What is transthoracic echocardiography?
It is a noninvasive imaging technique used to assess cardiac function in mice.
Why is body temperature important during the procedure?
Maintaining body temperature is crucial as fluctuations can affect cardiac function.
What imaging modes are used in this technique?
B mode, M mode, and Doppler imaging are utilized to assess different aspects of cardiac performance.
How is anesthesia managed during the procedure?
Anesthesia is carefully monitored and adjusted to maintain a target heart rate throughout the imaging.
What parameters are measured in echocardiography?
Systolic and diastolic functions, as well as blood flow patterns across the mitral valve, are measured.
