  • Patients suffering from active infection on antibiotic therapy.
  • Patients with known intracardiac mass (right atrial or right ventricular).
  • Patients who are candidates for listing for heart transplant if it is deemed that they may receive a heart within the next 6 months.
  • Patients who have had an intracardiac lead implanted in the right side of the heart in the last 6 months.
  • Patients with any terminal illness, or with a life expectancy of less than 6 months.
  • Patients that are unable to lie flat for the duration of the procedure.
