stratified 5-year mortality was 69.8% in patients age <70, 78.0% in those age 71% to 80%, and 86.8% in those age >80 years. Conditional on surviving to discharge, mortality was ∼10% at both 1 year and 5 years.
Conclusions
The use of ECPR in Medicare recipients is characterized by high mortality, which further increases with age. This real-world report may help guide the complex clinical decision making in the resuscitation of elderly patients who suffer cardiac arrest.

Objective
We assessed the Model for End-Stage Liver Disease score in patients with mild-moderate scores to predict perioperative outcomes in patients undergoing cardiac surgery.
Methods
The American College Surgeons National Surgical Quality Improvement Program was used to identify patients (2013-2022) undergoing elective isolated coronary artery bypass grafting, aortic valve surgery, or mitral valve surgery. Patients were stratified by low (<9), moderate (9-15), and high (>15) Model for End-Stage Liver Disease scores. Multivariable logistic regression and observed-to-expected ratios were used to assess Model for End-Stage Liver Disease group association and 30-day outcomes.
Results
Of 25,845 patients, 17,743 underwent coronary artery bypass grafting, 5095 underwent aortic valve surgery, and 3007 underwent mitral valve surgery. Increasing Model for End-Stage Liver Disease score (low: n = 18,379; moderate: n = 5922; high: n = 1444) was associated with an increase in mortality for each Model for End-Stage Liver Disease point. The 30-day mortality (low [1.7%], moderate [3.8%], high [8.7%]) and major morbidity (low [25.1%], moderate [33.3%], high [45.7%]) increased with Model for End-Stage Liver Disease severity. Increasing Model for End-Stage Liver Disease category was an independent predictor of 30-day mortality (odds ratio, 1.76; 95% CI, 1.57-1.98) and morbidity (odds ratio, 1.07; 95% CI, 1.02-1.12). The 30-day mortality observed-to-expected ratio was lower in patients with low Model for End-Stage Liver Disease score (observed-to-expected ratio, 0.88; 95% CI, 0.79-0.97) and higher in patients with high Model for End-Stage Liver Disease score (observed-to-expected ratio, 1.15 95% CI, 1.01-1.29). Major morbidity was greater than predicted in all Model for End-Stage Liver Disease categories (all P < .05), driven by increased rates of respiratory complications, renal failure, thromboembolism, and sepsis.
Conclusions
Patients with moderate and low Model for End-Stage Liver Disease scores have adequate outcomes with respect to 30-day mortality. However, surgical risk for patients with high Model for End-Stage Liver Disease scores was underpredicted by traditional risk stratification. Patients with mild to moderate liver disease can undergo cardiac surgery with acceptable surgical mortality.
目的评估轻、中度评分患者的终末期肝病评分模型,以预测心脏手术患者的围手术期预后。方法采用美国外科医师学会国家手术质量改进计划(American College Surgeons National surgery Quality Improvement Program)对2013-2022年接受选择性孤立冠状动脉搭桥术、主动脉瓣手术或二尖瓣手术的患者进行鉴定。患者按终末期肝病模型评分低(<9)、中(>15)和高(>15)进行分层。采用多变量logistic回归和观察-期望比来评估终末期肝病组相关性模型和30天预后。结果25845例患者中,17743例行冠状动脉旁路移植术,5095例行主动脉瓣手术,3007例行二尖瓣手术。终末期肝病模型评分增加(低:n = 18,379;中:n = 5922;高:n = 1444)与终末期肝病模型每个点的死亡率增加相关。30天死亡率(低[1.7%],中[3.8%],高[8.7%])和主要发病率(低[25.1%],中[33.3%],高[45.7%])随着终末期肝病模型严重程度的增加而增加。终末期肝病类别的递增模型是30天死亡率(优势比,1.76;95% CI, 1.57-1.98)和发病率(优势比,1.07;95% CI, 1.02-1.12)的独立预测因子。终末期肝病模型评分低的患者的30天死亡率观察-预期比较低(观察-预期比,0.88;95% CI, 0.79-0.97),终末期肝病模型评分高的患者的30天死亡率较高(观察-预期比,1.15,95% CI, 1.01-1.29)。由于呼吸系统并发症、肾衰竭、血栓栓塞和败血症的发生率增加,所有终末期肝病类别模型的主要发病率均高于预测(P < 0.05)。结论终末期肝病模型评分中低的患者在30天死亡率方面有足够的结果。然而,传统的风险分层低估了终末期肝病模型评分高的患者的手术风险。轻中度肝病患者可接受心脏手术,手术死亡率可接受。

Objective
To assess outcomes after cardiac surgery in patients with epilepsy.
Methods
We queried the 2016-2019 Nationwide Readmissions Database for adult patients undergoing coronary artery bypass grafting, valve and aortic surgeries, or combination procedures. We compared mortality at index admission, complications, and 90-day readmissions between groups of patients with and without epilepsy before and after propensity-score matching. We used logistic regression analysis to evaluate the risk of adverse postoperative outcomes in the epilepsy group compared with their counterparts without epilepsy.
Results
There were 1,104,303 patients identified who underwent cardiac surgery; of those, 15,492 (1.4%) had epilepsy. Patients with epilepsy more often had additional comorbidities, including congestive heart failure, chronic lung disease, and renal failure. Even after propensity-score matching, mortality at index admission (5.2% vs 3.6%), overall complications (44.2% vs 31.4%), and 90-day readmissions (27.3% vs 21.3%) were greater among patients with epilepsy than those without (P < .001 for all comparisons). Patients with epilepsy more frequently experienced specific complications, including stroke, pneumonia and respiratory complications, and infection/sepsis during index admissions. In the adjusted matched analysis, epilepsy was associated with a greater risk of mortality at index admission (adjusted odds ratio [aOR], 1.34; 95% confidence interval, 1.20-1.50), overall complications (aOR, 1.35; 1.28-1.42), and 90-day readmission (aOR, 1.37; 1.29-1.45).
Conclusions
Further studies are necessary to identify strategies to improve outcomes after cardiac surgery in patients with epilepsy, as they have greater associated risks of postoperative mortality, complications, and readmission.
目的评价癫痫患者心脏手术后的预后。方法查询2016-2019年全国再入院数据库中接受冠状动脉搭桥术、瓣膜和主动脉手术或联合手术的成人患者。我们比较了倾向评分匹配前后两组癫痫患者和非癫痫患者在指数入院、并发症和90天再入院时的死亡率。我们使用logistic回归分析来评估癫痫组与非癫痫组术后不良预后的风险。结果共有1,104,303例患者接受了心脏手术;其中,15492人(1.4%)患有癫痫。癫痫患者更常伴有其他合并症,包括充血性心力衰竭、慢性肺病和肾衰竭。即使在倾向评分匹配后,癫痫患者入院时的死亡率(5.2% vs 3.6%)、总并发症(44.2% vs 31.4%)和90天再入院率(27.3% vs 21.3%)均高于无癫痫患者(所有比较的P <; 0.001)。癫痫患者在入院期间更频繁地出现特定并发症,包括中风、肺炎和呼吸道并发症以及感染/败血症。在校正匹配分析中,癫痫与指数入院时更高的死亡率(校正优势比[aOR], 1.34; 95%可信区间,1.20-1.50)、总并发症(aOR, 1.35; 1.28-1.42)和90天再入院(aOR, 1.37; 1.29-1.45)相关。结论:癫痫患者的术后死亡率、并发症和再入院风险较高,需要进一步的研究来确定改善癫痫患者心脏手术后预后的策略。
