Physiological and clinical consequences of relief of right ventricular outflow tract obstruction late after repair of congenital heart defects. [PDF]

open access: yes, 2006
BACKGROUND: Right ventricular outflow tract obstruction (RVOTO) is a common problem after repair of congenital heart disease. Percutaneous pulmonary valve implantation (PPVI) can treat this condition without consequent pulmonary regurgitation or ...

Granular Hydrogels as Modular Biomaterials: From Structural Design to Biological Responses

open access: yesAdvanced Healthcare Materials, EarlyView.
Granular hydrogels are now emerging as promising biomaterials due to their inherent microporousity, injectability, and modularity. They have shown improvements in cell viability and migration, cellular/tissue infiltration, host tissue integration, mitigated foreign body response, and tissue regeneration.

Left ventricular pacing vector selection by novel echo-particle imaging velocimetry analysis for optimization of quadripolar cardiac resynchronization device: A case report [PDF]

open access: yes, 2016
Background: The availability of pacing configurations offered by quadripolar left ventricular leads could improve patients\u2019 response to cardiac resynchronization therapy; however, the selection of an optimal setting remains a challenge.
