We present the protocols to examine mouse heart development using whole mount epifluorescent microscopy on mouse embryos dissected from ventricular specific MLC-2v-tdTomato reporter knock-in mice. This method allows us to directly visualize each stage of the ventricular formation during mouse heart development without labor-intensive histochemical methods.

Goergen, Weldon School of Biomedical Engineering, Purdue University, West Lafayette, Indiana In this video, high field, small-bore magnetic resonance imaging (MRI) with physiological monitoring is demonstrated to acquire gated cine loops of the murine cardiovascular system. This procedure provides a basis for assessing left-ventricular function, visualizing vascular networks, and quantifying motion of organs due to respiration. Comparable small animal...

Streptococcus pneumoniae forms discrete non-purulent microscopic lesions in the heart. Outlined is the protocol for a murine model of cardiac microlesion formation. Instruction is provided on microlesion visualization using microscopy, discrimination between early and late microlesions, and methods to detect cardiac remodeling in hearts of convalescent animals.

FAQs
Valve motion is governed by pressure changes within the heart. As pressures shift, the valves open or close, limiting blood movement to one direction through the chambers. This mechanism is clinically important because it maintains one-way flow through pulmonary and systemic circulation, making valve behavior part of chamber-based assessment.
These measurements describe different aspects of chamber performance. Size and wall thickness provide structural information, whereas contractility reflects pumping action and filling reflects how a chamber receives blood. Considering them together helps clinicians recognize patterns associated with heart failure, congenital defects, or cardiomyopathy rather than relying on a single finding.
A chamber finding becomes more informative when structural and functional measurements are considered together. Chamber size and wall thickness describe structure, while contractility and filling describe functional behavior. This combined view supports clinical evaluation of possible heart failure, congenital defects, or cardiomyopathy and provides a broader basis for interpreting cardiac performance.
Echocardiography, cardiac MRI, and other imaging methods can provide both structural and functional measurements of the heart's chambers. Structural information supports evaluation of chamber size and wall thickness, while functional information addresses contractility and filling. Using these outputs helps clinicians assess cardiac findings, plan treatment, or follow changes over time.
A chamber-focused assessment can organize measurements around four domains: size, wall thickness, contractility, and filling. Clinicians obtain these data with echocardiography, cardiac MRI, or other imaging methods, then use the structural and functional results to support diagnosis, treatment planning, or monitoring during ongoing clinical follow-up care.
Clinicians may evaluate cardiac chambers when assessing heart failure, congenital defects, or cardiomyopathy. The resulting measurements can show chamber structure and function in a way that supports diagnosis, helps guide treatment planning, and allows changes to be monitored over time. This makes chamber assessment useful for both initial evaluation and clinical follow-up.
