Engineered cardiac tissues (ECTs) derived from human induced pluripotent stem cells (hiPSCs) are viable alternatives for repair, patient-specific disease modeling, and drug discovery. However, the immature state of ECTs limits their clinical utility. The microenvironment fabricated using 3D scaffolds can affect cell fate, is crucial maturation ECTs. Herein, authors demonstrate an electric-field-driven (EFD) printed highly ordered microstructure with feature size to promote simulation experimental results that EFD jet microscale printing overcomes repulsion without any prior requirements both conductive insulating substrates. Furthermore, microstructures a fiber diameter 10-20 µm spacing 60-80 have been by maintaining vertical jet, achieving largest ratio diameter/spacing 0.29. hiPSCs-derived cardiomyocytes formed sarcomere growth along developed synchronous functional inside 3D-printed scaffold matured calcium handling compared 2D coverslip. Therefore, process facilitates fabrication providing suitable ECTs, thereby showing great potential tissue engineering.

Abstract Congenital and acquired valvular heart diseases (VHDs) are significant causes of mortality worldwide. With valve replacement being the primary solution for VHD, current options display shortcomings, including calcification, thrombogenicity, hemodynamic alteration, leading to repetitive surgeries. Tissue engineering, however, has shown great potential fabricating valves (HVs) with fewer complications. Here, a series inks developed, combining poly(vinyl alcohol), gelatin, carrageenan 3D printing tissue‐engineered (TEHVs). The inks/hydrogels investigated characterize their physico‐chemical, morphological, mechanical, rheological characteristics. In vitro in vivo biocompatibility, immune response, hemolysis, thrombogenicity also evaluated. Moreover, hydrodynamics TEHVs under physiological conditions reported. Inks demonstrate mechanical characteristics comparable native leaflets. Subcutaneous implantation reveals that hydrogels do not induce chronic inflammation can undergo remodeling. hemocompatibility assessments show minimal hemolysis low thrombogenicity. Different sizes types HVs successfully printed high fidelity air. hydrodynamic assessment confirms withstand aortic conditions. Altogether, 3D‐printed be promising alternative solve problems associated options.

Cardiac tissue lacks regenerative capacity, making heart transplantation the primary treatment for end-stage failure. Engineered cardiac tissues developed through three-dimensional bioprinting (3DBP) offer a promising alternative. However, reproducing native structure, cellular diversity, and functionality of requires advanced bioinks. Major obstacles in CTE (cardiac engineering) include accurately characterizing bioink properties, replicating microenvironment, achieving precise spatial organization. Optimizing properties to closely mimic extracellular matrix (ECM) is essential, as deviations may result pathological effects. This review encompasses rheological electromechanical bioinks function microenvironment design functional constructs. Furthermore, it focuses on improving characteristics, printability, bioinks, offering valuable perspectives developing new especially designed CTE.
