NCT ID: NCT04713683 Recruiting - Clinical trials for Foramen Ovale, Patent

Investigation of Nickel Sensitization After Percutaneous Implantation of Patent Foramen Ovale Occluder

INSPIRE
Start date: December 10, 2020
Phase: N/A
Study type: Interventional

Percutaneous PFO closure has been established as a first-line therapy for preventing recurrent strokes in selected patients. The devices used for the specific purpose contain and release nickel, which is considered as the most allergen metal in nature. Skin patch tests are considered as gold-standard for documenting nickel allergy. While the allergic contact dermatitis induced by nickel is well described, literature is inadequate on explaining the effect of nickel release on the clinical manifestations of patients implanted with such devices. Our prospective, randomized, blinded trial will try to investigate the above by performing nickel skin patch tests to all patients, 14 days before and 90 days after the implantation. During follow-up, clinical manifestations and transthoracic echocardiographic findings will be evaluated and associated with patch skin tests.
