Experience with the Cardiva Boomerang Catalyst system in pediatric cardiac catheterization.
OBJECTIVE
We studied the safety and efficacy of the Cardiva Boomerang Catalyst vascular closure system in pediatric patients after cardiac catheterization with access in femoral and internal jugular vessels.


BACKGROUND
Recurrent catheterization and advances in pediatric interventions increase the need for easy hemostasis without a residual foreign body that may prevent re-accessing the vessel. The Boomerang can be deployed in sheaths as small as 4Fr without residual foreign body, with minimal orientation needed, and few complications reported.


METHODS
In a two-month period, all patients between 18 months and 21 years old catheterized with 4-8Fr sheaths less than 15 cm long were eligible for Boomerang placement. These were compared retrospectively with control patients with manual hemostasis. Anthropomorphic measurements, procedure type, activated clotting time, and sheath size as well as total times of cases, intubation, hemostasis, and extubation were compared between the two groups.


RESULTS
Forty-six Boomerangs were deployed in 31 patients and compared with 40 patients with manual hemostasis. Boomerangs were deployed in femoral vessels and the internal jugular vein. Device success with hemostasis was achieved in 39 patients (85%). There were no significant differences in time to hemostasis or extubation between the two groups. No major complications or operator error occurred, including hematoma, transfusion, retroperitoneal bleed, infection, vessel occlusion, or need for surgery.


CONCLUSIONS
The Boomerang is a safe and easy means of achieving hemostasis in the pediatric population, in femoral vessels as well as internal jugular veins. Its times to hemostasis and extubation were not significantly different from manual hold.
