Objectives
Objectives

  • Compare the surgical risks of first time AVR vs. re-operative AVR in 1213 consecutive unselected patients.

  • Determine the risk factors that predict mortality in this series.

  • Assess the clinical risk of reoperation AVR compared to long term anticoagulation.

The Risks and Benefits of Reoperation Aortic Valve Replacement


Risk of anticoagulation related hemorrhage
Risk of Anticoagulation Related Hemorrhage

  • The composite linearized rate of anticoagulation related hemorrhage in several large series averages 0.9 – 2.5% per year.

Conclusions
Conclusions

  • The risks of re-operative AVR are low

  • The risks of long-term anticoagulation are known

  • We encourage all adult patients to choose the risks and benefits of tissue vs. mechanical AVR based upon a thorough discussion of these risks

The Risks and Benefits of Reoperation Aortic Valve Replacement


Prosthesis selection
Prosthesis Selection

“ The choice of one type of valve versus the other is largely based on the surgeons’ or cardiologists’ views on what is the least harmful for the patient-anticoagulation for life, or the risk of reoperation.”
