Rotathon-series of successful rota cases last 2 months: An audit

Abstract

Background

Physical removal of plaque and reduction in plaque rigidity facilitating dilation.

1. Rotablader ablates plaque using a; 

 • Diamond encrusted elliptical burr
• Rotated at high speed ( 140,000 to 180,000 rpm)
• By a helical driveshaft
• That advances gradually across a lesion over a guidewire.

2. Burr preferentially ablates

• Hard, inelastic material, such as calcified plaque,
• That is less able to stretch away from the advancing burr than healthy arterial wall
• This is referred to as “differential cutting”
