Influence of the arterial elastic component on the response to balloon angioplasty in femoral arteries of a healthy porcine model

Animal Models and Experimental Medicine, EarlyView.
This study evaluates the role of elastin in vascular response 28 days after balloon angioplasty using uncoated and paclitaxel‐coated balloons in a healthy porcine model. The results show higher elastin content in external femoral arteries, which is inversely correlated with vascular injury, inflammation, smooth muscle cell loss, proteoglycan and fibrin

Unicuspid Aortic Stenosis in a Patient with Turner Syndrome: A Case Report

Frontiers in Cardiovascular Medicine, 2014
Congenital aortic valve anomalies are the cause of premature aortic stenosis in pediatric and younger adult populations. Despite being very rare, unicuspid aortic valves account for approximately 5% of isolated aortic valve replacements.

Echocardiographic evaluation of velocity ratio, velocity time integral ratio, and pulmonary valve area in dogs with pulmonary valve stenosis. [PDF]

, 2018
BackgroundVelocity ratio, velocity time integral (VTI) ratio, and pulmonary valve area indexed to body surface area (iPVA) are methods of assessment of pulmonary valve stenosis (PS) severity that are less dependent on blood flow. Studies evaluating these

Recommendations on the echocardiographic assessment of aortic valve stenosis: a focused update from the European Association of Cardiovascular Imaging and the American Society of Echocardiography.

European Heart Journal-Cardiovascular Imaging, 2017
Echocardiography is the key tool for the diagnosis and evaluation of aortic stenosis. Because clinical decision-making is based on the echocardiographic assessment of its severity, it is essential that standards are adopted to maintain accuracy and ...

Rapid severe hypertension and organ damage in two‐kidney two‐clip rats produced by different sizes of clips

Animal Models and Experimental Medicine, EarlyView.
Blood pressure increases immediately when the 2K2C rats (made with 0.3, 0.25, and 0.2 mm U‐shaped clips) regain consciousness from anesthesia. 100% of the rats develop hypertension on the day of 2K2C surgery. Blood pressure continues to rise, resulting in severe hypertension and organ damage to the brain, heart, aorta, and kidneys at 1, 2, 4, and 6 ...

C-reactive protein in degenerative aortic valve stenosis

Cardiovascular Ultrasound, 2006
Degenerative aortic valve stenosis includes a range of disorder severity from mild leaflet thickening without valve obstruction, "aortic sclerosis", to severe calcified aortic stenosis.

Transcatheter Aortic Valve Replacement in Low-risk Patients With Bicuspid Aortic Valve Stenosis.

JAMA cardiology, 2020
Importance The outcomes of transcatheter aortic valve replacement (TAVR) in low-risk patients with bicuspid aortic valve stenosis have not been studied in a large scale, multicentered, prospective fashion.

SOX6 enhances vascular smooth muscle cell phenotypic switching and elevates blood pressure by activating autophagy

Animal Models and Experimental Medicine, EarlyView.
Sox6 expression is elevated in hypertensive conditions and promotes vascular smooth muscle cell phenotypic switching through autophagy activation. Using gain‐ and loss‐of‐function approaches both in vitro and in vivo, we demonstrate that Sox6 regulates blood pressure and vascular remodeling, highlighting its potential as a novel therapeutic target for ...

Iatrogenic mitral stenosis following transcatheter aortic valve replacement (TAVR)

Indian Heart Journal, 2015
A 57 year old female underwent transcatheter aortic valve replacement (TAVR) for severe aortic stenosis. Mild iatrogenic mitral stenosis was noted intraoperatively. Attempts to reposition the device were hampered by aortic angulation.

Fetal aortic valvuloplasty: first report of two cases from Saudi Arabia

Journal of Cardiothoracic Surgery, 2020
Background Fetal aortic stenosis may progress to hypoplastic left heart syndrome (HLHS), which carries a poor prognosis. We report two infants with fetal aortic stenosis successfully treated with fetal aortic valvuloplasty (FAV) using balloon dilatation.
