Registered Cardiovascular Invasive Specialist (RCIS) Practice Test

When using the Rotoblador device, when should the burr begin to rotate?

1. At the lesion site

2. Just proximal to the lesion

3. Just distal to the lesion

4. Immediately upon insertion

The correct answer is: Just proximal to the lesion

The correct choice indicates that the burr should begin to rotate just proximal to the lesion. This practice ensures that the burr is effectively engaged and can create a smooth transition in the lesions being treated, minimizing trauma to the surrounding tissue. Starting to rotate the burr before reaching the lesion allows for better control, preventing potential complications or damage as the device approaches sensitive areas. This technique provides an appropriate cutting action as the burr advances toward the lesion, ensuring that the altered tissue is managed effectively. Performing this action just proximal helps in preparing the site, as the rotation establishes the effectiveness of the burr's cutting mechanism before making contact with the lesion itself.
