We investigated the association between age at the time of EVAR and all-cause mortality in Japan's aging population by stratifying patients into age groups. METHODS: Data from 175 patients who underwent elective EVAR from 2012 to 2016 were analyzed. Patients were categorized into 3 age groups: <75 years, 75-84 years, and ≥85 years, based on Japan's healthy life expectancy and average life expectancy. Survival rates and risk factors for mortality were assessed across these patient groups. RESULTS: Among 175 patients, 3- and 5-year survival rates were significantly lower in elderly patients, with rates of 74.6% and 64.2% for those aged 75-84 years and 51.9% and 39.7% for those aged ≥85 years. Multivariate analysis identified age ≥85 years, chronic kidney disease, chronic obstructive pulmonary disease, and active cancer as independent adverse predictors of all-cause mortality, whereas obesity was identified as an independent protective predictor. CONCLUSIONS: Adjusting guidelines to incorporate not only comorbidities but also age could optimize outcomes and healthcare resource allocation by prioritizing EVAR for patients most likely to benefit in Japan's super-aging society.

In clinical settings, the diagnosis and reperfusion strategies for coronary malperfusion often depend on institutional resources. This study evaluated early surgical outcomes in such patients, focusing on transportation type and clinical management. METHODS: We retrospectively reviewed 70 patients who underwent emergency surgery for AAAD with coronary malperfusion, excluding those with cardiac tamponade on arrival, between 1997 and February 2024. Patients were divided into 2 groups based on transportation: direct transfer and referral. RESULTS: Overall, in-hospital mortality was 27%, with only 1 of 9 patients surviving with preoperative peripheral extracorporeal membrane oxygenation (ECMO). Mortality and morbidity did not significantly differ between groups. Univariate analysis identified left coronary artery involvement and preoperative hemodynamic instability as significant risk factors. Additionally, preoperative diagnostic-only coronary angiography (CAG) with unsuccessful reperfusion was a potential risk factor (P = 0.06). CONCLUSIONS: Regardless of transportation type, preoperative peripheral ECMO itself could not be a definitive solution in AAAD patients with coronary malperfusion. Also, patients who underwent preoperative CAG with unsuccessful reperfusion might be fatal, especially with suspected left coronary artery involvement.

Computed tomography (CT)-measured pulmonary artery (PA) enlargement reflects PA pressure and predicts the prognosis of certain respiratory diseases. We compared the preoperative and postoperative PA diameter to the ascending aorta diameter (PA/A) ratio, investigating its impact on right ventricular function in lung resection. METHODS: This retrospective study was conducted in patients with lower-lobe lung tumors who underwent anatomical lung resection between 2017 and 2022. The PA diameter at the bifurcation and the ascending aorta diameter at the same CT image slice were measured preoperatively and postoperatively. We calculated the enlargement of PA/A ratio (PA/A change) and compared lobectomy and segmentectomy. RESULTS: This analysis included 279 patients (235 with lobectomy and 44 with segmentectomy). The PA/A change was significantly greater in patients with lobectomy than segmentectomy (104% vs. 102%, P = 0.02). In the multivariable analysis, airflow obstruction (yes, P = 0.04) and the type of surgery (segmentectomy, P = 0.04) were independent prognostic factors for PA/A change. CONCLUSIONS: The PA/A change was greater in lobectomy than in segmentectomy. This change could reflect a burden on right ventricular function after lobectomy.

In this study, we aimed to investigate the effectiveness of a method that facilitates securing the operative field using an artificial pneumothorax. METHODS: We analyzed 71 consecutive patients who underwent totally endoscopic off-pump LAA closure and bilateral pulmonary vein isolation. The factors contributing to the reduction in operative time were examined. The patients were divided into the following 2 groups according to whether or not an artificial pneumothorax was used: Group C comprised 24 patients without an artificial pneumothorax and Group A comprised 47 patients with an artificial pneumothorax. RESULTS: There were no hospital deaths or major complications. The operative time was significantly shorter in Group A (108 ± 26 minutes) than in Group C (198 ± 77 minutes) (p <0.0001). CONCLUSIONS: In totally endoscopic off-pump LAA closure and surgical ablation, an artificial pneumothorax may be useful in reducing the operative time.

METHODS: This retrospective cohort study included 110 patients (EGFR mutation group: n = 51; EGFR wild-type group: n = 59) receiving cisplatin-based adjuvant chemotherapy following complete resection of non-small-cell non-squamous-cell lung cancer (2010-2021). Clinicopathological characteristics, recurrence-free survival (RFS), and overall survival (OS) were investigated. RESULTS: The pStage distribution was not statistically different. The EGFR mutation group was characterized by more advanced pN, papillary predominance, and presence of micropapillary components, whereas the EGFR wild-type group exhibited more advanced pT and solid predominant patterns. The median RFS was significantly worse in the EGFR mutation group (23.0 vs. 76.1 months, p = 0.017). Nevertheless, the median OS was not significantly different (85.6 months vs. not reached, p = 0.151). Multivariable analysis demonstrated that EGFR mutation and lymphatic invasion were significant risk factors in RFS; however, no independent factors were identified in OS. CONCLUSIONS: Cisplatin-based adjuvant chemotherapy might be less effective in patients with EGFR-mutated lung cancer. The style of progression and histological pattern related with EGFR mutation may be associated with the efficacy of adjuvant chemotherapy and poor RFS.

Standard procedure requires decalcification followed by reconstruction of the mitral annulus prior to placing the prosthesis. While this is the ideal technique, it is not feasible in every patient due to the associated risks. The mere attempt at valve replacement without proper annular decalcification has been associated with a high incidence of periprosthetic leak which complicates the postoperative course and has been associated with increased morbidity and mortality. With the advances in transcatheter therapy, postoperative periprosthetic regurgitation can be managed with devices and primary transcatheter valve implantation could be alternative to standard valve replacement; however, these alternate strategies are not without its own limitations and drawbacks. In the current report, we present a novel strategy to be used in a select group of patients with severe but non-circumferential annular calcifications to prevent/minimize periprosthetic regurgitation during MVR. This involves placing a patch over the posteriorly located calcium bar, thus minimizing tension on the posterior suture line and contain any periprosthetic regurgitation if to develop. This modification has been performed in a total of nine cases with acceptable early results.

This study aims to compare the metabolic profiles of ONCAB and OPCAB to identify differential metabolites associated with clinical outcomes. METHODS: In a prospective cohort study conducted between January 2023 and September 2023, 100 plasma samples from 20 patients undergoing isolated elective CABG (10 per group) were analyzed. Samples were collected preoperatively and at multiple postoperative time points (Days 0-3) and processed using proton nuclear magnetic resonance (H-NMR). Advanced statistical modeling was applied to identify differential metabolites. RESULTS: No significant differences were found in clinical outcomes, although ONCAB showed higher postoperative CKMB levels. Both procedures induced metabolomic alterations, with ONCAB demonstrating a more substantial impact, particularly on Day 0. Key metabolites, including leucine, succinate, creatine, glucose, and adenine, affected starch and sucrose metabolism. CONCLUSION: ONCAB induces more pronounced metabolic shifts immediately postsurgery, involving protein and energy turnover, oxidative stress, and disrupted glucose metabolism, indicative of cellular stress responses. A comprehensive understanding of these metabolic changes is critical for informing targeted interventions and supports the use of OPCAB as a preferred strategy for patients with elevated metabolic risks.

This case report underscores the complex management of PAS and the necessity of a multidisciplinary approach for accurate diagnosis and treatment. A 52-year-old woman with PAS was diagnosed using imaging and therapeutic tests to distinguish it from pulmonary embolism. Primary treatment included surgical resection of the pulmonary trunk, valve, and tumor, followed by reconstruction. Complete resection was impossible due to extensive endocardial infiltration in the right ventricle, precluding cardiac transplant. The patient underwent adjuvant radiotherapy; however, the disease recurred, and she died 3 years post-diagnosis. This case highlights the rarity of an extensive right ventricle invasion, the absence of clear PAS management guidelines, and the limited evidence on the effectiveness of adjuvant therapies. It concludes that multidisciplinary teams are vital for decision-making and stresses the need for further research to establish effective treatment protocols.

A 46-year-old woman with a history of left breast cancer underwent a left-modified radical mastectomy, adjuvant chemotherapy, and radiotherapy. Despite no known exposure to lipids, she presented with chronic non-productive cough and general malaise. Follow-up chest computed tomography revealed progressive ground-glass opacities in the left lower lung, initially suspected to be lobar bronchioloalveolar carcinoma. Surgical intervention was performed for both diagnostic and therapeutic purposes, confirming the lesion as lipid pneumonia upon pathological examination, revealing the presence of foamy histiocytes.

Among the rarer conditions, UAPA with lung cancer has been previously reported in 13 cases; however, there remains controversy regarding the surgical approach and precautions. Herein, we present a case study of a 56-year-old female patient who was incidentally diagnosed with a nodule in the right lower lobe of the lung during a routine physical examination and subsequently found to have an absent right pulmonary artery upon preoperative evaluation. A wedge resection of the right lower lobe was performed as treatment. Postoperative pathology confirmed invasive adenocarcinoma (pT1N0M0). We provide a narrative review of existing literature on these patients and discuss optimal surgical management strategies.

In this study, we aimed to investigate the impact of CT interval on survival after surgery. METHODS: This retrospective study analyzed the prognosis of 103 patients who underwent periodic CT after complete resection for pathological stage II-III NSCLC at a single institute between 2015 and 2020. The patients were stratified based on the follow-up CT intervals into the half-year group (Group H) and annual group (Group A). Additionally, the underlying differences in clinical backgrounds between the 2 groups were adjusted by propensity score matching. RESULTS: A total of 103 patients (Group H, 76 patients; Group A, 27 patients) were included in this study. The 5-year overall survival (OS) rates in the unmatched cohort were 83.5% and 95.2% in groups H and A, respectively ( P = 0.17). Among the matched cohort, 42 and 21 patients were in groups H and A. The 5-year OS rates of the matched cohort were 89.8% and 94.4% in groups H and A ( P = 0.45), with no significant difference. CONCLUSIONS: There was no association between CT intervals and postoperative survival.

An 82-year-old female underwent proton radiotherapy for left upper lobe lung cancer 10 years previously. Two years after the therapy, a hematoma developed from the left 3rd to 5th dorsal rib fractures and gradually expanded, causing contraction of the left shoulder. Transcatheter arterial embolization was performed; however, the hematoma continued to expand with thrombocytopenia, and the platelet was decreased to 4.2 × 10/μL. Computed tomography showed a 17.2 × 14.0 × 10.0 cm mass between the left scapula and left dorsal ribs. The CEH of the thorax was completely excised with combined resection of the 3rd to 5th ribs, while the brachial plexus was preserved. Postoperatively, the platelet completely recovered and she could raise her left arm. A complete excision with surrounding organs preserved is the strategy used in the treatment of CEH of the thorax.

METHODS: A total of 696 low-risk (Society of Thoracic Surgeons score <4%) AS patients underwent isolated SAVR or TF-TAVR at five centers. After 1:1 propensity score matching, 159 pairs were identified. Early and follow-up events, including cardiac mortality and major adverse cardiac and cerebrovascular events (MACCE: all-cause mortality, heart failure admission, reoperation, prosthetic valve endocarditis, and stroke), were compared. RESULTS: Baseline characteristics are similar between the matched groups. There were no 30-day cardiac mortalities in either group. All-cause mortality and MACCE at 30 days did not differ. During 5-year follow-up (median 3.1 [range 0-7.2] years), the incidence of cardiac mortality (1.3% vs. 18.9%; adjusted hazard ratio [aHR], 8.89; 95% confidence interval [CI], 2.68-29.53; P <0.001), all-cause mortality (4.2% vs. 33.9%; aHR, 8.56; 95% CI, 3.41-21.45; P <0.001), and MACCE (25.1% vs. 47.0%; aHR, 2.36; 95% CI, 1.54-3.63; P <0.001) were lower in the SAVR group than in the TAVR group. CONCLUSIONS: Isolated SAVR demonstrated better outcomes in low-risk AS patients. TAVR in this subset should be chosen carefully.

We introduced the technical details and early and late outcomes by comparing them with those of conventional surgery. METHODS: We retrospectively analyzed patients who underwent lobectomy with hilar and mediastinal lymph node dissection for stages I-III NSCLC. A propensity score-matched analysis was performed based on demographic variables. RESULTS: Propensity score-matching yielded 317 pairs. En bloc surgery was not associated with a longer operation time, a higher amount of intraoperative bleeding, or a higher frequency of postoperative complications. The number of resected lymph nodes (P = 0.277) and frequency of N upstaging (P = 0.587) did not differ between the groups. However, en bloc surgery was associated with higher overall survival in comparison to conventional surgery (P = 0.012). According to a stratification analysis, the survival advantage of en bloc surgery over conventional surgery was remarkable in pathological N-positive disease (P = 0.005), whereas it disappeared in pathological N-negative disease (P = 0.147). CONCLUSION: En bloc surgery is feasible and can be performed in patients with possible N-positive NSCLC.

Data on its performance beyond the short term are limited. We assessed the mid-term outcomes in patients undergoing AVNeo, focusing on feasibility, perioperative details, and its role in AV pathology treatment. METHODS: Sixty-five consecutive patients underwent AVNeo between December 2016 and February 2018. Clinical data were prospectively collected and retrospectively analyzed. Tricuspid reconstruction with autologous pericardium was performed in all cases. Echocardiographic follow-up was conducted post-discharge, at 6 and 12 months, and annually thereafter. RESULTS: The mean age was 62.6 ± 18.7 years. AVNeo was feasible in all cases. Concomitant procedures were performed in 43 (66.2%) patients. Mean bypass and cross-clamp times were 119.2 ± 30.3 and 87.1 ± 22.9 minutes, respectively. Postoperative transvalvular hemodynamics was excellent. There was one (1.5%) in-hospital death. Follow-up (mean 66.72 ± 12.77 months) was complete in 58 patients (89.2%). There were no detected valve-related or thromboembolic events. Transvalvular hemodynamic parameters were stable during the observation period: peak pressure gradient at discharge and follow-up was 15.3 ± 4.6 mmHg and 15.01 ± 6.3 mmHg, respectively (ρ = 0.346). CONCLUSIONS: AVNeo demonstrated the feasibility and favorable mid-term outcomes. Studies with longer-term observation are warranted to evaluate its durability.

In the immediate postoperative period, some patients may still experience life-threatening complications such as reperfusion lung injury, airway bleeding, and persistent pulmonary hypertension with consequent right ventricular dysfunction. These issues may require support with extracorporeal membrane oxygenation (ECMO) as a bridge to recovery or lung transplantation. This study aims to analyze our series of PTEs that require ECMO. METHODS: A descriptive and retrospective analysis of all PTE performed at the Favaloro Foundation University Hospital was conducted between March 2013 and December 2023. RESULTS: A total of 42 patients underwent PTE with a median age of 47 years (interquartile range: 26-76). The incidence of patients with ECMO was 26.6%, of which 53.6% were veno-venous (VV) ECMO. Preoperatively, a low cardiac index (CI), high right and left filling pressures, and high total pulmonary vascular resistances (PVRs) were associated with ECMO with a statistically significant relationship. The hospital mortality was 11.9%, and the mortality in the ECMO group was 45.5%, with a statistically significant relationship. Veno-arterial ECMO has a worse prognosis than VV ECMO. CONCLUSIONS: Preoperatively, a low CI, high right and left filling pressures, and high total PVRs were associated with ECMO after PTE.

METHODS: A detailed search was performed in PubMed, Embase, Web of Science, and the Cochrane Library for cohort studies on lung transplantation. The prognosis of lung transplant recipients was investigated based on the donor age, with the primary outcomes being 1-year overall survival (OS), 3-year OS, 5-year OS, and 5-year chronic lung allograft dysfunction (CLAD)-free survival. RESULTS: This meta-analysis included 10 cohort studies. Among the short-term outcomes, the older donor group demonstrated no significant difference from the young donor group in primary graft dysfunction within 72 hours, use of extracorporeal membrane oxygenation, length of ventilator use, and intensive care unit hours. However, a longer hospital stay was associated with the older donor group. In terms of long-term outcomes, no difference was found between the two groups in 1-year OS, 3-year OS, and 5-year OS. Notably, patients with older donors exhibited a superior 5-year CLAD-free survival. CONCLUSIONS: The results of this meta-analysis indicate that older donors are not inferior to younger donors in terms of long-term and short-term recipient outcomes. Lung transplantation using older donors is a potential therapeutic option after rigorous evaluation.

This study aimed to determine whether esaxerenone exerted cardioprotective effects against cardioplegic arrest in Wistar rat hearts. METHODS: Isolated male Wistar rat hearts aerobically perfused via the Langendorff method for 20 min were randomly allocated to the Control (n = 6; perfused for an additional 10 min and subjected to no treatment) or Esax (n = 6; perfused with 0.1 μmol/L esaxerenone in perfusate for 10 min before ischemia) groups. Hearts in both groups were perfused with St. Thomas' Hospital No. 2 solution (STH2) for 2 min and subjected to 28 min of global ischemia. The recovery of left ventricular developed pressure (LVDP) and total troponin T leakage were measured after reperfusion. RESULTS: The final recovery of LVDP (expressed as a percentage of pre-ischemic value) in the Control and Esax groups was 50.8 ± 3.5% and 62.1 ± 5.6%, respectively (p <0.05, Esax vs. Control). The total troponin T leakage in the Control and Esax groups was 138.8 ± 18.5 ng/g heart wt and 74.3 ± 18.6 ng/g heart wt, respectively (p <0.05, Esax vs. Control). CONCLUSION: The administration of esaxerenone before cardioplegic arrest enhanced the cardioprotective effect exerted by STH2.

METHODS: We conducted a detailed search in PubMed, Embase, Web of Science, and the Cochrane Library, with the primary outcomes being overall survival (OS), acute cellular rejection (ACR), primary graft dysfunction (PGD), and length of stay (LOS). RESULTS: Five cohort studies were included in this meta-analysis, with 183 patients enrolled in the AE-ILD group and 337 patients in the stable-ILD group. The results showed that in regard to perioperative outcomes, the AE-ILD group did not differ from the stable-ILD group in the incidence of ACR (relative risks [RR] = 0.34, p = 0.44) and the incidence of PGD Ⅲ (RR = 0.53, p = 0.43), but had a longer LOS (mean difference = 9.15, p = 0.02). Regarding prognosis, the two also did not differ in 90-day OS (RR = 0.97, p = 0.59), 1-year OS (RR = 1.05, p = 0.66), and 3-year OS (RR = 0.91, p = 0.76). CONCLUSION: Our study concluded that the efficacy of lung transplantation in patients with AE-ILD is not inferior to that of patients with stable ILD. Lung transplantation is one of the potential treatments for patients with AE-ILD.
