Publication Title



This is a Prospective, randomized (like a "flip of a coin") single center study evaluating the ControlRad system device when installed - retrofitted on existing C-arms for fluoroscopy (x-ray) will reduce radiation exposure without compromising image quality in the region of interest and overall workflow during cardiac catheterization and electrophysiology (EP) implant procedures. Enrollment will be limited to 40 cardiac catheterization, and 30 pacemaker and/or ICD procedures. All patients presenting to Beaumont Hospital Royal Oak who are scheduled for cardiac catheterization with coronary angiography and electrophysiology implant in Cath Lab 5 where device is installed will be considered for inclusion in the study. Physicians and staff (20 fellows; 35 attending physicians; and 56 Cath-lab staff,including Nurse/Anesthesia team) will be invited to participate in the study. For each procedure, 3 staff members will be study subjects: a) the primary operator, b) the secondary operator, c) the nurse/tech and or Anesthetist who circulates in the room. Different operators and staff may participate in each case depending on cath-lab scheduling. The Primary operator is the physician who usually stands nearest to the C-arm. In most cases in Beaumont this is a Cardiology Fellow in cardiac catheterization cases and Attending Physician for the EP cases. The Secondary operator is the physician who typically stands to the right of the primary operator and in most cases is the attending cardiologist or scrub assistant (nurse/technician). The Nurse or Anesthesia team typically circulates in the room and is responsible for monitoring the patient, administering medications and obtaining equipment for the procedure.

Two methods will be used to measure radiation dose during the catheterization procedure. The Real-time Dosimeter Badge (RaySafe) and the Landauer Luxel Aluminium Oxide Dosimeter Badges. Cardiac Catheterization and electrophysiology implant procedures will be performed according to standard guidelines.

Participants will be randomized 1:1 to either cardiac catheterization without ControlRad or cardiac catheterization with the ControlRad system. The same 1:1 randomization process will be applied to the EP patient population. Participants will be blinded to the randomization.

Once procedure is done,participation also ended and the badges will be removed by the Radiation Safety Officer or research coordinator.
