What is the recommended management for a patient with a prosthetic heart valve and an INR of 3.0 requiring surgery?

In managing a patient with a prosthetic heart valve who has an INR of 3.0 and requires surgery, it's crucial to minimize the risk of thromboembolic complications while ensuring proper antibiotic prophylaxis due to the increased risk of infective endocarditis associated with dental procedures.

Administering Amoxicillin or Vancomycin provides essential antibiotic coverage to prevent bacterial infection, especially in patients with prosthetic valves. The high INR indicates that the patient is at an increased risk for bleeding, which necessitates caution during surgical procedures. Careful suturing would help in managing this risk effectively while proceeding with the surgery.

This comprehensive approach combines the need for antibiotic prophylaxis due to the patient's cardiac condition and infection risk with responsible management of anticoagulation. Other options might not adequately balance the need for infection prevention while ensuring safe surgical practice.
