Thrombin generation and bleeding in cardiac surgery: a clinical narrative review.

This narrative review discusses the role of thrombin generation in coagulation and bleeding in cardiac surgery, the laboratory methods for clinical detection of impaired thrombin generation, and the available hemostatic interventions that can be used to improve thrombin generation. Coagulopathy after cardiopulmonary bypass (CPB) is associated with excessive blood loss and adverse patient outcomes. Thrombin plays a crucial role in primary hemostasis, and impaired thrombin generation can be an important cause of post-CPB coagulopathy.

Transcatheter Aortic Valve Implantation versus Surgical Aortic Valve Replacement: Meta-Analysis of Clinical Outcomes and Cost-Effectiveness.

Objective: Transcatheter aortic valve implantation (TAVI) has emerged as a feasible alternative treatment to conventional surgical aortic valve replacement (AVR) for high-risk patients with aortic stenosis. The present systematic review aimed to assess the comparative clinical and cost-effectiveness outcomes of TAVI versus AVR, and meta-analyse standardized clinical endpoints.

Methods: An electronic search was conducted on 9 online databases to identify all relevant studies.
