Our Structural Heart and Valve Disease Team

It takes many different types of heart specialists to diagnose and treat structural heart and valve disease. At the Swedish Cherry Hill Campus in Seattle, Wash., the Structural Heart and Valve Disease Program creates an environment in which these physicians can work together to evaluate, diagnose and treat patients with structural heart disease.

You may meet with one or more team members to discuss your options and to determine the care that is best for your particular needs. A representative from your team will contact you at regular intervals to:

  • Update you on the process
  • Schedule appointments
  • Answer your questions
  • Ensure your care is carefully coordinated
