Chrysin alleviates pressure overload–induced myocardial remodeling through regulating the PI3K/AKT/NRF2 pathway–mediated oxidative stress response

Animal Models and Experimental Medicine, EarlyView.
In this study, we primarily simulated pathological myocardial remodeling induced by transverse aortic constriction surgery and found significant cardiac hypertrophy and fibrosis, characterized by deteriorated cardiac function. Oxidative stress response is considered as a pivotal pathological process, which contributes to inflammation and apoptosis of ...

Two Reports of Quadricuspid Aortic Valve With Aortic Insufficiency

Reviews in Cardiovascular Medicine, 2017
We report two cases of a quadricuspid aortic valve with severe aortic incompetence. Both patients presented with dyspnea on exertion. Their physical examinations demonstrated wide pulse pressures with diastolic murmurs. Bedside transthoracic Doppler echocardiography revealed preserved left ventricular systolic function and possible quadricuspid aortic ...

Morphological and morphometric aspects of the equine aortic valve: New insights for comparative studies in mammals

The Anatomical Record, EarlyView.
Abstract New data on the equine aortic valve obtained using advanced techniques is especially important given the greater availability of animal models for translational research. Here we characterized the morphological and morphometric aspects of the equine aortic valve from 60 healthy hearts collected at equine abattoirs.

Evaluation of aortic valve insufficiency after supracoronaryreplacement with resuspension for acute type A aorticdissection

, 2012
Aim: Aortic dissections emerge as severe pathologies reqiuring early diagnosis and immediatesurgical intervention is mandatory in acute Type A aortic dissection, however,there are still controversies regarding the appropriate approach.

Emergency Valve-in-Valve Transcatheter Aortic Valve Implantation for the Treatment of Acute Stentless Bioprosthetic Aortic Insufficiency and Cardiogenic Shock

Case Reports in Cardiology, 2018
Bioprosthetic aortic valve degeneration may present as acute, severe aortic regurgitation and cardiogenic shock. Such patients may be unsuitable for emergency valve replacement surgery due to excessive risk of operative mortality but could be treatable ...

Trans-apical aortic valve implantation for quadricuspid aortic valve with aortic regurgitation using J-valve system: a case reports

Journal of Cardiothoracic Surgery, 2021
Background Quadricuspid aortic valve (QAV) is a rare congenital heart defect usually accompanied with different hemodynamic abnormalities. Due to the rarity of QAV, treatment and prognosis of QAV patients with aortic regurgitation still remain ...

Quadriscupid Aortic Valve with Concurrent Aortic Stenosis and Insufficiency

Journal of the Belgian Society of Radiology, 2016
We present the case of a 22-year-old man with a congenital mixed aortic valve dysfunction who underwent cardiac Magnetic Resonance Imaging (MRI) for the assessment of aortic valve morphology and function prior to valve replacement. Cardiac MRI showed a four-leaf-clover aortic valve morphology, the typical presentation of a quadricuspid aortic valve ...

Clinical Anatomy of the Left and Right Atrial Appendages in Humans: Comparative and Developmental Perspective

Clinical Anatomy, EarlyView.
ABSTRACT Human atrial chambers derive from distinct embryonic anlagens, the original embryonic atria gradually transforming into the so‐called auricles, or atrial appendages. This study quantifies macroscopic variations in pectinate muscle architecture in human atrial appendages and evaluates their visualization using clinical imaging modalities.
