Efficacy and Safety of Emergent Transcatheter Aortic Valve Implantation in Patients with Acute Decompensated Aortic Stenosis: Systematic Review and Meta-Analysis

open access: yesJournal of Interventional Cardiology, 2021
Introduction. The aim of this systematic review and meta-analysis was to investigate the efficacy and safety of emergent transcatheter aortic valve implantation (TAVI) in patients with decompensated aortic stenosis (AS) by comparing the clinical outcomes

Prosthetic Heart Valve [PDF]

open access: yesCirculation, 2011
A 55-year-old invasive/clinical cardiologist worked full time, exercised regularly, and was asymptomatic. Two weeks previously, he had new onset of angina on exertion. Echocardiography/Doppler and cardiac catheterization confirmed the clinical assessment of severe aortic stenosis with a valve area of 0.5 cm2/m2.

One-Year Outcomes of Mitral Valve-in-Valve Using the SAPIEN 3 Transcatheter Heart Valve.

open access: yesJAMA cardiology, 2020
Importance Bioprosthetic mitral valves are implanted with increasing frequency but inevitably degenerate, leading to heart failure. Reoperation is associated with high morbidity and mortality.

The Heart Valves

open access: yesCardiology Plus, 2021
Abstract The four heart valves are arranged in different planes from each other. The aortic valve is most centrally located being related to all four cardiac chambers.

Heart valve isogeometric sequentially-coupled FSI analysis with the space–time topology change method

open access: yesComputational Mechanics, 2020
Heart valve fluid–structure interaction (FSI) analysis is one of the computationally challenging cases in cardiovascular fluid mechanics. The challenges include unsteady flow through a complex geometry, solid surfaces with large motion, and contact ...

Valve-in-valve Transcatheter Aortic Valve Replacement for Failed Surgical Valves and Adjunctive Therapies

open access: yesUS Cardiology Review, 2022
While redo surgical aortic valve replacement has traditionally been the gold standard for the treatment of failed surgical valves, valve-in-valve (ViV) transcatheter aortic valve replacement (TAVR) has arisen as a viable, less invasive option with the ...

Mechanisms of heart valve development and disease

open access: yesDevelopment, 2020
The valves of the heart are crucial for ensuring that blood flows in one direction from the heart, through the lungs and back to the rest of the body. Heart valve development is regulated by complex interactions between different cardiac cell types and ...

Concomitant aortic regurgitation predicts better left ventricular reverse remodeling after transcatheter aortic valve replacement

open access: yesBMC Cardiovascular Disorders, 2023
Background We aim to determine predictors of inadequate left ventricular mass index (LVMi) regression at mid-term after transcatheter aortic valve replacement (TAVR), including the potential role of epicardial adipose tissue (EAT).

Biology and Biomechanics of the Heart Valve Extracellular Matrix

open access: yesJournal of Cardiovascular Development and Disease, 2020
Heart valves are dynamic structures that, in the average human, open and close over 100,000 times per day, and 3 × 109 times per lifetime to maintain unidirectional blood flow.
