ABSTRACT Background Transcatheter aortic valve implantation (TAVI) in bicuspid aortic valve (BAV) anatomy remains challenging due to anatomical complexity and limited trial data. New‐generation balloon‐expandable valves, such as Myval, require further evaluation in this subgroup.

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

Abstract Aims The extent of irreversible cardiomyocyte necrosis after acute myocardial infarction (AMI) is a major determinant of residual left ventricular (LV) function and clinical outcome. Cell therapy based on CD34+ cells has emerged as an option to help repair the myocardium and to improve outcomes.

Abstract Soft robots, engineered from highly compliant materials, offer superior adaptability and safety in unstructured environments compared to their rigid counterparts. Recent advancements, fueled by bio‐inspiration and material programmability, have led to the rapid co‐evolution of their core modules: actuation, sensing, protection, energy, and ...

Non infective severe aortic paravalvular leakage 7 years after surgery: the role of suture technique
We report a case of redo aortic prosthesis replacement for a severe paravalvular leak (PVL) in a man operated with continuous suture technique 7 years earlier. The severe aortic regurgitation was due to the rupture of the suture.

Assessment of prosthetic aortic valve performance by magnetic resonance velocity imaging [PDF]
Objectives: Magnetic resonance (MRI) velocity mapping was used to evaluate non-invasively the flow profiles of the ascending aorta in normal volunteers and in patients with an aortic (mechanical) valve prosthesis.

Fluid dynamic characterization of a polymeric heart valve prototype (Poli-Valve) tested under continuous and pulsatile flow conditions. [PDF]
PURPOSE: Only mechanical and biological heart valve prostheses are currently commercially available. The former show longer durability but require anticoagulant therapy; the latter display better fluid dynamic behavior but do not have adequate durability.

Mono‐ and bivalent‐, alanine‐modified poly‐iso‐butylenes, folding into beta‐sheets, were prepared by living carbocationic polymerization and subsequent endgroup modification. These PIB‐conjugates are useful as solid polymers for the drug release of triamcinolone and nimodipine. ABSTRACT Poly‐iso‐butylene (PIB) is a well known biocompatible polymer with
