PURPOSE: To prospectively assess the safety and efficacy of a novel absorbable vascular closure device (ExoSeal) in patients undergoing cardiac catheterization with femoral access compared to the established collagen-based (Angio-Seal) and suture-mediated (ProGlide) closure devices.

METHODS: This prospective, observational, dual-center, non-randomized, non-blinded study enrolled 1013 patients (65.1 ± 11.8 years) undergoing cardiac catheterization via a common femoral artery access in which hemostasis was achieved using a vascular closure device (255 Angio-Seal, 258 ProGlide, and 500 ExoSeal). In hospital complications (bleeding, hematoma, pseudoaneurysm, vessel occlusion, dissection, and arteriovenous fistula) of the puncture site and device failures (persistent bleeding) were recorded and compared for ExoSeal vs. the established devices (Angio-Seal + ProGlide).

RESULTS: There were more complications after utilization of ExoSeal compared to established devices (3.6% vs. 1.2%, p=0.012). No significant difference was observed in the device success rate between the established vascular closure devices (96.3%) and the novel device (94.8%, p=0.28). Considering each closure system, Angio-Seal had the lowest complication rate (0.4%) and the highest efficacy (99.2%); the latter differed significantly from ExoSeal (94.8%, p=0.001). Logistic regression analysis revealed a >3-fold odds of complications when using ExoSeal, which remained unchanged in multivariate analysis.

CONCLUSION: Utilization of the novel vascular closure device is associated with a higher complication rate and a similar device failure rate compared to collagen-based and suture-mediated devices, with Angio-Seal having the lowest complication and device failure rates.
