Balloon Rupture during Pre-Dilation for Transcatheter Aortic Valve Replacement in Patients with a Bicuspid Aortic Valve: Classification, Treatment Strategies, and Prevention

Cardiovascular Innovations and Applications, 2023
Balloon rupture during transcatheter aortic valve replacement (TAVR) is a rare but serious complication. Here, we present two cases of balloon rupture in patients with severe aortic stenosis and type 0 bicuspid aortic valves.

Engineering Strain‐Stiffening Granular Hydrogels for 3D‐Printed Tissue‐Mimicry

Advanced Materials, EarlyView.
A 3D‐printable strain‐stiffening double‐network granular hydrogel (SDGH) enables independent, region‐specific tuning of toe (EToe) and heel (EHeel) moduli through control of microgel packing and network composition. This platform replicates tissue‐like nonlinear mechanics and allows fabrication of high‐fidelity, multilayered aortic valves with ...

Super‐Resolution Ultrasound Based Cell Tracking With Polymeric Nanobubbles

Advanced Materials, EarlyView.
This study presents a super‐resolution ultrasound platform for tracking cells in vivo. Biocompatible polymeric nanobubbles are used as highly echogenic intracellular labels. Following the injection of cells and microbubbles, ultrasound localization microscopy (ULM) can dynamically match the microvascular architecture and individual cell trajectories ...

Novel biaxial tensile test for studying aortic failure phenomena at a microscopic level

BioMedical Engineering OnLine, 2013
Background An aortic aneurysm is a local dilation of the aorta, which tends to expand and often results in a fatal rupture. Although larger aneurysms have a greater risk of rupture, some small aneurysms also rupture. Since the mechanism of aortic rupture

ADAMTS4-specific MR probe to assess aortic aneurysms in vivo using synthetic peptide libraries

Nature Communications, 2022
New biomarkers are required to improve the assessment of aortic wall integrity and risk of rupture. Here the authors report the development of an imaging probe for ADAMTS4, which they test in an abdominal aortic aneurysm mouse model and show in vivo ...

Additive Manufacturing of Patient‐Specific Intracranial Aneurysm Cell Culture Models

Advanced Materials Technologies, EarlyView.
Patient‐specific intracranial aneurysm models were fabricated using chocolate moulding, 3D printed water‐soluble cores, and direct resin 3D printing. Moulding PDMS around sacrificial cores made of chocolate or 3D printed water‐soluble resin yielded accurate, expandable, and endothelializable models that outperformed resin‐based approaches.
