In this paper, we investigated the relationship between intestinal injury, lung injury, and systemic inflammatory responses, with the aim of exploring the mechanism underlying intestinal injury and its impact on systemic inflammatory responses and lung injury in patients with TAAD.

Methods: Patients with TAAD (n=36) and those with aortic root aneurysm (ARA) (n=30) were compared.

Changing of haemostatic system in a pig model during different types of hypothermic circulatory arrest.

Background: Hypothermic circulatory arrest is usually used in aortic surgery, congenital heart defect repairs and other complex surgeries. It is frequently associated with excessive postoperative bleeding and the transfusion of allogeneic blood products. The physiopathology of hypothermic circulatory arrest-induced coagulopathy has never been systematically studied.

Sun's total arch replacement and stent elephant trunk with modified branch-first technique for patients with Stanford type A aortic dissection.

Background: Stanford type A aortic dissection (STAAD) is a critical cardiovascular disease, and surgical procedure is the first-choice treatment. The classical surgical procedure still leads to a high mortality rate and neurological complications. In this study, we introduce a new modified Sun's procedure and investigate the association between the branch-first technique and the postoperative outcomes of patients with STAAD.

Effects of myocardial viability and left ventricular remodeling on survival of patients with heart failure and reduced ejection fraction after coronary artery bypass grafting.

Background: Heart failure with reduced ejection fraction (HFrEF) caused by coronary heart disease (CHD) accounts for the largest proportion of patients with heart failure and is associated with the poorest prognosis. However, date on the perioperative risk and long-term survival of patients with HFrEF are limited. The present study aimed at exploring the effects of the left ventricular end-systolic volume index (LVESVI) and myocardial viability on perioperative risk and long-term survival after coronary artery bypass grafting (CABG) in patients with HFrEF.

Deep Hypothermic Circulatory Arrest Does Not Show Better Protection for Vital Organs Compared with Moderate Hypothermic Circulatory Arrest in Pig Model.

Background: Continued debates exist regarding the optimal temperature during hypothermic circulatory arrest in aortic arch repair for patients with type A aortic dissection. This study seeks to examine whether the use of moderate hypothermic circulatory arrest in a pig model provides comparable vital organ protection outcomes to the use of deep hypothermic circulatory arrest.

Methods: Thirteen pigs were randomly assigned to 30 minutes of hypothermic circulatory arrest without cerebral perfusion at 15°C (n = 5), 25°C (n = 5), and a control group (n = 3).

Ascending aortic dilation in adult patients with congenital ventricular septal defect: An observational study.

Many adult patients with congenital ventricular septal defect (VSD) also developed ascending aortic dilation, but few report the clinical features and surgical management of these patients. This study was designed to study ascending aortic dilation in adult patients with congenital VSD, and summarized the treatment experience and prognosis.To assess the clinical features and surgical management, we performed a retrospective analysis on preoperative data, intraoperative data, and postoperative data from the adult patients with congenital VSD who developed ascending aortic dilation in our institution from February 2010 to December 2016.

CD40L promotes development of acute aortic dissection via induction of inflammation and impairment of endothelial cell function.

Acute aortic dissection is one of the most lethal cardiovascular disease. The major histopathological feature of AAD is medial degradation, especially breakdown of elastin and collagen. However, the underlying mechanism remains a mystery.

The molecular mechanism and signal transduction pathways involved in urothelial cancer (UC) after renal transplantation (RTx) remain unknown. In this study, we investigated the profiling of messenger RNA (mRNA) and long non-coding RNA (lncRNA) in RTx recipients with UC. The mRNA and lncRNA of six pairs of UC and corresponding normal urothelial tissues in RTx recipients were profiled using Arraystar Human lncRNA Microarray V3.

Surgery for mitral regurgitation in patients with aortic root aneurysm: Transaortic or transseptal approach?

Objective: Mitral regurgitation is common in patients with aortic root aneurysm. Mitral valve repair (MVP) or replacement (MVR) can be performed for these patients through either a transverse aortotomy (TA) or transseptal approach (TS). This study sought to compare the early outcomes of mitral valve surgery through the TA and TS approaches and decide which is optimal for this subset of patients.

Disruption of mechanical stress in extracellular matrix is related to Stanford type A aortic dissection through down-regulation of Yes-associated protein.

In this study, we assessed whether the down-regulation of Yes-associated protein (YAP) is involved in the pathogenesis of extracellular matrix (ECM) mechanical stress-induced Stanford type A aortic dissection (STAAD). Human aortic samples were obtained from heart transplantation donors as normal controls and from STAAD patients undergoing surgical replacement of the ascending aorta. Decreased maximum aortic wall velocity, ECM disorders, increased VSMC apoptosis, and YAP down-regulation were identified in STAAD samples.

Downregulation of the Yes-Associated Protein Is Associated with Extracellular Matrix Disorders in Ascending Aortic Aneurysms.

Previous studies indicate that extracellular matrix (ECM) disorders lead to the apoptosis of Vascular Smooth Muscle Cells (VSMCs), which impairs the aortic wall by reducing the generation of elastic fibers, and ultimately result in ascending aortic aneurysm. The critical role of the Yes-associated protein (YAP) has been elucidated in cardiac/SMC proliferation during cardiovascular development. However, the association of YAP expression and extracellular matrix disorders in ascending aortic aneurysms is not clear.
