Abstract:
Transaortic septal myectomy is a procedure that involves a learning curve for surgeons because the bulging interventricular septum usually interferes with the visualization of the deep parts of the left ventricular chamber. In this case report, we demonstrate computed tomography virtual endoscopy for preoperative simulation, which enabled us to clearly image the relationship among the bulging septum, the expected myectomy area, and the structures deep in the left ventricle, such as the papillary muscle and abnormal muscular bundles, which are hidden by the hypertrophic septum, thus preventing visualization. This approach could make minimally invasive transaortic septal myectomy safe and easy.

Virtual Work
In static equilibrium, a body can experience an imaginary or virtual movement, such as displacement or rotation. The virtual work done by a force is equal to the dot product of force and virtual displacement in the direction of the force. When it comes to virtually rotating a...
