A Complete Occlusion of Right Coronary Artery Due to Stanford Type A Aortic Dissection - Successful Treatment with Extracorporeal Membrane Oxygenation (ECMO).

We present a patient diagnosed Stanford Type A aortic dissection, who was misdiagnosed as acute myocardial infarction for 5 days. In the surgery, the right coronary ostium was totally occluded, and the right coronary artery (RCA) was bluish from the trunk to branches. The true lumen couldn't be found when we opened the RCA.

Integration of Gene Expression Profile Data to Verify Hub Genes of Patients with Stanford A Aortic Dissection.

Thoracic aortic dissection (TAD) is a catastrophic disease worldwide, but the pathogenic genes and pathways are largely unclear. This study aims at integrating two gene expression profile datasets and verifying hub genes and pathways involved in TAD as well as exploring potential molecular mechanisms. We will combine our mRNAs expression profile (6 TAD tissues versus 6 non-TAD tissues) and GSE52093 downloaded from the Gene Expression Omnibus (GEO) database.

Change in Functional Moderate Mitral Regurgitation after Aortic Valve Replacement.

Objective: To evaluate the changes of the mitral valve geometrics and the degrees of moderate mitral regurgitation (MR) in patients undergoing aortic valve replacement (AVR) for aortic stenosis (AS).

Methods: A retrospective analysis study of intraoperative transesophageal echocardiography (TEE) and postoperative transthoracic echocardiography (TTE) was performed in 49 patients diagnosed with pure AS combined with moderate MR, who underwent AVR from January 2013 to December 2017. TEE was used to evaluate the direct geometric changes of the mechanical effects on mitral annulus after AVR.

Experience of the management of coronary artery bypass graft only on moderate ischemic mitral regurgitation: A single-center retrospective study.

To summary the impact of off-pump coronary artery bypass grafting (CABG) only on patients with moderate ischemic mitral regurgitation and survival.We retrospectively analyzed 109 patients with coronary artery disease (CAD) complicated by moderate mitral regurgitation, from January, 2008 to December, 2014, in the Department of Cardiovascular Surgery at the No. 2 Hospital of Jilin University undergoing off pump CABG only.

Early and Medium Outcomes of On-Pump Beating-Heart versus Off-Pump CABG in Patients with Moderate Left Ventricular Dysfunction.

Objective: This study aims to compare the early and medium outcomes of on-pump beating-heart (OPBH) coronary artery bypass grafting (CABG) and off-pump CABG (OPCABG) in patients with left ventricular ejection fraction (LVEF) between 30% and 40%.

Methods: This is a retrospective study of ischemic heart disease patients with LVEF between 30% and 40% who underwent surgical revascularization from January 2013 to December 2017. Patients were divided into OPBH group (n=44) and OPCABG group (n=68), according to the surgical method.

ACT Values after Neutralization Lower than Pre-heparinization ACT Leads to Lower Operative Times, Bleeding, and Post-Operative Transfusions in CABG Patients: an Observational Study.

Objective: To evaluate if lower activated coagulation time (ACT) value after neutralization than preoperative ACT value was effective in reducing bleeding, operative times, and post-operative transfusions in patients underwent coronary artery bypass grafting (CABG).

Methods: Retrospective selection of 398 patients from January 2014 to May 2017. Patients were divided into 2 groups according to final ACT after neutralization: A - final ACT lower than preoperative ACT; and B - final ACT higher than or equal to preoperative ACT.

A New Aortic Arch Inclusion Technique With Frozen Elephant Trunk for Type A Aortic Dissection.

Objective: Our aims were to describe a new surgical technique for the treatment of type A aortic dissection (TAAD) and to report the operative outcomes of 154 patients.

Summary Background Data: Surgical treatment of TAAD is complicated and carries a high mortality risk. To lower this risk, we developed a simplified procedure in which a stent graft was implanted as frozen elephant trunk (FET), and the proximally trimmed vascular graft was sutured from the inside of the aortic arch using the inclusion technique under moderate hypothermic circulatory arrest and antegrade selective cerebral perfusion.

Outcomes Following Coronary Artery Bypass Graft Surgery in Patients with Mild Preoperative Renal Insufficiency.

Introduction: Preoperative renal insufficiency is an independent predictor of mortality after coronary artery bypass graft (CABG) surgery. However, there are few reports aimed to evaluate the impact of mild preoperative renal insufficiency on long-term follow-up outcomes after isolated CABG surgery. This study investigates the effect of mild preoperative renal insufficiency on long-term follow-up outcomes of patients after CABG.

Prx1 promotes the proliferation and migration of vascular smooth muscle cells in a TLR4-dependent manner.

The present study aimed to examine the effect of peroxiredocin 1 (Prx1) on vascular smooth muscle cell (VSMC) proliferation, invasion and migration abilities, and to examine the effect of Toll‑like receptor 4 (TLR4) gene silencing on VSMC proliferation, invasion and migration induced by the overexpression of Prx1. The expression of Prx1 in rats with vein graft intimal hyperplasia (IH) was detected using western blot analysis. In addition, VSMCs were retrovirally transfected to establish stable cell lines overexpressing Prx1.
