About this study
Official title: Nickel Allergy With Septal Occluder Using Amplatzer and Helex Devices (NASAH) Trial
This study is for patients who have been diagnosed with either a Patent Foramen Ovale [PFO] or an Atrial Septal Defect [ASD]. These are a type of hole located in the wall that separates the top two (2) chambers of the heart. You have been recommended to receive an atrial septal occluder device [a device specifically designed to close PFOs and ASDs] implanted in your heart to close this hole. Because these devices are made of materials that contain nickel, this trial is being conducted to perform blood nickel tests on those patients already referred for an atrial septal occluder device such as yourself. The purpose of this study is to compare levels of nickel in the blood in patients receiving either the Amplatzer or the Helex devices.
Read the detailed description
This is a single-center, single-operator, investigator-initiated, investigator-funded, open-label, non-randomized cohort study. Inclusion criteria include patients ≥18 years, secundum atrial septal defect (ASD) ≤1cm on transesophageal echocardiography or patent foramen ovale (PFO), without contraindications to antiplatelet and/or antithrombotic therapy, and suitable anatomy for device closure with one of the following: Amplatzer atrial septal occluder, Amplatzer Cribriform septal occluder, Amplatzer PFO occluder, or the Gore Helex septal occluder. After device implantation, routine clinical followup will be performed, including transthoracic echocardiography at 1 day, 1 month, and 6 months, and 48-Holter monitoring for arrhythmia at 1 month.
Research related study procedures are blood draws to measure nickel levels and a patient questionnaire about symptoms. Blood draws will be done at baseline [from the femoral venous sheath immediately prior to device implantation] and at one (1) day, one (1) month, three (3) months and six (6) months. The Questionnaire will be completed at one (1) month, three (3) months and six (6) months but can be done over the telephone if patient is having blood drawn at a lab closer to their home. Patient participation is complete after collection of the 6 month blood results and patient questionnaire.

The record says: stopped early, as of the sponsor's last update on 15 May 2013. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
The study was stopped early (reason given: PI re-located.). Results are not available in the source record.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
The difference in serum nickel levels (time frame: 1 month post device implantation). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 15 May 2013.
