Management of a trapped Rota-burr 1. Intracoronary NTG injection  2. Balloon dilatation at the site of the stuck burr (Cut off the RA system close to the advancer) Another polymer-coated or stiff wire can be advanced distally to the lesion with the trapped burr. If a conventional angioplasty balloon can not be mobilized due to the poor residual lumen in the GC with the rotablator still in, a second vascular access using another artery for a second GC should be considered. 3. "Mother and Child" Technique with a 5 Fr. GC or a Guideliner (C ut off the RA system close to the advancer ) A Guideliner is more flexible and can be intubated deeply into the coronary artery without traumatizing the vessel.  However, the disadvantage is that the guiding support is not as good as the standard 5 Fr GC. 4. Facilitated burr removal by deep GC intubation ( C ut off the RA system close to the advancer ) Deep intubation with original large size guide catheter and subseq...
