The Heart of a Horse: 3‐D Echocardiographic Analysis of the Equine Aortic Valve [PDF]

open access: yes, 2019
Aortic regurgitation (AR) can be a normal function of aging or a disease in younger horses. Symptoms range from no outward signs to decreased performance to sudden cardiac arrest.

Homocysteine Promotes the Pathogenesis of Atherosclerosis through the Circ‐PIAS1‐5/miR‐219a‐2‐3p/TEAD1 Axis

open access: yesAdvanced Science, EarlyView.
A model is schematically represented for the major molecular mechanisms by which homocysteine (Hcy) accelerates the nuclear export of circ‐PIAS1‐5, which regulates atherosclerosis by acting as a competing endogenous RNA for miR‐219a‐2‐3p. Hcy enrichment of circ‐PIAS1‐5 leads to YTHDC1 binding to circ‐PIAS1‐5 and promotes its intracellular localization ...

Comparative study of wall shear stress at the ascending aorta for different mechanical heart valve prostheses [PDF]

open access: yes, 2019
An experimental study is reported which investigates the wall shear stress (WSS) distribution in a transparent model of the human aorta comparing a bileaflet mechanical heart valve (BMHV) with a trileaflet mechanical heart valve (TMHV) in physiological ...

Association Between Transcatheter Aortic Valve Replacement for Bicuspid vs Tricuspid Aortic Stenosis and Mortality or Stroke.

open access: yesJournal of the American Medical Association (JAMA), 2019
Importance Transcatheter aortic valve replacement (TAVR) indications are expanding, leading to an increasing number of patients with bicuspid aortic stenosis undergoing TAVR.

Dynamic simulation of aortic valve stenosis using a lumped parameter cardiovascular system model with flow regime dependent valve pressure loss characteristics [PDF]

open access: yesarXiv, 2022
Valvular heart diseases are growing concern in impoverished parts of the world, such as Southern-Africa, claiming more than 31 % of total deaths related to cardiovascular diseases. The ability to model the effects of regurgitant and obstructive lesions on the valve body can assist clinicians in preparing personalised treatments.

Fish Swim Bladder‐Derived ECM Hydrogels Effectively Treat Myocardial Ischemic Injury through Immunomodulation and Angiogenesis

open access: yesAdvanced Science, EarlyView.
A unique hydrogel based on extracellular matrix from fish swim bladder, which is suitable for transcatheter delivery and possesses remarkable reparative capabilities for treating heart failure, is developed. It emerges as a multi‐effect factor profoundly influencing inflammation regulation, angiogenesis, and myocardial metabolism.

Survival benefit of overweight patients undergoing MitraClip® procedure in comparison to normal‐weight patients

open access: yesClinical Cardiology, Volume 45, Issue 12, Page 1236-1245, December 2022., 2022
Long‐term survival stratified for weight classes illustrated by Hazard plot for patients treated with MitraClip® implantation stratified for weight classes. Association of weight class compared to normal‐weight with long‐term survival (adjusted for Logistic EuroScore).

Single coronary ostium in a patient with quadricuspid aortic valve combined with aneurysmal ascending aortic dilatation

open access: yesJournal of Cardiothoracic Surgery, 2017
Background The presence of a fourth aortic valve cusp (quadricupsid aortic valve) is a rare congenital malformation and is often accompanied by other anomalies of the adjacent cardiovascular structures.

Bioprosthetic Aortic Valve Fracture During Valve-in-valve Transcatheter Aortic Valve Implantation

open access: yesInterventional Cardiology Review, 2019
The limited durability of surgical bioprostheses, combined with an ageing population, has led to an increasing demand for replacing degenerated bioprosthetic surgical heart valves, which is projected to increase. Valve-in-valve transcatheter aortic valve implantation involves implanting a transcatheter heart valve within a degenerated bioprosthetic ...

Design and Fabrication of Three-Dimensional Scaffolds for Tissue Engineering of Human Heart Valves [PDF]

open access: yes, 2009
We developed a new fabrication technique for 3-dimensional scaffolds for tissue engineering of human heart valve tissue. A human aortic homograft was scanned with an X-ray computer tomograph.
