HEAL-IST IDE prøveversjon

3. november 2026 oppdatert av: AtriCure, Inc.

Hybrid epikardiell og endokardiell sinusknutesparende ablasjonsterapi for upassende sinustakykardi

Inappropriate Sinus Tachycardia (IST) is a prevalent and debilitating condition in otherwise healthy younger patients, resulting in significant loss of quality of life, lacking effective treatment options or systematic clinical evidence to support a therapy. The primary objective of this clinical trial is to evaluate the safety and effectiveness of a hybrid sinus node sparing ablation procedure for the treatment of symptomatic drug refractory or drug intolerant IST.

  7. Presence of supraventricular or ventricular tachycardia
  8. Presence of Postural Orthostatic Sinus Tachycardia (POTS)
  9. Presence of congenital heart disease
  10. History suggestive of secondary cause of tachycardia such as pheochromocytoma, anemia, thyrotoxicosis, chronic fever of unknown origin, COPD, long-term bronchodilators use, severe asthma or carcinoid syndrome
  11. Subjects who have had a previous catheter ablation in the right atrium for IST or other disorders
  12. Life expectancy < 24 months
  13. Pregnant or planning to become pregnant during trial
  14. Subjects with substance abuse
  15. Subjects with previous weight loss surgery
  16. Subject is unwilling and/or unable to return for scheduled follow-up visits
  17. Current participation in another clinical investigation of a medical device or a drug, or recent participation in such a trial that may interfere with trial results
  18. Not competent to legally represent him or herself (e.g., requires a guardian or caretaker as a legal representative) and;
  19. Presence of other anatomic or comorbid conditions, or other medical, social, or psychological conditions that, in the investigator's opinion, could limit the subject's ability to participate in the clinical investigation or to comply with follow-up requirements, or impact the scientific soundness of the clinical investigation results
