Conditions
Brief summary
This is a three-arm, randomized multicenter study evaluating the safety and effectiveness of EVARREST™ Fibrin Sealant Patch in controlling mild to moderate vascular anastomosis suture line bleeding in cardiovascular surgery.
Interventions
EVARREST™ Fibrin Sealant Patch is a sterile bio-absorbable combination product consisting of two constituent parts- a flexible matrix and a coating of two biological components (Human Fibrinogen and Human Thrombin).
Equine collagen with Human Fibrinogen and Human Thrombin
SoC is a composite of techniques/methods typically used by the surgeon to control bleeding after conventional methods (i.e. suture, ligation, cautery) are ineffective or impractical.
