Source: Brown, A. O., et al. Visualization of Streptococcus pneumoniae within Cardiac Microlesions and Subsequent Cardiac Remodeling. J. Vis. Exp. (2015).This video demonstrates the microscopic visualization of bacterial microlesions in mouse heart tissue. The heart of a mouse infected with Streptococcus pneumoniae is harvested, washed, and fixed before being processed to obtain coronal sections. These sections are stained with hematoxylin and eosin and examined under a microscope to visualize...

Use of zebrafish for cardiovascular research is expanding towards research on adult hearts. For these applications, quick and simple isolation of cardiac tissues is key to avoid post-mortem changes and to obtain an adequate number of samples. Here, we describe a fast and reproducible method for dissecting adult zebrafish hearts.
FAQs
Image contrast separates blood-filled spaces from cardiac muscle, valves, and surrounding tissues. This distinction allows the atria, ventricles, and connected vessels to be recognized within an image rather than viewed as undifferentiated structures. The resulting boundaries support examination of chamber shape, wall position, valve location, and the relationship between internal spaces and adjacent tissue.
Some imaging approaches emphasize cardiac structure, whereas others capture movement during the heartbeat. Structural views are useful for examining chamber form, wall dimensions, and valve position. Motion-sensitive views add information about wall movement and valve function. Considering both perspectives can provide a more complete assessment than relying on anatomy or movement alone.
The heart changes shape and internal relationships during each heartbeat, so the timing of image capture affects what can be observed. Viewing cardiac motion can reveal how chamber walls move and how valves function, while structural imaging provides a complementary anatomical reference. This temporal context helps distinguish fixed features from changes associated with cardiac activity.
A focused examination can consider the atria, ventricles, connected vessels, chamber dimensions, wall movement, valves, and blood-filled spaces. These features provide complementary information: chamber size describes anatomy, wall movement reflects activity, and valve behavior relates to function. Reviewing them together helps connect the appearance of internal spaces with overall cardiac performance.
Clinicians can use the resulting images to support diagnosis, treatment planning, and monitoring over time. Findings such as chamber size, wall movement, valve function, and blood flow provide different types of clinical information. Repeated visualization can also help identify changes in the heart as a condition progresses or as treatment is followed.
In biology, heart lumen visualization helps researchers examine cardiac development and disease by relating internal anatomy to structure and function. Images can show how chambers, walls, valves, and connected vessels appear or behave in the heart under study. This makes the approach useful for investigating developmental changes and disease-associated alterations in cardiac organization.
