What is the recommended management plan for a patient after a Surgical Aortic Valve Replacement (SAVR)?

Management Plan for Patients After Surgical Aortic Valve Replacement (SAVR)

The recommended management plan for patients after SAVR should follow the same core principles as TAVR management, including periodic valve function monitoring, comorbidity management, cardiac conduction monitoring, lifestyle optimization, appropriate antithrombotic therapy, endocarditis prophylaxis, patient education, and cardiac rehabilitation. 1, 2

Follow-up Schedule

• 30 days post-procedure: Evaluation by surgical/valve team
• 6 months: Follow-up with primary cardiologist
• Annually thereafter: Continued cardiology follow-up
• 3 months: Primary care physician evaluation, then as needed
• More frequent follow-up for symptom changes or conduction abnormalities

Antithrombotic Management

• For bioprosthetic valves:

  • Aspirin 75-100 mg daily lifelong 1, 2
  • Clopidogrel 75 mg daily for 3-6 months 1
  • Consider warfarin (INR 2.0-2.5) if at risk for atrial fibrillation or venous thromboembolism 1

• For mechanical valves:

  • Lifelong warfarin with target INR 2.0-3.5 2
  • Consider anticoagulation self-management which has been shown to improve INR profiles and reduce thromboembolic events 3

Monitoring and Testing

• Echocardiography:

  • At 30 days post-procedure
  • Annually thereafter to assess valve function, regurgitation, and gradients 1, 2
  • Baseline values to monitor: mean effective orifice area ~2.0±0.5 and mean aortic gradient ~13-14 mmHg 4

• Electrocardiogram:

  • At 30 days post-procedure
  • Annually or with symptoms
  • Consider 24-hour monitoring if bradycardia is present 1, 2

• Laboratory monitoring:

  • Regular blood counts, metabolic panel, renal function 1
  • More frequent INR monitoring for patients on warfarin

Comorbidity Management

Focus on management of:

• Coronary artery disease
• Hypertension
• Heart failure
• Arrhythmias (especially atrial fibrillation)
• Assessment of pulmonary, renal, GI, and neurological function annually 1

Infection Prevention

• Encourage optimal dental care
• Antibiotic prophylaxis per AHA/ACC guidelines for all prosthetic valves 1, 2
• Maintain anticoagulation with local hemostatic measures during dental procedures 2

Rehabilitation and Lifestyle

• Early mobilization post-procedure
• Cardiac rehabilitation program enrollment
• Promotion of physical activity as appropriate
• Cardiac risk factor reduction and healthy lifestyle 1

Long-term Considerations

• Valve durability: Bioprosthetic valves typically last 10-15 years 2
• Reintervention planning: Patients with life expectancy beyond a valve's durability should be counseled about potential future procedures 5
• Economic benefits: SAVR for symptomatic aortic valve disease is associated with improved mortality and lower annualized healthcare use and costs 6

Coordination of Care

• Ensure communication between surgical team, primary cardiologist, and primary care physician
• Patient education about valve-specific precautions, anticoagulation management, and signs/symptoms requiring medical attention

Potential Complications to Monitor

• Valve thrombosis or dysfunction
• Paravalvular leak
• Endocarditis
• Bleeding complications (especially with anticoagulation)
• Heart block or arrhythmias
• Heart failure

The management approach should be tailored based on valve type (mechanical vs. bioprosthetic), with particular attention to anticoagulation needs and monitoring frequency.
