Five-Year Clinical and Echocardiographic Outcomes from the Nordic Aortic Valve Intervention (NOTION) Randomized Clinical Trial in Lower Surgical Risk Patients.

open access: yesCirculation, 2019
BACKGROUND The Nordic Aortic Valve Intervention (NOTION) was designed to compare transcatheter aortic valve replacement (TAVR) to surgical aortic valve replacement (SAVR) in patients 70 years or older with isolated severe aortic valve stenosis.

Uncover Hidden Physical Information of Soft Matter by Observing Large Deformation

open access: yesAdvanced Science, EarlyView.
Detecting internal abnormalities in soft matter remains challenging due to its heterogeneous nature. This study introduces a method that infers hidden physical properties by matching observed deformation with simulation through parallel Bayesian optimization.

Surgical Complexity and Outcome of Patients Undergoing Re-do Aortic Valve Surgery

open access: yesOpen Heart, 2020
ObjectivesRe-do aortic valve surgery carries a higher mortality and morbidity compared with first time aortic valve replacement (AVR) and often requires concomitant complex procedures.

Natural history and clinical effect of aortic valve regurgitation after left ventricular assist device implantation [PDF]

open access: yes, 2013
ObjectivesAortic valve regurgitation reduces left ventricular assist device mechanical efficiency. Evidence has also suggested that left ventricular assist device implantation can induce or exacerbate aortic valve regurgitation.

Procedural Volume and Outcomes for Transcatheter Aortic-Valve Replacement.

open access: yesNew England Journal of Medicine, 2019
BACKGROUND During the introduction of transcatheter aortic-valve replacement (TAVR) in the United States, requirements regarding procedural volume were mandated by the Centers for Medicare and Medicaid Services as a condition of reimbursement.

A Design-Based Model of the Aortic Valve for Fluid-Structure Interaction [PDF]

open access: yes, 2020
This paper presents a new method for modeling the mechanics of the aortic valve, and simulates its interaction with blood. As much as possible, the model construction is based on first principles, but such that the model is consistent with experimental observations.

Inhibiting the Histone Demethylase Kdm4a Restrains Cardiac Fibrosis After Myocardial Infarction by Promoting Autophagy in Premature Senescent Fibroblasts

open access: yesAdvanced Science, EarlyView.
Kdm4a downregulation restrains excessive cardiac interstitial fibrosis and remodeling by depressing the premature senescence of fibroblasts in the advanced stage after MI but does not affect early ventricular rupture. It verified that Kdm4a downregulation promotes autophagy in premature senescent fibroblasts by increasing the H3K9m3 modification of the

A Completely Endovascular Solution for Transcatheter Aortic Valve Implantation Embolisation and Inversion into the Aortic ArchWhat this paper adds

open access: yesEJVES Vascular Forum, 2021
Introduction: Transcatheter aortic valve implantation (TAVI) has evolved into the preferred alternative to surgical valve replacement for severe aortic valve stenosis with high surgical risk.

Transcatheter Aortic Valve Replacement on an Aortic Mechanical Valve

open access: yesJACC: Cardiovascular Interventions, 2018
A 71-year-old woman with a history of rheumatic heart valve disease and prior aortic and mitral mechanical valve replacement (Carbomedics #21 and #29, CarboMedics Inc., Austin, Texas, respectively), was referred for transcatheter closure of a mitral perivalvular leak due to New York ...
