Accompanying notes on the pathology models highlight the echocardiographic features displayed. The superb interactive functionality of the HeartWorks software is retained.
Variants of the Left Arial Appendage Anatomy:
Unilobed, Multilobed and Hooked
There is considerable variability in the morphology of the left atrial appendage (LAA). It is important to understand the normal anatomical arrangements in order to accurately evaluate the appendage when considering the possibility of thrombus or for interventions specifically related to the appendage such as insertion of closure devices.
The LAA is characteristically described as a finger-like projection from the left atrium, near the left pulmonary veins, but it may be hooked or have one or more additional lobes. With as many as 80% of people who will have more than one lobe to the LAA, this pathology module has been designed for students of echocardiography to familiarize themselves with LAA anatomical features and corresponding ultrasound views.
Doppler enhancements to Global Left Ventricular Dysfunction
Flow velocity data has been added to the existing ventricular dysfunction models (Pathology Module 1). Spectral and colour flow Doppler displays demonstrate characteristic appearances of abnormal diastolic ventricular function with functional mitral regurgitation. Appearances of the left ventricular global dysfunction model have been enhanced.
