Heparin Induced Thrombocytopenia In The Setting Of Urgent Cardiac Surgery: Can Bivalirudin Be A Safe Option? - A Case...

Area of Science:

• Cardiovascular Surgery
• Hematology
• Anesthesiology

Background:

• Unfractionated heparin is standard for anticoagulation in cardiovascular surgery.
• Heparin-induced thrombocytopenia (HIT) presents significant anticoagulation management challenges during cardiac surgery.
• Bivalirudin offers an alternative anticoagulant option in the perioperative setting.

Purpose of the Study:

• To present a rare case of a patient with HIT and cardiogenic shock requiring bivalirudin during urgent cardiac reoperation.
• To highlight the safety and feasibility of using bivalirudin in high-risk HIT patients undergoing complex cardiovascular procedures.

Main Methods:

• Case report of a patient with recurrent mitral valve dysfunction and HIT.
• Perioperative management utilizing bivalirudin as the primary anticoagulant.
• Adherence to institutional protocols for anticoagulation management in HIT patients.

Main Results:

• Successful use of bivalirudin in a high-risk patient with HIT and cardiogenic shock.
• The patient underwent urgent reoperation for mitral valve dysfunction without thrombotic or bleeding complications attributed to bivalirudin.
• Demonstrated the potential safety of bivalirudin in this challenging clinical scenario.

Conclusions:

• Bivalirudin can be a safe and effective anticoagulant alternative for patients with HIT undergoing cardiovascular surgery.
• Careful patient selection and adherence to institutional protocols are crucial for successful bivalirudin use in high-risk HIT patients.
• This case supports the consideration of bivalirudin in complex cardiac surgical cases involving HIT.
