Advancing aortic stenosis assessment: validation of fluid-structure interaction models against 4D flow MRI data [PDF]

arXiv
Systematic in vivo validations of computational models of the aortic valve remain scarce, despite successful validation against in vitro data. Utilizing a combination of computed tomography and 4D flow magnetic resonance imaging data, we developed patient-specific fluid-structure interaction models of the aortic valve immersed in the aorta for five ...

Right ventricular dysfunction predicts outcome after transcatheter mitral valve repair for primary mitral valve regurgitation

European Journal of Heart Failure, Volume 24, Issue 11, Page 2162-2171, November 2022., 2022
RVD predicts outcome after M‐TEER for PMR. CI, confidence interval; HR, hazard ratio; PMR, primary mitral regurgitation; RVD, right ventricular dysfunction. Abstract Aims Right ventricular dysfunction (RVD), as expressed by right ventricular to pulmonary artery coupling, has recently been identified as a strong outcome predictor in patients undergoing ...

The anatomopathology of bicuspid aortic valve [PDF]

, 2011
The bicuspid aortic valve is a common congenital heart disease characterised by inequality of cusp size, a central raphe, and smooth cusp margins even in diseased valves.

Closure of a Late‐Onset Iatrogenic Left Ventricular Pseudoaneurysm Caused by Erosion of an Apical Muscular VSD Device

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT We report the case of a 3‐year‐old asymptomatic girl (12 kg, 96 cm) who was diagnosed with a large iatrogenic left ventricular pseudoaneurysm (LVP) on follow‐up ultrasound, 14 months after apical muscular ventricular septal defect (VSD) closure with a 10 mm Amplatzer Muscular VSD occluder (Abbott, USA) due to device erosion.

Steerable Delivery Sheath for Optimized LAA Closure: First Experience and Procedural Outcomes

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Background The new Amplatzer Steerable Delivery Sheath is a delivery system designed to improve ease‐of‐use and procedural results of left atrial appendage closure (LAAC). We aimed to compare procedural results after switching our LAAC program at a tertiary care center with the Amulet device to the Steerable Delivery Sheath, with a control ...

Aortic Root Anatomy and Impact on New‐Onset Left Bundle Branch Block After Transcatheter Aortic Valve Implantation

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Background Angulation of virtual basal ring (VBR), also known as aortic annulus, in relation to sino‐tubular junction (STJ) may lead to greater exposure of implanted stent to the conduction system, consequently increasing the risk of left bundle branch block (LBBB).
