Anatomical and procedural features associated with aortic root rupture during balloon-expandable transcatheter aortic valve replacement [PDF]

, 2013
Aortic root rupture is a major concern with balloon-expandable transcatheter aortic valve replacement (TAVR). We sought to identify predictors of aortic root rupture during balloon-expandable TAVR by using multidetector computed ...

Effectiveness and Safety of Myval Versus Other Transcatheter Valves in Patients Undergoing TAVI: A Meta‐Analysis

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Transcatheter aortic valve implantation (TAVI) has changed the treatment of aortic stenosis. The Myval transcatheter heart valve (THV), a novel balloon‐expandable THV, has shown promising outcomes. Our aim is to compare the comparative safety and effectiveness of Myval THV against established THVs, such as Sapien and Evolut.

Immersed boundary model of aortic heart valve dynamics with physiological driving and loading conditions [PDF]

Int J Numer Meth Biomed Eng, 28(3):317-345, 2012, 2017
The immersed boundary (IB) method is a mathematical and numerical framework for problems of fluid-structure interaction, treating the particular case in which an elastic structure is immersed in a viscous incompressible fluid. The IB approach to such problems is to describe the elasticity of the immersed structure in Lagrangian form, and to describe ...

Arrhythmic risk in elderly patients candidates to transcatheter aortic valve replacement. predicative role of repolarization temporal dispersion [PDF]

, 2019
Degenerative aortic valve stenosis (AS) is associated to ventricular arrhythmias and sudden cardiac death, as well as mental stress in specific patients. In such a context, substrate, autonomic imbalance as well as repolarization dispersion abnormalities ...

A Case Series of Valve‐in‐Valve Transcatheter Aortic Valve Replacement in Stentless Bioprosthetic Valves Using Self‐Expanding Platform With Minimalist Approach

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Valve‐in‐valve (ViV) Transcatheter aortic valve replacement (TAVR) has emerged as a valid treatment option in symptomatic patients with failed aortic bioprosthetic valves, most especially in those with intermediate, high or prohibitive risk of surgery. Due to the unique design of stentless bioprosthetic valves with absence of visible posts and

Massive TAVR

JACC: Case Reports, 2020
A 65-year-old woman with a large adnexal mass was found to have severe bicuspid aortic valve stenosis. Transcatheter aortic valve replacement was chosen rather than surgical aortic valve replacement because of concerns over risks.

Automatic Aortic Valve Pathology Detection from 3-Chamber Cine MRI with Spatio-Temporal Attention Maps [PDF]

arXiv, 2023
The assessment of aortic valve pathology using magnetic resonance imaging (MRI) typically relies on blood velocity estimates acquired using phase contrast (PC) MRI. However, abnormalities in blood flow through the aortic valve often manifest by the dephasing of blood signal in gated balanced steady-state free precession (bSSFP) scans (Cine MRI).

Propensity Matched Analysis of 14 French Suture‐ Versus Plug‐Based Vascular Closure During Transfemoral Transcatheter Aortic Valve Replacement (TAVR)

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Background Plug‐based vascular closure devices (Pb‐VCD) and suture‐based vascular closure devices (Sb‐VCD) are used for percutaneous vascular access site closure during transcatheter aortic valve replacement (TAVR). Until now, no clear superiority of either device was shown in studies comparing 18 F VCDs solely.

A new technological system to revolutionize the management of valvular heart diseases: transcatheter aortic valve for the treatment of aortic stenosis [PDF]

arXiv, 2019
The goal of this study is a technology analysis of a revolution for the management of valvular heart diseases given by new technological system based on transcatheter artificial aortic valve, a delivery catheter and a loading system for the treatment of aortic stenosis (a narrowing of the aortic valve because of calcium build up that restricts blood ...

Using Shockwave Lithotripsy to Treat Severe Calcified Mitral Stenosis in a Pregnant Woman

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Rheumatic mitral stenosis (MS) with significant calcification presents challenges for both surgical and transcatheter interventions. Percutaneous balloon mitral valvuloplasty (PBMV) is often limited in these cases due to valve rigidity, increasing the risk of mitral regurgitation (MR).
