Utilization of Bivalirudin as an Alternative Treatment for Suspected Heparin Resistance

Overview

This case study demonstrates the use of bivalirudin in a patient with suspected heparin resistance and recurrent intra-stent thrombosis during complex PCI. The switch to bivalirudin resulted in rapid therapeutic anticoagulation and a reduction in thrombus burden.

Background

Heparin resistance (HR) is a challenge in percutaneous coronary interventions (PCI), leading to inadequate anticoagulation and increased risk of thrombotic complications. Understanding alternative anticoagulation strategies, such as bivalirudin, is crucial for managing patients with HR during complex PCI scenarios.

Data Highlights

ParameterValue
Cumulative UFH Dose11,000 U
ACT before UFH118 s
ACT after UFH132 s
ACT after bivalirudin320 s

Key Findings

  • Bivalirudin was used as a rescue therapy for refractory heparin resistance during PCI.
  • The patient experienced recurrent intra-stent thrombosis despite aggressive antiplatelet therapy.
  • Switching to bivalirudin resulted in rapid achievement of therapeutic anticoagulation.
  • Marked reduction in thrombus burden was observed after the switch to bivalirudin.
  • Heparin resistance can lead to catastrophic thrombotic complications during PCI.

Clinical Implications

This case highlights the use of bivalirudin as an alternative in managing heparin resistance during complex PCI.

Conclusion

The use of bivalirudin in this case illustrates its application for managing heparin resistance in high-risk PCI settings.
