Can have Coolsculpting/Cryolipolysis on my neck when both my Aortic & Pulmonary valves have had mechanical replacements?

I take Warfarin and also have a pacemaker. However from what I've read this shouldn't prevent me from having Coolsculpting/Cryolipolysis provided the area treated is not near to where the pacemaker is. Can you confirm if this is the case and if my mechanical valve replacements would prevent me from getting thw treatment?
