The natural sequential collapse method (NSCM) can be employed during surgery to reduce the duration of segmentectomy. This method avoids inflating the lung by rapidly blocking vessels within the tumor basin. It is important to note that the color of the lungs should be used to determine the surgical procedure. The NSCM is efficient and straightforward in revealing the intersegmental plane.

Background: Infective endocarditis (IE) remains a challenging disease associated with high mortality. Several scores have been suggested to assess surgical risk. None was sufficiently adequate. We therefore analyzed risk factors for 30-day mortality.
Methods: A total of 438 consecutive patients had surgery for IE in our department between 2002 and 2020. Patients were divided into two groups, one consisting of 30-day survivors (362 patients; 82.6%) and one of nonsurvivors (76 patients; 17.4%). Logistic regression analysis on pre- and intraoperative risk factors was performed and the groups were compared by univariable analyses.
Results: Patients in mortality group were older (69 [58, 77] vs. 63 [50, 72] years; p < 0.001), EuroSCORE II was higher (24.5 [12.1, 49.0] vs. 8.95 [3.7, 21.2]; p < 0.001) and there were more females. More frequently left ventricular function (below 30%), preoperative acute renal insufficiency, chronic dialysis, insulin-dependent diabetes mellitus, NYHA-class IV (New York Heart Association heart failure class IV), and cardiogenic shock occurred. Patients in the mortality group were often intensive care unit patients (40.8 vs. 22.4%; p < 0.001) or had a preoperative stroke (26.3 vs. 16.0%; p = 0.033). In the nonsurvivor group Staphylococcus aureus was prevalent. Streptococcus viridans was common in the survivor group as was isolated aortic valve endocarditis (32.9 vs. 17.1%; p = 0.006). Prosthetic valve endocarditis (PVE) and abscesses occurred more often in nonsurvivors. In the logistic regression analysis, female gender, chronic dialysis, cardiogenic shock, and NYHA IV and from intraoperative variables PVE, cardiopulmonary bypass time, and mitral valve surgery were the strongest predictors for 30-day mortality.
Conclusion: This study indeed clearly indicates that significant risk factors for 30-day mortality cannot be changed. Nevertheless, they should be taken into account for preoperative counselling, and they will alert the surgical team for an even more careful management.
背景:感染性心内膜炎(IE)仍然是一种具有挑战性的疾病,死亡率很高。已经提出了几种评估手术风险的评分方法。但没有一项足够充分。因此,我们分析了30天死亡率的风险因素:方法:2002 年至 2020 年间,共有 438 名连续患者在我科接受了 IE 手术。患者分为两组,一组为 30 天存活患者(362 例;82.6%),另一组为非存活患者(76 例;17.4%)。对术前和术后风险因素进行了逻辑回归分析,并通过单变量分析对两组进行了比较:结果:死亡组患者年龄较大(69 [58, 77] 岁 vs. 63 [50, 72] 岁;p p p = 0.033)。在非死亡组中,金黄色葡萄球菌最常见。病毒性链球菌和孤立性主动脉瓣心内膜炎(32.9% 对 17.1%;P = 0.006)在幸存者组很常见。人工瓣膜心内膜炎(PVE)和脓肿在非幸存者中发生率更高。在逻辑回归分析中,女性性别、慢性透析、心源性休克和 NYHA IV 以及术中变量 PVE、心肺旁路时间和二尖瓣手术是 30 天死亡率的最强预测因素:这项研究确实清楚地表明,30 天死亡率的重要风险因素是无法改变的。尽管如此,在术前咨询时应考虑到这些因素,并提醒手术团队采取更谨慎的管理措施。

Introduction: Chest wall and/or diaphragm reconstruction aims to preserve, restore, or improve respiratory function; conserve anatomical cavities; and upkeep postural and upper extremity support. This can be achieved by utilizing a wide range of different grafts made of synthetic, biological, autologous, or bioartificial materials. We aim to review our experience with decellularized bovine pericardium as graft in the past decade.
Patients and methods: We conducted a retrospective analysis of patients who underwent surgical chest wall and/or diaphragm repair with decellularized bovine pericardium between January 1, 2012 and January 13, 2022 at our institution. All records were screened for patient characteristics, intra-/postoperative complications, chest tube and analgesic therapy duration, length of hospital stay, presence or absence of redo procedures, as well as morbidity and 30-day mortality. We then looked for correlations between implanted graft size and postoperative complications and gathered further follow-up information at least 2 months after surgery.
Results: A total of 71 patients either underwent isolated chest wall (n = 51), diaphragm (n = 12), or pericardial (n = 4) resection and reconstruction or a combination thereof. No mortality was recorded within the first 30 days. Major morbidity occurred in 12 patients, comprising secondary respiratory failure requiring bronchoscopy and invasive ventilation in 8 patients and secondary infections and delayed wound healing requiring patch removal in 4 patients. There was no correlation between the extensiveness of the procedure and extubation timing (chi-squared test, p = 0.44) or onset of respiratory failure (p = 0.27).
Conclusion: A previously demonstrated general viability of biological materials for various reconstructive procedures appears to be supported by our long-term results.

Objective: This study aimed to determine the impact of symptom-to-surgery time on mortality in acute type A aortic dissection (ATAAD) patients, with and without malperfusion.
Methods: A retrospective analysis of 288 ATAAD patients was conducted. Patients were separated into the early (≤10 h) and late (>10 h) groups by symptom-to-surgery time. Data on characteristics, surgery, and complications were compared, and multivariable logistic regression determined mortality risk factors.
Results: Mortality rates did not significantly differ between early and late groups. Age (odds ratio [OR] 1.09, 95% CI 1.05-1.13, p < 0.001), extracorporeal membrane oxygenation use (OR 10.73, 95% CI 2.51-45.87, p = 0.001), and malperfusion (OR 6.83, 95% CI 2.84-16.45, p < 0.001) predicted operative death. Subgroup analysis showed cerebral (OR 3.20, 95% CI 1.11-9.26, p = 0.031), cardiac (OR 5.89, 95% CI 1.32-26.31, p = 0.020), and limb (OR 6.20, 95% CI 1.75-22.05, p = 0.005) malperfusion as predictors of operative death. One (OR 6.30, 95% CI 2.39-16.61, p < 0.001), two (OR 12.79, 95% CI 2.74-59.81, p = 0.001), and three (OR 46.99, 95% CI 7.61-288.94, p < 0.001) organs malperfusion, together with Penn B (OR 7.96, 95% CI 3.04-20.81, p < 0.001) and Penn B-C (OR 12.50, 95% CI 2.65-58.87, p = 0.001) classifications predict operative mortality. Survival analysis revealed significant differences between malperfusion and no malperfusion (34% vs. 9%, p < 0.001) but not between late and early (14% vs. 21%, p = 0.132) groups. Malperfusion remained an essential predictor of operative (OR 7.06 95% CI 3.11-17.19, p < 0.001) and midterm mortality (OR 3.38 95% CI 1.97-5.77, p < 0.001) in subgroup analysis.
Conclusion: Preoperative malperfusion status, rather than symptom-to-surgery time, significantly impacts both operative and midterm mortality in ATAAD patients.

Background: Rapid and accurate diagnosis of infective endocarditis (IE) allows timely management of this life-threatening disease and improves outcome. The Duke criteria have traditionally been the clinical method for diagnosing IE. These criteria were reformulated at different timepoints. We aimed to evaluate the real accuracy of the modified Duke criteria based on several studies that concluded the diagnosis of IE.
Methods: Three databases were assessed. Studies were considered for inclusion if they reported the use of modified Duke criteria as the initial approach and the confirmation of the diagnosis with the gold standard methods. The meta-analysis of diagnostic test accuracy was performed after fitting the hierarchical summary receiver operating characteristic model (HSROC) with bivariate model and displaying the summarized measures of sensitivity and specificity, and positive and negative likelihood ratios.
Results: A total of 11 studies were included. Accuracy in the included studies ranged from 62.3 to 92.2%, sensitivity ranged from 58.3 to 84.0%, and specificity ranged from 50.0 to 100%. The combined overall sensitivity and specificity were 85% (95% CI: 0.77-0.90) and 98% (95% CI: 0.89-0.99), respectively. The positive likelihood ratio was 40.2 (95% CI: 7.26-220.74) and the negative likelihood ratio was 0.15 (95% CI: 0.01-0.23).
Conclusion: The analysis reveals that the modified Duke criteria have a high positive likelihood ratio, suggesting a robust correlation between a positive test result and the existence of IE, and a very good overall specificity at 98%. The latter aspect holds significant importance in order to prevent unnecessary overtreatment, given the intricacies involved in managing IE.

Introduction: Cardioplegia, a therapy designed to induce reversible cardiac arrest, revolutionized cardiovascular surgery. Among the various pharmacological approaches is the histidine-tryptophan-ketoglutarate (HTK) solution. Despite numerous studies, no meta-analysis has investigated the efficacy of the HTK solution in the pediatric population. Therefore, we aim to conduct a meta-analysis comparing HTK and other cardioplegia solutions in pediatric patients undergoing cardiovascular surgery.
Methods: PubMed, Embase, and Cochrane databases were searched from inception through April 2024. Endpoints were computed in odds ratios (OR) with 95% confidence intervals (CI) for dichotomous variables, whereas continuous variables were compared using mean differences (MD) with 95% CI.
Results: A total of 11 studies comprising 1,349 patients were included, of whom 677 (50.19%) received HTK cardioplegia. The results were similar between groups regarding mortality (OR 0.98; 95% CI 0.29, 3.29), length of hospital stay (MD 0.32 days; 95% CI -0.88, 1.51), Mechanical ventilation (MV) (MD -17.72 hours; 95% CI -51.29, 15.85), arrhythmias (OR 1.27; 95% CI 0.83, 1.95), and delayed sternal closure (OR 0.89; 95% 0.56, 1.43). However, transfusion volume was lower in the HTK group (MD -452.39; 95% CI -890.24, -14.53; p = 0.04).
Conclusion: The use of HTK solution was demonstrated to be similar regarding its clinical efficacy to other approaches for cardioplegia, and it may present advantages to patients prone to hypervolemia.
简介心脏麻痹是一种旨在诱导可逆性心脏停搏的疗法,它彻底改变了心血管外科手术。组氨酸-色氨酸-酮戊二酸(HTK)溶液是各种药理学方法中的一种。尽管有许多研究,但还没有一项荟萃分析调查了 HTK 溶液在儿科人群中的疗效。因此,我们旨在对接受心血管手术的儿科患者进行一项荟萃分析,比较 HTK 和其他心脏麻痹溶液:方法:检索了从开始到 2024 年 4 月的 PubMed、Embase 和 Cochrane 数据库。对于二分变量,终点以几率比(OR)和95%置信区间(CI)计算,而连续变量则以平均差(MD)和95%置信区间进行比较:结果:共纳入了 11 项研究,1,349 名患者,其中 677 人(50.19%)接受了 HTK 心脏麻痹。在死亡率(OR 0.98;95% CI 0.29,3.29)、住院时间(MD 0.32 天;95% CI -0.88,1.51)、MV(MD -17.72小时;95% IC -51.29,15.85)、心律失常(OR 1.27;95% CI 0.83,1.95;)和胸骨闭合延迟(OR 0.89;95% 0.56,1.43)方面,各组结果相似。然而,HTK 组的输血量较低(MD -452.39;95% CI -890.24,-14.53;P=0.04):结论:HTK溶液的临床疗效与其他心脏麻痹方法相似,对易发生高血容量的患者有一定优势。

Background: Lung cancer is the most prevalent and lethal cancer globally, necessitating accurate differentiation between benign and malignant pulmonary nodules to guide treatment decisions. This study aims to develop a predictive model that integrates artificial intelligence (AI) analysis with biomarkers to enhance early detection and stratification of lung nodule malignancy.
Methods: The study retrospectively analyzed the patients with pathologically confirmed pulmonary nodules. AI technology was employed to assess CT features, such as nodule size, solidity, and malignancy probability. Additionally, lung cancer blood biomarkers were measured. Statistical analysis involved univariate analysis to identify significant differences among factors, followed by multivariate logistic regression to establish independent risk factors. The model performance was validated using receiver operating characteristic curves and decision curve analysis (DCA) for internal validation. Furthermore, an external dataset comprising 51 cases of lung nodules was utilized for independent validation to assess robustness and generalizability.
Results: A total of 176 patients were included, divided into benign/preinvasive (n = 76) and invasive cancer groups (n = 100). Multivariate analysis identified eight independent predictors of malignancy: lobulation sign, bronchial inflation sign, AI-predicted malignancy probability, nodule nature, diameter, solidity proportion, vascular endothelial growth factor, and lung cancer autoantibodies. The combined predictive model demonstrated high accuracy (area under the curve [AUC] = 0.946). DCA showed that the combined model significantly outperformed the traditional model, and also proved superior to models using AI-predicted malignancy probability or the seven lung cancer autoantibodies plus traditional model. External validation confirmed its robustness (AUC = 0.856), achieving a sensitivity of 0.80 and specificity of 0.86, effectively distinguishing between invasive and noninvasive nodules.
Conclusion: This combined approach of AI-based CT features analysis with lung cancer biomarkers provides a more accurate and clinically useful tool for guiding treatment decisions in pulmonary nodule patients. Further studies with larger cohorts are warranted to validate these findings across diverse patient populations.

Introduction: Lactate dehydrogenase (LDH) is a standard postoperative marker for hemolysis in the presence of paravalvular leakage (PVL) after replacement of the aortic valve (AVR). LDH is elevated in certain valves by a fluttering phenomenon. Previous studies suggested a correlation between microparticles (MPs) and LDH elevation after AVR. Thus, we analyze the postoperative relevance of LDH after AVR with transapical transcatheter aortic valves (TA-TAVs) or rapid deployment valves (RDVs).
Methods: We retrospectively analyzed the data from patients who received an AVR with the RDV and TA-TAV groups between 2015 and 2018. We compared PVL and LDH levels before and after surgery, transvalvular gradients, heart block that required pacemaker implantation, and 30-day mortality.
Results: In total, 138 consecutive patients were selected for the study: 79 patients in the RDV group (37 Sorin Perceval valve, 42 Edwards Intuity valve) and 59 in the TA-TAV group (Edwards Sapien valve). TA-TAV group was older (median 10 years) and had a higher incidence of PVL (odds ratio 11, 95% confidence interval [CI] 2.5-73.2, p = 0.04)). Interestingly, the TA-TAV group showed lower levels of LDH despite higher rates of PVL. Of note, the Perceval valve trended toward higher LDH values. Additionally, the RDV group showed an increased arrhythmia profile (p = 0.0041); however, the results show lower incidence in pacemaker implantation (95% CI 0.05-1.65, p = 0.635). The 30-day mortality was similar between groups.
Conclusion: Our data do not support the association between hemolysis and PVL despite elevated LDH in suture-free valves. Our results suggest that LDH could be a marker of extreme heart muscle output or fluttering phenomenon and not a marker of hemolysis after sutureless AVR.

Objective: The goal of this study is to examine early and midterm results after surgical treatment of acute DeBakey type I aortic dissection (AIAD) and the effect of the range of aortic arch replacement on overall survival and prevention of distal aortic events.
Methods: Between March 2002 and July 2020, a total of 374 AIAD aortic repairs were reviewed. A total of 154 (41.2%) patients had total arch replacement (TAR), whereas 220 (58.8%) had hemi- or partial arch replacement (PAR).
Results: Operative mortality did not show a significant difference (7.7% in PAR, 13.0% in TAR, p = 0.096). Survival at 5 years showed no difference (77.8% in TAR, 72.6% in PAR, p = 0.14). Freedom from reoperations and reinterventions, as well as composite aortic events in the distal aorta, were comparable across groups (p = 0.21, 0.84, and 0.91, respectively). The inverse probability of treatment weighting-adjusted model displayed higher 5-year freedom from reoperations and aortic events in the TAR group (p = 0.029 and 0.054, respectively).
Conclusion: The extent of arch replacement is determined based on the patient background, making it difficult to compare the superiority of both surgical methods. However, TAR for appropriately selected patients may provide the benefit of avoiding aortic events in the long term.

Background: Coronary artery bypass grafting (CABG) is one of the revascularization modalities available in patients with left ventricular dysfunction (LVD). Multiple arterial grafting (MAG) is associated with improved long-term outcomes. Data on the benefits of MAG in patients with LVD are limited. We examined the effect of MAG on outcomes across the spectrum of left ventricle (LV) function.
Methods: Retrospective cohort study of patients undergoing isolated CABG (January 1, 2009, to October 1, 2021). Patients were grouped according to revascularization strategy (single vs. MAG). The primary outcome was a composite of all-cause mortality, cerebrovascular accident, myocardial infarction, and repeat revascularization (major adverse cardiac and cerebrovascular events [MACCE]). The cumulative incidence of MACCE was plotted using Kaplan-Meier curves. Results were stratified according to LV function (<30%, 30-50%, >50%).
Results: Our cohort included 4,763 patients; 1,976 (41.4%) underwent single arterial grafting (SAG), and 2,787 (58.6%) underwent MAG; 3,976 (83.4%) were male with a median age of 64 (interquartile range [IQR] 57-71) years. Distribution of LV function was 2,539 (53.3%) with an ejection fraction (EF) >50%, 1,828 (38.3%) with an EF of 30-50%, and 396 (8.3%) with an EF <30%. Median follow-up time was 64 (37-102) months. Cumulative incidence of MACCE at 72 months was 28.7% in the MAG and 30.3% in the SAG group. Stratified by LV function, the hazard ratio for MACCE at 160 months was 0.71 (95% CI 0.54-0.93), 0.78 (95% CI 0.68-0.9), and 0.95 (95% CI 0.83-1.09) for LV function <30%, 30-50%, >50%, respectively, with no significant interaction between MAG and LV function.
Conclusion: MAG is associated with improved outcomes following CABG across the spectrum of LV function.
