Background: Reduced risk of bleeding, reduced hospital stay, and increased comfort has increased the use of the transradial approach for percutaneous coronary procedures. However, risk of increased operator exposure to scatter radiation is a concern, for the transradial approach. The Cardiovascular TransRadialAccess Platform(Cardio-TRAP®) is a radiation protection technology with ergonomic modular design consisting of a Base Board, lead-encasing Shield, Right Radial Base, Left Radial Base, and a Left Arm Board (for left vascular access). The Shield has a 1mm-thick lead core sealed in HDPE polymer, designed to absorb more than 95% of incident radiation. It offers scatter radiation protection for the cardiologist and scrub nurse in their most neglected zones (arms, face, and head). All other Cardio-TRAP® components are fully radio-lucent, allowing a clear and normal fluoroscopy image.
Objective: To compare radiation exposure received by Cath Operators to hands, neck, and head between additionally shielded (with Cardio-TRAP®) and unshielded groups.
Method: Observational, randomized, prospective, single center comparative study was conducted at an Indian Hospital, highly experienced with radial access. The protocol was approved by an independent ethics committee. Four calibrated electronic dosimeters (IPD-1301) were attached to right wrist, left wrist, right collar and forehead of cardiologist and technician respectively. Operators were randomly divided into shielded and unshielded groups and radiation doses at the four body sites were recorded during right transradial PCI
Results: A total of 18 subjects (mean age 56.14 ± 1.32 years) were enrolled, 9 subjects in each arm. Procedural table height averaged 90 ± 2.4 cms, with average procedural time of 29.75± 3.5min. In the shielded group, Air Kerma(mGy) and DAP(mGy) doses were lower for the cardiologist and technician, respectively (1051±838.6 and 58953.8±44055), versus the unshielded group (1779.1±189.5 and 108009.5±23550.9), p<0.01.
Conclusions: The Cardio-TRAP®) is a simple but novel technology offering significant protection against operator radiation exposure (41-45% reduction) during right radial-access PCI.
