Not Applicable

Completed

• Conditions: Heart Failure
• Interventions: Device: IASD System

• Registration Number: NCT01570517
• Lead Sponsor: Corvia Medical

Brief Summary

The purpose of this study is to evaluate the safety and potential benefits of the interatrial septal defect (IASD) System in patients with heart failure with preserved ejection fraction.

Detailed Description

The study was a multi-center, non-randomized feasibility evaluation of the IASD System at three centers in three countries (Denmark, Australia, and Czech Republic). Relevant ethics committee and competent authority approvals were obtained. The study was conducted in accordance with the Declaration of Helsinki. The protocol required the treatment of a minimum of 5 patients, and allowed up to twenty patients to be enrolled.

The primary objective of the trial was to evaluate the safety and potential benefits of the IASD Device System in the treatment of patients with symptomatic heart failure with preserved ejection fraction, despite optimal medical management.
