The radioprotective effect of the cathpax air cabin during interventional cardiology procedures

Abstract

\n \n \n Type of funding sources: Public hospital(s). Main funding source(s): Hospital Puerta del Mar\n \n \n \n \xa0The use of ionizing radiation during cardiac catheterization interventions adversely impacts both the patients and the medical staff.\xa0\xa0Traditional radiation protection equipment is only partially effective. The Cathpax® radiation protection cabin (RPC) has demonstrated to significantly reduce radiation exposure in electrophysiological and neuroradiology interventions. Our objective was to analyze whether the Cathpax® RPC reduces radiation dose in coronary and cardiac structural interventions in unselected real-world procedures.\xa0\n \n \n \n \xa0In this non-randomized all-comers prospective study, 119 consecutive cardiac interventional procedures were alternatively divided into two groups: the RPC group (n\u2009=\u200959) and the non-RPC group (n\u2009=\u200960).\xa0No significant changes in patients and procedures characteristics, average contrast volume, air kerma (AK), dose area-product (PDA) and fluoroscopy time between both groups were apparent.\n In RPC group, the first operator relative radiation exposure was reduced by 78% at the chest and by 70% at the wrist. This effect was consistent during different types of procedures including complex percutaneous interventions and structural procedures.\n \n \n \n \xa0Our study demonstrates, for the first time, that the Cathpax® cabin significantly and efficiently reduces relative operator radiation exposure during different types of interventional procedures, confirming its feasibility in a real-world setting.
