Abstract
<p style="text-align:justify"><span style="font-family:Arial,Helvetica,sans-serif"><span style="font-size:16px"><span style="color:#000000"><strong>Introduction:</strong></span></span></span></p> <p style="text-align:justify"><span style="font-family:Arial,Helvetica,sans-serif"><span style="font-size:16px"><span style="color:#000000">Radiation exposure increases alongside technological advances and the complexity of cardiovascular interventions, raising concerns for healthcare professionals in Interventional Cardiology. </span></span></span></p> <p style="text-align:justify"><span style="font-family:Arial,Helvetica,sans-serif"><span style="font-size:16px"><span style="color:#000000">The <em>Cathpax®</em> radiation protection cabin (RPC) was developed to minimize work-related exposure, offering superior protection and potentially eliminating the need for heavy lead aprons, thereby reducing orthopedic injuries. However, its large size significantly alters cath lab dynamics, requiring an adaptation period for the entire team and impacting patient preparation and cleaning processes.</span></span></span></p> <p style="text-align:justify"> </p> <p style="text-align:justify"><span style="font-family:Arial,Helvetica,sans-serif"><span style="font-size:16px"><span style="color:#000000"><strong>Objective:</strong></span></span></span></p> <p style="text-align:justify"><span style="font-family:Arial,Helvetica,sans-serif"><span style="font-size:16px"><span style="color:#000000">We aim to assess the implications of using the <em>CATHPAX® AIR</em> radiation protection cabin in the Cath Lab's workflow.</span></span></span></p> <p style="text-align:justify"> </p> <p style="text-align:justify"><span style="font-family:Arial,Helvetica,sans-serif"><span style="font-size:16px"><span style="color:#000000"><strong>Methods:</strong></span></span></span></p> <p style="text-align:justify"><span style="font-family:Arial,Helvetica,sans-serif"><span style="font-size:16px"><span style="color:#000000">A single-center retrospective study was conducted from January to November 2024, analyzing diagnostic and interventional cardiology procedures. We compared procedures before and after the cabin's implementation, excluding the first month due to team adaptation and incomplete cabin use. After this period, prepping and cleaning procedures were optimized, and the <em>CATHPAX </em>was used in nearly all cases. </span></span></span></p> <p style="text-align:justify"><span style="font-family:Arial,Helvetica,sans-serif"><span style="font-size:16px"><span style="color:#000000">Study endpoints included fluoroscopy time, patient exposure dosage, and contrast usage, along with intraprocedural complications and procedure success. </span></span></span></p> <p style="text-align:justify"><span style="font-family:Arial,Helvetica,sans-serif"><span style="font-size:16px"><span style="color:#000000">Statistical analyses were performed using Independent-Samples T-Test, Chi-square, and Mann-Whitney U tests with SPSS software.</span></span></span></p> <p style="text-align:justify"> </p> <p style="text-align:justify"><span style="font-family:Arial,Helvetica,sans-serif"><span style="font-size:16px"><span style="color:#000000"><strong>Results:</strong></span></span></span></p> <p style="text-align:justify"><span style="font-family:Arial,Helvetica,sans-serif"><span style="font-size:16px"><span style="color:#000000">A total of 528 procedures were analyzed, 311 (199 diagnostic angiograms and 122 interventions) before and 217 (149 angiograms and 68 interventions) after the cabin implementation. </span></span></span></p> <p style="text-align:justify"><span style="font-family:Arial,Helvetica,sans-serif"><span style="font-size:16px"><span style="color:#000000">Patients had a mean age of 67.8 ± 10.2 years, 72.4% were male, 37.1% presented with Acute Coronary Syndromes, and radial access was used in 97.6%. Baseline characteristics were comparable between groups.</span></span></span></p> <p style="text-align:justify"><span style="font-family:Arial,Helvetica,sans-serif"><span style="font-size:16px"><span style="color:#000000">There were no statistically significant differences in patient radiation exposure (305 mGy vs. 338 mGy, p=0.06), fluoroscopy time (4.2 vs. 3.8 minutes, p=0.61), or contrast usage (70 mL vs. 60 mL, p=0.11). There was a slight trend toward higher exposure dosage (p=0.06), that we believe is related to a change in the fluoroscopy protocol that was implemented shortly before the<em> CATHPAX</em>, since it is not accompanied by an increase in fluoroscopy time. </span></span></span></p> <p style="text-align:justify"><span style="font-family:Arial,Helvetica,sans-serif"><span style="font-size:16px">The average number of procedures performed per 6-hour period was comparable between groups <span style="color:#000000">(5.0 vs. 5.0, p=0.99), including (3.6 vs. 3.8, p=0.08) diagnostic angiograms and (1.4 vs. 1.2, p=0.17) angioplasties, respectively.</span></span></span></p> <p style="text-align:justify"><span style="font-family:Arial,Helvetica,sans-serif"><span style="font-size:16px"><span style="color:#000000">Complications were comparable (p=0.65), with three in the pre-cabin group (two distal perforations, one cardiorespiratory arrest) and one distal perforation post-cabin.</span></span></span></p> <p style="text-align:justify"> </p> <p style="text-align:justify"><span style="font-family:Arial,Helvetica,sans-serif"><span style="font-size:16px"><span style="color:#000000"><strong>Conclusion:</strong></span></span></span></p> <p><span style="font-family:Arial,Helvetica,sans-serif"><span style="font-size:16px">Our study demonstrated that the use of the radiation protection cabin is safe and does not significantly impact the cath lab workflow</span></span></p> <p style="text-align:justify"> </p>
