Patients with severe AS should be evaluated by a multidisciplinary Heart Valve Team when intervention is considered. It is important to have a pathway to schedule the appropriate patient for this procedure.

Heart valve team

Patients with severe AS should be evaluated by a multidisciplinary Heart Valve Team when intervention is considered.
Team members include:

  • Cardiology Valve Expert
  • Cardiovascular Imaging Expert(s)
  • Interventional Cardiologist
  • Cardio-Thoracic Surgeon
  • Cardiovascular Anesthesiologist
  • Valve Clinic Care Coordinators

Their specific tasks are:

  1. Review the patient's medical condition and the severity of the valve abnormality
  2. Determine which interventions are indicated, technically feasible, and reasonable
  3. Discuss benefits and risks of these interventions with the patient and family, keeping in mind their values and preferences.

Post TAVR Management
❑ Early Post TAVR
• Postprocedure monitoring and pain management
• Early mobilization and discharge planning
• Monitor for conduction abnormalities
❑ Long term Management
• Antithrombotic therapy and endocarditis prophylaxis
• Management of concurrent cardiac disease
• Post-TAVR complications

Cardio-vascular Imaging
