• Guideliner
• Snares
• Laser
• Perforation gear
• Rotablator

Clinical Application: Rotablator in Calcification
Calcium is Common
The prevalence of severe calcium, defined as superficial in nature with greater than 180° arc.
Angio assessed 12% of PCI cases
IVUS assessed 26% of cases.1
Calcium can preclude optimal stenting.
Asymmetrical stent expansion occurs in up to 50% of cases where calcium is not treated before stentdeployment.2
DES, rotational atherectomy is an important tool for calcified lesions
Lesion preparation with compliance change for a calcified lesion can substantially facilitate stent delivery andsymmetrical stent expansion for more homogeneous drug delivery.3

Prior to use, please see the complete ‘Directions For Use’ for more information on Indications, Contraindications, Warnings, Precautions, Adverse Events and Operator’s Instructions.
Rotablation : Precautions, ContraindicationsPrecautions
• Ejection fraction less than 30%
• Lesions longer than 25mm
• Angulated lesions
• Recommend temporary pacemaker in the RCA and dominant Cx
• Rotablator System use should only be carried out at hospitals where
emergency bypass surgery can be immediately performed in the event
of a potentially injurious or life threatening complication.
Contraindications• Saphenous Vein Grafts
• Last Remaining Vessel
• Thrombus
• Significant Dissection
• Non-surgical candidates

Conclusions
• Many CTO cases are done today in highly calcified lesions.
• Succesful passage with guide wire in CTO in not the success of procedure.
• Rotablation is very useful in calcified CTO lesions cases.
• Rotablation in CTO cases will definitely increased in numbers in the nearest future.
