An innovative minimally invasive approach for hypertrophic obstructive cardiomyopathy: Transaortic septal myectomy via right infra-axillary incision.

Objective: To assess the short-term outcomes of the transaortic modified Morrow procedure when performed via a minimally invasive right infra-axillary incision.

Methods: We conducted a retrospective observational study at a single center of patients diagnosed with hypertrophic obstructive cardiomyopathy from September 2021 to July 2023.

Results: The cohort comprised 148 patients (mean age 47.

Minimally Invasive Video-Assisted Surgery for Concomitant Ascending Aorta and Aortic Valve Replacement via Right Infra-Axillary Thoracotomy.

Objective: This study aims to assess the safety, efficacy, and esthetic outcomes of an innovative 4 cm right infra-axillary incision approach for concomitant ascending aorta and aortic valve replacement (AAR and AVR), with a specific focus on achieving optimal surgical outcomes while ensuring minimal visible scarring.

Methods: We retrospectively examined all elective cases of concomitant AAR and AVR surgery performed at our institution from July 2021 to June 2023. Exclusions encompassed emergency surgery, acute type A aortic dissection, active aortic valve endocarditis, redo cardiac surgery, the necessity for concurrent mitral valve replacement, or left ventricular assist device implantation.

ALDH knockout protects against aortic dissection.

Background: The incidence and mortality of aortic dissection (AD) are increasing. In pathological studies, macrophages, T lymphocytes and dendritic cells were found in the tunica media of the aorta. Acetaldehyde dehydrogenase 2 (ALDH) gene polymorphisms are associated with a high incidence of hypertension in Asian populations.

Minimally invasive right infra-axillary thoracotomy for transaortic septal myectomy.

Extended left ventricular septal myectomy remains the gold standard for the treatment of hypertrophic obstructive cardiomyopathy (HOCM) with refractory symptoms. On the basis of traditional modified transaortic Morrow myectomy, we innovatively performed a minimally invasive, video-assisted single-port thoracotomy through the right infra-axillary region. Our procedure can provide good visualization of the left ventricular outflow tract and hypertrophic ventricular septum for accurate resection.

Cardiac Resident Macrophage-Derived Legumain Improves Cardiac Repair by Promoting Clearance and Degradation of Apoptotic Cardiomyocytes After Myocardial Infarction.

Background: Cardiac resident macrophages are self-maintaining and originate from embryonic hematopoiesis. After myocardial infarction, cardiac resident macrophages are responsible for the efficient clearance and degradation of apoptotic cardiomyocytes (efferocytosis). This process is required for inflammation resolution and tissue repair; however, the underlying molecular mechanisms remain unknown.

Elevated c-fos expression is correlated with phenotypic switching of human vascular smooth muscle cells derived from lower limb venous varicosities.

Background: Lower limb venous varicosities (VVs) are clinically common; however, their molecular underpinnings are far from well elucidated. Previous studies have demonstrated that the phenotypic transition of vascular smooth muscle cells (VSMCs) plays a critical role in VV pathogenesis and that c-fos is upregulated in VSMCs from VVs. The present study investigated the histologic and cytologic changes in VVs and the correlation between c-fos upregulation and VSMC phenotypic switching.

The Role of Cariporide in Protecting Saphenous Vein among Different Aldehyde Dehydrogenase Genotypes.

Objective: We aimed to study the effect of cariporide (CP) on protecting the saphenous vein and the role of acetaldehyde dehydrogenase 2 (ALDH2) in coronary artery bypass grafting (CABG).

Background: The saphenous vein is the main graft material used in CABG. Recent studies suggested that CP is effective in protecting against various cardiovascular diseases.

Intravenous transfusion of iron sucrose reduces blood transfusions and improves postoperative anaemia after a second thoracotomy: a propensity-score matching study.

Objective: To evaluate the efficacy of intravenous iron sucrose (IS) in the perioperative period of a second thoracotomy after open-heart surgery.

Methods: This study enrolled patients that underwent a second thoracotomy after previous open-heart surgery. Propensity-score matching was used to match patients that received oral iron therapy with those that received IS after admission.

4,5,6,7-Tetra-chloro-N-(2,3,4-trifluoro-phen-yl)phthalimide.

The asymmetric unit of the title compound, C(14)H(2)Cl(4)F(3)NO(2), contains two independent mol-ecules. In each mol-ecule, the phthalimide ring system is nearly planar [maximum atomic deviation = 0.031 (2) or 0.
