A methodology to estimate ventricular fiber orientations from in vivo images of patient heart geometries for personalized modeling is described. Validation of the methodology performed using normal and failing canine hearts demonstrate that that there are no significant differences between estimated and acquired fiber orientations at a clinically observable level.

Right ventricle (RV) dysfunction is critical to the pathogenesis of cardiovascular disease, yet limited methodologies are available for its evaluation. Recent advances in ultrasound imaging provide a noninvasive and accurate option for longitudinal RV study. Herein, we detail a step-by-step echocardiographic method using a murine model of RV pressure overload.

Kv channel dysfunction is associated with cardiac arrhythmias. In order to study the molecular mechanisms that lead to such arrhythmias we utilize a systematic protocol for isolation of atrial and ventricular cardiomyocytes from Kv channel ancillary subunit knockout mice. Isolated cardiomyocytes can then immediately be used for cellular electrophysiological studies, biochemical or immunofluorescence (IF) assays.

Primary cell culture is a useful technique for analyzing specific populations of cells, particularly from transgenic mouse embryos at specific developmental stages. Herein, embryonic ventricles are dissected and dissociated, and antibody-conjugated beads recognize and separate out the endothelial cells for further analysis.
FAQs
Ventricular septum separation depends on a sequence of tissue contributions rather than on muscular growth alone. The muscular interventricular septum extends upward, while endocardial cushion tissue participates in closing the remaining opening. Formation of the membranous septum completes this closure. Cell differentiation and tissue remodeling coordinate these events, making both tissue identity and structural reorganization important to the outcome.
Endocardial cushion tissue is important because it contributes to closure of the interventricular opening after the muscular septum has grown upward. The later membranous septum provides an additional structural component in completing separation. Considering these tissues together helps explain why models of cardiac development must represent multiple coordinated processes, rather than treating chamber formation as a single growth event.
Proper septal formation establishes the anatomical separation needed for distinct ventricular chambers and efficient directional blood flow. Consequently, abnormalities in the growth, closure, differentiation, or remodeling events can be examined in relation to congenital ventricular septal defects. This connection gives the process significance beyond anatomy by linking developmental biology with the study of structural heart disease.
In cardiac organoids, ventricular septum separation can serve as a developmental feature to reproduce when building models of chamber formation. These systems can help investigate how ventricular structures emerge and examine the underlying developmental mechanisms. Their value lies in creating an experimental context that connects tissue organization with questions about congenital defects and cardiac development.
Engineered heart tissues can apply knowledge of septal development to construct models that better reflect the formation of ventricular compartments. Such models are relevant when researchers need to evaluate developmental mechanisms in a bioengineered setting. They may also support work directed toward cardiac repair and regenerative medicine, where understanding how separation develops informs the design of restorative strategies.
Microphysiological models provide a bioengineering context for representing ventricular development. By reproducing tissue events associated with muscular septum growth, endocardial cushion participation, membranous closure, differentiation, and remodeling, these systems can be used to study chamber formation. They also offer a framework for examining congenital ventricular septal defects and evaluating approaches relevant to cardiac repair.
