Special Issue Information

Dear Colleagues,

Advanced experimental and computational biomechanics have become essential components for a better understanding of the physiological and pathological conditions of biological tissues in the human body. Recent advances in medical imaging modalities, image segmentation, tissue characterization experiments, and predictive computer simulations have made major contributions to transforming current therapeutic paradigms towards the facilitations of patient-specific diagnostics and individualized surgery planning.

This Special Issue on “Advances in Biological Tissue Biomechanics”, therefore, will focus on original research papers and comprehensive reviews, dealing with cutting-edge experimental and computational methodologies for multiscale biomechanical investigations of biological tissues in the human body system. Topics of interest for this Special Issue include, but are not limited to, the following:

  1. Advanced experimental techniques for characterizing biological tissue mechanics
  2. Novel microstructure-based constitutive model for biological tissues
  3. Growth, remodeling and repair in biological tissues
  4. Quantification of in vivo functional biomechanical properties of biological tissues
  5. Investigations of interrelationship of tissue’s biomechanical behavior to its underlying microstructure
  6. Verification, validation and uncertainty quantification in image-based patient-specific simulations
  7. Advanced computational biomechanics, such as reduced-order modeling, for fast personalized surgery simulations and pre-operative treatment planning
  8. Molecular and cellular biomechanics informed tissue biomechanics

All research areas considered relevant as long as experimentations and/or predictive simulations are the main study drivers.

Artificial heart valves may dysfunction, leading to thrombus and/or pannus formations. Computational fluid dynamics is a promising tool for improved understanding of heart valve hemodynamics that quantify detailed flow velocities and turbulent stresses to complement Doppler measurements. This combined information can assist in choosing optimal prosthesis for individual patients, aiding in the development of improved valve designs, and illuminating subtle changes to help guide more timely early intervention of valve dysfunction. In this computational study, flow characteristics around a bileaflet mechanical heart valve were investigated. The study focused on the hemodynamic effects of leaflet immobility, specifically, where one leaflet does not fully open. Results showed that leaflet immobility increased the principal turbulent stresses (up to 400%), and increased forces and moments on both leaflets (up to 600% and 4000%, respectively). These unfavorable conditions elevate the risk of blood cell damage and platelet activation, which are known to cascade to more severe leaflet dysfunction. Leaflet immobility appeared to cause maximal velocity within the lateral orifices. This points to the possible importance of measuring maximal velocity at the lateral orifices by Doppler ultrasound (in addition to the central orifice, which is current practice) to determine accurate pressure gradients as markers of valve dysfunction.
