Fetal and perinatal death is a common feature when studying genetic alterations affecting cardiac development. High-frequency ultrasound imaging has improved 2-D resolution and can provide excellent information on early cardiac development and is an ideal method to detect the impact on cardiac structure and function prior to death.

Transthoracic echocardiography offers a noninvasive method for the evaluation of cardiac function in mice. A combination of ultrasound and Doppler imaging modalities can be used to obtain dimensional measurements of the heart and intracardiac blood flow, which together provide an assessment of cardiac systolic and diastolic performance.

This video demonstrates use of a rail-mounted high-frequency ultrasound probe to perform echocardiography on an anesthetized mouse. The methods describe both conventional two-dimensional and M-mode measurements of cardiac function in addition to newer, more powerful tools such as color Doppler, strain analysis, as well as general and targeted contrast imaging.

As leveling involves measuring vertical distances relative to a horizontal line of sight, it requires a graduated rod, called a level rod, for vertical measurements and an instrument called a level for a horizontal sight line. A level includes a high-powered telescope with a mechanism for leveling to ensure the line of sight is horizontal when the bubble in the spirit level is centered. Leveling rods, made of wood, metal, or fiberglass, are graduated in feet or meters and commonly used in two-...

FAQs
Each mode answers a different cardiac question. Two-dimensional imaging displays cardiac structures, M-mode focuses on their motion over time, and Doppler evaluates blood-flow direction and velocity. Used together, these functions connect anatomy, movement, and flow, helping clinicians interpret chamber size, valve motion, wall movement, and overall cardiac function rather than relying on one image type.
Doppler adds blood-flow information that structural imaging alone does not provide. By analyzing returning ultrasound signals, it indicates the direction in which blood moves and measures its velocity. This information complements findings about valves, chambers, and walls, making flow a distinct part of the examination rather than relying only on the appearance or motion of cardiac structures.
Because echocardiography equipment assesses the heart without ionizing radiation, it provides a non-ionizing option for cardiac evaluation. This feature distinguishes the approach from modalities that use ionizing radiation and supports its role in diagnosis and monitoring. Clinicians can examine cardiac structures, motion, and flow while retaining that radiation-free characteristic.
Portable echocardiography equipment extends cardiac assessment beyond a fixed imaging setting. Its use in emergency, critical-care, and bedside environments allows clinicians to bring ultrasound-based evaluation closer to patients who require immediate or localized assessment. The clinical value lies in access and placement, expanding where cardiac structures, motion, and blood flow can be examined.
Interpretation focuses on several complementary findings: chamber size, valve motion, wall movement, and cardiac function. Doppler findings add blood-flow direction and velocity to the structural and motion assessment. Reviewing these features together helps clinicians identify abnormalities and follow changes over time, supporting both diagnostic evaluation and monitoring of cardiac conditions.
Echocardiography equipment is useful when clinicians evaluate valvular disease, heart failure, congenital abnormalities, or fluid around the heart. These applications span structural, functional, and disease-monitoring needs: valve motion and cardiac function can be assessed, while imaging helps examine abnormalities involving chambers, walls, or surrounding fluid.
