This study aimed to investigate whether driving pressure-guided ventilation can reduce postoperative pulmonary complications in patients who have undergone heart transplantation. Patients who underwent orthotopic heart transplantation were divided into two groups according to the perioperative ventilation strategy: (1) conventional lung-protective ventilation (group C) and (2) driving pressure-guided ventilation (group D). The primary outcome was the occurrence of postoperative pulmonary complications within 30 days of surgery.

This study aimed to establish a predictive model for the risk of post-thoracic endovascular aortic repair (TEVAR) post-implantation syndrome (PIS) in type B aortic dissection (TBAD) patients, assisting clinical physicians in early risk stratification and decision management for high-risk PIS patients. This study retrospectively analyzed the clinical data of 547 consecutive TBAD patients who underwent TEVAR treatment at our hospital. Feature variables were selected through LASSO regression and logistic regression analysis to construct a nomogram predictive model, and the model's performance was evaluated.

Objective: This study aims to develop a predictive model for the risk of major adverse events (MAEs) in type A aortic dissection (AAAD) patients with malnutrition after surgery, utilizing machine learning (ML) algorithms.

Methods: We retrospectively collected clinical data from AAAD patients with malnutrition who underwent surgical treatment at our center. Through least absolute shrinkage and selection operator (LASSO) regression analysis, we screened for preoperative and intraoperative characteristic variables.

Background: This study aimed to assess the early- and mid-term outcomes of aortic root repair and replacement, and to provide evidence to improve root management in acute type A aortic dissection (AAAD).

Methods: This study enrolled 455 patients who underwent AAAD root repair (n = 307) or replacement (n = 148) between January 2016 and December 2017. Inverse probability of treatment weighting (IPTW) method was used to control for treatment selection bias.

The age, creatinine, and ejection fraction (ACEF) score has been accepted as a predictor of poor outcome in elective operations. This study aimed to investigate the predictive value of ACEF score in acute type A aortic dissection (AAAD) patients after total arch replacement. A total of 227 AAAD patients from July 2021 and June 2022 were enrolled and divided into Tertiles 1 (ACEF ≤ 0.

Background: There is a paucity of Chinese studies evaluating the quality of life (QoL) in young acute type A aortic dissection (AAAD) patients with Marfan syndrome.

Methods: Young adult AAAD patients (younger than 45 years old) underwent surgical treatment at our institution from January 2017 to December 2020 were consecutive enrolled. The hospital survivors completed 1 year of follow up.

Article Synopsis
  • The study focuses on predicting postoperative adverse outcomes (PAO) in patients with acute type A aortic dissection (AAAD) after emergency surgery to reduce mortality and improve recovery.
  • Researchers analyzed data from 380 AAAD patients, using LASSO regression to identify clinical factors related to PAO and tested six machine learning algorithms for prediction performance.
  • The extreme gradient boosting (XGBoost) model was found to be the most effective for predicting PAO, utilizing SHAP analysis for individualized risk assessments, thereby enabling timely adjustments in patient care.

Introduction: The aim of this study is to develop a model for predicting the risk of prolonged mechanical ventilation (PMV) following surgical repair of acute type A aortic dissection (AAAD).

Methods: We retrospectively collected clinical data from 381 patients with AAAD who underwent emergency surgery. Clinical features variables for predicting postoperative PMV were selected through univariate analysis, least absolute shrinkage and selection operator regression analysis, and multivariate logistic regression analysis.

Total neointima implantation (patch neointima technique + triple-branched stent graft placement) has been performed in proximal aortic repair for acute type A aortic dissection (ATAAD) for more than 10 years at a center. However, there is no report on the mid-term outcomes with a control group of the surgical procedure. Consequently, the authors aimed to evaluate the safety and efficacy of this technique in this study.

Article Synopsis
  • The study compared the effectiveness of the Castor stent (CS) versus in situ fenestration (ISF) in treating the left subclavian artery in patients with type B aortic dissection over a period from July 2017 to July 2022.
  • Results showed high surgery success rates of 99.3% for CS and 95.5% for ISF, with no deaths reported during hospitalization, but significant differences in surgical duration and complications arose between the two methods.
  • CS had notably fewer stent-related issues, including lower rates of reintervention and complications, indicating it may be a more effective option than ISF for midterm outcomes in TBAD treatment.

Article Synopsis
  • The study aimed to create and validate a nomogram for predicting postoperative transient neurological dysfunctions (TND) in patients with acute type A aortic dissection undergoing a specific type of stent graft surgery.
  • A retrospective analysis of 146 patients identified key predictors for TND, including factors like preoperative creatinine levels and total operation time, and the model demonstrated strong predictive ability with an AUC of 0.818.
  • The long-term survival rates were similar for patients with and without TND, indicating that the nomogram could be a valuable tool for clinicians in assessing TND risk in this patient group.

Objectives: This study aims to determine if complete transthoracic echocardiography (TTE)-guided percutaneous atrial septal defect (ASD) closure without balloon sizing could be safe and efficacious in adult patients.

Methods: A total of 551 patients with ASDs were enrolled in this study, of which 438 patients underwent percutaneous ASD closure. Patients who received TTE-guided percutaneous ASD closure were classified into group T, and those who underwent a procedure that was guided by transesophageal echocardiography (TEE) were classified into group E.

Background: Minimal research has been performed regarding total arch replacement through partial upper sternotomy in patients with acute type A aortic dissection who are obese, and the safety and feasibility of this procedure need to be further investigated. The present study investigated the potential clinical advantages of using a partial upper sternotomy versus a conventional full sternotomy for total arch replacement in patients who were obese.

Methods: This was a retrospective study.

Objective: This study evaluated the antitumor activity and safety of pemigatinib in previously treated Chinese patients with advanced cholangiocarcinoma and fibroblast growth factor receptor 2 (FGFR2) fusions or rearrangements.

Background: Pemigatinib provided clinical benefits for previously treated patients with cholangiocarcinoma carrying FGFR2 fusions or rearrangements and was approved for this indication in multiple countries.

Methods: In this ongoing, multicenter, single-arm, phase II study, adult patients with locally advanced or metastatic cholangiocarcinoma carrying centrally confirmed FGFR2 fusions or rearrangements who had progressed on ≥1 systemic therapy received 13.

Aim: To establish a successful model of heterotopic total small intestinal transplantation (SIT) in rats in order to reduce the complications and increase the survival rate.

Methods: A total of 196 Wistar rats underwent heterotopic SIT with microsurgical technique. Technical modifications included shortening fasting time and supplying energy before surgery, administering optimal volume of crystalloid fluid to the donor and recipient during surgical procedures, reducing mechanical and ischemic injuries to donor intestine, revascularizing small intestinal graft with a combination of conventional aorta to aorta anastomosis and a cuffed portal vein to left renal vein anastomosis which resulted in an acceptably short warm ischemic time, and also an adequate blood supply and drainage of the graft.
